Anyone using 22.x on 5G? How stable is it compared to 21.x?

This firmware works really well. It really helped with our framing issues on the AP. The only issue with it is you can’t upgrade from 22.0.1 to 22.0.2. Several SMs will not update and we had modulation issues because of the firmware mismatch. The solution is to revert back to and then go to 22.0.2.

Sorry to hear that you were having issues with upgrading from 22.0.1 to 22.0.2.
Were you upgrading using cnMaestro or CNUT? What was the error reported by the tool?
We would appreciate if you can provide any logs for us to debug this issue further.
You can email it to me at
