NEW Arcadyan TMO-G4AR can't split bands
I am trying to lock my WiFioutput to only the 2.4 Ghz band and turn off the 5.0 Ghz band. I see where to select this in the App, where it gives three options: Automatic, 2.4 and 5.0. I select 2.4, it confirms my selection, and goes offline 90 seconds and says the change was successful. But when I look at my WiFi output, it still shows it as Automatic with both bands selected. It won't shut of the 5.0 band. Problem is, some of the devices on the far side of the house like ROKU which work on both bands will lock on to the 5.0 which barely has a signal and will ignore the stronger but slower 2.4 signal. I need to shut of the 5.0 signal completely so only the 2.4 signal will work, and this new gateway will not do that. My old Arcadyan gateway did this just fine. I even tried creating a second WiFi network, but that did the same thing.
Wifi extenders disconnect from 5G gateway
I own 2 different wifi extenders, a TP-Link AC1900 (RE550) and a NETGEAREX2800. Both werked flawlessly with my Starlink router and with my Omada router when Starlink was in bypass mode. However, immediately upon starting usage of my new 5G T-Mobile gateway, the extenders periodically lose connection with the internet. Sometimes, when I connect to an extender, there is a 5 second delay and then the internet somehow comes on. Other times, it takes over aminute or two. This is unacceptable as I have smart devices dependent on these extenders and they regularly lose connection with the internet. Since this issue only started with the T-Mobile gateway I can only conclude it's a T-Mobile issue. Anyone have any thoughts before I return my gateway and cancel my test drive service?
Adding a RJ45 wired extender
(1) Is it possible to connect a RJ45 wired extender to the T-mobile gateway and run to the lower floor. Our ceilings have a old heated mesh (disabled) that prevents the signal to go from floor to floor. (2) Does the T-mobile gateway port send power thru RJ45? I would like to add the following UniFi U6 (see link) if it will work. https://techspecs.ui.com/unifi/wifi/u6-enterprise Thank you, Jerry
