And that is ACER not ASUS,, names are too close..

System locks solid anytime I've tried to access wi-fi. It's a new machine, works ok in Windows. I'm just running live USB. So far, it's happened every time with Ubuntu 11.10 64 and 32 bit and Linux Mint. In the 64 bit U I also get a WMI error.

The card is detected as AR8485 and us using ath9k driver, in Mint at least.
