    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!

    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
    Code (Text):
    1. cd tools
    2. adb shell
    3. 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
    Code (Text):
    1. cd /data/wifi
    2. 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
    Code (Text):
    1. reboot
    -When your phone comes back up, wifi will once again work.

    Hooray!

    I found the answer here:

    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.
