problem with spaming out Mac adresses

[crisun]

I have a ASUS Motherboard A7N8X Deluxe, Ver 2.0 ,Bios C1005
and have installed
NForce2 all in one version 1.16 driver for WinXP
The problem I have if I use the Nvidia Lan(integrated) then My ISP
close my port on their switch
becaus the Nvidia spams out MAC addres, says my ISP to me when I call them ,the have some limit of 20 mac addreses then the switch auto close the port to my home!

but some how my nvidia network card(integrated) spams out diffrent mac addreses

but the 3com(integrated) on the motherboard works fine ,no spaming out mac addreses then.

Now I wounder do any one else have this problem ?
or are my motherboard defect ?

I know someone who has Nvidia on board LAN also, What was odd is I found no actual MAC adress, Hmmm but I would not see why your switch would act that way.

I would say buy a router, or a new network card. When I was in Cisco Networking, the instructor seemed fond of the Netgear FA311 NIC's, he gave me one and I have not had a problom with it yet.

A NIC has only 1 MAC address. Do an ipconfig /all and it will be the hardware address. If it is broacasting/ARPing more than one MAC address it is defective.
