Using the 5 Ghz radio in accesspoint mode (mode ap) and client mode (mode sta) at the same time doesnt work.
Only client mode works.
No error messages will be generated.
With version V17.01.4 all is fine (same configuration).
Does this setup work for you on another platform? (not QCA9880)
Sorry, i have only this router (Archer C7 V2), but with stable Version v17.1.04 all is working fine. After upgrade, no AP Mode in 5 Ghz is available.
What exactly "does not work"?
The Archer C7 have two radios, one 2,4 Ghz and one 5 Ghz. I have a client connection (5ghz) to my main router as mode sta. Also i have defined a 5 ghz radio with the same channel, different ssid as mode ap. After upgrading to trunk, the ap (5Ghz) is not working anymore. The 5 Ghz sta connection works every time. Also the 2.4 ghz is ap ist working all the time, it doesnt matter which version of LEDE i use.
