[Upgrading, Modifying and Unlocking] malmostoso:
Well, that's the issue: on GB it is 8192cu that is loaded and it works fine. I am guessing it's some kernel/module parameter but while I'm expert in linux I don't know where to look on Android.

My tablet came with ICS, and while trying to install Google Play I messed it up, so I got CM9/CM10 on it and neither had a working wifi. Nor does any of the other images floating around for various A10 tablets.

Aaaand to complete my rant, I don't seem to be able to flash anything on it anymore, but maybe I'm not getting the finger combo right (it's been a long day).

I'll try to get GB back on, but it's not rooted so I have very limited access to the system. Also I couldn't find a way of rooting it. Yes, I'm a noob :)

Thanks for your help!

EDIT: Fun fact, I just noticed that it does not even detect the MAC address of the wifi card. I should find a log and see what's wrong.

EDIT 2: I finally got around installing adb (duh), this is the output when I try to start the wifi a couple of times
