The machine is an old laptop with a pcmcia 10/100 network card but it seems that I'm not getting better than a 10Mbit connection. This number is based largely on observations copying large files to and from windows, I'm sure there's a better way to test this from BSD. I believe I've eliminated everything outside the network card by doing some tests with a crossover cable and checking the switch and cable. I believe I've eliminated problems inside the machine with various "time dd if= of=" tests. I think ifconfig -a is saying that the os thinks the card is 100Mbit: ed1: flags=8843 mtu 1500 inet 192.168.1.5 netmask 0xffffff00 broadcast 192.168.1.255 ether 00:a0:0c:40:32:a3 media: Ethernet autoselect (100baseTX ) status: active So my questions are: How do I check the network performance from within freebsd? What other tools can I use to check for network problems? How can I check the network card is configured and working correctly? Thanks for any help! Paul Boldra
