I'm using U45JC (ASUS) which has AR9285 chip, and the situation is more adverse.
After 5 minutes - 2 hrs or any time duration, the chip just disappears. It is not shown in iwconfig or ifconfig, and system tray. I've tried and seen bugs regarding ar9285 from at least Lucid, but it seems that nothing is being fixed upstream. ** Tags added: raring -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947697 Title: Atheros AR9285 Wireless on Ubuntu 12.04 is slow, unstable and has a weak signal.
