5G Home internet keeps dropping!

I have had the same problem. Good reliability for the first month or so and then started dropping out for an hour or two at a time. A week or so ago it dropped out and did not return. We were gone for the last month or so with our motor home. I’d call tech support and all they could offer was to rest the gateway which obviously I couldn’t do when not home, We returned home a couple of days ago and I promptly called Cox to reinstate our internet service, I then called T-mobile to cancel my internet with them. They asked why and I explained that I needed reliable service for my thermostats, security cameras, etc when we are traveling. After I said that they said no problem and proceeded to process the cancellation and sent me a return label for the gateway. The fact that they made no effort to convince me to stay makes me believe that they know their service is unreliable and there is nothing they can do about it.

My impression is that cellphone  data does trump home internet data, and that may explain why, at least here, the drop outs mainly seem to occur during rush hours. Still very annoying and IMO this service is only usable for non-critical apps or as a backup, which is how I use it here when my business-class Comcast goes on the fritz.

I signed up and requested 3 gateways. I got NOKIAS  ( labeled refurbished) One at my main home just was not going to cut it with 2 bars and 7MBPS. Another at a home 30 miles away is pushing 550-600 as I can see the tower. Perfect. The other one 200 miles away at another home was awesome from install to about 3 weeks in and was also pushing 5 bars and 650-700MBPS . I have cameras, smart lights, thermostat, etc and it just started dropping off intermittently. data usage is low, and I suspect a bad unit, A new (refurbished  one) was shipped and I will install in a couple days. I just hope it lasts as I only get there 2 X /mo  but I run all my systems on it. ON a chat I was told I was getting throttled, but  for what??? 24 Gigs a month at a place I don't live at? That was not in my plan and they clarified that.  Hey, I just want consistent good service. I've heard that the NOKIAS have issues, as well as the ARKADYIANS, so what is the resolve? I was also told that broadband is controlled by my rep, and once it is full, no more  gateways would be available at the tower. But does Cell phone data  trump the gateways?

I just cant get a straight answer. I’m happy so far but if a salesperson, on a recorded line says something, it needs to be true. I love the company after 32 years with ATT, but just give me what you say you are going to give me.

Mine is the Nok 5g21.  It started to do what everybody complained:  Dropping connection-reboot-work for some time and do it again.

Did the following:  Switch it OFF, extract the SIM card (it had a nice fingerprint over the “gold” contacts, dark of dirt!).  Cleaned it with a rubber eraser and rubbing alcohol, Reset the unit with the small reset button.  Turned ON.  After two days now and it has not failed.

Not to say problem solved as time will tell.  But, what kind of people are installing SIM cards on these units?  Not to divert from the main issue, but anybody knows why T-Mobile restricts access to Port 21  ??  My gateway and cell phone can’t, but Verizon does work.

The cellular wireless 5G solution is not a simple solution that will work for everyone. Transmitting through the airwaves will always have challenges. A fixed wired solution that is a mature technology is going to be more reliable. Maybe one day cellular technology will evolve to be a more stable and robust delivery system but it does have a way to go yet. 
I think it is important to remember that the objective cellular vendors have is to reduce overhead costs and boost the revenue returns for investors. In some markets the solution is working but but as expected not for ALL users. If they focus primarily on the bottom line and don’t attend to the problems it will continue to be inferior. End to end details make great companies. Execution does matter. 

Ours does the same thing, when I called about it, the lady said they were updating and that it would never happen again...needless to say it's still happening

I switched back to cable two days ago.

Now I can rest and not worry about Zoom calls dropping, my VOIP not completing and be able to watch streaming videos without a gateway reboot interruption.

I am curious if any one is lucky to be in area that has Verizion FWA to see if that service if more reliable.

Just called Customer Service for similar issues:  1) Home Internet drops tower connection randomly; and, 2) The iOS Internet app does not connect to my gateway.

Here are the answers I just received from Customer Service.

Regarding the dropped connections:  T-Mobile’s internet service is not a secure wired connection like competitors.  So a good connection depends on alot of factors.  Translation: T-mobile is not as reliable!  If you want reliability, get a wired connection.

Regarding the iOS app: That is a known issue.  They have no target date to resolve.  Find someone with an Android device and use that.  Translation: T-mobile does not have the technical skill set (internal or external) to fix an app that provides extremely basic functionality.

Sounds like Tmobile adopted an interesting business model.

I cannot argue with that. I am so glad my Nokia still has the web GUI for management. The mobile application is a poor solution for gateway management. 

This morning, I have 4 bars.

I hope this means my loss of Internet problem is finally fixed.

Agreed, rotating the gateway does make a difference.  Arcadyan KVD21 has a display with buttons on one side.  Initially I had the display opposite (away) from the window so it’s easy to read.  Now, I have it turned almost 90 degrees to the right.  I also put it on top of a box, on the table, to raise it up higher in the window, with blackout curtains to protect it from the sun.  I always use an UPS.

I sure wish there were more details available, and more configuration options.  The manual says I should be able to configure gateway settings from a browser on a real computer.  All I can see is a status screen.  It does not have anyplace to log in, so I am stuck squinting at the lame phone app.  These tired old eyes need a full size monitor, keyboard, and mouse.  I hate phones.  That’s a children's toy.
