Cannot set WIFI control channel

[picasso]

Hi there,

I have an RT-N66U and just installed the newest Merlin version 3.0.0.4.374.39.

I hoped that this would fix a problem I also had with the previous version: I cannot modify the control channel of my Wifi.

Whatever I select (1, 5, 12, Auto) the router always uses channel 6, although it is quite crowded. 1 or 12 would be a better choice.

Is this a bug or am I doing something wrong (see photo) ?

Known issue. Set bandwidth to 20 MHz, the issue occurs when the router downgrades from 40 to 20 MHz, it switches back to the default channel (6).
