I'm running Unbuntu 11.10 with the latest service packs, sharing an ether connection over wireless.

Everything works fine, up to the point that the client (a laptop) sleeps or otherwise disconnects. The wireless connection at that point no longer functions, not showing up when searching for the hotspot with the laptop. The only way to recover is to reboot the machine, or toggle the wireless share off/on.

I've double checked the wireless card has power management off.

Currently what I'm doing is keeping an Ipod plugged into the box 24/7 to keep the wireless connection up when the laptop disconnects.

I've searched the internet far and wide, found many issues with wireless problems after an ubuntu box itself sleeps, but nothing directly related to my problem.

Hoping someone has some idea of where to look and what to check. A girl needs her Ipod back!
