ok, i check the metal clasp things you pointed out and they're on there correctly. also put the mb on a slab of newspaper and tried to see if it worked, and got nothing.
so i started over from scratch, uninstalled the drivers, restarted the comp, installed, and restarted again. i plugged in the rj45 from the cable modem turned it on, and i got the lights next to the rj socket to flash. that didn't happen before. i also notice that the ethernet adaptor is in the device manager, but it wasn't there the first time i installed the driver.
any ideas?
