I am running 12.04 on an Asus EEEPC 1201n. Regularly, wifi connection is lost and there seems to be no way to get it back without a reboot. The same machine booted on WIN7 never fails.

I am at a loss, any ideas?

It sounds like the wireless driver may be your problem which may be fixed in each new release of the kernel so I would recommend trying Ubuntu 12.10 to see if that helps...

Also here is a link for the latest 3.7 version of the kernel for 12.10:
