Hey everyone,

I just setup the Tmobile router for their internet service.  It’s the tall gray router.  I was curious as to how you can switch between the 2.4 and 5 Ghz bands.  I tried accessing the web interface but it just times out.

I use both the 2.4 and 5Ghz SSIDs.  I just use different SSIDs for each.  Once all set, my laptop/cell phone will see both SSIDs and I can connect to either.  If you have timeout issues connecting to the GUI, either the embedded server (in the router) is hung or maybe the SSID flipped back to default.  Both of which I see all the time.  Or, to get to the web interface without wifi, just connect your laptop directly to the router via a ethernet cable. Once you setup the wifi again, you should be able to connect via wifi.  BTW:  if you start seeing weird behavior, unable to access the web interface, just powerdown the router (press button).  Once back up, check your cell/laptop SSID network to see what the router is broadcasting.  You may need to use default SSID/Key.

192.168.12.1 is the web address

It’s setup and configured as a Tri-band router and supports WiFi6 and mesh.  Take it out of auto channel selection and use the channels that work for you if you need to.  IF you use it in tri-band mode, Roku’s, your phones and most devices including WiFi6 capability will handshake and switch between the 3 bands seamlessly.  The gateway will also load level between the 5GHz low band and the 5GHz high band automatically. Be aware that the auto channel selection picks DFS channels for the 5GHz bands and ROKU's won't connect to those.

The tri-band works on having SSID1, SSID5 and SSID9 all configured to the same SSID name and encryption mode.  

SSID1 is the 2.4GHz

SSID5 is 5GHz low band

SSID9 is 5GHz high band

Use WPA2/WPA3 and AES for all 3 to avoid any issues with the auto band switching.

Note that if you use the other SSID's 2-4, 6-8, 10-12 you end up with a bunch of SSID's on the same channels and there is no guest mode or SSID isolation so pretty useless. You can turn off the individual radios but that requires every SSID to be set to enable SSID and broadcast SSID to off, all 12.

If you don't want to use it this way then pick unique SSID names for each band and connect your devices uniquely to that SSID so they don't automatically switch and potentially drop connections and hang. None of my connected devices have issues with the auto switching but yours might.
