Hello,
I also have an Intel NIC (fxp0). I must manually set it at 10BaseT/UTP
for it to work on the network. If its set at 100BaseTX, i can't ping
anything except for the interface itself. I've also had the problem with a
Linksys 10/100 NIC (dc0). This started happening sometime in the 4.x
series. I don't remember having any trouble in FreeBSD 3.x.
I know they both work at 100BaseTX, because I used both perfectly running
Windows ME.
Anyone having any solutions? Or is there a problem with something in the
4.x drivers?
Thanks
David
