I had fedora core 3 and I am using MA111 adapter. It was happily working when I followed the method explained in

The problem is that I have now upgraded to core 4 and am in a big mess. It gives the exact same error as shown in your message. my kernel is kernel-2.6.11-1.1369_FC4 . I have checked my router and it shows that both the adapter and router are communicating but somehow I can't connect to internet. I dont know where the problem is! Any ideas or suggestions? Is it a bug?

I have gone to this mesg and I think the problem got corrected in his case because he upgraded his dhcp-client. Incidently there is an upgrade for the same posted at

But I am yet to check that for myself because I have not installed the updates for dhcp yet.

I hope someone will provide a better explanation or solution to this weird problem!
