I use DHCP reservation rather than static IP for convenience, and that relies on the MAC address of my computer.

I recently bridged my main adapter with my VirtualBox adapter. When things stopped working, I realized that the MAC address is now different. Is there some way to keep it the same every time I bridge or unbridge or do I need to reconfigure the router every time?

To change the MAC Address of a network adapter manually:

Open the Registry Editor:

Navigate to the folowing key:


Go through the numbered subkeys until you find one that matches your network adapter configuration. Modify the value named NetworkAddress to reflect the desired MAC address, but without hyphens/colons, if you want 00-B3-A0-03-00-1F, set the value to 00B3A003001F
