Hey, on my ds3l board with 8111b Realtek lan.. everything works 100 percent, but i usually have to unplug and replug my ethernet cord in for it to work, otherwise i get home ip error. any suggestions on what to do?

you can assign DHCP with manual IP adress.
you can use Realtek1000.kext (you´ll find it here)

Well, in the past that Kext has screwed my computer up, nor has it helped very much. I also think it isnt necessary for leopard.. my card should be working without anything. Ive Set DHCP to Manual before.. but there was no luck.
