I upgraded an X750 (V1) to 3.203-0701 and the 2.4Ghz Wifi is no longer working. 5Ghz Wifi works fine. The 2.4Ghz Wifi is enabled in the UI. Turning it on/off has no effect, reboot doesn’t change anything either. Everything thinks it’s working but it’s not actually broadcasting beacons (test with multiple devices).

I don’t know whether the firmware loading errors are normal, the last message also looks suspicious.
