wifi stopped working

somewhere along the lines of rooting or just playing around wifi stopped working. It stopped right after i added a hidden network and it connected. Now it just won't work. it tries to turn on and then just turns off. strange thing is that wireless tether works fine...
HELP~:?!
TIA

Same thing happened to me yesterday bro, tried everything to fix it and no luck, had to hard reset and then it's working again. Sucks I know, just make sure you back all your stuff up, I used "My Backup Pro" to backup my apps, contacts and data, search on the market.

Yesterday while trying to see if wifi tether or barnicle was working for the epic my wifi has seem to also stop working already tried a hard reset with no luck both apps have been uninstalled any suggestions?

What happened after you reset the phone? Would wifi turn on they say "unable to scan networks" then turn off? Or it wouldn't turn on period?

It says it is turning on and it also says its trying to optain an ip but then disconnects over and over. Its not my network since I am still able to connect with both my ipad and laptop.
Thanks in advance for any help!

Ok try this. I noticed when I turned wifi on after resetting the phone, it would scan networks, then totally stop working again so I had to hard reset again, after I hard reset right after I turned wifi on again I unchecked "notify me when an open network is available" and it's been working fine for me since. I honestly don't know why this happens but I haven't had problems after doing that, worth a shot for you.

Hey thanks for the help that seemed to work! Very strange

You're welcome. I'm glad it worked for you, but yeah it is very strange how it works fine after you disable "notify me when an open network is available". Samsung needs to sort this out, prolly a software problem

Also confirmed turning off network notification under wifi settings magically made wifi work again..... thanks man!!!

Wifi connection issues

I have a problem connecting to wifi on my home router. Whenever I try to connect to it, it just says "Obtaining IP address from" then it would later go on to say "Disabled". I have entered the password correctly, made it forget the network and connect to it again, and have restarted both the phone and the router. That has not seemed to fix the problems. On other networks such as the free wifi at Border's or others it would connect just fine. I'm currently using Cognition v2.3b8.
Any suggestions? Thanks
Edit: Nevermind, I did a factory reset and it seems to be working now.

Have you tried android id changer? Not sure if the cog version you are on will let you write the new id or not, but worth a shot

Ok...I just tried that, it didn't seem to change anything. Thanks for the suggestion.

Seems to a 2.2 "intermittent" non-predictable issue. Faced this sometimes when on 2.2.

I have the problem but in reverse
I am using 2.3b8. I can hook to my home protected wifi but can't hook to any free open wifi connection

I am also facing the same problem as Slow_DC4...
Any help would be really appreciated ....
Looking forward to hear from you guys

Sarveshsj: I ended up reflashing the ROM and it fixed the problem, so you may want to try that.

Problem: Mobile Data not turning off when I use WiFi

Pretty much as stated in the title. I rooted and installed the stock Inspire rom with sideloading and all that jazz from attn1. Before I rooted, when I turned off WiFi, it turned off Mobile Data (gave it a check mark under H+ instead of 2 arrows). But since the root, it doesn't do that most of the time. Sometimes I can fix it by going into Airplane Mode, enabling WiFi and turning off Airplane Mode. That'll fix it sometimes. What's going on? Anyone got a clue?

Try checking what apps you have running in the background. I've seen that sometimes some programs will try to use mobile data even if wifi is on. If you go to Settings>Apps>Manage Apps you can try closing apps using data one by one to see if after you close a certain one mobile data disconnects. Try any AT&T app especially.

I tried shutting down all the running services and such, but it didn't fix it. I installed "TrafficStats Lite" to see what's drawing the bandwidth, and it just gives me "Total GPRS/EDGE/3G 55 kB", no programs using it. If I intentionally run a program on 3G, it shows up there. I'm stumped.

I had the same problem. I rebooted and problem solved. Also you can put the mobile network widget on your screen and just turn off the network when on wifi.

Check the apn set up. I created an apn to enable WiFi hotspot w/o data tether plan. When using my created apn my data never turned off either. Upon switching back to Medianet data was turned off and my "check mark" under the H+ was restored. Hope this helps.

[Q] WTH T-Mobile?!?

First let me say I love my G2x overall and I have no desire to return it or even leave TMobile. But.........
Let me start this by stating that I have Verizon fiOS at home and a Netgear Wireless AP. My phone and various other equipment connect to the Netgear for internet access. I've noticed on my phone that at random times I have a full wireless signal and 4G (2G or G, depending on the time of day I suppose) on my notification bar. I originally didn't think much about it thinking my wireless would override the 4G.
Well I decided to root my phone and use BloatFreezer to freeze some apps (MyAccount, Qik, TeleNav, etc), plus I believe many feel that MyAcount is the cause of this, but with all 3 instances of it frozen is it still the reason behind this?
Last night I had it happen yet again and I ran speedtest just to see which of the 2 was the main one. Well not to my surprise the cell data was overriding my wireless.
I'm (hopefully) attaching the 2 pictures I took. One with the celldata active and showing what SpeedTest reported and a 2nd with cell data off and the new speedtest report.
My basic question here is what service/app/etc am I needing to freeze to avoid this again, it's extremely annoying when I'm trying to watch youtube only to have my phone in the middle attempt to use cell data and it can't due to reception and boot me from the video, or when I'm downloading from the market.

I noticed this also. Usually when opening up Market or My Account. I know for fact that My Account only works over cell tower so it will automatically disable wifi and bring back 3g. Dunno about Market but I suspect the same.

just get an app with a widget to turn off data when you are using wifi???? I dont have this issue at all so I can't really help much, but its an alternative, for now.

Doesnt wifi calling turn data off completely when connected? Could try that.

Correct. This would work.

Believe its the tmo my account app, freeze it and see if it helps.
G2X

I have myaccount frozen already. My wifi calling turns on whenever it feels like it, it sometimes turns on right away other times it takes an hour or so to finally connect. Ill keep an eye on this when wifi calling is on to see if my issue is still there.

It might be the Market app. I get perfect Wifi unless I open up market app or any app that access the market.

I just turn wifi off and on again. Fixes it. Not that we should have to.

For the life of me, I can't get MyAccount.apk to stop running. Its frozen with TB, and I moved it out of /system/app folder.
Its always in the foreground in SystemPanel...

just delete the apk all together and reboot...

bloat freezer app's default will freeze an app more completely than titanium backup will. it also has the partial freeze option like titanium does as well. after freezing with bloat freezer it disappeared from even titanium backup seeing it.

Ok I've had wifi calling enabled all day and sure enough 2G came up and took over data service for no apparent reason, I wasn't in the market app or myaccount. I was simply texting when I noticed it, I ran speedtest again and verified 2G was the active service even though I had wifi on

I also might add that I have SwitchPro on and when I have wifi enabled the data connection is shown to be disabled (tells me it gets disabled when wifi is active) but I still had the cell data icon on and overridding my wifi. So obviously disabling my data through a widget doesn't solve my issue.

Wifi icon not green.

I'm having problems with my wifi icon not connecting to the Google servers.
My 3g icon is fine and goes green, but when I connect to my wifi, it stays white and I cannot access any applications tthat require data connections.
Has anyone had similar problems?

This only happens to me when I'm using a hotspot somewhere. I'll have to load a webpage and click to connect. Only time.

I've had that happen to me a few times... just put it in airplane mode for 10 seconds and take it back out. Fixes it for me at least

Sounds like your router is not passing along the internet connection. Try restarting your router.

I get that on my home network once in a while. It'll connect to the internet, but not want to cooperate with Google's servers. Then 3G will work fine. Not really sure what the deal is. Probably some issue with Comcast's local servers, I dunno.

what mode do u use for your wifi? i was having the same problem and it was driving me crazy since i would keep getting errors like "disconnected" and "no active network connections." i switched from WPA2 Personal to WEP and now I'm not having problems anymore.
on a side note, does anyone know if i need to do something special to get WPA2 to work better and not keep disconnecting?

Every wifi network I use is wpa.
In the advanced wifi options, is your wifi sleep policy set to 'never'?

i have it set to never when plugged in. but if the screen is on, shouldn't it not make a difference?

it sounds like you dont have a data connection at the moment. check your internet via a desktop/laptop. also try unplugging your router then plugging it back in.

well my data works on my laptop and ipod touch - never with any problems. so it's strickly an android problem. but now that i've changed to WEP i haven't lost data connection at all today. the bars turned white twice, but i didn't lose connection like i did with WPA. very strange.
