iBook G3 Detects Wireless but I Can't Surf the Web

[tuebinger]

I have an iBook G3 running Ubuntu 7.04. It detects my Netgear wireless router no problem but I can't surf the web. I'm getting a strong signal so I know my card is working and everything but I can't get the Internet. All the other computers and devices in the house can access the wireless network fine. Does anybody know what might be wrong? Am I forgetting something?

I had a problem like this, and I had to manually enter DNS servers to solve it. That might work...
