Wlan connected but no internet

[mromblad]

Ubuntu 9.04 Jaunty

so I get my Wlan to connect to router. It pings the router and can even find other computers on home network.

The issue is that the internet will not work. All the other computers have working internet, all windows boxes, and the windows partition of this computer has working internet.

I cannot connect to thunderbird, pidgin, or firefox. I also cannot download packages.

Again, The computer IS connected to router (I can ping the router and other computers on network). The computer IS NOT receiving any internet. All the other computers on same network DO have internet.

How do I fix this to get internet?

Thank you

Case Closed.

Make sure when setting it up, you don't accidentally check the box saying that only allow inter-network communications. It kind of blocks the internet :P
