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?

For example I can ftp put at about 2.7-3.0 > MB/sec but only ftp get the same file at about 40-120 KB/sec. and that was manually > setting ifconfig for 100baseTX and full-duplex.
