I noticed that Cpe does not follow Ap channel width , and has to be set manual on client cpe
( to allow the cpe to follow Ap 40/80Mhz Ce / eC .. )

Notched on:
Running 6.37.1 / using Nv2

It would be very convenient / more clear if this would a default "auto" setting in Client-mode i think.

I agree. This would be very useful.
