Cannot get wireless network up in Ubuntu 8.10

I have just installed Ubuntu 8.10 on an older laptop that I had been running Windows XP Professional on. I do not have any problem connecting to my router on a wired ethernet connection but I cannot get a wireless connection. I have a internal Intel PRO/Wireless LAN 2100 3B Mini PCI Adapter as well as a Linksys WPC54GS card (Broadcom BCM4306 802.11b/g Wireless LAN Controller). I have tried reading various posts regarding using ndiswrapper, network manger etc. I believe I installed the driver correctly as it shows up in hardware testing. Here is the text of what appears using the sudo lshw -C network command:
rick@rick-laptop:~$ sudo lshw -c network

When I click on the Network Manager icon it shows both wireless cards but they are grayed out and they both show "wireless is disabled".

I am new to Linux/Ubuntu but I am computer literate. I just don't seem to be able to figure out what I am doing wrong. Any help would be appreciated.
