RT-AC1900P - get wrong control channel on 2.4Ghz WiFi

[dieter]

When I choose channel 11, I actually get channel 7 (using WiFi Analyzer).
Tried rebooting, but that did not help. When I choose channel 1, I get channel 1.

On 5Ghz, things work OK.

Any thoughts?

If I select control channel 9, I actually get 7. But if I choose 3, I get 3.

Wide channels in use perhaps?

@dieter The "channel width" option in WiFi Analyzer is experimental and reports incorrectly. Try using Acrylic Wi-Fi Home on a PC instead for an accurate reading.

yep, and one should consider _not_ using WideChannels in the 2.4G anyways...

I works if I use on 2.4g 40Mhz, channel 9?
I did not work if router is set to 20/40Mhz... Should I use 20 or 40 MHz? What is the difference?
