Orbi 2.4GHz Channel Width Stuck On 40Mhz

I have my Orbi Router set to only use 20MHz Width on the 2.4GHz band (channel 1). However, using WiFi Scanner, it shows my Orbi wireless connection is using a 40MHz Width. I would like to only use the...

    I’ve never had the “Enable 20/40 MHz Coexistence” box checked. I assumed if I had that box checked, then it would use the 40 MHz Width on 2.4 GHz, which is what I’m trying to avoid. I particularly wanted to keep the Width at 20 MHz because multiple neighbors are using 2.4 GHz channels that are overlapping on each of the three main channels (1, 6, 11). My assumption (from using other routers in the past is that if the box is not checked then the channel should stay within the 20 MHz Width, and if the “Enable 20/40 MHz Coexistence” box is checked, then that allows the router to take up 40 MHz Width automatically.

    I think you have this exactly backwards. Think of the box as “Enable peaceful coexistence with neighbors.”
