Hoping someone has a solution. My wifi keeps disconnecting/reconnecting. I'm running TNT 3.1.1. Also the signal is really low even though I'm next to the router. I've searched around, but can't seem to find an answer.
Thanks.
Right there with you on this one. I can't get more then 10 feet from my router before I lose my connection. Very annoying to say the least. I wonder if this is software or hardware.
I have the same and I am using vegan b3. I don't recall having this issue while using tnt 2.2. Or the stock. Anyways, I have noticed that it only happens when I am on a page more than a few mins such as reading an article, etc. If I am watching movie(flash) or playing online game, it is fine. I am suspecting it has something to do with the battery management.
I'm running stock 3389 with GApps.
I get full signal when I'm by my router and around my apt. I have a Linksys WRT610N with DDWRT firmware. It's running on a 2.4Ghz full N radio. I used a wifi app called Wifi Analyzer on my phone to find the best channel to set the router to, as in apts. you know many people are using the same channel and this can lead to signal loss on your devices.
Anyway, it sounds like you just need to find a less crowded channel maybe, I don't THINK it's the device. Are you using G or N or both? When I was using the router's 2.4Ghz in G/N mode I saw a slight signal drop throughout the place which is essentially why I switched to pure N and then just set up a legacy network on another router for wifi G stuff.
I had this problem not with my non-existant G tablet, but my latop, cell and other wifi connecting devices.
I changed the chane l# my wifi was broadcasting on and it fixed it. Maybe you guys can try that.
In my case, it is not a signal issue since I always have full bar and there is not many wifi hotspots around my house. I am used to it now and when I see the wifi icon is gone, I just click the location of the wifi icon, and within a sec or two, the wifi icon will appear. I will flash to tnt. 3.1 soon, hopefully the problem will,disappear.

I havent used VegaN - is there any setting that could possibly be turning off wifi when the system is idling? In phones there's a wifi setting that turns it off after a certain time idle. I know it's unlikely but just checking all the bases.
Yea +1 on this problem

This appears to be the case. If so, it completely ignores my WiFi Sleep Policy, which I have set at "Never".
I have the problem whether stock ROM or not. Love the tablet, but this is frustrating.
My experience is that the device is finicky with some routers. I actually have two to test with, and early on one would work fine and the other would fail constantly.
Some suggestions, for testing:
- Change the channel (already suggested)
- Turn off all security to see if that works better (again, just for testing)
- If it's an N Router, change it to G only.
if one of these changes "fixes" it, at least you know what direction to look in.

It's also very sensitive to interference I think. My neighbors have dozens of APs on every Inglewood channel available, and the tablet gets thoroughly confused. It seems to like G a lot better than N in this situation (makes sense, N in general is more interference prone than b/g). In another place with only a single high power B/G/N router visible at all (nice thick concrete walled building), it's only done the disconnect/reconnect loop to me once in several days.
Time to do some disassembling and see if there's room for a better antenna, but I'm not prepared to rule out a broken driver just yet. Especially with all the other sleep/suspend problems we have. Or break out the buckets of RF blocking paint...
Thanks Roebeet. I tried a couple things. Assigned a static IP to the tablet which seems to have stabilized the signal, it doesn't drop out as much, but reception was still only 1-2 bars.
Just for the sake of it, I also reset the router back to factory default to see what would happen. Funny enough, the signal reception on the tablet improved from 1-2 bars to 3-4 bars, but once I re-entered my settings it fell back.
I still can't connect if SSID is hidden. I'm using a Dlink DGL 4300.
What routers are you guys using? Especially if you can get it to connect to a hidden SSID.
I had this problem too, signal was always fine though. After coming out of idle i would notice the WiFi is off. checking it in settings could watch it turn on start searching and then in three seconds the WiFi would turn off and then on and searching again, and continue the cycle. Not sure what is causing that, but in the WiFi setting i set the WiFi to never turn off, even if the device is sleeping and Ive never had the problem yet.
This just started with mine too (running 3389 and Enhancement Pack). I went to my router and switched channels and switched to 802.11 G Only, and it's up and running again. Strange that it worked really well for the first 12 hours or so with no changes to my router. Let's hope it doesn't happen again.

I have the same problems. The only way I worked around it was by turning airplane mode off then either turning off my router or moving away from any wifi signal. Might try changing the channel... when my internet comes back on(adhoc tethering atm)
Looks like its my router. I took tablet to a friends house and it gets a strong reception.
I know it sounds weired but try to clean Market application's cache.
It works in my case. Or (if it is some kind of memory issue) cache for all other apps.
I have noticed that it is not that bad of a problem and have heard that it is a "feature" of the gtab, if anyone can elaborate on this? There has got to be a driver/kernal that can override and keep the wifi on. Any older gtab users every remember this as a problem? If so, what did you do about it?
In my case, have had gtab for about a week. Using factory settings initially, everything seemed to work fine. Then it started randomly dropping wifi.
couldn't figure if it was hardware or software. Talked to customer service.
Restored tablet to factory specs--worked fine. Started loading on some extras, checking wifi after each load. Bingo--when I loaded Adobe flash player, wifi started kicking off.
Have tried it with several versions (10.2, 10.4)--same results. Not sure what to try next.
Hey guys,
tried to search if any other problems like this exist...
My WiFi seems to be disconnecting often... Meaning it still shows as connected, but it wont load internet pages or download anything / stop at some time downloading.
Now i tried to look at my WiFi with WiFi analyzer... at it seems that I am on the best channel for my area... but still... I also tried 5Ghz and 2.4Ghz same results it seems...
I am not happy with it... it seems so unstable, that even at home often i use 3G just because it doesn't crash that much... if the WiFi works i get great speeds though... but it seems like a hit and miss....
any idea?
You may ha e.faulty connectors as that is the problem w some of the one xs also go to WiFi settings switch it from auto to 2.5 GHz idk if 5ghz works well or not

Suspect an issue on the router's end...
I have the same frikken problem. Drives me crazy. Ill be rolling thru XDA or whatever, and suddenly my phone disconnects wifi and switches back to 3G. Then maybe a second later reconnect to wifi. I have no explanation for it. I have an HTC rep calling me today. Ill let you know what he says, but I wouldn't hold your breath LOL. I know man it sucks.

Make sure your routers firmware is up to date
I have theexact same problem. Let me know if you find a fix, I'm on the verge of returning it.
Actually it didn't seem to be so persistent, anymore.... And I did update the firmware of the router.... If that really helped.... I do t know....?

I just updated the firmware on my router as well. Well check back after a couple days but so far so good
Wi-Fi not the greatest for me either. Running a WRT54GL which is one of the most rock solid routers ever with Tomato never have issues with it on my 3D or any other devices. Having similar issues you are having. Sometimes just not staying connected even though it shows connected. Other times no wi-fi on when I wake the phone. I'm guessing it's bugs other people have reported similar problems. Going to see how it performs after the next OTA update I'm hoping they fix some stuff. Also I hope they fix the very annoying set time zone message. Not sure what caues that but you are certainly not alone with the wi-fi issues.
I currently have mine set to 2.4Ghz only not auto since I don't use N for my phone there is no need for it and it sucks more battery at least it did on my 3D.
I would just hang tight and see what the next OTA brings.
This is disturbing. There seems to be a great deal of variation in build quality (i.e. Wifi issues, screen light bleed, data issues, etc.). I have had none of these issues with my phone. However, multitasking is a joke, and google wallet is broken after working previously. My phone is none stock at this point.

I added a post to another thread - in my case, I found a definite correlation between wifi drop and phone temperature.

Posting it here as well in case someone remembers how hot their phone was when their wifi drops..
Just throwing in my experience for the record...
I'm a network administrator for a living so I know a few things about making wifi work. In a nutshell my Evo LTE will not maintain a stable conneciton to *any* wifi N network under any settings. I've tried mutiple routers and multiple ROMs for my phone and none would work properly. I'll spare you the details but channels, encryption, spectrum, root, preamble... nothing would work on N.
WiFi G = rock solid
WiFi N = sucks more than Paris Hilton
Since I concluded that G works perfectly I've just made sure to stick with G networks. Not worth fighting Sprint for a new phone that may very well do the same thing for me. :victory:
Not sure if you guys are having the same issue I've been experiencing, but my wifi issues have went away since using Mozilla firefox. I messed with my router settings, used 2.4 ghz, 5ghz, wifi n, wifi g, different security configurations, a bunch of different wifi apps, just about every browser on the market and as odd as it sounds, only Mozilla has solved my problem. If I use any other browser, I get hang-ups and phone gives me the impression that wifi isn't working. I don't know why or how mozilla works great while all other browsers' performance is inconsistent and frustrating but its a fact. I strongly recommend anyone with "wifi problems" give mozilla a try.
has anyone found a solution to this wifi issue?
i can connect to my home router with no problem, very stable. but outdoors, on cablewifi, or optimumwifi the connection is terrible. the signal shows connected, but there is no data being uploaded or downloaded. i think it might have something to do with channel congestion, but my friends iphone has no issues whatsoever.
so whats the deal with the evo's wifi radio???
I just noticed that my wifi gets very slow after 12am I'm on MeanROM 1.6 anyone else's doin this
If your WIFI is slow you may want to check with your ISP.
There is no reason that a ROM would cause YOUR internet connection to slow down.
Especially after some specific time.
Im guessing you have a PC somewhere in your home network behind your wireless router/access point, yes?
Next time you are experiencing these slow downs with your phone, jump on the PC and goto www.speedtest.net and check your bandwith.
Myguess would be the problem is there and NOT with your ROM.

Have you tested this out on different access points or with different ROMs? I would first try a different access point at around the same time. Go to a friends house with WiFi and see if you have the same issue there. If you don't then it may be your wireless access point configuration.
Another thing to try, download WiFi analyzer from the Play Store and check your signal strength and see if it dips around midnight and another signal interferes with your signal.
Lots of variables here.
Hey guys, lately my wi-fi connection has been very slippery, as if it drops and then reconnects often, although it remains physically connected to my router. I don't know if it could be my router since every other device in my home is connecting to it fine. My phone is able to connect well to networks outside of my home, though, so I am unsure. Do you guys think it's the routers fault or maybe a kernel issue of some sort (I'm running stock kernel)? I've been having this issue on Tranquility and Viper ROM (maybe also on Mean) so it can't be A ROM issue. Any help would be appreciated. Thanks!
sounds like u have a gaf phone man.. if every other phone in ya house connects fine.. its not the stock kernel.. also the update we just had the OTA was supposed to fix wifi issues.. so u mite have something up with your phone.. alot of people had wifi issues that why they had a fix in the for it in the OTA we just got... my phone did the same ishh before the OTA now its fine..
I drop 3G like It's cool but that's sprints problem, never had that issue on WiFi. This phone has very powerful radios.

Check your wifi settings and make sure that your wifi connection is set to never sleep. Also Check your wifi frequency band in "wifi advance settings" and make sure its set to 2.4 only. That might help.

There's an app in the Market called WiFi analyzer. U can use it to see what other wireless networks are operating in your area. It will also reccomend the best channel for your router to be on.
Sometimes there is a lot of interference on your channel and switching it will help or has helped quite a few people with your problem that I know of.
I had a problem at work with a linksys router not issuing an ip address to my phone consistently. What I did is take a screenshot of my ip address, subnet mask, DNS address defaults, etc. when u could connect. Then I made myself a static ip using that info. A good app that basically let's u run ipconfig and other network troubleshooting applications is an app called Fing.
I've worked on this issue far and wide. If the new ota didn't help and u still get random disconnects thru WiFi then u need to exchange your phone. It is actually a problem with the radio. My first EVO LTE did it and I could fix WiFi disconnects temporarily, but not permanently. This, my 3rd EVO LTE works great with no ota installed.
Good luck. Hope I was of some help. Pm me if u need more help.

For me, I was on a different channel than my neighbors with no other wireless device ever had a problem in the 12 years I've been there.
What I do, Go into wifi advanced and click on the high-performance setting.
Only use it when needed as it burns battery.
Post back if it fixes the drop issue for you. Fixed it for me.

Last night I flashed the awesome kernel and set the frequency to 2.4 seemed to go away. Today I flashed tranquility rls 1.a and I'm running it as is and having the issue again . I'll try out your suggestion throughout today and tomorrow, thanks for the tips guys!

I've been hearing about people talking about the wifi issues since day one, but never actually run into them. The past few days though I've been trying to stream and download things (exporting through dropbox) over wifi, and OMG, what the hell is this? Every 2 or three minutes the connection just stops - the wifi bars at the top still show the wifi connected, but the the stream or download just stops. Sometimes it starts up again, sometimes I have to disconnect from the wifi and reconnect. And the whole time the wifi indicator doesn't indicate any loss of signal - once in a blue moon though you'll see it disconnect then reconnect. I don't want to hit that high-performance setting (although it seemed to help the in the limited time I used it), because it uses more battery. I thought the update was supposed to resolve these issues. I know I never had these issues before the update. None of the tricks mentioned in this thread seemed to help. Just wanted to report the issue in case some other people are having it also, and hoping an update will come out in the near future to resolve it. On Viper4G, btw. If have time at some point, I'll try to flash another rom to see if I get the same issue.

It's kind of strange,mine has been dropping but the actual indicator in the status bar goes off when it does.I've seen it connect and disconnect 10-12 times per minute.I'm also running latest firmware/radios on the latest version of ViperRom.I'm also running Enoch's Kernel but not sure if I had the problem before the kernel flash or not.
im having the same issue. ive only really started noticing it because i was running chameleon pretty much since i got the phone and this never seemed to be an issue. now im on viper4g and my wifi will drop sporadically. it drops, i see the 3g icon for about half a second, and the the wifi reconnects. sometimes itll do it just once, sometimes itll do it continuously... the longest ive let it go before interfering is about 30 seconds. but my battery usage screen tells me that it goes on for way longer than that if left alone.
anyway, im on the lastest firmware, and i have the channel set to 2.4 (5 seems to knock everything in my apt, including my phone, off the router). i use the best wifi performance option sometimes, but as has been mentioned, it drains the battery. the phone wont sleep with that option checked. also, it seems to happen more frequently when im on the opposite side of my apt from the router.
ive read stuff about using a screwdriver to pull the antenna pins up a little, but that scares me. i dont really think that has anything to do with it anyway as ive tried that test where you squeeze the phone to see if your signal changes. it doesnt.
really, im kinda at a loss here. im thinking that i might try to exchange the phone if i cant get this figured out soon, but i dont want to do that if its something with my router or if the replacement is going to do the same thing.
I am using Viper 4G and have been having issues with my wifi connection dropping but more recently my phone has been restarting only while connected to Wifi. I haven't tried changing the wifi Frequency band to only 2.4GHz , but I will once I get home after work. I hope it works because its getting kinda annoying to have my phone restart so much while its just sitting idle.
I believe the rapid connect/disconnect issue some of us are having is also related to the phone not playing nice with particular routers. HTC referenced that fact when the 1.22 OTA came out. The changelog said the issue was fixed on how the phone communicated with certain routers and the disconnects should be eliminated. I can attest that the new update has made it a little better, but still not 100%.
The router at my work has been perfect, I've never disconnected from it once.
The router at my house is a whole different story. I have given up on downloading a ROM with my phone, directly to my phone. I will start the DL, sit the phone down and go do something, only to come back and find "download unsuccessful" every single time. I know it is because it is disconnecting. I can sit there and watch it happen.
The router at my friend's house is fine. Connect once, and never worry again the rest of the night. Obviously I need a new router. More obviously, HTC's software needs fixing. I shouldn't have to buy a new router just so one of my devices can stay connected to it.
Interesting seeing all these reports of dropped connnections with Viper4G. I've been running it for a few weeks and have never had a connection drop while it was in use on either the 2.4ghz or 5ghz bands of my d-link router. This thread over here suggests that replacing your Sense Settings.apk with an AOSP Settings.apk solves the problem for some people. I can't verify since I wasn't experiencing disconnects, but the AOSP menus are cool anyway
http://forum.xda-developers.com/showthread.php?t=1824465
My issues (detailed above) have apparently resolved themselves. I haven't lost connection once today, and I was streaming and downloading all day.
I don't see how this actually did anything but here's what I did. I decided to try another kernel instead of the stock one that comes in the viper rom. I knew the wifi fixes that HTC supposedly made were in the new kernel, and I knew I wasn't having any issues until I updated, so I thought I'd give a custom kernel (based off the old base) a shot, and play around with some new governors and overclocking while I'm at it. I did a nand backup and flashed awesome sauce. Wifi issues were gone, but I didn't like the kernel, stock seemed smoother. So i restored my backup, and for whatever reason, my wifi issues remained gone. Like I said, I can't explain it, but there you go.
Nice to know I'm not alone with this. My Wifi drops every so often, particularly at night time or with downloads. Hopefully HTC figured out a way to sort this out 100%.

If you have a wireless router like myself that operates at two distinct bands, go into your Wi-Fi settings and choose the band that is at the higher range, and setting best performance is also a good idea, although this might result in greater battery drain. HTH!

Hello all!
I have been getting very low wi-fi signal on my nook since I upgraded from stock to CM10. I know its not the router , as it was doing fine with every other device on my network.
I'm on CM10, have tried the three major roms out there for CM10 ( PURE, sgt7+cherry picks, codefireX) just to see if it was rom side.
I'm just wondering what are my options here ? I can't walk outside my room without dropping the already weak signal .
I not having the same problem from crossfireX or earlier builds of PURE, sgt7+cherry picks. Make sure you wipe dalvik and factory reset wipe before you flash a rom. Try a router firmware update then start test by setting up g band only then setup n band on router if successful.

I have wiped dalvik and factory reset with all the roms I have flashed, and nothing is changing. Also, I have the default Verizon FIOS router(checked, firmware is up-to-date) and its on b/g mixed mode. I don't believe it can do wireless-N.
Let make sure it not the rom in question for you. Can you connect to like a friends, neighbor or a nearby hot spot which could simulate the same problem? If you connect with high bar within proximity to the router, then you know its not the rom. Do a speedtest.net or use the app on your device to test if your getting at least 12 Mbps. If you are getting higher rate then I would just ignore the bar.
Well looky that, I'm a Senior Member today, I guess I can get my discount at Ihop now.
Other ways of using a Intel laptop as a router is to have Intel My Wifi Utility to enable a hotspot function or ad hoc network test for your nt. Just a thought.

I have a spare linksys router I tested. Almost identical results were found. Should I re-flash stock and start from the beginning ? I mean, I can't take more then ten steps to my bathroom without dropping the signal.
I also did a speed-test.net , and got 12m/bs down and 4m/bs up. but that doesnt mean anything unless I'm inside my room.
Sounds like a good idea. Try this before the reflash. On the nook, how many access point do you see with 5 bars, if there is more than one then it's causing interference. Try setting a WPS pin in your router and in CM 10 describe in the "WPS Pin Entry" on your nook in wifi>touch the 3 dot in vertical alignment.

Bump....I'm having this problem with my NT too. OP did you ever solve this issue?
It was working fine for the passed 2 months, now it can't pickup any signals unless it sits a foot or so from the router. This sucks. Its basically rendering the tablet useless.
And so far what I have done:
Updated rom, wiped & reflashed, flashed new rom, nandroid back to updated rom. Only thing I haven't done is try a new kernel ( didn't think it would make a difference)
Fully checked router, all other devices on WiFi(5) are working fine in other rooms with 2+ bars.
Is there a way to check the input/output signal strength of the NT? Modifying this? It's starting to seem like a Hardware issue.
In the Google Play Store there's an app called "WiFi Analyzer" by FARPROC. Use that to check your signal strength on the router.
Bump, still having this issue, I was hoping by now there would be a solution. I'm just coming back to the tablet after many frustrating nights... To try and get it to work again.
Please this has got to be more common.. It used to work grrreat! My router is fine, my GNex has full bars, the Nook has 1 or 0 bars.
I just reflashed a new rom, updated kernal, same results. Is there a modem I need to flash or something?
What happens if you go back to stock using http://forum.xda-developers.com/showthread.php?t=1470910? Do you still get a weak signal then?
