Hey man, can I use your wifi?

I finally tossed my old wifi router and got a shiny "new" Linksys E2000 and have it set up pretty much as stock. B/G/N, a few ports open, WPA2 Personal security, etc. Nothing special except that, of course, the Focus won't connect to it. I had to ask a neighbor if I could use his wifi so it would stop whining about email. How many more months until this "phone" can do something useful? Tell you what, how about if I mail a piece of it to Microsoft every month they don't have an update for it and attached to each mangled piece I attach a note that reads "You"? Think they'd get the point then instead of combing their hair around it? I'd just sell it on ebay except what do you get for a Focus these days? $30 if you throw in the sim card? Still might be worth not having to look at the thing every day, tho. Never again, Microsoft. WP7 is as dead a WM....well, no, I can connect my Fuze to the damn wifi.

Linksys routers, especially the new E series, are notoriously buggy. My Focus connects to two of my 11n routers just fine (one TrendNet, one NetGear). So, it looks like it is the problem with your shiny new router.

I concur. I've connected my Focus to dozens of hotspots without issue.
On the other hand, I've had problems and complaints about 100% of Linksys routers that are owned by clients (granted, they call me when they have problems) and two Linksys routers that I managed myself.
I would never recommend Linksys, and will never own another. I have and will recommend the Samsung Focus, however, and will own another Windows Phone.
(For the record, I own a Buffalo router running http://www.dd-wrt.com)

Ever since Cisco takes over Linksys, its Linksys brand getting worse and worse. Not only the initial release firmwares are always buggy, Cisco also deliberately remove features that are common on other brands of consumer routers so that it does not eat into its Cisco commerical grade router business. Most common compliants I read is that WOL packets do not work on Linksys routers and switches after a device entering sleep for a while.

I have a Linksys E2000 and mine works great. I was loyal to the D-Link brand, but their recent routers have had too much trouble. I was resetting my router at least once a week.
I will admit, it seems to be hit or miss with any brand of router. Just go to Newegg.com and you'll see hundreds of reviews both positive and negative for any brand router. Why can't they just make something that works?

I kind of doubt that. Every other device I own works just fine. Bridges, iPhone, iPad, Galaxy Tab, 3 laptops, 2 netbooks, other people's equipment....everything that anyone has tried to connect does so and very quickly. Just like at work where there are literally dozens and dozens of devices connected and what won't connect? Why the Focus, of course! Actually, the E2000 is an excellent router and it gets very good reviews nor have I ever had a problem with a Linksys in a whole lot of years of using them. No, I tend to think the Focus is the junk here.

I am sorry my friend but it is not the Focus phone in "general" You must have a faulty device and should take it back to the store to return it or get fixed. There are so few complaints about Focus devices connecting to routers. I have never had a single problem and I have connected to dozens of routers all of different brands and models.
I would definitely take the focus back to the store, if you bought it from an ATT store, at least I hope you did and didnt get it from some other source as you are probably screwed.
I have been so pleased with my Focus, granted all of the setbacks with updates and short comings.

OP:
I have found people with issues connecting their Android & iOS devices to this router as well. The Android post I read suggested using WPA2 (AES) on the router. A iOS person suggested taking wireless settings off auto and actually selecting a channel such as 11 as well as selecting B & G or G & N instead of auto to fix connection issues.
My personal experience with Cisco Linksys routers in the past has been mixed mode can be flaky. When I set the router to G only or N only (use only if all your devices support N) everything runs smoothly.

yup it must be the router, back home my Focus failed to lock onto my Linksys WAG200 gateway if my Laptop was already connected to it. So I had to turn off the wifi on my laptop and let Focus connect to it first and then let my Laptop also connect. Strange

[Q] Wifi and me - not happening! Piece of CRAP google!

I'm sure I'm not alone in this.
My N4 won't connect to wifi. Well it connects but Won't keep a connection to complete a playstore app install nor update the system itself?
This is what I posted on "Issue 40065: Nexus 4 and Nexus 7 Wifi Drops connection Android 4.2"
New device just received. Will connect to wifi but unable to install any apps thru play store.... Just shows data transferring but none actually happens. I'm unable to install none of the gapps updates. Left it alone for 2 days did not help. removing password from router and making it an open router did not help. Now trying to decide I should return the device as it is only usable as a phone not a multimedia device which this N4 should be?
There are a lot of people having the same kind of issue on this phone. A little search brings up lots and lots of complaints.
Still unable to connect to my router encore model 2AN3.
Tried to connect to open wifi router at McD and [email protected]#$ - still no go. It will connect think about it and stops. The icon at the top turns green and gray and keeps doing it.
How ever I was able to connect to the open wifi router on another Nexus S (my older phone) and was able to download updates and install said applications from play store.
This tells me that hardware is good. Software coded so badly that it is unable to keep a connection to routers.
So if you need to use this phone on a wifi router - wait until google fix this or get another phone.
As for me - it is a shame I will have to return this phone to google as it is useless media device. Just a phone which I can get a cheap phone for 10 bucks not $400 piece of [email protected]#$%T.
Sorry for the RANT.

Also flashed rom CM10.1 stable and xylon 17 stable. Still same problem repeated. both ROMS can connect to my hotspot on my NS but unable to neither my home router nor public wifi.
A few things I have tried.
1. avoid poor wifi disabled.
2. switch chennels to 6 or 8 - tried all.
3. Resetting routers
4. Assigning static IP address
5. Cleared cache from recovery
6. changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
7. Flashed new kernel Running franko.
8. Flashed 2 other ROMS/cm10.1 and xylon17 both stable versions.
My home router have not trouble connecting to all other devices at home (NS, HP touchpad, 3 desktop and 3 other laptops, Tried with N4 being the only device that was turned on. : still no go!! WHY WHY WHY WHY WHY!!!
Also followed the directions from this thread. Still no candy.
Please take a poll and let post here if you should find a good solution.

Mine works flawlessly. You should contact Google for a RMA.

I guess its the lease period on your router that you need to change... put it to lease expiring n a day or two... shuld work.. I had this issue when I upgraded to 2.3.6 on my Atrix

I just called. This guy treated me like I'm noob. But I digress.. He asked me to turn off GPS and try again saying that GPS and wifi together can not be on at the same time. That still did not work. So there is a request for replacement. Not really sure when I will get it. But keep my finger crossed - that I get a working wifi and gps at the same time ??
Don't really want to return it though since I like the phone form factor and such!
What a shame.

Why wouldn't WiFi and GPS work together? I don't see any reason as to why one would interfiere with another

You shouldn't be flashing ROMs to try and fix something as basic as this. You're only adding more variables to the problem. My WiFi has been rock solid, and so apparently is that of most other posters. This would tend to indicate that there is a specific problem with your phone.
Unless there is something seriously wrong with your router it's RMA time I reckon.

Just to re-iterate .....
Wifi works if I connect to my other nexus S's hot spot.
Wifi will not stay connected to allow me to go to play store on any wifi router (home Encore ENHWI-2AN3 firmware version 1.1.3 - Mcdee's open wifi and [email protected]#'s open wifi router.) It will connect - get a blue wifi icon with a few arrows ..... but will go to gray and back to blue and so on ....

[Q] Same but different WiFi issue plus...

Hey guys. This is my first post here. Checked all the troubleshooting threads and did not see this. Have seen the issue similar on other forums and sections, but my situation is a little different.
I have a rooted 16GB S4. I have been using the same wifi connection since August 2nd. The wifi on my phone, computer, TV, and Xbox have all been working this whole time. This afternoon I tried to check something on my computer and had no internet connection, but was using my phone. Thought the issue was my computer. Left. Came home. Computer is connected fine. My phone, my wife's iPhone 4s, TV, and Xbox will not connect to the network at all. So this situation is a bit different as I have been connected for 3 weeks and now wont work. I assume its not my phone because so many other devices dont work either. Not to mention it's both IOS and Android. Anybody have any ideas? Thanks a lot.
My plus is just something small. Yesterday my lock screen blanked out. I have my other lock screen pages, but my page with the date and time and all just randomly went blank and will not come back after reset.

If I read everything correctly then you don't have an issue with any of your devices. Chances are it's your wireless router. I would recommend replacing it to see if that fixes the issue. You can always buy one from Best Buy and take it back if that doesn't fix your issue.
EDIT: Forgot to mention that it may be the way your router is configured. (I doubt it's your ISP if something is working but other stuff isn't.) What kind of router do you have?

I think its a netgear. We are living in a downstairs apartment. All my devices now work. It was weird. First nothing was on. Then just the cimputer. We went to sleep and woke up and phones were working but not tv or xbox or computer. Now everything is fine again.... I did send an email to my landlord and ask her to unplug the router for about 30 seconds. She may have done that....

I definitely think it's the router. Netgear isn't the best around, and I have found that they do have problems from time to time. If you had access to the router yourself that would be the best way to troubleshoot the issues.

If things were working fine for some time then just started acting wonky, it wasn't anything your devices (S4, iPhone, computer or xbox) could've done, per se. Something had to have changed with the router - not that it's going bad or that it sucks, but something was altered. The smallest changes in networking can make the biggest difference. Don't just buy new devices and throw out the old when an issue arrives.
That's great its working now. For future reference, you should get your own in-apartment WiFi, like "Clear", cheap and works well in most areas, this would narrow down your possibilities of your internet not working properly on your S4 and other devices.

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.

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)
