IS it best to separate the 2.4 ghz and 5 ghz wifi channels?

I have a lot of smart home devices, light switches, cameras, Alexa, Tesla solar, etc. All use the 2.4 ghz wifi. When grandkids come over, with their wifi devices and games, my TV streaming slows. 

 

Would it be best to separate the 2.4 ghz and 5 ghz channels on the t-mobile home internet gateway, only allow guest and grandkids access to 2.4 and keep the 5 ghz for TV streaming and home computer?

 

 

  • I would also use the hybrid 2.4 and 5 GHz network which auto-selects the band and channel for each device as the primary network.  I don't know if there is a proper name for it; I call it the "default" network because that is how the gateways are configured out of the box.  A separate 2.4 GHz network, with lesser security if needed, can be added for older devices or ones that won't connect to the default network.

    Before I had the T-Mobile gateway, I used a Netgear Nighthawk 802.11ac router.  It had both 2.4 GHz and 5 GHz bands.  I set up connections for my TV to both.  Occasionally (maybe once a month), the TV would lose its connection to one and I'd have to go into its settings to switch to the other.  I have not had to do that in the year that I have had it connected to the default network on the T-Mobile gateway.

    I have not had any trouble with any of my devices in my home, except for the ancient desktop computer and printer which would not work with the WPA2/WPA3 + AES security on the default network; and they are so old, they don't recognize 5 GHz signals either.  I made a 2.4 GHz WPA/WPA2 + TKIP/AES network just for them.

    I have not seen a reason to add a dedicated 5 GHz network in my home.
