I am having trouble getting the Intel(R) PRO/1000 CT network adapter built into my motherboard (A Gigabyte GA-8KNXP version 1) to work with my Optus cable connection. Windows XP says that it is installed and working properly but every time I plug the cat 5 cable into it from my cable modem it was says “limited or no connectivity” But when I plug it into my second network card it works fine.
Anyone have any ideas on how I could possibly fix this?
I believe newer cable connections are MAC address filtered. You will have to call your ISP and have them reset the mac address they have on record before you can plug the modem into a new network card.
The 'limited or no connection' message could also indicate an ip conflict or the inability to get an ip address if dhcp is used. You might want to run a cmd windows and type 'ipconfig -all' to confirm your settings.
