openSUSE 12.3 with Network Manager

NOTE: The same behaviour occurs for eth0, but it's primarily wlan0 I'm concerned with.

Whenever I restart or switch wifi networks, DNS resolution seems to be the issue. nm-tool shows I have a valid IP and my router's address for DNS, but if I try to access anything by domain name, it fails. I successfully can run ping 8.8.8.8 (google's DNS) just to make sure I'm getting to the outside world. The only thing that seems to bring me back online is opening a terminal, logging in as root and running dhclient.

Anyone have any ideas what I should check to figure out why NetworkManager isn't working as expected?

Do you have the wireless network configured to use DHCP on both AP and computer sides? –  peterph Apr 10 '13 at 22:39
