Wifi sucks :(

Hi all,
I just got my device, and still thinking whether to send it back in 7 days. My main complain is the wifi. I have never seen more than 2 bars (out of 4) signal strength, even when sitting 2 meters from the router. Moreover it always drops the connection. I realized it when I tried to use IE for browsing, since that doesn't tolerate it and I keep getting the connection lost messages. Seems that Opera can live with it, but I see when the connection dropped during the page load. Youtube watcher also cannot manage to download videos when the signal is dropped.
The Tx/Rx rate also changes chaotically from 1Mb/1Mb to 54Mb/36Mb.
Before you ask: the Power Mode of wifi is set to "Best Performance", since this is the only way it is usable.
Anybody else with similar experiences?
Any solution?
I really appreciate any help, I would like to keep it!

I have no problems what-so-ever with the wifi on my D2...
It runs very well, in all applications that can use it.
- and I have full signal when I am within 5 meters of the router.
I haven't changed any settings on the device, and the router is running on WPA2-PSK at a channel not used by any of my neighbours.
Maybe you have many wireless networks in your area?

Hi,
I have more or less your problems (I opened a thead about it the day I unpacked my D2 but wasn't really condiderated). Here's my condition: I have 3 HTC devices...Artemis-->regular functioning (balanced power), TytnII-->Power Performance MUST be set to high performance, Topaz..well I could connect with balanced power but since I upgraded radio I have to keep it set to best performance, otherwise I would get "fake" connections (connection established but no data taffic). I don't really bother to have to set it like that because the connection is dam fast, which compensates the higher power consumpion.But beside this, I must say that my router is not very friendly with my D2,e.g. when I don't get a connection,I restart it and it works (this must have to do with DCHP service). I have much less trouble connecting alsewhere. So ,what to say? Try to change radio...Do you have other wireless devices working regularly in the same area?Do you have an original rom?You could also try to change wifi channel..would be happy to help

Hi,
Thank you for the answer. I have original ROM, just checked the radio, it is: 3.43.25.19. I didn't experience "fake connections" when it is connected, it is so .
I cannot change the wifi channel, the same router is used by others. However it cannot be the cause of my issues since my notebook's network works fine on the same router.
Changing the radio... seems a good idea. It is my very first smart device, I even thought that this version number was for the hardware, not the software . I will find out how to do it, maybe give it a try. Hope it is an officially supported action .

Hi Lamsebamsen,
The TD2 sees 4 wifi networks, my notebook sees 8. Is it many or not? I think the 4 which the TD doesn't see is many .

I'm afraid not, as you would have to HardSPL your device first. There would still a way to get back to your original configuration but I don't know if you are prone to do so, that depends on how much responsability you can take on your device (is it from work or..). Another thing to try is to manually configurate your connection (e.g. assign D2 always the same IP, but watchout for network collisions!router should be set aswell)

[Q] Reboot router to connect to Wifi

I'm puzzled by the behavior of my phone. For probably a week at a time, I go to work, connect to a WIFI there, then come home, connect to a WIFI there. No problems at all.
Then it seems like after a week or so of 'being good' sometimes I'll wake up the phone and it will see the network, but will not connect to it, asks for passphrase repeatedly (WPA2-AES Cisco E3000 router) but just will not connect. I have found no way to trigger the phone to reconnect (and I refuse to do another hard reset because that is no solution at all).
The simple fix is to reboot the router. Presto, the phone will connect almost immediately.
I am willing to accept that maybe something is wrong with my router, although I have 3 laptops and a couple of IP cameras, and an Xbox that connect wirelessly all the time, and I never ever see this refusal to connect on any of those devices, and my wife's Blackberry will also connect whenever. So I'm thinking its my phone.
So for the experts out there, what is it about rebooting the router that fixes the problem?
I only recently learned how to get into the manufacturer's special app, so I'm going to pay attention to my IP address next time I have an issue, and see if it actually changes when I reboot after this problem occurs again.
Where does one discover how and what can be tweaked in the secret app? I'm cautious but not afraid....hey, I've edited the windows registry countless times on my PC and never toasted the OS yet! Does that count for something?
Add: I had this happen once at my work WIFI, using an ancient DLink router using WEP. At the time, I was trying out a bluetooth headset (Plantronics Backbeat), which worked, albeit, after I was done listening to the podcast, be darned if I didn't get into this refusal to connect thing, and unbeknownst to me, I was using the 3G data connection for what I thought was a wifi broadcast. That sucked 175 megs that day! I was a bit pissed about that. I have not used the Bluetooth since then.
Rebooting my router at work fixed the problem but I hate doing that, because I've got other equipment on that network that likes to be permanently connected.

the same happened to a frined of mine: interoperability issues with that model of router and the phone, changed the router and after everything worked perfectly, that sucks, but it is

Had a similar problem, and simply could not pinpoint the cause. Solution? I resetted my router to factory settings, and started to change all the settings from scratch to my desired settings. One thing that helped solve my problem was that I changed the default IP address used by the router (in my case, 192.168.0.1) as well as the IP range to something more ... random. Also, I limited the number of allowed IPs to 10 rather than the default 100...That helped. Never got a disconnect or problem connecting again. I had the same thing happen on my mother's iPhone and my brother's Galaxy S, and this solved it.

Maintaining a wifi connection

This question isn't too specific to the HD2 because my old phone, the Behold 2 running Android 1.6, did this too. I'm running a 2.2 TMOUS MyTouch4g ROM right now. The thing is that there is wifi at work with WEP 128 bit encryption, but when I connect to it, the connection lasts just a minute, just long enough for me to know it connects and open my browser before disconnecting, but it still says it's connected. It says it's connected right now, but I have no connection. The phone does fine on other networks and I work at an office of less then 15 people many of whom connect to the network on their laptops. I've never asked my coworkers if they connect via their phones, so maybe our network is actually secured against smartphone connections?
I'm not sure if this is the best place to ask this, but you all seem really smart

Evening Yallll - Wifi question for yas!!!

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.

Galaxy Note 3 Wifi Issues

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)
