(Help) WIFI not working (grey icon)

For some reason my wifi stoped working.
i was on revolution 2.1.0 and it stoped over night. without me doing anything. It cant connect to wifi - to any wifi. it says the conexion is poor or even the wifi bar is full but the device cant obtain the internet. the icons stays grey wifi is there but no internet.
so what i did was
1. flashed different radios xxkk1 - xxkk6
2. flashed stock with odin from chainfire
3. flashed different kernels
4. flashed different ROMS - cm9 and pauls and then back revo 2.1.
and no such a luck. nothing helps- wifi icon stays grey.
i did full wipe before each flash. and no change.
and somehow after 3 hours wifi came back. without me doing anything.
I am just scared what it could be. did someone here experienced the same issue? how did you deal with it?

Have u checked your wifi band? 2.4ghz vs 5 ghz? Compatibility with your router?

i did mate. but i left it on auto. anyway it was working before like a charm. and then it stops. i also tried different routers - wifi's all are ok. phone locate them connect to them but the icons stays grey and no internet.

I'm having the same problem.
I've tried Revolution 2.1.0 and 2.1.2 with the same results.
It seems that it just stop passing traffic though the WiFi icon shows the up and down triangles as if traffic is passing. But no packets actually flow.
Usually I can turn off the wifi, wait a few minutes and turn it back on.
Same thing happens to my 3G and 4G icons. They'll grey out but indicate traffic is passing, yet it's not.
I haven't gone back to the stock rom yet because the problem is sporadic enough that I can't make it happen consistently enough to test it.
I'd like this problem to go away. Thoughts and suggestions welcomed.

Hi - same problem. Was your connection solved?

Hello,
I see that your thread ended without a solution to your Wifi connection problem I have a samsung galaxy nexus that has the same problem. I have tried the same solutions, but have yet to find one that works. My data works find, but I prefer to move between Wifi locations to keep my costs down. Where you able to solve your problem...on this site or some other site? Would you mind sharing your solution.
Thanks,
Scott

Had the same problem. Gotta do a fresh install. Wipe cache and dalvik twice and the install. Worked fine. Or you can just wipe dalvik and cache and see what happened. Might work.

Wifi not working after phone has been idle for a while

This started happening to me couple days ago. My phone is connected to wifi at home, and whenever I want to use my phone after its been in idle, everything looks normal. The wifi signal is there, but there is no data, I cannot check email, browse internet, anything with data. Only way to fix it is to reboot or turn wifi off and then back on. Everything is fine when I'm on 3g, there are none of these issues. I am on Calk 2.7 (not 2.8) with the latest kernal, EL28 (I think thats the latest).
If I have an app running in the back that is constantly using data (google music) (recall, ONLY on wifi, NOT 3G), the app stops working whenever the phone goes into idle, I guess. Basically leaving a data consuming app ruining in the background did not help the issue.
I have tried searching, and some other people have experienced the issue on different devices (NOT epic touch), but no threads offer any solution(s).
Any help would be greatly appreciated.

I had this issue on my previous epic touch and I took it back and exchanged for another one and the one I have now doesn't do it. It had the same problem u describe. Might want to check your router first though since it just started. Mine always did it and it did it on other Wifi networks. Good luck.

I've seen this happen on four different E4GTs. It seems random and only occasional. I've seen it on EG30 and EK02 stock, I haven't tried other "modems" or roms yet. I'm not sure what causes it, but a quick wifi toggle seems to fix it. Seems like the wifi radio just sort of "freezes. " Wifi sleep policy set to never, doesn't seem to make a difference. Minor annoyance.

What baseband are your running? Have you tired another baseband?

I didn't think the modem has anything to do with wifi. I have this issue on certain wifi networks I use. I have made tweaks to see if it is security settings or what but haven't figured out a pattern yet. I use a wifi widget and it looks like DHCP hangs up cuz it won't give it an IP. I reboot the wifi router and it works right after evertime. I will sometimes powercycle wifi on the phone and it will work. I really think it is a wifi router setting for the network but not sure which yet.

Sightly strange WIFI issue

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,

WiFi behaving erratically

Hey Guys,
lately my wifi is been acting strange, I have full signal when the phone is idle but the minute I start using it the signal drops to a 1-2 bars or just that dot.
There are times it just disconnects from WiFi and connects after a brief moment with full signal. I am noticing this behavior when I do something WiFi intense. How can I get to the root of this problem?
I am currently rooted, running MMuzzy ROM with Trinity kernel. (I tried stock kernel too and it acted the same)
Any help appreciated.
Thanks

Have you installed the latest radio? :S might be best to do a clean install (google image)
edit: You should try with different kernels aswell it might be possible that trinity isn't acting well with your phone not that i'm bad mouthing trinity .

I'm on the latest radio, I tried various kernels and they all act the same.
I'll have to give Google's image a go.

So it went well?

T-Mo 3g connection Issues??

I have been having some connectivity issues and I was wondering if anyone else is experiencing the same thing. It will happen randomly during the day, where I will have full bars of 3g+ but yet when I try to use the browser or any other applications that uses the internet (instagram, FB, etc) nothing will load and eventually time out. Rebooting and turning off 3g/2g/mobile network and back on does nothing. Connectivity seems to come back whenever it feels like it. Ive talked to one of my other friend and she has also experience the same problems on her Note 2 and neither of us has reached the 5gb cap either. Are there any fixes for this?

Have you tried flashing a different ROM to see if that corrects the issue or going back to stock? maybe flashing a different modem my work
