Earlier I installed the kernel update (from 3.5.0-21 to 3.5.0-22) in xubuntu 12.10 and my system stopped recognizing any networking (ran ifconfig via terminal and it only showed the loopback, no ethernet or wireless). I reverted to the old kernel (3.5.0-21) and it works again. Is there something I need to do to get networking working with the new kernel?
edit: Thanks to leef's suggestion to use lsmod, I compared the two and realized the proprietary drivers for both my ethernet controller and wireless adapter were removed by the kernel update. I reinstalled them and now everything works fine.
