There's an additional development here: blacklisting acer-wmi stops the constant disconection and reconnection but the wireless then runs very slow. Here is a link to another user's advice on this, with a different machine, Ubuntu 11:10 being the affected version, this Kernel 3.0 and above again: http://www.lamnk.com/blog/computer/fixing-ubuntu-11-10-oneiric-ocelot-wireless-problem-with-atheros-ar9285-and-ralink-rt3090/ On some machines this seemed to fix all the problems, on mine it left the wireless staying connected but almost uselessly slow, a problem that may have existed before but beenundetectable due to the constant disconnections. There are bugs filed against "ubuntu" for this blacklisting acer-wmi does not harm performance on 2.6 kernels on my netbook, so I left the blaxcklist in place
