ar71xx: wifi sta/client mode fails with "Operation not supported"

[irimi]

ar71xx/ TPL 1043ND:
At least since -r31708 wifi sta mode always fails with "operation not supported", -r31650 is still fine , I guess problem could be caused by -r31689 ... -r31692 !??

Problem is confirmed by other user.

The problem is that the 'wan' interface already has an assigned ifname (eth0.2) that is not a bridge.

Either remove eth0.2 from wan, or create a new interface without ifname and use that for wifi.
