i got a used hp mini yesterdayand installed ubuntu 12.10 today. like others, i cannot connect to a wireless network. "enable networking" is checked but no connection options appear. ethernet works. network settings only gives the options "wired" and "network proxy".
i tried the command "sudo lshs -c network" but get "command not found".
in addition, suddenly my arrow keys aren't working (pretty sure they were working yday though). so when i reboot, i can't choose ubuntu since i can't go down... (not sure if i should open a different thread for this). sorry, i rechecked. it's only the "up" and "down" arrows that don't work. it's hardware problem then?
