why won't this network card connect at 100Mbps?
 

10 is too slow, the card used to do 100mbps, but now it's stuck at 10, what can I do?

bump
this is with xp, and it's a regular 10/100 card

A bad network cable can do that to you.

There can be lots of reasons:

-bad cable
-bad switch or hub
-another computer in the network only connecting at 10 Mbps

Taken that your configuration in XP didn't change you can try replacing those things and see what happens.

everything else connects at 100mps, it's the card, since I triedto force it into 100Mbpsand it sll connects at 10, going to geta new one tomorrow

are all the other devices pluged into the same switch/hub?

try changing cords and ports in your switch/hub.
