WIFI not Working - LG Optimus 2x

Recently I updated my phone LG p990/optimus 2x to ICS 4.0.4 original V30a, by AIO toolkit,
everything works fine, but now the Wifi does not work.
Let me give details
================
when i turn it on, it discovers networks and immediately say the network is out of range.
i try several tools from playstore to repair it but it does not work.
the apps from playstore always say inactive. i tried wifi fixer, hotspot problems, etc.
However, the portable wifi works, - meaning i can broadcast wifi from my phone but i cant recieve,
my data charges are becoming huge.
Your Help is really appreciated.

[Q] Fixing Wi-fi without reformatting?

Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.
I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.
Bump :x
Anyone have a solution?

Wifi No Longer Works AT ALL

My DROID Bionic's wifi doesn't work at all anymore. It was working just fine a couple of days ago. The phone got REALLY overheated so I dont know if that was the issue. When I go into wifi settings and try to connect to a wifi network it only says "Turning wi-fi on..." I was running the ICS leak .2233 at the time and FXZ'd to .902 and updated to stock ICS. Also, when I try to connect it also says "No nearby Bluetooth devices were found." Its odd because im in the wi-fi tab, not the bluetooth tab. I would really appreciate some replies. Thank you.
WiFi on mine stopped working in stock ICS. It would just continually attempt to grab an IP and then disconnect and reconnect. Forgetting the connection and reentering the key did not help. Oddly enough it worked fine in CM10JB. Not really wanting to mess with it I did a factory data reset (after backing up both ROM slots) and it started working again. It may have been heavy handed but it's going again...

[Q] Wifi issues - connected to wifi but no data

Hi folks
Since I updated to JellyBean (JellyMod currently) I have an issue with my wifi connection.
It shows connected but i cant transfer any data (every app fails to establish a connection) until I turn off the wifi and turn it on again. then it ill work for some time and fails again after a not defined period of time.
I found a lot of threads regarding similiar problems but I did not find a solution yet (and for me having a rooted phone installing an app that that runs in background like wifi fixer is a workaround, not a fix
I already did a complete factory reset and fresh install of jellymod.
My router at home is a netgear wndr3700 with the latest dd-wrt. all my other devices work great.
I set the wifi of my i9070 to always on. also i installed auto wifi for location based wifi on/off-profiles.
all of this worked with gingerbread, never had problems...
any idea? seems like a lot of galaxy phones and even tabs are affected...
Thanks in advance!

wifi problem

hi,
i installed cm11 and cm12 on my Motorola droid 4 and in both i have the same problem, when i use the wifi sometimes the internet stops in the mobile but the wifi is still connected, when i turn the wifi off and on again it come back. i don't have this issue with cm13 but android 6 is heavy on my mobile. i tried some solutions like delete /data/misc/wifi files and reboot, change wifi advance settings, nothing works.
when i download my apps from the store randomly the internet stops but the wifi keep connected and sometime it come back by it self, but mostly i have to turn on and of the wifi or reconnect again to the network.
also i make factory reset before install the rom, i used these roms (cm-11-20150201-NIGHTLY-maserati.zip, cm-11-20150901-SNAPSHOT-XNG3CAO3G0-maserati.zip and cm-12.1-20160120-NIGHTLY-maserati.zip)
is there any solution for this issue? please help.

WiFi connection problems after update

Hay guys,
I am really at a loss, so I hope you can help me here.
WiFi on my phone works totally fine until I install the EMUI Update 10.0.0.185 (and later).
From that point on, I can't use my WiFi at all. The Phone is still showing me a list of all the available Networks, but If I want to connect to one of these, the phone's WiFi turns off by itself. Just du turn itself on again a few seconds later... and turning off again eventually.
This happens to all of the WiFi networks, I've tried. Also I can't setup a WiFi hotspot anymore or use wireless display feature.
If I reset my phone to the EMUI-Version it came with, everything works flawless.
Any idea, what could cause the problem?
