For some reason the lspci -nn command didn't output very useful info. Try lspci -v.

Anyway, I've learned around the forums that Red Hat doesn't compile wireless drivers into their kernel by default, first off. Second, is there a reason you're using Red Hat? Especially a very old Red Hat? It's not a good general purpose or desktop distribution. You might want to consider Fedora, Red Hat's community project.

I still can't determine much. As you can see, there are a lot of "Unknown Device" messages. This is what happens when you install an old version of Linux on a newer computer.

You still haven't said why you want to use RHEL 4. There are newer versions of RHEL, and better yet, use CentOS 5.3 (RHEL clone) or Fedora. Either of these would be a much better option.
