Downloading Torrents locks up my Hackintosh

I went back to the way my networking was before, apparently the
Realtek driver works perfectly, except for one thing, it causes
problems with Torrents, and its an issue that even seams to affect
real Macs.

What happens is that you are downloading a Torrent, and out of the
blue your system locks up, and the only thing you can do is push and
hold down the power button and turn off the Hackintosh, from what
I have found it also affects the game WoW and anything that uses the
network intensely and that makes lots of network connections.

Until it gets fixed I may just have to deal with not having BonJour
working.
