MAC Address 00:00:00:00:00:00
I don't know why, but my network adapter on my laptop is set to 00:00:00:00:00:00. Can I change it to a valid MAC address? I thought the MAC address was programmed and unique to each network device from the factory. Any help will be appreciated."Men sleep peacefully in their beds at night because rough men stand ready to do violence on their behalf."

Which network adapter? Physical or virtual? For example, some virtual adapters like for certain virtualization software packages could have a zero'd MAC address. Virtual adapters can usually be manually configured via the related software.
I would find it rather odd for a phsyical network adapter to have a zero'd MAC address.
If you do want to try forcing a specific MAC address for a physical adapter, here ya' go:
Note, the linked instructions should work for most basic wired network adapters. As for wireless adapters and some specialized adapters, YMMV.Robert Richmond | Infinite perceptions. One reality.

Thanks, I put in a valid MAC address as your link described. It took it and I verified that windows had with a look at ipconfig. Still was unable to connect to my router. I finally just turned MAC address filtering off and repaired the connection in windows and it finally went back to the original MAC address and connected to the network. One I got the right MAC address acknowledge on the router, I entered it in the access list and turned MAC address filtering back on. Thanks for the help!"Men sleep peacefully in their beds at night because rough men stand ready to do violence on their behalf."

Oddly enough, I didn't have the option anywhere on mine to change the mac, through the device manager, through the registry, or direct flash.. It worked fine on my desk, and when I moved it into the office, it went all 0's. Strangely, back on my desk, it has it's mac address again..
Tested the wires, all are fine. This may actually be a result of the router/switch that the computer is plugged into... Beyond that, I couldn't imagine..
hope this helps someone else.
