SL is fully working except one annoying ethernet problem.
Then I try to download something, or just get more packets for example turn on skype ethernet goes away and just after ifconfig en0 down/up it starts working again.
I tried built-in and PCI network cards, but I get same result
Maybe someone has same problem and solution to it?
My MB:
PCI Ethernet card: RLT8139
Then I try PCI card problem is a little bit diferent, because IP's goes away.
