Model: Archer C6  
Hardware Version: V2
Firmware Version: 1.3.6 Build 20200902 rel.65591

Hi,

my Archer C6 is set to 40 MHz channel width in the 5 GHz Wi-Fi settings to avoid interference with neighbor Wi-Fis. I have noticed that from time to time it starts to use 80 MHz, although the configuration still shows 40. When this happens the quality of the Wi-Fi connection drops significantly. While the connected devices show full radio signal, the data transmission performance shows significant problems. In this case I can only change back to 40 MHz if I set first 20 MHz and then set 40 again. Enabling and disabling the wireless radio does not solve the problem either as the router starts to use the 80 MHz channel again, with the configuration still being set to 40. Is this a know issue?

Thanks
