If you copy a config from one CPE into another, the wireless MAC address may also go with it. The MAC address of the wireless interface can actually be changed via winbox or the CLI.
Or try to pop a new terminal window and use this:
> interface wireless print
Flags: X - disabled, R - running
0 R name="r5h-1" mtu=1500 mac-address=00:0C:42:60:F3:C7 arp=enabled
interface-type=Atheros AR5413 mode=station-wds
If the MAC addresses of the wireless cards are the same but the ethernet MAC's are different, you have copied the wireless MAC into another radio unknowingly. Easy enough to fix but you have to know what the proper MAC should be. It should be printed on the card itself but then you have to go replace the CPE, unless you keep records of which radio card goes into which RouterBoard.
To change the MAC address via Winbox, just select the MAC Address field and enter the correct address.
To change via CLI, use:
> int wireless set 0 mac-address=XX:XX:XX:XX:XX:XX
where XX:XX:XX:XX:XX:XX is the correct MAC address.
Note that if you are using MAC addresses for authentication, you will have to change your entry for that user in your Access List/User Manager/Radius server.
