Hey my xda friends out there!
Being a pretty new Nexus owner, I´m getting crazy by serious WiFi issues over here. My Nexus can´t get any stable Wifi connection at all...as soon as I´m making up a connection, I can be pretty sure that I will loose it after a few minutes. The only way out of this is...like I knew it from buggy roms before...to switch WiFi off and on again. After this procedure, I do have WiFi again, but it´s the same situation like before...after a few minutes --> bam, I´m out again.
Well, after some research on several forums out there, I can be sure that there are some other guys, struggling with same issues as well. Some of them are just having some standby issues, some of them can´t get any wifi connection at all. But an answer to my sort of issue? No way...
So what´s the deal here? I´m on a Stock Rom, what could be the reason for my WiFi issues? Any ideas?
Would be very very grateful for some support!!
Having the same problem here. YouTube seems to knock out Wi-Fi for me. Or marketplace downloads.

My initial suspicion is on a router configuration. Do you have this issue on multiple wireless networks, or just yours at home/work? Try somewhere like a coffee shop with an unsecured network. If you don't have the same issues on other networks, I'd look into messing with your wireless configuration. My router at home gives me issues losing connection to Google's servers (gray signal bars) intermittently, and I haven't yet found a solution.

Hey copkay! Thanks for your input!
The point is:
Dell Streak,
HD2,
SGSII,
Flyer,
Touchpad,
Transformer,
Galaxy Note,
Sensation.
ALL of them worked/are working well. So this has to be a Nexus thing, or am I wrong? Maybe its working better with an unsecured open WiFi Hotspot, but hey, this shouldn´t be the main place to work (imao!)
What do you think about it?

You have too many gadgets.
But yes, that's a good question. WiFi can be finicky with some drivers, so it's possible that yes, it's a problem with the Nexus in particular. The reason I'm asking is that it's much easier to narrow down the problem when you eliminate certain solutions. So does it work properly on other wireless networks? Does it do the same? Does it drop connection entirely, and if so, for how long? Or does it simply switch to gray bars?
I certainly don't recommend switching to no network security, but if it's a particular router/setting, more information would help to deduce the problem.
I had some of the same issues with my wifi (as well as sometimes it wouldn't fully connect and would get into an authenticating loop). I never had this on my past devices though. I don't know the ultimate solution to it, but I have found some work arounds for some of the networks I frequent.
What I've found is that I've had to turn off the auto detect wifi frequency band and leave only the 2.4ghz band while other times I've had to turn it back to auto detect.
While annoying and not the desired answer, hopefully it can help you out in the mean time.
I was out in the local mountains yesterday, trail riding with my boys. I was using My UN activated evo as a dedicated GPS unit. When we got back to the truck, I looked in horror at the empty holder on my bike, where the evo was when we started.
Now, the phone is unactivated, but I'm pretty sure both GPS and WiFi are on. To make matters worse, I had airplane mode on, so activating phone won't help. Now seeing how I turned both GPS and WiFi on after turning airplane mode on, is there any way to "ping" the WiFi? Time is of the essence, as I only have so much battery life. Thanks inn advance.
Wow...80 views, and no replies. A bit more info..first of all, yes,I did physically run the trail and look for the phone. Secondly, if I am able to get a signal off the phone's Wi-Fi, it would narrow my search area down to +/- 100' vs around 10 miles.
Since the Wi-Fi is not in active broadcast mode, one of the Wi-Fi sniffer apps would not work. The only idea I can come up with is using wife's phone, which I have tethered off before, and see if the evo tries to connect. Anyone have any others ideas? I'm open to any and all suggestions.

I was one of the 80 views but I haven't the slightest clue. I think due to that fact it is unactivated.
Call NCIS, they do everything in an hour on T.V.:silly:
Nah, really, I do not know.
I think by now your only hope is someone finds the phone and somehow connects it to you. By now the battery is probably dead. If you dont think so your only real option would be to bring another phone and try connecting to its hotspot every 100'. I think you may be SOL though.
Good afternoon XDA HOX owners,
I'm having a really strange problem with getting on to my wifi AT HOME ONLY.
The phone sees the wifi, registers the strength of the signal, but loses connection all the time. it's the first time I've had this issue with a gadget, and this is the 4th smart phone that's been owned in my household, while using this particular wireless router. there's also 2 laptops, a NAS and an iPad (EEWwwww ) ... and my mates that have my wifi password get on without an issue...
If I turn the wifi on the phone off and on, it works for maybe ten seconds to a minute, and then drops connectivity, but not the signal. I know this because of the little 'up and down' connectivity arrows that run in the CM10 wifi indicator. they go either up, or down or nothing, but the signal is still there.
Any help would be massively appreciated as it's ruining my love for the awesome device the HOX is, especially running CM10.
Thanks :good:
your auntie mable
Gonna bump this thread up because I'm home and it's driving me batty!

I had this issue with my homehub on the 'n' setting. Something just didnt work between the phone and hub. Try changing it to 'g' if its not that im at a loss. My.x would work everywhere else but home properly
Now works flawlessly
My nexus used to fly with the hub. Slightly irritated i had to lower performance purely for my phone. Its npt a massive difference but theres a reason theres a g and a n lol

Thanks mate.
So I've tried that and no luck. Virgin phone support says it must be a 'hardware issue with the phone'.
Any other thoughts?
Thanks

I'm having similar issues with my Wi-fi at home, tho my connection lasts longer, sometimes 10 mins, sometimes 5 hours+ sometimes all day. The strange part is that when i use wi-fi on the phone alot like some sort of heavy stuff youtube, downloading etc. then my connection drops. I've tried using only N connection and BGN Mixed on 20 and 40HZ channel and N seams to give me the best results, never tried B and G connections since i think those reduce the range of your WI-FI , too bad i didn't go for A B G N router. Anyway could be up to my router or something, every device that uses my WI-FI has same issues with this router. I even took it to the repair center they've done some ping tests and showen me that router works perfect. anyway back home still does those buggy things. If anyone has any good idea please feel free to suggest us.
I'm also having an issue with mine, although slightly different.
My phone connects to available wireless with no problem and stays connected however when I leave that location it stays connected instead of switching back to mobile data. I have to turn off wireless and then turn it back on to get it to switch to mobile data.
Kinda a pain in the arse and really annoying. I've missed allot of important emails since I got this phone due to me forgetting to turn wifi off everytime I leave somewhere with wifi.
None of my previous smart phones had this issue. I'm hoping that if I get custom rom on it, it will work properly,
hi friends this is my first post in GS3 world. We live in a rural area and are dependent on good WIFI service - I do tech work so the WIFI in the hacienda is very robust. All our other many devices love the WIFI rig: 2 ipad mins, one Galaxy Note 1, another older Galaxy, two laptops, one HTPC, etc. Only the new-to-me GS3 has issues with it. The visual indicator on the handset seems to not give an accurate picture, so we keep going into settings and seeing what is reported there... "Strong" signal is usually what displays, but in use, sending messages, making wifi calls, whatever, the results are pretty bad. We're using the stock messaging [google] app and stock T-Mobile WIFI calling app.
I want to say that web browsing is a little better, but can't really give details.
ROM etc:
android 4.1.2
baseband T999UVDMD5
Kernel 3.0.31-1128078
build JZ054K.T999UVDMD5
searching around the web I see a lot of the same complaints but really lousy diagnosis and lousier fixes [turn off 'data'; reboot the handset; call T-mobile... that sort of 'fix']
What is the scoop? Is there an internal WIFI antenna connection inside that needs to be checked?
Is there some elusive patch from Samsung?
Is the rig Channel-sensitive? [some older handsets only liked channel 11, or others only channel 6, etc.]
pls point me to the definitive thread if there is one...
thanks in advance
I'm not sure of any threads with much information on this. I don't recall seeing very many WiFi issues at all with the S3.
Are you rooted? Custom ROM?
If so you may want to try some of the other modems/baseband. Link in my Sig.
Otherwise, maybe try Odin flashing the UVDLJC or LJA firmware.
You say it's new to you, so I'm assuming you got it used. Do you know who you bought it from and did they report any problems?
How does it perform on other WiFi networks?

its all stock now.
are you saying to go ahead and nuke, reinstall stock ROM?
I don't have the option of going down Root66 - we are utterly dependent on WIFI Calling.
Is there a way to stop scanning selectively? that is, when I am on my own AP, there's no point in constantly scanning - there are other very weak wifi AP's in the vicinity and I"m wondering if somehow that causes an issue? my Note 1 is rock-solid. I don't recall a single drop with it in the 6 months I've had it. Most disconcerting is when WIFI calling drops - I've been using T-mobile devices for years and only once did I have one for which WIFI calling would disconnect, restart, and reappear like this. It will drop out, then refind its WIFI connection, then you get the "WIFI is Ready" all over again, just like you do when Rebooting the phone.

Yes, nuke everything. That's the only way we can rule out modified/mismatched firmware as a cause.
root66 is stock firmware with root injected into the system image. So wifi calling will still be there. It's just whether or not you want root.
Also wipe data/factory reset. If using stock recovery, this WILL wipe your internal SD. Backup your user apps with TiBu/RTB, and your internal SD card. Do not backup system apps.
You can adjust scanning frequency with build.prop modifications, but I personally use Tasker to control when it's on and off.
ahh. my fault.
ok, we'll get on it tonight and report back when squeaky clean.

Friends, I successfully nuked the GS3, flashed with Root66, got everything working really well but the WIFI issues resurfaced.
Does the GS3 just have a really weak radio?
Compared to even the most humble Galaxy S4G [old and tired], its WIFI performance is not impressive.
Compared to my personal Galaxy Note 1 running more/less stock ICS, its awful ... annoying, unreliable, glitch.
WHY?
My suspicion is that it has trouble switching/credentialing/authenticating from one physical router/AP to another. In our wifi lan setup we have a common AP composed of 2 routers of different chipsets/mftr. Works dandy on ipads, iphones, windows 8, windows 8.1, my Note 1, older/retired/sold androids, etc. The Galaxy S3 is pretty much alone at having trouble when the physical signal of one gets weak and the second one is available - it seems to fumble the ball. Thus, you try to make/receive/talk wifi Call, and get random drops, retries, reload of the WIFI Calling APP.
is there a fix?
Set static channel?
Set static IP [instead of DHCP/select] ?
Grab inSSIDer from the play store, it'll show you if you are on the best wifi channel for your network.
Try turning off some of your other devices wifi connections. May be that the router isn't handling them all at once very well.
Do you have anything that operates on the Wireless-G standard? If so shut it down. Itll only severely degrade the entire networks performance.
You need to be rooted for this, but try the LJC and LJA modems, others too if your up for it.
Does it exhibit the same problems on other wifi networks?

Thank you for helping!
OK - Let me ask a question [it is rooted - root66 per above, busybox, SU, etc]:
I've used InSSIDer before and moved channels here and there and what I noticed is that the way inSSIDer deals with signal data display, whatever channel you pick, it will show one of the other channels as being "better". switch to that channel, and it will show some other channels to be better, etc round and round we go. maybe I'm not using it right...
as to G-only devices I'll give that a shot - I think one of my windows units may be all G. easy fix.
To me it seems clear: the places where the GS3 goes ambiguous and fails to maintain a connection is where the two AP signals [again, one AP,one login, one authentication type, but 2 physical] are pretty evenly matched, per how WIFI Analyzer displays the data. If I shut off the tertiary router, it will just drop signal when you move a tad too far away which is what one would expect, but the GS3's "reach" is the worst of the lot. I'm hoping somebody has figured out how to get hold of that radio and boost the signal.
I don't have a feel for how it does otherwise - we are dependent on WIFI calling at home/office - when out and about its the usual drill... sit in the right spot at the restaurant and you're good.
Those modems you suggest: do they support T-mo WIFI calling APP ?

As or inssider, or any similar app, I don't go by what it says is the best channel. I simply look for the channel that has the fewest networks overlapping it. It probably tells you a different one us best each time because its taking into account that there is now another network on the previously recommended channel, yours.
If you have a single G device on an N network, it'll slow the entire network down to wireless-g speeds. So yeah, shut down that machine and ill bet you see improvements across the board. (You may need to reboot the network and other devices)
If you have one router and one AP but both with the same ssid and pw that may be causing your problems. With this type setup there's no way to really be sure which you're connected to. You may connect when close to one, but when you move away from it and closer to the second, it won't connect to the closer/stronger one automatically. Even if you turn it off then on again, it may still connect to the first if the signal is strong enough, even though there may be a stronger one available.
Try having it connect to the ap using different credentials and then you should have greater control over which you're using at a given time.
Allthe modems should function properly with everything they are supposed to, so yes they'll all work for wifi calling. I was looking into a way to adjust the Tx power for wifi a long time ago. Ill see if I can find what I was doing and try again. If you use a 3rd party router firmware (dd-wrt or tomato), you can adjust Tx power on the router itself if I remember correctly.

in reverse order:
- as to to the wifi device power/range I was speaking of the phone/handset, not the router. But since you mentioned: I have not found an N or beyond router that has GOOD open source; open-wrt, dd-wrt, tomato et al - if you really read carefully what the feedback is, a lot of them suffer bad speed degradation. the old wrt54gl's would run full-tilt G speeds, over a wide range, and last for many years, but I have not found the equivalent in any other device running or capable of running one of the good [or formerly good] open-source codebase
- Are you sure about that client-bridging common-ssid/pw/encryption? the whole point of such firmware is to make the transition seamless and it is for every device except the GS3: two ipad's, one Galaxy S4G [999v], one Galaxy note T879 [debloated stock ics], two HP workstations, three laptops - gateway, thinkpad, hp Envy - not one of those devices gags when switching router signals. only the GS3. with the other devices, you literally forget that you've got multiple routers
The GS3 code has multiple network notifications also that the other two Galaxy's do not: it interrupts your blasted work to INFORM you that you're signal is dropping [how dumb is that?] - then it informs you that you've been disconnected, and informs you that you're "not registered on the network", then it informs you that it is logging in again, then it informs you that WIFI Calling App is ready for use as though it was the first time you used it.
- I will give the modems a whirl. I'll stash a full nandroid and try them out - If any of you happen to have a link to the 'how to' steps pls pass on as it will save me a lot of careful reading.
oh, and I was wrong about G-device; i replaced that one with an N device. Frankly, G speed is way fast enough. my internet connection is only 20Mbps so if I had the old WRT rigs back and up/running it would be PLENTY fast. Mixing B with G... now that was a real problem - there you were talking about effectively 1 to 5 Mbps

I havent used any 3rd party firmwares for my networks in a long time. I was assuming that for the Wireless-N routers, they would have come a long way and solved a lot of their issues by now. My mistake.
I am sure about the router/ap setup. (Is your second set up as an Access Point or Repeater? Either way the same issues can still present themselves) I refer you to the following website for information on this and a little bit to back up my claim. It may be worded better or easier to understand than me, but either way its good info.
http://www.smallnetbuilder.com/wire...w-to-add-an-access-point-to-a-wireless-router
Step 3 is where this is touched on.
I have to be honest that I am skeptical that your other devices are transitioning over to the AP. (im guessing they are ALWAYS connecting to the AP) Unless their radios are actually much weaker than the GS3's. In fact, what I suspect at this point is that your GS3 is trying to connect directly to your router all the time, while your other devices are connecting to one or the other, all of the time. This is one of the draw backs to using the same SSID, it is difficult to tell which you are actually connecting to.
Read over that linked page. Let me know what you think.
Will do. thanks for that.
if your theory is right, on any one of the frequent auto-disconnect cycles, you're saying that the GS3 will connect to which? the stronger one? any idea how the firmware is setup to pick a winner?
Also, webbing around for answers [there are a LOT of threads on this issue as it turns out], there's a good deal of discussion about 5ghz vs 2.4ghz bands, and that samsung/t-mo have changed how the firmware handles transitions [or connect/disconnect] to one or the other. i.e. https://support.t-mobile.com/thread/37707?start=0&tstart=0
I can set my routers to one or the other if that would help - Any ideas if one is preferable?
Ever heard of GS3 being "channel sensitive"? I have not. Early WIFI/WIFI-Calling capable models from several mftrs were quite channel-nitpicky.
I could easily check that transition [seamless dropping of one, connecting to another] if there was a way to verify the MAC of the connected ap. know of such? I can't find much in the way of advanced settings but I have not a guide to the keyboard/manual settings methods for this build 4.1.2.
read the article but see no discussion of your point.
pick the right link?
the setup I'm using is simple wireless bridging - no physical medium between the twain. subordinate router has the mac address, encryption type, ssid, credentials and channel setting of the boss. reboot and done.
pretty much the same type of bridging as with DD-WRT [though it has a lot more options... more confusing]
I really think that the GS3 modems aren't that good, especially when it comes to wifi calling. My family and I haven been having some bad signal problems as of late so we've been relying on wifi calling to make calls. I had a lot of dropped calls in the past but I knew that had a lot to do with the old modem/router setup I was using. I would lose internet connection not matter what I was on. The internet would just drop and then reconnect, very frustrating if you were on a call or playing Xbox live. so last week I hooked up a new Comcast modem with wifi. The drops stopped but I still have to literally be standing right next to the modem if I wanted to make sure I didn't lose a call. If I walked into the kitchen, which is 15ft away, I'd get the little beep that warns that I'm about to lose the wifi signal. I know my signal that's coming from the router is good because all my devices, including the phone says so. Hell, the kids across the street asked if they could have the password because their internet was shut off and my signal is strong over there.
I don't have anything technical to support what I say, just experience but that experience tells me that Tmobile's wifi calling doesn't work that well unless your within 3 ft of the router.

Also, webbing around for answers [there are a LOT of threads on this issue as it turns out], there's a good deal of discussion about 5ghz vs 2.4ghz bands, and that samsung/t-mo have changed how the firmware handles transitions [or connect/disconnect] to one or the other. i.e. https://support.t-mobile.com/thread/37707?start=0&tstart=0
I can set my routers to one or the other if that would help - Any ideas if one is preferable?
Ever heard of GS3 being "channel sensitive"? I have not. Early WIFI/WIFI-Calling capable models from several mftrs were quite channel-nitpicky.
I could easily check that transition [seamless dropping of one, connecting to another] if there was a way to verify the MAC of the connected ap. know of such? I can't find much in the way of advanced settings but I have not a guide to the keyboard/manual settings methods for this build 4.1.2.

Accorfong to my research it'll try to always connect to the first one it connected to. Even if the signal is stronger on another. That's the main point I was linking to that article for.
As for which band to choose, 2.4 is usually best. 5.0 is faster, but with a shorter range and more susceptible to interference.
tmob removed the option as you can manually select which you prefer. There is an apl I include with all my roms though that'll give this option back. Let me know if you want the link, though I doubt it'll help ypur particular problem.

read the article but see no discussion of your point.
pick the right link?
the setup I'm using is simple wireless bridging - no physical medium between the twain. subordinate router has the mac address, encryption type, ssid, credentials and channel setting of the boss. reboot and done.
pretty much the same type of bridging as with DD-WRT [though it has a lot more options... more confusing]

Ok, so its more of a repeater setup. The routers are not connected to each other via Ethernet or powerline?
Step 3 of that article is what I wanted you to read. Its on the 2nd page. (Though I do suggest reading the whole of both pages)

I really think that the GS3 modems aren't that good, especially when it comes to wifi calling. My family and I haven been having some bad signal problems as of late so we've been relying on wifi calling to make calls. I had a lot of dropped calls in the past but I knew that had a lot to do with the old modem/router setup I was using. I would lose internet connection not matter what I was on. The internet would just drop and then reconnect, very frustrating if you were on a call or playing Xbox live. so last week I hooked up a new Comcast modem with wifi. The drops stopped but I still have to literally be standing right next to the modem if I wanted to make sure I didn't lose a call. If I walked into the kitchen, which is 15ft away, I'd get the little beep that warns that I'm about to lose the wifi signal. I know my signal that's coming from the router is good because all my devices, including the phone says so. Hell, the kids across the street asked if they could have the password because their internet was shut off and my signal is strong over there.
I don't have anything technical to support what I say, just experience but that experience tells me that Tmobile's wifi calling doesn't work that well unless your within 3 ft of the router.

Make sure you don't have a bottleneck somewhere on your network. (Such as a misconfigured router, a docsis 1.0 cable modem, etc.) Or as I stated before, if you have a wireless g device active on your network, it'll force the whole network to degrade to wireless g speeds. Also use inssider to check if you are on the best channel. And check for any points of interference. (Microwaves, cordless phones, power hungry appliances, etc)
If your cell signal went south recently, it may be due to the work tmobile has been doing. What worked best before, may not anymore. Try out the many other available modems to see if it improves.

Thos is a copy/paste of the text I was referring to.
(Starting under step 3)
But most wireless clients are very "sticky" and tend to stay associated to the first AP they encounter,*even when APs with stronger signals are available. So I recommend setting a*different SSID*for the AP, so that you can manually control connection.The other advantage of setting a different SSID for the AP is that you'll be able to see both the AP and your main wireless router if you're using the Wireless Zero Configuration utility that is built into Windows. Even in Vista, Microsoft has stubbornly chosen to not show multiple wireless networks that use the same Network Name / SSID.
4) Set the AP channel
One large network practice that you*do*want to follow is to set the AP to a different channel than the main wireless router. In the U.S. you should use only the non-overlapping channels*1, 6 and 11. So if your main wireless router is set to channel 6, set the AP to either 1 or 11.You should probably do a quick site-survey first (see this HowTo), to make sure that you aren't setting the AP channel to one used by a neighbor's network. If you can't find a completely clear channel, choose the*weakest*neighboring network and set the AP to its channel.

I'll look into it.

Hi @ all,
So i have been using my Note 2014 for around 3 weeks now.
Despite the lags on the device while browsing or searching in the playstore , i noticed or lets say - i get frustrated that webpages dont load. I have to refresh them several times to finally show up. The same with theplay store and any other app that requires a internet connection.
So what i want to know is, if you guys have experienced the same or if everything works good for you ?
Thanks so far...
Bottom line is that if there would be another tablet (windows or android ) with a good pen like the note has, i would have switched devices immediately i guess. For college the spen is superior than any other pen i had a look at so far. Despite that it is still a good device..
I haven't had any Wi-Fi or BT issues. I compared download speeds between my N3 and N10.1-14 using a 1GB test file and the N10.1-14 was significantly faster using the same router. There are a couple of wireless "issues" threads that point to some N10.1-14s having possible h/w issues. If you're having connection issues across multiple different routers and networks you may have a h/w problem.

I have a similar issue. While websites seem to load normally in the browser, I frequently get connection errors or time outs. For example in the Play Store it has happened several times that, after clicking on an app, the page for that app can't be loaded and al I see is a 'reload' button in the middle of the page. Clicking that loads the page quickly and I never actually disconnect from my wifi. I have also had to re initiate several app downloads as the initial download created an error. This happened mostly (if not exclusively) when I send the app through chrome on my laptop. At least one other app also has some connection issues sometimes after it gets a push notification that triggers the app to update.
I feel like the issue is when the tablet tries to send data right after or while it's receiving data.

Thats really weird. If i dont find a solution for this i will trade it in. Im currently keeping it only for the great spen feature. There is currently way too less competition for tablets with a good working active stylus (only wacom technology atm)
Similar issue here, but maybe not to the same extent as yours.
For me the most prevalent apps that have this issue is the play store and youtube. I will frequently get connection error/server error on those apps. The funny thing is I can open browser in a pen window and load any site just fine while this happens, it's the apps that refuse to load pages. So I believe my internet is fine, it's an issue with the apps. I'm gonna try factory resetting later.
Here's the Wi-Fi performance of my N10.1-14 (on the right) and N3 compared. They are connected to the same network, were tested in the same location, and tested within minutes of each other. On average, the N10.1-14 actually outperforms the N3 in signal strength. If you notice in the elapsed time chart there aren't any major dips in the connection speed which there would be if there were a signal or h/w problem.

Mind giving me the name of the app or how you ran the test ?
I just downloaded a normal download speed app. The result was really odd. While my nexus showed a speed of around 3 mbs (wtf?!!) , my note showed a speed of around 25mbs. But if i open websites or browse youtube or whatever , my nexus is always way faster...

Thanks. I dont understand it :
I ran the app.
Nexus 4 : 12mbps
Note 2014 : 121 mbps
They both use the same wifi. But still the whole internet perfomance is way slower than on the nexus .
Thanks for your answers. When the storm is gone i will go to the store and trade it in...

I am one of the guys here which didn't have any lags (And I am known to fast devices). Also with the stock browser and play store I have no issues. Everything is fast... so it must be something else which interfere here.
PS. I made a test together with my HTC one and when the Note was faster by loading pages.
