1. You need to know which version of RTL 8139 chipset you have
(8139a/b/c/d).
2. if RTL 8139? adapter is onboard, then most likely this is APM
problem. Try disabling APM in BIOS for a good start. That worked fine
for my Asus VM266SE-LAN.
3. Try further tinkering in BIOS (change default IRQs).
4. If this does not help - the cheapest solution is another RTL8139 PCI
card with another chip version, around 10$ or so (onboard card should be
disabled, but if enabled it can happen that one x PCI RTL 8139 will
raise onboard brand RTL8139 card from the graveyard - voila you can have
them two or more to make something of your network).
cheers, JK
