Adding 2.4 channel 11 on NightHawk model R6700v3

[kikipyz]

I have a nighthawk Model R6700v3 operating at 5 GHz. I need to ad a 2.4 GHz channel 11 to connect my new HP Desk Jet 3755 printer. How do I do that.

The R6700 is a dual band router. It should already have 2.4ghz enabled. 

you can log in through the browser and check it. 

You might just be using smart connect that combines the 2.4ghz/5ghz into 1 ssid

You can change the channel to 11 with Smart Connect enabled.

Go to http://routerlogin.net or http://192.168.1.1 with a browser. See if you have Smart Connect enabled. If so, disable it. Then set the channel you want for the 2.4 GHz band.
