WLAN1/2 MAC Address Swapped



  • I noticed a minor issue with my WLAN MAC address after upgrading from 2.2.6 to 2.3.r.20160331.1411.

    Before and after the upgrade I have both WLAN1 and WLAN2 configured. I leave WLAN2 disabled most of the time but enable it for guest access on occasion. My WLAN1 configuration was generally intact (https://forum.pfsense.org/index.php?topic=109171.0) but it's now using a different mac address. WLAN1 and WLAN2 are multi-ssid from an AR5BXB112 AR9380 card installed in my pfSense box. I'm 99% sure I didn't do any MAC address override pre-upgrade. I did try the MAC Address control (spoofing) at some point to see if it was supported by my card but it didn't work. I see no reference to either of the WLAN MAC addresses in my config backups so again, I'm 99% sure the "MAC controls" field for both WLAN1 and WLAN2 was not specified, and I'm 100% sure there's nothing currently entered in the "MAC controls" field.

    I didn't take note of the mac addresses assigned to ath0 and ath0_wlan2 before upgrading, but I do know with certainty that the WLAN1 MAC changed during the upgrade because one of my wireless clients had the BSSID specified and refused to connect until I entered the new MAC on the client.

    Presumably ath0 is unchanged, while ath0_wlan1 and ath0_wlan2 swapped MAC addresses.

    Before:
    ath0_wlan1: e6:ce:8f:xx:xx:xx

    After:
    ath0: e4:ce:8f:xx:xx:xx
    ath0_wlan1: e4:ce:8f:xx:xx:xx
    ath0_wlan2: e6:ce:8f:xx:xx:xx

    Thanks for all the hard work!
