Hi, I'm having a strange problem. On my 100Mb network (100Mb switch, Cat5 cabling, etc.), my network card keeps falling from 100Mb during system boot, to 10Mb after networking stuff is loaded in Debian Unstable. During bootup, everything is fine. Then suddenly, when the networking code is loaded, the 10Mb led shows up on the network card, and the connection falls back.
Do you know where I should start to look for problems? I've tried switching network cards, but that hasn't solved a thing. Also tried different PCI ports. No go. Any ideas? What should I start looking for? My other computers have absolutely no problem (running stable). Thanks in advance. Jason.
