I have a Acer Aspire One netbook, with a AR9285 Atheros wireless card. I've installed fedora 16 recently, and everything else works out of the box, but the wifi is very, very unstable (which is really annoying). I basically using two types of connection (college network and company network): One is WEP 40/128 bits, and the other is WPA & WPA2 Enterprise, with PEAP authentication. On both networks, I can connect, but it keeps dropping randomly. Sometimes it stays stable for an hour, give or take a few minutes, but then it drops again. I tried downgrading to kernel 3.1.0-7, and it got a little better, but still very unstable and annoying.
