My Realtek network cards do not recognize that and always start in 100Mbps / full-duplex mode. So no packets are transmitted. Is there any possibility to bring the real-time network adapter up in 10Mbps / half-duplex mode? I had a look at rt_8139too.c and found the parameter description: MODULE_PARM_DESC(media, "8139too: Bits 4+9: force full duplex, bit 5: 100Mbps"); But I am not quite shure what to do with that...Try "modprobe rt_8139too media=0". If I parse the code correctly ATM, that should make it switch to 10Mbps/half-duplex.
I'll give that a try, but can't test it with my hub at the moment.Would it also be possible to write in rtnet.conf: RT_DRIVER_OPTIONS="cards=1,0,0,0 media=0"?
modprobe is unable to find my rt_8139too module. Jan
