Can you swap the NIC with a different one?

[smokeybr]

I can... however i dont believe the NIC or PCI is the problem, i have now set up the same NIC,port,IP on a different router and its working so far however i do have a bunch of services turned off.

The reason i changed router was because i was using pfsense as a virtual machine
any thoughts ?

The "no carrier" message was making me think it was the NIC...however, it could be the cable or the port it is plugged in to.

it seems your guess was right, i had 2 different NIC however they were the same make and model both would result in the problems, when i finally used the onboard network port problem did not occur, it seems to have started after an ubuntu update.
The NIC is an intel PRO/100 MT Dual Port how would i go about checking support for it ?
