WRT3200ACM + 21.02.0-rc4: multiple Wifis on a single radio?

[alex77]

My configuration:
OpenWrt 21.02.0-rc4 r16256-2d5ee43dc6
Linksys WRT3200ACM

On previous Openwrt versions (e.g. 19.7.7) I could operate several Wifis on a single radio. Now I upgraded to 21.02.0-rc4 and it is not possible to operate more than a single Wifi on a radio.

I tried to get two Wifis (OpenWrt, test) running on radio1, but radio1 states "Device is not active".

As soon as I disable one of the two Wifis (it does not matter which one), so that only one Wifi is active, radio1 starts to operate correctly.

Whenever I enable the second Wifi again, radio1 falls back to "Wireless is disabled". Restarting radio1 or even restarting the router does not help. I tried on 21.02.0-rc1, 21.02.0-rc2, 21.02.0-rc3, 21.02.0-rc4, without success.

Any help to get more than one Wifi running on a single radio would be highly appreciated.

In your config you set a separate MAC for one of the radio1 SSIDs, but not for both. Have your tested the config when treating both SSIDs similarly? (Either no change for both or specific MAC for both)

[alex77]

Thanks to hnyman for the advice regarding the MACs. I deleted all lines containing "option macaddr" from /etc/config/wireless and now it works like a charm

I do not really know, where the "option macaddr" lines stem from. I did not edit /etc/config/wireless manually before, so the lines must have been created by Luci. But now, having deleted all "option macaddr" lines manually, I could even add a third Wifi sucessfully.

Nevertheless, MACs/BSSIDs are assigned to each of the SSIDs/Wifis, but are not written to /etc/config/wireless anymore.

So, Wifis work as in OpenWrt 19.7.x and before. Great!

This line deletion fix solved my problem too!
Another big Thank you to hynman from here.
