Nothing likes macs, or anyone might I add, was a post today about macs.
We know you don't like Macs or Vista, you don't have to announce it in a thread you aren't contributing to. As I was debating on whether to leave your post or not I thought I bet I can find a similar problem with a Windows box.

I did a bit of google searching and found this from this page (http://www.xlr8yourmac.com/OSX/os_x_network_cards.html).
Decided to try a D-Link DFE-530-TX. Installed the driver from the D-Link site that says it is for 10.1 and up. I got a warning about corrupt *.kext file or bad extension or something like (security warnings can be permissions related also, using the 'fix and use' option will correct permissions - however see the update in this (previous DLink 530 report that includes a link to realtek drivers) that when I re-booted. Re-booted a second time and got no warnings, set up the card in the network preferences and it has worked just fine for one whole day since then. I will let you know if I run into any problems. The card was $5 after a $10 mail in re-bate.

Part about Realtek (http://www.xlr8yourmac.com/OSX/os_x_network_cards.html#dlink)
Their link doesn't work, but I searched for that file name and ended up here (http://www.versiontracker.com/dyn/moreinfo/macosx/11459&mode=feedback).
Perhaps thats of some help.
