Hi, just installed the OS and got my first password(from my house wifi)!!!
Incoming problems...I'm here for you...

Also I had the same problem with an atheros card(don't remember exactly the name) and I solved by installing the bt4 r1 instead of the prevoius release.

Hope this could help you, good luck!

Solved!!!
First I tried with apt-get ugrate to see what could happen...but all went worse...so I decided to upgrate the kernel but with no result at all...
Then, and I was really desperate at this...

Hi, I install bt4 from usb and everything went just fine...until I discovered that the wirless wasn't working...

I tried to find the drivers but Acer seems not to make unix drivers for Athlon...
