thank you Emily, sure Community cannot solve but maybe someone had same problem and found workaround or simply tell me if I did something wrong. Moreover I noticed that TG6442VF can set manually WiFi channel to be used, but channel available are only the ones 20 MHz bandwidth deputy. So if I want to fix a 80 MHz channel (e.g. 42 or 58) I cannot. What should I insert?

if I set bandwidth = 80 MHz then I can set manually the following channels: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124 128.

From WiFi specification, 80 MHz channels are the following: 42, 58, 106,122.

What should I choose? The only available channels that can be set are the ones that WiFi specifications define as 20 MHz bandwidths
