Wifi not working - LG Optimus L9 P760, P765, P768, P769

I rooted my phone earlier today no problem. When i used a wifi password recovery and backup to restore my wifi it has caused my wifi to not work. The wifi will look like it's searching for a network ,but wont show any networks. I've done a factory reset and used my backup I made before rooting to try and fix this. Nothing has worked. Should I redo the root and see if that fix's it? Thanks

Does your phone detect any wireless networks?
You could try logcat to see what happens.

It's not detecting any networks. I will use logcat and see if that shows the error. Thanks for the reply. I don't think i messed up anything permanent.

used logcat
I get the follow error in logcatE/wifiHW ( 282) Supplicant not running. Cannot Connect.

Thanks for the reply. I downloaded a cwm backup. I will try it tomorrow and post my results.

nobody can actually help you if you dont inform about your L9 variant and which rom you have flashed or restored. Directly flashed a KDZ file or was that a CWM backup of someone else.
Please always be descriptive and dont make people assume many things for you. Otherwise you will always get solutions in wrong direction.

I'm a newbie to forums

My L9 variant is the LGP769V10G. I used LGP769_AP[6].bin and FACTORY KDZ OF V10G USA Tmobile to root and flash. Worked great and was really easy. Then after the wifi password restore wifi went crazy. Sorry about not being descriptive. I'm new to forums. I didn't mean to post this in general as well. I was posting from my phone. I've got everything with CWM downloaded and I can boot into recovery mode ,but there is no CWM backup folder on my external SD to put the recovery folder in.

Got wifi to turn on ,but wont obtain IP

I've flashed with CWM back up that matched my L9 and the wifi will turn off and on ,but wont obtain an IP. Now when I install rooted applications my superuser wont grant access to some files. I'm starting to get really discouraged.

Just live and learn I guess. Do cwm backup right after you install recovery. Sure, using someone elses backup might be fine but you really don't know what you're getting.

Did my flash over again with the Root files and my wifi is back up and running. Thanks for everyone that commented on this thread with ideas. If anybody ever runs into this problem again I will be able to guide them.

I agree. The backup worked though. I've learned a lot from the past 2 days. I had some knowledge of rooting. I'm not saying I'm nowhere near an expert ,but I used your root guide and it was very beneficial. Just wanted to say thanks.
