Issue with Win7 PC
We just recieved a shipment of Win 7 PC. While installing them, we noticed that the port the PC were connected to are error disabling... Allowing the port to except 2 MAC allowed the PC to work, but the second MAC happens to be the Routers MAC address... When this MAC appears on the port we lose connectivity to that network...

Yes, the PC has two mac's, the issue is that the 2nd MAC is the ROUTERs MAC and it is acting like the default gateway...
how come there are 2 macs with the same numbers? impossible!
you can download mac changer and change the 2nd mac to something else

Not just one PC, there are few... The ones that show this take the ROUTERS MAC address, witch is the Default Gateway...
i once faced this issue, normal PC and one mac. our neighours are connected to our router and once we faced internet curruption. found out that they installed 4-port switch that cause this issue (IP issue).
if you have installed any devices lately, in which this problem appears after, remove them and try. you have to remember which date this was working .
