My wireless stopped working and a tip here suggested checking my BIOS. In fact the wireless card was disabled.

In fact it is always disabled. I always press F10 to save and exit, but on the next boot, it is disabled again. Any idea why, and how to change it so it is always on be default like it used to be?

It's being disabled by Eeebuntu on shutdown/restart. As to why, by law you're not allowed to use wifi on planes in the US, so it's disabled (yes, it's here on the forums somewhere). I don't have the link handy, but there's a post about how to turn that off. You have to edit one of the eeepc scripts to stop it from happening. In /etc/init.d/eeepc-restore or something like that.
