I have had my new Galaxy Note 3 for about 3 weeks now, and have had an issue with certain apps not connecting to the internet over wifi. All of the google apps (youtube, play store, hangouts, gmail, etc) are not able to connect to the internet over any wifi hotspot, or if they do, they're painfully slow.
I have changed MTU settings on my home router, DNS settings, wifi auto switch is off on the phone.
Here's the kicker. If I enable airplane mode first, then turn wifi on, everything works great. I suspect this to somehow be related to the SIM card? Really should have nothing to do with wifi, but who knows...
I should add that I've owned a couple other android phones that have had this issue, but it seemed to have just "worked itself out" after a day or so. (Droid 4, Stratosphere II)
Have you tried a 30/30/30 hard reset on the router yet?
Does a laptop connected via Wi-Fi also have similar issues?
Sent from my SM-N900V using XDA Premium 4 mobile app
I have hard reset and factory reset the router a few times, even went so far as to buy a brand new router and use it. No difference.
I get 26/8 speeds on two different laptops, and one desktop, all with ping times down to about 18ms (as shown on speedtest.net)
spoke with a helpful rep at verizon today, who supposedly called samsung regarding this fix while I was on hold. My replacement should be here tomorrow. This issue is exactly the same as when older android phones would not connect to google (signal indicators would be white instead of blue). It seems like something to do with ssl traffic.
Anyhow, will post back after i've played with the replacement for a bit.

The next most common thing that it would be is the channel that your router is set to. You want to use a frequency that has little interference and there is an app called WiFi Analyzer to help figure it out for your surroundings.
The reason that the laptops might work ok is because the channel can be set within Windows and are most likely set to a different random number between 1-11 than your phone is.
I have found open channels and used those, which made no difference. I believe this may be a google issue as evidenced here (granted these guys are talking about the nexus 5, the issue is very much the same)
https://productforums.google.com/forum/#!topic/nexus/SN03aclu7B8[1-25-false]
I received my replacement today, no dice. I also bought a new router today, no dice. I've tried every channel 1-12, no dice.
The only thing that works is to enable airplane mode, then turn wifi on. I then see full speeds on play store, youtube, gmail, and hangouts. Interestingly enough, the facebook app is affected by this, as well as all push notifications.
It should be noted that the replacement note 3 exhibits the exact same behavior. This leads me to believe there is a modem issue causing the phone to switch back and forth between LTE and wifi, or something along those lines (if the cell radio is off, wifi works great)

That is truly odd. I suppose it could be believable that an ISP throttled traffic to specific blocks (net neutrality anyone?), but I don't know why that would cause an interface change on the handset.
There are some apps which are network interface aware - e.g. as an example carriers will use split DNS and inbound IP firewalling so only people on their own network can resolve the IPs of MMS (APN) servers or *send* data to them. That prevents them from being DDOS'ed and I suppose other attacks from anything but their own network - which they have well instrumented. But that means that the MMS apps can not use whatever IP interface happens to be up - either for DNS service or for IP routing - so they need to be able to bring up a specific IP interface, use DNS that is bound through that interface, and route through that interface as well.
I was going through the apps on my phone the other night with a package browser (Package Explorer (Ribo), btw) and I was stunned at how many apps have "CHANGE_NETWORK_STATE" privileges.
What I'm wondering is if you have an app installed that has gone nuts and is toggling on/off your cell I/F. Something like that would be consistent with your observations.
Is there anything relevant happening in your device logcat when this is going on?

There are no apps installed other than the stock verizon/samsung apps. I have reset to factory in preparation for sending this unit back to vz, however it appears i'll be keeping it since the replacement didn't work any better.
Nothing interesting from logcat. Just a lot of IRListener messages, and DalvikVM occasionally clearing ram.
I can see why you would be pulling your hair out.
And the fact that you observe the same behavior with two different units (completely different hardware) and two different routers means one of two things:
- the problem is the handset/software
- the problem is not the handset/software.
Not trying to be funny there. What I mean by the above is that for you to pull two devices out of Samsung's production line at random (unless you happened to get two devices from a single batch of defective units), then the problem couldn't possibly be a low-probability defect thing: either it happens on a very large fraction of all N3 handsets, or the problem actually has nothing to do with the handset at all.
e.g. suppose Sammy shipped handsets where 1 out of 100 had the problem you observe. For you to end up with two of them in a row, the odds of that happening would be 1 in 10,000. If affected half of all handsets, then your odds would be more reasonable - 1 out of 4.
But it sure seems like if it affected half of all owners... or even 10% of all owners, people would be piling in in droves to complain.
I haven't noticed it on my N3, but I have other devices so I'm not sure how much I have used it for e.g. Youtube streaming. I do leave both WiFi and the cell on, and haven't noticed what is happening to you, but I am on MJ7 instead of MJE, and my WiFi is older (802.11g), so maybe if it is a bug it that wouldn't even show up with my setup even if it were the N3's fault.
(BTW, that offers a suggestion - because the N3 is so new it has 802.11ac capabilities - and I suppose your new router does too - if you turn off some capabilities, does the problem disappear? For instance turn off 802.11ac or 802.11n or 5Ghz band usage on the router, does that change anything?)
The other alternatives? Some kind of burst RF noise in your local environment? You earlier said
are not able to connect to the internet over any wifi hotspot, or if they do, they're painfully slow.

were the "any wifi hotspot" APs that were all relatively close to a single location, or were they widely dispersed (miles apart)? If they were miles apart, then the problem isn't ISM-band interference. Even if it were, interference from non 802.11 devices (bluetooth devices, baby monitors, microwaves, some wireless cameras, etc) isn't going to show up using a scanning app. Relatively sophisticated equipment would be needed to make that determination. Or a search and destroy mission.
I will say that I had a similar problem a few weeks back (using completely different gear) - I was tethering to a different Android phone (USB tether), and Web browsing on the client device (N7 tab) was fine except the Google Play store app - data would only come dribbling out of it. I couldn't even complete a single app listing, much less begin an app download. At the time I just chalked it up to a temporary problem with Google's Play store. But now it makes me wonder if it isn't something more subtle - as you noted, Google servers seem to be a commonality you are observing. Maybe some ridiculous bug involving Google's single credential efforts?
Well, now I'm rambling and I really haven't given you a suggestion. Maybe something I said will jog you in a different direction and you'll figure it out. If it really is something generic to the current Note 3, it seems like Google would want to know about it. I wonder if it is even possible to get telephone support from Google - they don't really have a reputation as being a consumer-oriented business.
good luck

Thank you for all of your help. I am sort of an amateur RF "enthusiast" myself. This happens in more than one location, literally every wifi location i've connected to.
I do believe on past handsets a new sim card sorted this out for some reason, however the vz rep that I spoke with activated a new one that I had gotten with the note 3, but not activated at the time, since my droid 4's sim card was "current enough".
I am lead to believe that this is a modem firmware issue, due to the fact that when the cell radio is off (doesn't matter if mobile data is on or off) the wifi works great. I am running MJE, and would be willing to try and downgrade to the previous radio to see if it makes a difference, but I don't know if that's even possible without causing some damage.
edit: I just realized that the replacement phone is running MJ7...so not sure it would matter.
Resolved
Ok guys, I figured this out, sort of.
I went into an angry router swapping/resetting frenzy when I figured out that the replacement acted the same.
My original setup consisted of: (I have a lot of wired devices in my house)
Comcast Gateway (set up as a normal cable modem, wifi/firewall/dhcp disabled) ----> Linksys WRT54G w/ DD-WRT (wifi off, using for firewall/routing) -----> Zonet N router (no dhcp, using as a switch, wifi off) --------> Linksys BEFW11S4 (used as a switch) ------> Netgear WNR1000V2 (used as a switch and second wifi access point occasionally)
During this frenzy, I eliminated the Zonet unit, and the BEFW11s4. My network now looks like this:
Comcast Gateway ----> Netgear WNR1000V2 (router/firewall/dhcp/wifi access point) -----> WRT54G (as a switch)
This seems to have solved my problem. I noticed while troubleshooting that if I disconnected the segment between the Zonet and the BEFW11S4, my phone would work perfectly fine. I believe that taking the BEFW11S4 out of the picture solved my problem, even though my data was not riding on that segment of the network.
Still, I am perplexed as to why the airplane mode trick fixed the issue.
LOL. I have a pile of Cisco routers if you want to buy them - and I'll throw in some token ring gear and another BEFW11S4 for free.
But seriously - you did the right thing by (experimentally) simplifying; the more complex an environment is, the more opportunities there are for bug expression.
Glad everything worked out - and I await your PM inquiring about my Cisco pile
I never wanted to upgrade from my WRT54G V1! What an awesome, rock solid router! However, need faster wireless speeds nowadays.
I was trying to keep that as my firewall, since the dd-wrt firewall is so much more robust than that of the netgear, also the netgear does not support nat loopback (something I really would like to have)

I gotta know if anyone else is having the same problems connecting to wifi as I am. Whenever I try to connect to my wireless network with any of my devices, it's sporadic. Sometimes it'll connect right away. Most of the time, it takes two or three minutes (!) and sometimes it'll puke on itself and say it doesn't see the network.
In the latter two cases, I can delete the profile for the network and power-cycle the device and it'll connect to the network almost immediately. As you might guess, this is an annoying process to go through.
It never really bothered me until my wife got an iPhone and it connected immediately to the network and does so EVERY TIME SHE USES IT!
Can anyone help me out? Why do these devices take so darn long to connect?
This is the second router I've used (first was a Linksys, currently I'm using a Trendnet), the Raphael (Fuze) and Tornado (SDA) are running their stock ROMs. The Wizard (MDA), I've gone a little flash-happy on, but I've encountered the same problem with all ROMs I've tried.
I'll admit I haven't checked what channels neighboring wifi networks are using (I'm pretty sure I'm the only one on my channel), but when I first got my Tornado and Wizard, mine was the only network (visible) and I was still having problems. And regardless, is the wifi radio in the iPhone that much better than my HTC devices?
(Just a side note, I have three wireless laptops that are all able to connect to the router without a hitch, adding to my belief that my network is on its own channel.)
Just wanted to update everyone that, last night, I checked the wireless networks I could see from my house and none share the same channel as mine, however I didn't take overlap into consideration. The lack of response to this thread would suggest to me I'm the only one encountering this type of problem, so I'll do some experimenting in an area with no other wireless activity and see if connecting is still slow.
O.K. I tested the Wizard and Raphael with a router in an area with no other wireless activity and discovered the following:
If the devices are set for DHCP, it takes a long time to connect. However, they did connect and remain connected without any problems.
If the devices have static IP addresses, they connect immediately and remain connected without any problems.
Conclusion:
The DHCP discovery on these devices takes too darn long to acquire addresses. That, and the slightest bit of EM noise can cause them to crap out. Since I don't have problems with other wireless devices (laptops, iPhone), I'm left with the assumption that either the radio is poor quality (unlikely) or the driver needs some serious fixing (most likely).
When and if the noble developers of this board get linux up and running on the Raphael, I'll be more than happy to test it out.
Since this thread was self-answering and would seem to be of little value, please feel free to delete it, moderators.
This is driving me insane!
When I have WiFi enabled at the office, my Samsung Galaxy Note (stock ICS, rooted) constantly receives incoming data and I haven't got a clue which setting, app or service is causing this.
SystemPanel registers a nonstop stream of incoming traffic at 8 to 10 Kbps.
TrafficStats shows an accumulation of Received data under Total WiFi, but can't seem to link it a particular app or service: after resetting the data, no processes appear but the incoming data keeps on growing.
All sync options are off, I've tried to kill every running app or service (one by one, all at once), I've tried to block all traffic using Droidwall. As soon as WiFi is enabled, the incoming stream is unstoppable. When switching to 3G, there's no incoming traffic.
But to make matters even more mysterious, I do not have this problem with my WiFi connection at home.
It only occurs at the office, only on WiFi and (as far as I know) only on my phone.
Any ideas?
This is simply because your wifi antenna still "hears" the data going trough the wireless network on wich you are connecter. Event if your phone doesn't asks for any data at the moment the traffic there is on the network will still be counted by the wifi chip on your phone.
It will be the same on any public network or if you have another phone or a computer connecter on the same wireless router and generating traffic.
Thanks for replying, John!
That sounds very plausible, but then I still have to figure out why only my phone is registering this traffic - maybe it's an ICS thing or brand specific?
And I'll try to 'reproduce' it at home by connecting a laptop at the same time.
I think that the above is correct. That may be default behavior.

Well, I've tried to connect several devices at once on my home WiFi network, but it did not reproduce the incoming traffic problem I experience at work.
There were a few incoming bytes registered, not nearly as much as the constant stream of 10 Kbps at the office network...
Your works wifi may be set up like that. Who Knows?

About this, it is simply that at your office there is traffic on the network (download/upload) while at home simply having devices connected doesn't generate traffic or almost none. Start several dl on several devices (phone laptop) (guess 2-3 is enough, maybe even one but not sure, not en expert after all ) then you should notice signifficant traffic on your phone, I guess!
So interesting I find this thread because I have the exact same problem!!!!
How I noticed it...when I am at home I drop 1% battery on Wifi per hour. 10hours = 10% (sometimes less).
I go to work on the Wifi, I DONT USE ANYTHING ON THE PHONE and the battery is DRAINING LIKE CRAZY!!! 5%/h or more!!!
( I am in airplane mode in both place)
So I was thinking, WTF with this work wifi, i am not doing anything at all on it. Then I look at my wifi icon I have a constant RECEIVE icon. And I bet my phone does not go to sleep or something.
So why in the world my work wifi is draining my battery and the one at home is not. I will check tonight but I dont think I have traffic like this. I am registering 5-6kbytes/s for nothing. The explanation given above is hands-waving. I do not agree with it fully. YEs sure there are several pings and beacon emitted back and forth but i do not think it is enough to cause 5-6kbytes/sec . The wifi is not in Monitor mode and it only receives the packets destined to my phone.
This is madness!!!! BTW When I had a different kernel on back on ICS this behavior stopped. I will try to monitor again.

Hey kalinusa, did you find a solution to this problem?
I'm currently on the SpeedMod kernel, but that does not seem to make a difference to the 'office WiFi behavior' (so I keep my phone on mobile data).
I don't want to speak out of my ass, because I haven't a clue how the app works.
As far as I can guess SSH tunnel may help you. I would hope someone else could tell me I'm right, but I'm probably wrong.
I have had this same problem with two of my devices. The first is a Samsung Captivate with the last AOKP ICS build. The second is a Google Nexus 7 with AOKP's first Jelly Bean build (it happened when I had stock as well).
This only happens when I'm connected to WiFi at my university. The down arrow on the WiFi icon is ALWAYS on and it drains the battery. At home, I don't have these problems.
I emailed my university's IT department but I'm not sure if there's anything they can do. Anyone have any suggestions? Thanks.
I have exactly the same problem, but I think I found the reason which is causing it. I think that some of the routers are capable of the multicast over the wifi and then we can get a constant wifi traffic. I tested it at home, where I have enabled multicast over wifi and my phone wifi receiving the data all the time, even if it is in sleep. Now I'm in the office where we do not have such capable router with multicast over wifi and my phone wifi behavior is as expected. When I will be at home I will test it again with my router and with disabled multicast over wifi and hopefully it will solve this issue.

More than multicasts it could be broadcasts, what are you reaceiving. For example if you don't use WINS server in Windows domain, all computers use broadcast to get IP address for a computer name (if you dont use DNS name, but that's another story). At home, where aren't many computers, there are very few broadcasts. But somewhere, where a large amount of computers is on the same network (not splitted to broadcast domais), number of broadcasts would dramatically increase
btw. if you connect a PC to the same network as your phone and stop ALL running applications (mainly instant messangers, web browsers, e-mail clients) you should see the same network bandwidth in use as on your cell phone.

It depends on what you consier as network load. If you start a network monitor like Wireshark or MS Network monitor and even if there is one computer on the network, you wil see "some" traffic (from time to time a few network packets). To generate constant network load, you'll need a few dozens of computers. And it always depends on how the network is designed and what applications the computers run. If all computers connect to a server, the network load will be a lot lower than if the computers share resources among them.
Or you can design your network in such way, that you divide computers into segments, where computers can communicate only with computers in its segment (or with some distant servers). This way the network load will dramatically decrease, as computers from different segments would not interfere.
I currently only have one computer connected to my home network atm via wifi, and it keeps a constant broadcast going to my phone for some unknown reason. I thought it was my dlna server, so I shut that off, and it is still broadcasting _something_... Its causing quite a battery drain, and unfortunately I cant seem to find the root of the issue. I've trolled through my router settings -- multicasting isnt on -- so Im at a loss. =\

It can be caused also with the Media servers which runs on PC, also DHCP etc. It is not easy to eliminate all broadcast traffic and sadly our phones react at all that multicast packets.
Hey guys,
My nexus 10 had a gray Wi-Fi bar and is failing to connect any of the Google services such as play store, search app, or gmail. Basically GAPPS. I cannot find a solution to this besides factory resetting, can someone help? My tablet is on stock rooted.
Thanks!

My N10 either has a grey WiFi bar or it disconnects completely. This happens very often and occurs no matter what rom I have, even stock. I've always felt that the WiFi has always had issues but never got resolved. I've looked around for solutions but not found any. Much appreciated if someone explained or had a solution.

Toggle the Wifi off and then back on a few seconds later.
If this doesnt fix anything then you need to modify your router settings to be compatible.

No offense meant, but that's a pretty silly claim. The transmission technology involved (2.4GHz/5GHz) or protocol (802.11a/b/g/n/ac) has no bearing on the color of the Wi-Fi indicator, which indicates just one thing: does a request to Google's secure servers work, or not? It's virtually always a problem with the network setup, be it with the ISP or the router blocking a port. OP should try using a public access point (coffee shop or something) or mobile hotspot to see if they're able to connect that way.

None taken. I was under the impression that grey/no bars, meant that there was no signal or there was a connection issue. I had no idea that the wifi state on the tablet had anything to do with Googles secure servers. I would like to learn more about that, if you would be so kind.

The Wi-Fi state doesn't depend on the connection to Google's servers-- that's why it's quite possible to get full graybars. You'll also notice that if your Wi-Fi goes to sleep, when you wake up a (stock) Android device, you should basically always see it gray first, then turn blue after a second or so (speed depends on how good your connection is).
It's also not as simple as just going to google.com, because you can (usually) do that regardless of the status reported. That's because going to google.com only relies on basic HTTP/HTTPS web traffic through ports 80 and 443, which on most functioning networks are never going to be blocked (mostly because it would make even basic web browsing more or less impossible without workarounds). All of your "real" transactions with Google (Gmail sync, location reporting, etc.) happen through secured connections that run on different ports.
Some networks will block those ports for security reasons (the more ports you have open, the greater the network's functionality-- and its vulnerability to outside attack). In those situations, you'll see a gray bar indicating that while you've got connectivity, you won't be able to establish the connection to Google needed for some services to run (most importantly, any GCM/C2DM-based push notifications).
And no problem. Unfortunately, many OEMs muck around with the iconography, making this distinction meaningless on a pretty wide range of devices. It's annoying because this is one of the more common reasons that Google services don't work.

Would you happen to know if roms can affect wifi reception?

ROMs and kernels shouldn't affect reception in a technical sense (unless the kernel developer really messes up or something), but they will affect what your device can do with the signal it has. There are also various modes your device can follow that offer compromises (i.e. for CDMA devices, EVRC-B vs. EVRC-C -- one is better for normal usage, the other holds clearer calls with low signal).

Really appreciate the reply Rirere
I tried several lately. Since day one I have been receiving such poor reception. We have heavy wireless users here ranging from multiple game stations,phones tablets ,PC's etc. All have been receiving full strength except for the N10. From what your saying it seems like I have adjust the router for this one.

Could you be a little more specific? Android has some nasty Wi-Fi issues (never have as many on my iOS devices), but the situation you describe doesn't sound like it helps. I'm the student manager at a college helpdesk, so we sometimes have this kind of problem in the dorms. If you give some more info about your setup, I might be able to at least point you in the right direction.
Things like what's the make and model of the router, where it's located, how close are neighbors, and so on. You can also use this app (https://play.google.com/store/apps/...SwxLDEsImNvbS5mYXJwcm9jLndpZmkuYW5hbHl6ZXIiXQ) to see if there's channel interference. If your router is new enough, you could also potentially kick it up to use 5GHz only (although that causes lower speeds the further you get much faster than auto 2.4GHz/5GHz).

Your too kind Reiere Thank you,
I'm using a Media Link MWN-WAPR150N. I see, it doesn't support 5ghz which seems to be a total bummer. I could have sworn that I purchased a dual band model. It's a wonderful device as I'm not having to constantly power cycle it like in the past. We do catch a neighboring facility's wifi here on our devices so I believe this can be causing interference and it would be best to switch up to a 5ghz router? Definitely will check out the app. Thanks allot. I apologize for the ignorance in this area.

You're almost always going to get some degree of interference from other devices. How bad it is depends on the power of your neighbors' rig and its proximity. Other items, such as microwaves can cause temporary disruptions in wireless power, but it's much more unusual these days than it was in the past.
Given the way other devices in your network seem to be functioning alright, it might be a device-side issue. However, before that I would look into a Wi-Fi analyzing app like I posted earlier and try setting your network to a particular channel. If you pick one clear of your neighbors' wireless network, then if it's set to auto (which it probably is), it should adjust around yours and grant you a clear channel. (two networks on auto can occasionally snarl with one another, and the one with more power is going to win. Since yours is a single-band N home router, there's a good chance you'd lose with the routers out these days).
OK so device is a - LG D80210B - 16GB - UK - EE - UNLOCKED - ROOTED - StockMOD rom with update package. 4.5gb storage space left.
2nd device is a - HTC ONE 16gb - STOCK - NO ROOT
3rd device is a - SAMSUNG RV510 Laptop.
Im on EE uk network on both phones with EE ADSL Broadband at both mine and my partners house.
Now.... One would assume everything from the same company would be simple... If only that was the case! haha.:silly:
Now which ever property I visit within 15 - 20 minutes of being on the Wi-Fi the LG G2 kicks everybody out of the router, all at the same time. No one can access the network until one of 2 things happens... either I disconnect for 15mins plus or the router gets restarted nothing else will bring back the internet. Note - This does NOT happen when I am not present and surfing can be achieved all day on any device.
So ive spoken to the useless turds at EE technical support on the phone about 30 x they have absolutely no idea what the issue is but its definitely only related to my device. There suggestion is to cancel and go back to sky (which worked flawlessly previously to EE being installed). this is an option but it means another month with no internet at all and I also get an additional 10GB of 4GEE data on my phone allowance if I have there broadband so it would be beneficial to keep it.
Things ive tried;
Every different setting under the sun.
Different encryption.
Static IP addresses.
DCHP settings.
the brightbox will only broadcast internet on 2.4ghz as well if it helps anyone diagnose.
Using a known router as an access point to see if that solves the issue - again perfect until I log on.
Tech support.
Search the net and forums on here.
Spoken to a networking wizard mate of mine.
The problem seems to lie in the LG G2 and/or Jellybean firmware currently installed and installed as stock as the fault is not present when I log off the Wi-Fi...
So..... I decided to try a different rom, the Slim Kat rom
The Wi-Fi works flawlessly for me and everyone else however the rom is just too unstable at the moment to be a daily driver. It doesn't have the complete knock on knock off features and I don't really like the look I much prefer the stock rom as well as some of the games I play just will not work.
Now ive had and been flashing smartphones for about 8 yrs with the help of you lot on here leedroid especially was one of my faves so im not a novice or anything im just lost for what else to do or try????
Has anyone else experienced anything similar?! I would send it away to see if its a hardware fault but as it works perfectly on kitkat I assume its got to be some kind of bug in jellybean.
OR ive changed something that's ****** it up.
I would really appreciate any imput at all because I have a phone I cant use at my partners house or at home ...
Cheers brett
Just to add it also does it when Im on my own i.e. just the phone.
bump for today.... this is really breaking me now as no one can use the wifi for longer then 15 minutes lol
So theres not one single person that has even the faintest idea of what my issue may be?
Someone had this issue before, read about it. A router update fixed their issue. If setting device static, the router also needs to be configured to hold it, try this with all devices and lock local IP's. Next, leave a device off and see if it gets kicked. The G2 seems a bit picky with routers... On the Comcast Technicolor, it won't push past 3.5 dl, but max up. Some old drt firmware has problems as well.

Thanks for the reply dude...
Yeah tried to update it but its telling me its on the most recent software even though its date is 2010. Called tech support they say it up to date.
I can set the IP in the DHCP section of the router but I cannot for one second find out how to do it on the phone... do you know?
I used DHCP to assign a static IP to both phones, the Nintendo wii, the sky box and the laptop, so they always pick up that IP from the router without fail. I also set the DHCP settings so that it does not conflict with any of the locked IP's just incase - so DHCP is from 192.168.1.2 - 192.168.1.99
Its not a router problem as much as id like to blame it on that because I used my old known working sky router as an access point to connect to as well and that make absolutely no difference apart from slow it down because it doesn't support "N" mode.
Its an EE brightbox router - piece of *****
I can leave the other 4 devices connected to the router 24/7 with no issue until I connect the LG G2. Then all devices are booted at the same time usually 15-20 mins sometimes less. never more. it also only occurs when just the LG is connected. Like now my phone is stuck at recovery ATM (another problem im trying to solve) and the internet hasn't dropped once my partner is on it and so is the sky box so its DEFO my phone that's doing the bad.
That's ODD that isn't it my up and downstream in the router are both above 10meg although the attenuation and line noise keep changing.
cheers for the input
In wifi menu of phone, hold on connection and select modify. Check show advanced options, chose static, input data(along with password again). Reboot phone. After you fix it of course.

I ended up getting a new router that seems to be ok so far... what does that actually do? Thank you so much for it suggestions
Sent from my LG-D802 using xda app-developers app
Sets static for phone. Has to be set on both router and phone. I just found out the G2 has some issue with AES on certain routers. Try TKP only. I had to do this with my other Technicolor. Odd thing is AES works fine on the SB 6141. Lost on that one.
Had exactly the same issue with my shiny new G2. Using a Netgear modem/Router. I upgraded the firmware and that seems to have fixed it. It was killing the Router within about a minute of use. Now running 25 minutes without any drops. Fingers crossed it's permanent.

Hi everyone,
Without wanting to give away too many details, I work for a company that recently purchased some of these Huawei B882-66 LTE routers, as we have some clients who need to get on the internet in areas where it's not easy to get a real line. We set one up recently along with a laptop we provisioned for them - and there are some crazy download/upload values happening over the LTE data that are not only costing a lot - they should be impossible. I just came into this position, this having been done before my time.
Basically, ~6gigs is being downloaded over a course of 10 minutes without any activity being done on the laptop itself, there are no other connections to the router (wifi disabled, hard line), and since metering is enabled... I'm at a loss. The IP is charging for this data - so it's real data, not just some bizarre UI issue.
So here's what they did, basically:
Laptop:
- Laptop has Windows 10. Fully updated before provisioning, though another update dropped a few days later.
- Only Chrome and Firefox installed. No McAfee, no Office - nothing else. Windows 10, Chrome, Firefox. That's it. Bare bones.
- Metering set on the ethernet. So: Win 10 updates shouldn't be happening. Shouldn't.
Router:
- Wifi totally disabled. Hard line only.
- SIM card purchased by user through the IP. Administrative access to the account given to two other people - and we have been assured that their accounts were not migrated, their devices are not connected to this particular account. The only device on this account is this router, according to the IP... Whom, admittedly, I doubt.
- This router was purchased by a third party vendor and NOT through the IP. So, knowing Huawei's security issues, I'm raising one of my eyebrows very high in suspicion.
I don't have a lot of access here, because I'm not the IT guy, I just happen to know my way around. I would love to packet-sniff what this router is up to, but I basically don't have the time, and it's not my network so I don't want to step on toes. So I did pretty much the only thing I have access to right now - I took an old DLink we're not using, hooked it up to the WAN port of the B882, used an old laptop that I can safely wipe to get into the DLink's wifi, and watched the traffic over the hard line. There is NO SIM card installed at all. So, there is no chance for it to attempt to send over cell data.
It's attempting to send 1.52kb-2.10kb every 30 seconds through the WAN port, constantly. Now, I figured this is a "hello, where am I?" attempt or handshake... but there's no SIM card and no device connected to it, so doesn't that seem like a high amount of data to essentially contact nowhere, for no reason? Again - I'm not an expert. That's why I'm asking the forum where I found a hacking guide for a previous Huawei router.
Either way - the router we provisioned is sucking up cell data at an unbelievable rate. Their cap was 7gigs, and that was reached in 10 minutes through an already-updated bare-bones laptop. Nothing else is connecting to that router, period. Metering is enabled... But perhaps it's being ignored?
My worry is that those large chunks of mysterious data are Bitcoin blocks, or something to that effect. It's also sending at roughly 1/5 the rate it's downloading... To where, and why, I have no idea. Can I get some opinions on this? I think I'm just going to return and work with other routers, or maybe some simple USB sticks, but I would love some opinions.
