hi,
thanks for your replies and sorry for the delay.
i've found various drivers, config and diag tools for the card, played around with them but didn't manage to get rid of the MAC address problem.
Various tools have detected the card and one diag tool reported an error which may be caused by invalid mac address. the other tests of that tool passed.
i'll try the card in another computer... could my card be damaged somehow or are there tools for manipulating the mac address? i remember using such a tool on a RTL8029 PCI card for physically changing the mac address of the nic...
edit: what I'm trying to achieve is connect the pc to my network via tcp/ip to share files and folders (using windows)...
