I have a wireless router that assigns IPs using DHCP. My laptop (Acer Aspire 1 110L running Ubuntu 10.10) connects to the wireless network, but DNS is not working. I've tried to trouble shoot the problem following various tutorials on ubuntu help, but I'm stuck.

What should I do next to try to fix this problem?
