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.

[Q] ] Hyperdrive RLS8.1 Wifi not working

Can anyone help me please. I cleaned install the new Hyperdive 8.1 ROM but for some reason wifi doesn't work. I thought it was a bad download so i re downloaded it and reflashed, but once again wifi wasn't working. Whenever i go to settings wifi is automatically off and when i try switching it on, the switch quikly goes back to off. And in the Quick settings in notification bar , the wifi button is like a dark green as if it is trying to turn on but never does. Can someone please help?

Check out the original thread on xda and go to the second page. There were some people, myself included, with the same problem. Apparently changing the kernel fixes the issue.

Wi-fi should work the same, if anything you should have data or network problems.
Try booting into recovery (Volume Up + Home + Power, hold together). It doesn't require root, you will be in Samsung's stock recovery.
Clear only Cache then reboot your phone. This will not clear your data or apps, this will simply delete their temporary files and force them to re-configure themselves to adjust to your current phone's state.
Maybe try connecting to a different wi-fi connection?

[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)
