WiFi Connection does not work

Is anyone else having the same problem as me. Running on the 1.66ROM my wifi has suddenly stopped working over the past week. It is connected to the correct connection but brings up error messages when I use Opera, sync email, weather, Twitter etc.
Because of this I'm having to use my 3G connections which:
a) isnt as fast
and
b) is taking up a large chunk of data.
I havent tried a hard reset yet as I feel that it would be a last chance scenario to do this as it was working before perfectly until the other week.
Hope someone can help.

Just bumping this.
Anyone got any ideas?

I'm having the same problem.... .is no one else having this problem???? ****!

I uninstalled the xda wifi router app and my connection worked again. Worth a shot for you....

save your apps(only apps and config of the apps no system data) with titanium backup, store the titanium backup folder on your pc
make a hard reset and flash the newest firmeware, after that copy tb folder back on your phone and restore the apps.
have fun

Just a guess, check this if problem is: '' wifi stuck on obtaining IP address from".
for me, problem was on my home router and work router was ok, the thing which worked and still working for me(I found it somewhere here only), is go to AllShare app on your device and then it will ask you to connect wifi and there you go it will connect wifi right away.
I use this trick every now and then, funny thing is problem does not occur if my home router is continually running, if I turn off router before leaving for office and in the phone stuck again and AllShare trick works all the time.
try it, may it works for you too.

Great tips, I will try this later and let you know is this works...

Thanks. Awesome tip. Have been fighting with this problem so long. Works like a charm

fine, that the tipp help you

Awesome, now everything works as a charm. Thanks a lot!!!

I agree. Great tip. Used it for a while until I flashed 2.2.1 firmware. Now all my wifi problems have disappeared.

wifi problem fixed in 2.2.1
Seems, problem has been fixed in 2.2.1 release, for those who is yet to get 2.2.1 (not talking about flashers) can go for 'AllShare' solution.

hey guys im having a wifi problem as well but it seems its kind of different from the rest of you...
my wifi is connecting fine to my router... it runs fine for the first say maybe 5 mins... and then it just stops working even tho it still connected to the router... it just says no data connection... this was happening on my 2.2 froyo then i flashed it with darkys rom 9.2 and im still having the same problem... i need to reboot my phone then only the internet works again for 5 mins then stops again unless i reboot.... its verrryyy irritating i tell you...
tried the allshare but that didnt really make a diff cuz the router is connecting... im just notgetting any internet after a few mins....
any advice would be great..

unable to scan wifi networks; auto turn off of wifi
my problem is similar. i am able to turn on wifi but it won't scan networks ("unable to scan networks"). it then turn off the wifi after a few seconds by itself.
any help?
i've done several reboots and the allshare solution, the prob persists. will do an upgrade to gingerbread and will see if it solves the problem.

I've upgraded to gingerbread and wifi issues have been solved sunbed then.

[Q] Wifi tethering stops working after a few minutes

Just got my Arc yesterday and noticed a really wired problem. I turned on Wifi tethering and connected from my MBP, after a few minutes of normal usage internet stops working. Although Wifi still shows connected on my Mac but sites will never load.
I keep getting "WPA Key" incorrect error if I try to reconnect before I restart Wifi tethering on my Arc. Thing is this only happens when WPA is on, if I choose no security it works completely fine without any issues.
I also tried connecting from my Nexus One and the same thing happened after a few minutes, so it shouldn't be some sort of conflict between Arc and my MBP.
Everything else on my Arc works perfectly, I already tried a hard reset but it didn't help. Does anyone know what else could I try before sending my phone back to SE?

anyone?
Hey did you find a solution? Or has anyone got any suggestions, I have the exact same problem. I can connect to the phone for about 2 minutes then it suddenly stops working. I then cannot reconnect properly untill everything is reset. I tried using it without security after finding this post and it works for me as well - I don't want to have it open though, im in halls of residence so people will try using it. Im on three mobile, I wondered if it is a possible problem with their branded software. (USB tethering works perfectly)
I also cannot connect to the update service through the phone, it fails everytime but there is nothing wrong with the 3g connection etc, and only the update service has problems. I know this is not important, but it could be a sign that something is wrong so it is annoying me a little
Thanks

[Q] More WIFI problems

Hello everybody.
Yesterday night the WIFI in my Nexs 7 32th with 4.2.2 stopped working out of the blue, literally because the bars irrevocably grey and they have been like such ever since.
I tried rebooting the modern, performing a reboot on the tablet and then I did a factory reset; only to encounter the same ongoing problem.
I must mention that the WIFI works on other network. I had this problem a while back and I solved it by tweaking around with th advanced setting me menu while selecting the network, however, I completely forgot what I did and I cannot find any thread that explains the whole solution.
Thanks a lot!

UPDATE; So I kept tweaking with the advanced settings and now I can use Chrome and web browsing but bars are still grey and I cannot sign i to Google Services with my account. I cannot use Gmail, youtube or Play Market.

Nobody got any idea on how to solve this?
I even disabled the firewall on the modem with no success.
By the way my modem is a Century Link PK500

UPDATE2: So I am using a whole different router and the bars are still grey... anybody got any idea?
I csn browse the internet and use apps but I cannot connect to Google Services.

A kernel is what bridges hardware and software. Try flashing a different one.

I think I had the same problem and used it by removing my Google Account and then adding it again...
Hope I could help you

Thanks for your replies guys nobody else has stepped in to help
I might try to flash another kernel, removing the acc does not work since I already performed a factory reset and problem was still there. Needless to say that i can't remove one because there are none synced.
I can use browser and stuff perfectly, however, it says it can't establish a reliable connection to the server.

Weirdest issue Data & Wifi connection but no internet???

Hi, I have got a very strange issue, I have data and wifi connected but cannot connect to the internet with either, if it was just one or the other but with both data and wifi, I have tried many 'fixes' but nothing works, I restart the phone and both work fine for a while but after I wake the phone from standby neither work again... maybe this is a clue any ideas? thanks

What does not work? Is there only a particular app that doesn't work over either one of them?
Did you ever use a VPN for this phone?
Also, do a factory reset and see if getting back to the original settings it will work.
