Ubuntu 9.04: IBM/Lenovo ThinkPad R51e Networking Issue

I have a ThinkPad R51e with a Broadcom NetXtreme Fast Ethernet interface and a 11b/g Wireless LAN PCI Adapter and neither one seem to be fully recognized by Ubuntu. The ethernet port works somewhat, but I cannot connect to the Internet, or even my modem, however I can connect to my router.

Also, I can't seem to change the address on the interface for some reason. I can make a new connection, but it is never applied. I'm just stuck with the same 192.168.1.107 /24 address when I look at the network utility in the admin menu.

When I boot into Windows, I can get connected with no issues, regardless of which interface I use.

Any suggestions/things I should know?

I've also posted this on the Ubuntu Forums, but I usually get faster replies here.

Nevermind, the problem seemed to fix itself.

Could you post what you did to fix it so that others with the same problem can have the solution?

Isn't linux brilliant.... it fixes itself!

I disabled Firestarter because it was blocking everything, plus my router already has/acts as a firewall. Sorry for the extra-late reply, btw.
