LAN port diagnose

Traveler

Senior member
My new board's LAN port doesn't seem to receive any signal on WinXP.

Is there any software can diagnose the physical port?
Or there is some kind of tool to diagnose physical network port, but I forgot what it's called...
 
Does it show up in Device Manager? If not, make sure the onboard LAN has not been disabled in the BIOS. Rare perhaps, but I've seen it happen even with brand new systems.
 
Yes, it does show up in Device Manager. It even shows up at the lower right-hand corner when I plug in the line.
When I click on it, it shows up network connection status. But on Activity, only Sent has Bytes showing, Received is 0. That's how I know it's not receiving.
 
I just found this: the onboard LAN port is actually fine. I hook it up on my dsl modem, and it works fine. But for some reason, it just can't connect when I hook it to router, unlike the other onboard LAN port I have. To make connection to the router, I have to insert a PCI LAN card to make connection!
And I haven't found the reason.

By the way, the one that cant hook up to my router is SOYO SY -P4I865PE Plus Dragon 2 V1.0
and the one works perfectly is ASUS P4SDX.
