Hi there, something strange here: dmesg snipplet: eth0: RealTek RTL8139 Fast Ethernet at 0xd09a2f00, 00:00:b4:a6:d2:30, IRQ 9 eth0: Identified 8139 chip type 'RTL-8139A' eth0: Setting 100mbps full-duplex based on auto-negotiated partner ability 45e1. and then with mii-tool: eth0: 10 Mbit, half duplex, no link I got a xferspeed of approx. 4 Mbyte/s so it seems to be a bad 100mbps link....
