After setting up the Quantum Gateway, I made some changes to its Wi-Fi channel settings. After using the WiFiAnalyser app, I determined that the best channel for my router would be 6 on 2.4G and 36 on 5.0G. The router initally chose 6 on Auto mode, but I wanted to make sure it remained on 6, so I changed it manually. After the change, I noticed that the router had changed its channel width on 2.4G from 20 to 40. When I returned it to Auto it returned to 20. On the 5.0G network, the channel width remains 80 regardless of Auto or manual, so this question mainly pertains to the 2.4G frequency band. Is there a way to lock the channel on 6 without broadcasting a double-wide frequency?
