I have a DLINK 10/100 PCMCIA card (DFE-650TX) in my laptop (I installed the last version of PCMCIA package: 3.1.20) and a Realtek 8139 PCI 10/100 card in my desktop. The adapters are linked by a crossover cable with RJ-45 plugs. DFE-650TX is setted up to autonegociation (it is the only one option; when I try ifport eth0 100baseT, a error message is displayed) and I can set up the link mode at Realtek 8139 with mii-diag program. I got only 8 Mbits/s at a ftp test by copying a 14Mbytes archive. Does anyone have suggestions???
Thanks! Carlos Menezes.
