I am experiencing a bug which causes my Atheros wireless driver to error out and drop my connection, requiring a reboot to re-connect.
I am surprised that I haven't heard more complaints about this issue which has plagued my hardware since ubuntu's later stable releases of kernel 2.6.28 and continuing into linux=3.0.0-14-generic with ubuntu 11.04. This is triggering at random times, usually once or twice a day, seems to be slightly more likely during heavy network use This is not happening as a result of suspend/resume. It is not fixed by installing compat-wireless, neither by adding "options ath9k nohwcrypt=1" to /etc/modprobe.d/ath9k.conf, nor by setting power management options with iwconfig There are several bugs on launchpad which describe similar problems, such as this one: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/622265 but I would welcome suggestions of other bugs that may be more pertinent.
