[redvolvo77]

Just a quick question for everyone that has done the OTA update. Is your Wi-Fi- working. Mine will not scan for networks and just turns the wi-fi- off. Thanks guys and gals!

try rebooting couple of times...the update doesn't seem to apply changes in one go.

I had the same issue once. Scanning for wi-fi networks showed none even though there were wifi signals around. I had to do a factory data reset on the phone to fix it.

A couple days ago I my wifi stopped working.

My phone is rooted, and this is what I did to fix it:

Get the USB drivers from Samsung: they work for me on Win7 x64

Download the Android SDK Android SDK | Android Developers

Connect USB to phone with USB Debugging ON (Settings/Applications/Development)

On your computer open a Command prompt (I ran as administrator)
cd to SDK install directory

cd tools
adb shell
su

- This means "switch user" and elevates your command prompt to root. A prompt will come up on your phone and you need to allow it to run
- Also, this means you are running as root, so be careful, not my fault and whatnot

cd /data/wifi
mv bcm_supp.conf bcm_supp.bak

-you can look at the file first if you want, just type "cat bcm_supp.conf", it is the "secure credential storage" where all of your wifi SSID/passwords are stored in plaintext

reboot

-When your phone comes back up, wifi will once again work.

Hooray!

I installed that update too and the same exact thing happen. You're not the only one buddy. Hopefully they fix it soon and we'll get our wi-fi back.

Since the update I have to manually turn off and on my wifi at the house. It'll be on but not connected. Turning it off and on helps.

I found this article that gave me a complete how to, from start to finish. I am a novice and I was able to complete the steps and get the wifi back up and running. The earlier post gives the info if you have a rooted phone, but I did not, now I do. Samsung Galaxy S wifi fix

I hope this helps someone else.
