How dio I change my Modem from 5 to 2.4 GHZ
I recently purchased WIFI plugs that need no larger than a 2.4 GHZ WIFI signal to pair with my WIFI at home. My Modem is capable of Toggling back and forth from 5 to 2.4 . I do not have the option to set it at 2.4 only due to the Modem being controlled remotley by Comcast. How do I Set Modem to 2.4 GHZ only.
