What to do if WiFi MAC Address is lost

Posted by : Unknown Friday, March 15, 2013

Many times after screwing with kernels and other tweaks I've managed to ruin my WiFi module thus making me unable to connect to wireless networks and it makes you wonder what has happened.

Known symptoms:

If in the MAC Address field it says "unavailable".
You try to turn WiFi on but you get error or it keeps turning itself off.

Usually the sign to figuring out whether you screwed up your WiFi or it's just the router is to take a look if you have a MAC Address displayed on your WiFi settings. If you don't, you've definitely killed your phone's WiFi ability but only software-side ofcourse.

Now if that happens you may jump to the conclusion of flashing a stock rom with Odin or again switching kernels if you are not aware of the following procedure on solving the problem very easy.

Instead of going through he hassle of flashing other roms or kernels, you can simply flash a zip file containing the WiFi module that will solve your problem immediately.

Below are the download links to 2 variants:

If you are on a stock kernel - Click here to download.
If you are on a custom kernel (this one has been reported to work only on whitexp's kernel but you could give it a try) - Click here to download.

Now that you have downloaded the zip file depending on what you have on your Galaxy Young, we can get on with the fixing.
