I'm having this problem with my network card on fedora core 1, And I don't know what to do to fix it.

This is a dual boot system with XP and fedora (which was a reformat of RH9 on a second drive) XP and RH9 work (and worked) just fine. But since i reformatted rh9 with fedora my LAN connection is so slow it takes forever to tranfer 700 megs over the lan from it. (i'd say less than 10 percent of the old speeds)

dmesg says this during initialization;

I havn't noticed messages saying anything about it....

I've been looking around on the internet and all I can find is these cards not working at all with kuzdo on older beta builds of fedora. I really don't know all that much about trying to fix something like this on linux if it 'doesn't just work'... Where should I start looking? Or what should I do? On the hub it's connected to, it shows the 100M light.
