I've got an N810 running OS2008, and occasionally (seemingly randomly), when I'm connecting to WiFi, I'll connect but not be able to resolve hostnames to addresses. I can ping numbers fine, but not names.

It looks like when things work fine, a file called /tmp/resolv.conf.wlan0 has the information that I'd usually expect to see in /etc/resolv.conf. When things don't work, the file in /tmp is empty (the file in /etc never seems to change). When things don't work, I have to power cycle the tablet to get things working again.

It's a terribly frustrating problem, any clues on what's going on or how to fix it?
