Duplicate Mac Address

[Deksastara]

When a network finds a duplicate mac address does it block it? I have two devices with the same mac address that worked for a day or two (never connected at the same time), but then they stopped recieving internet access. I tried clearing arp cache and releasing/renewing ipconfig on both computers. Anyone know how to resolve this issue?

Can two devices have same MAC address?

If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. ... Duplicate MAC Addresses separated by one or more routers is not a problem since the two devices won't see each other and will use the router to communicate. Sep 13, 2015

Do you know of a fix to this? I tried changing the mac address of one device, but the shared mac address still appears to be blocked.
