Is this really a half duplex 10mbit > port or is it meant to be full duplex? Cable is good, it was working just fine before on my 3com 905b, I did plug it into my tester to be sure though. Motherboard has a tester that should alert me as well. It's built into the bios. The nic port is full duplex. Plugged directly into a westell wirespeed 2100 (ADSL Modem). Nic is onboard, Asus P5DL2. I have the latest bios flashed from the website. As I said before its pretty random. I guess it does happen more often under load though. Usually downloading a large iso is a quick way to bring it down. It's not a sure thing though. If there is any type of debugging I can do to provide more info would be happy to do so. Thanks.
