How to restore interface's default MAC address

RouterOS General
1

Hello,

I happen to have duplicate MAC addresses in one network I’m troubleshooting right now, and I suspect people just did ‘export’ in one device and pasted that into another one. I don’t want to invent other MAC addresses nor use locally administered addresses, so please tell me the way to restore MAC that’s built into hardware.

Thanks.

Thanks… I apparently haven’t done my homework…

Hi guys, I’ve found two RBs with same MAC address on wlan, maybe a wrong cloning operation.
Is there a way to get factory default mac address without reseting wlan configuration?
Thanks.

Not that I am aware of, but you can export the configuration

/interface wireless export

Reset the wireless configuration and then import it.

Guess maybe it’s the far end of a point to point link and this is not doable without losing access?

Another way to restore a wlan (wlan1 or wlan2) mac address is this:
Note - This only works on a Mikrotik if you have access to it when the wireless if disconnected !!!

  • 1st , make a backup
  • 2nd , using Winbox , in wireless click on [ Reset Configuration]
  • 3rd , now go into wireless and copy the wireless mac address
  • 4th , restore the backup
  • 5th , paste in the correct wlan mac address
  • 6th , make a backup (of your correct configuration)
