Fedora Users — FC6 ipw3945 on Dell D820 not working. What's the best way?

SO I bought this brand new Dell Latitude D820. I've been trying to geta fully working Linux install on it for weeks. I tried F7, but the newsuspend mechanism doesn't work on this laptop, and there's no way aroundit, so I installed FC6. But with FC6, I can't get the ipw3945 wirelessworking. I can't catch a break!

There seems to be several ways: the iwl* packages, the ipw* packages,with or without Network Manager...


So scanning the internets and this list, this is what I have now:

"iwconfig eth1" and "iwlist eth1 scanning" both produce good-lookingresults, but the WiFi light is flashing very quickly, and "ifconfig eth1up" doesn't get an IP address, nor does "dhclient eth1", which justkeeps trying.



So what am I doing wrong?
What does the fast blinking WiFi lite mean?
What's the difference between the iwp* packages and the iwl* packages?

Thanks. I hope I included enough information. I'm pretty desperate atthis point. This is an expensive laptop!
