Try "modprobe rt_8139too media=0". If I parse the code correctly ATM, that should make it switch to 10Mbps/half-duplex. Hmm, something is fishy here anyway. Looks like we are currently locked to FD/100Mps due to "media" being initialised with -1. Ah, that's due to Fabian's changes for media selection: http://rtnet.svn.sourceforge.net/viewvc/rtnet/trunk/rtnet/drivers/rt_8139too.c?r1=983&r2=1014 Fabian, can we choose a different default for "media" to get auto-negotiation working? Otherwise, more documentation work would be required here to deal with non-100Mps and non-FD cases more user-friendly. Jan
