Serious Issue with my phone(WIFI and SCREEN)

So I have no idea how this came to happen but i am currently having issues with my phones wifi. Each time i turn on the phones WIFI and connect to any network it kills both the 3G data and the WIFI data, making it so i have to reflash a new rom to use data again. Another issue is that when i turn off my screen if i am connected to the wifi it will not turn the screen back on unless I do a battery pull. Lastly if i go into settings to try to turn off WIFI i get a force close and have to reflash to get my phone running again.
Things I've tried
1.Flashed New Rom
2. Flashed New Radios and Kernels
3.Connected to multiple wifi hotspots
4. Used a RUU to reset to factory settings
5. Root and Unroot
6. Tried new SD card and Battery

Do me a favor and take a screenshot of your "about phone" information. Also, which recovery are you using? When did all of this start? Now when connected to a wifi network, it temporarily disconnects your 3G data. That is normal. You also stated that it disconnects your wifi data. Please explain?

When i connect to wifi it makes it so no data works. Ill post a screenshot of my phone.If i connect to any wifi hotspot and try to connect to the internet nothing connects it fails everytime no matter if it use 3g or wifi after that until i reflash my rom

You don't, by chance, have an adblocker built into the rom you're using, do you?

I was using CM7
I have tried almost every rom and even used the RUU from sprint to bring it back to default and rerooted it,i'm using hardware 002 and wondering if its possible i messed up my wifi when i used the 802.11n patch a while back also do you think flashing someone elses nanroid could fix it?

Also when i hit wifi it will get stuck saying turning on and wont allow me to do anything on the phone until it is reset

I do not recommend flashing a nandroid from another device, however, I do recommend flashing a different kernel. Kernels can have an effect on wifi, the camera and other things.

i flashed a few different kernels

Well, you may have to call Sprint and have them troubleshoot from their end.

Can't connect to wifi...

So I'm s-off and rooted running cm 11 nightly from 11/23. I was able to connect to the wifi at my apartment just fine then. Now however, whenever I flash any new rom after wiping both caches and what not, whenever I go to connect to my wifi I instantly get a "failed to connect to network" notification. I can't figure out what's been going on but I keep having to restore back to my nightly backup that was already connected to WiFi. When I attempt to connect anything else to my wifi I have no issues, just my phone after a new rom flash. Any insight?

[Q] Data connection randomly disconnects (Carbon JB ROM)

Hello,
I have an issue that my data connection (internet) keeps disconnecting randomly and I either have to switch it off and on again, or turn airplane mode on and then off, or even restart the phone to get the data connection working again.
Is this normal for this rom? is there some fix for this? For a first few weeks everything was fine, but now it is intolerable.
I had this issue on stock rom too, but only a few times, when I completly lost signal, I had to restart the phone.
Help! i don't want to flash the rom again and start from scratch again
Thank you in advance!:laugh:

No one can help? Anybody facing the same issue?

Hi, I seem to have the same issue. I deleted the other unused apns and now it seems to be better, but I just did this now, so in not too sure myself yet. Any help would be appreciated.
// didn't help

SOLUTION
hey there,
i think i found the solution, you need to install a KK modem (i assume you have a KK rom)

In Odin uncheck reboot phone before you start, reboot manually and flash twice.

3.35.401 firmware internet issue(Wi-Fi and data)

Since updating to mm firmware..I've used all mm roms on here with full wipe.. I constantly get internet stalling on all browsers and random Wi-Fi and data disconnects ..never encountered anything so frustrating..
For example I'll type apple in browser search it loads 5% stalls then internet disconnects and have to re search apples.. Wi-Fi icon shows disconnect and mobile data doesn't kick in..I have attempted on different Wi-Fi and it's still the same..there seems to be an internet loading/ Wi-Fi and data disconnect Issue for me on mm firmware.. anyone else experienced this phenomenon??

More info.. wind mobile Canada..believe I have att variant..which wind sells in Canada..
Slow Wi-Fi and disconnects..should hand over failing Wi-Fi..to mobile data network right??but just stalls and disconnects when loading pages..constantly..

Which rom are you on now?
Does it jump to and fro on wifi data or is it a flatout disconnect and you have to manually reconnect?
Does the data stay disconnected outside of wifi range or is that bouncing on/off too?

I'm on leedroid now but it's the same on all roms..it disconnects then auto reconnects Wi-Fi and mobile data doesn't kick in to load the page. I believe data must be disconnecting too or else it would kick in a load the page but pages only finish loading after the Wi-Fi reconnects

Leedroid. There's your problem!.
There has been known wifi issues on leedroid. I recommend flashing the rom twice and do not restore wifi settings if possible.
As for data connection you should be prompted at the setup to select your carrier which in turn selects the correct apn. You need your simcard in at this point as it uses the sim to determine the carrier settings.

Lee droid.. not the problem..does this on all roms so far as previously mentioned..except one I hAdn't tried. And will tomorrow. Arhd. My apn is set correctly.

Did you restore the settings from an app like titanium backup or the likes?

Seemed to have fixed it..
Mobile data--network operators-- clicked wind home network..it registered on the network again and seems to be fixed ATM..will update if not..possibly it altered somethig..thanks

Not fixed tried more roms..Wi-Fi and data keep auto disconnecting..maybe try reflashing 3.35.401 firmware? as its not a rom issue

be sure that you Flash it a second time, as the first one does not update all partitions
