Home internet dropped to 4G

As it is, it's a normal little 1 story house no upstairs, and I'm not terribly far from the window. All my phones have good signal on thier own. And I'm in a good area, Dubuque Iowa, for solid signal whet emy house is. I figured maybe they were working on stuff. I'll call them in the morning if it's still 4g,and Also move it closer to the window... Just less convenient wiht ethernet cables and such lol. 

Well my phones all have 5g everywhere in the area, and city too. I had 5g on the wifi till this morning, so the last 2 weeks or so, but now the box says it's on 4g  I'm gonna try to mvo wit tomorrow anyways, close to a window. As for the phone app, it gave info on the signal status (I'm at work now) for 4g but 5g info was gone. Just - marks for each one. 

It sounds like that bedroom where the 5G does reach might be a location to check for service with. IF there is only a single location where the 5G signal is strong enough that is where I would start. If the signal is the n41 penetration into the structure may be poor. That is common for the higher bands.

On an iPhone with 5G you can dial *3001#12345#* and put it in what is called Field Test Mode. It will allow you to see the cellular information. It can be helpful. I bring up the info and screen shot the information when I am doing diagnosis. Knowing if there is a 5G signal helps. Knowing the PCI value, the physical cell identifier, allows the cell to be located via CellMapper.net which during setup and location of the gateway can be very helpful to know. It also helps establish proper expectations. If the tower is too far away or the other side of a large building or mountain it is going to be of little value. Trees, hills, buildings, trains, weather, other radios such as EMT or trucking can all add issues like noise or knock the signal down. Any obstructions in the Fresnel zone causes some signal degradation if it is beyond 20% as I recall. Clear line of sight is often rare.

So off wifi, my. Phone my wife's. Phone and my mom's phone get 5g. Occasionally my mom's actually gets the 5g U or whatever it's called, but only in the corner of her bedroom. So hopefully. I guess I'll call tech support of it doesn't fix here ina bit. 

You will probably need to contact support to try to get some clarification. If you have 5G cell phones see what they report. With Apple you can put the phone into field test mode and get some info. With an Android phone I would suggest an a network scanner application that also reports cellular signal metrics. You seem to have strong signal strength for 4G but the 5G is a bit of an unknown right now. 

If you only lost 30-30 then the 5G is probably not that strong. You can’t just gauge the signal strength on the LEDs on the gateway alone. That is a bit misleading as it is rather general and does not provide any differentiation between the 4G or 5G. Using the mobile application to see the cellular metrics for both signals is how you can tell more about the service.

So the 5G signal is down. Use the T-Mobile home internet mobile application and check the cellular information reported for 4G and 5G and post more details about your service. I will assume it is the Sagemcon gateway so using the mobile application for management is the only option. My guess is that T-Mobile is working on the tower/cellular equipment and that is the reason it is not seen.
