This chip is supported in linux kernel by tulip driver. { 0x1317, 0x0985, PCI_ANY_ID, PCI_ANY_ID, 0, 0, COMET } And I compared the driver with 2.6 driver(Currently I am using 2.4.21 kernel), no related difference. So I thought this should not be a bug in this driver(maybe). When I ftp and telnet myself, it is ok. So the stack should be OK. So now I have no idea about the direction to find the problem. Please advice me. Best regards ======= 2004-03-31 15:45:00 Origianl message======= >On Wednesday 31 March 2004 00:02, Jack Liu wrote: >> >> We use ADMTek AN983B chip as our network chip.
