Wifi unable to obtain IP - LG Optimus L9 P760, P765, P768, P769

The phone P769 was working fine, I factory reset it . After that, wifi keeps having " obtaining IP " from different routers/networks then disconnect. During the "obtaining IP " I can ping the phone from another device. I already try to reset router and the phone again. Any idea ? TIA

Your WiFi maybe be going out. I doubt that a system file got corrupt. You maybe having issues with busybox. Sounds like busybox replaced a toolbox applet. Just guessing mostly

Try resetting your router and try again.

i tried other wifi spots but still i got same results.. what seems to be the problem? do u think its hardware issues? i can detect all the wifi connections available but once i got connected, i cant browse or use the market. is it hardware?
also to add to the problem, i tried the bluetooth, i cant receive files but i can send files to others..
i think best way is to flash another ROM .. Wipe everything before you flash & see it it works otherwise flash Radio if you not having latest one Radio for Hero GSM Then i think VillainROM Guys are having you can check their forums ..and try that
i think i have issues with my wifi at home.. because when i try public wifi's i can connect to some but i also cant to some free wifi. which is weird. i have a wildfire before and this was not an issue for me
Last year I had a similar problem that I fixed by assigning my hero a static ip address. For some reason dhcp did not work.
Strangely enough I don't have that problem anymore.
Back then I had stock 1.5 OS. Now I have every ROM. Well, you know what I mean.

This could very well be an issue with your router firmware. Some routers are just plain ****ty.
Can you maintain a connection without any encryption (WEP,WPA,WPA2,etc)?

Wireless Tether

I havent tried using my wireless tethering since the OTA. But I just did and when pressed start I got an error message stating, "Tethering started with errors check show log" I checked the show log and see that setting ad-hoc mode "failed" and setting channel "failed" Then it goes on to say that, "Your phone is currently in an unknown state- try to reboot. So far I've runned the fix permissions in ROM manager and also uninstalled and reinstalled the wireless tether apk. What else should I try?
Try AP mobile.

Try removing security from your router, if you have one...

[Q] Sony Tablet S Wi-Fi Issue

I've had the tablet for only a couple days and after a few it is now unable to connect to wireless, I've tried other wireless networks and from the looks of things it is unable to get a IP address.
I've looked in logcat using SL4A and it says the DCHP request failed, the Wi-Fi Checker app fails half the time and when it does get to IP settings.
Oh and I've tried Starbucks and 2 hotel wi-fi's all of which worked fine before but now can not even connect, it just goes in a loop getting a IP address.
Oh and I tried doing a factory reset and that did not work.
I'd take it back

Yeah. If the factory reset failed to correct the issue it's probably best taking it back.

Can't connect to home wifi

This happened in front of my eyes, I downloaded the new walking dead game and half way through it disconnected me from the wifi and now I'm getting all sorts of errors like: being stuck on Obtaining IP adress and failed to retrieve IP adress or something like that and Cant connect to wifi because connection is too slow or something like that. Now I'm stuck on using mobile data.Searched for solutions but didnt find any and I dont want to do a wipe.

First step is to flash latest firmware and factory reset, if still the same afterward then it's hardware.
