I finally get my SMC 2835w to work in Fedora 2.

it's rather easy to setup since the driver is in 2.6. All I have to do is download the firmware and place it at /usr/lib/hotplug/firmware (filename isl3890).

However, this card doesn't seem to be stable on Linux and I'm getting a lot of card reset.....

[Update] After more debugging, I found that reset my SMC barricade g router fixed the problem.... maybe it's a bug on the router, not the card?? But the connection never stay up for too long...
