    80 MHz width is on by default regardless which channel you use. If you want to force 160 MHz width, you need to use a DFS channel, usually between 52 and 140. As I mentioned, your wifi device needs to support 160 MHz width too or else it won't work

  • Netgear calls MHz channel width 'mode' (http://duckware.com/wifi#netgearmode)

     

    But in almost all cases, you want to keep it on 80 MHz.  Clients will just connect at the maximum channel width they can.  If that is 80 MHz, great.  But if that is 20/40, clients will connect at 20/40 just fine in 5 GHz (using 802.11n).

     

    I need to research this more, but I believe if you turn off 80 MHz mode, you are actually turning *off* 802.11ac support and turning the router into a 802.11n (dual band) router.

     

    For 160, go to Advanced / Advanced Setup / Wireless Settings and check 'Enable HT160'.  Not sure what happens after that, but that will get you started.

      For the 2.4 GHz band you can enable 40 MHz width by going to Advanced -> Setup -> Wireless Setup and uncheck the "Enable 20/40 MHz Coexistence" box. This will force it to use 40 MHz width. This is generally not recommended if you have many other networks that operate at 20 MHz in your area

       

      For the 5 GHz band, you can force 160 MHz width by going to Advanced -> Advanced Setup -> Wireless Setup
