5G Gateway intermittent outage

I'm having the same or very similar issues. 

My old 5G Gateway began disconnecting frequently a couple of weeks ago. During my research, I decided to just upgrade my home service to an All-In plan and add cell phones. Received the new gear earlier this week, set it all up, and it is behaving the same way. 

The Gateway will remain stable if I do nothing, but it seems as if most interactions from me - initiating a browser search or running an internet speed test - will cause the service to drop for a few minutes. Sometimes it recovers within a couple of minutes on its own, but sometimes it causes the Gateway to powercycle and that can take 4 to 5 minutes. Sometimes the Gateway reports an unrecognized or invalid Sim Card in the Gateway. Sometimes my phone or computer says that I'm connected without Internet. Now and then it says something about a problem with DNS. I occasionally have to power the Gateway off for a couple of minutes to get it to connect again, but if I try to do anything on the computer, it's off again before you can get anything accomplished.

The service is unusable like this. I even reconnected my old Gateway and did some troubleshooting with it, but both devices are behaving the same way. And T-Mobile hardly offers any way to report a problem online without making a phone call to a tech who always has to go over the basics every single time. It's infuriating.

Has anyone recovered from this problem yet? What's the solution, besides calling and pestering people until something magical happens? 

Thanks, 

More Annoyed Than Usual.

I just purchased a brand-new white Gateway last week and it worked perfectly with a much stronger Wi-Fi signal and higher speed than my previous fiber based AT&T-internet. But then I found that it rebooted every time I switched my PC Wi-Fi connection from my iPhone Hotspot to the T-Mobile Gateway. It rebooted during the Wi-Fi reconnection to all my PCs but no problems with iPhones nor Smart-TVs. It also happens similarly when I switch Wi-Fi connection from AT&T to T-Mobile, but no problems when switch reversely.

I talked to the T-Mobile tech-support, they believed it was hardware issue and sent me a replacement. I received the new Gateway and tested yesterday. An identical problem happened again. So, I believe this might be caused by the software not hardware. I am still waiting for a solution since I must use PCs with Wi-Fi Hotspot at work and switch to T-Mobile Gateway back home every day.

I spoke with tech support about blips in WiFi downtown near many towers and he told me several complaints were made about service that day.  He also stated that he unplugs his tower on a Sunday night so when he works Mondays it is re easy for the week. 

Traffic filtering/shaping/restrictions cause this.  I had this issue and replaced +5 gateways.  Each firmware update would break it again. 

Call BBB if you want resolution.

I'm just a customer but have you checked the Advanced Cellular Metrics to see if they look good?

I'm about the same distance from their tower also and have had no disconnects other than ones I created. I have only had it for a month.

Since you replaced the gateway and experience the same problem perhaps the tower is where the problem lies.  

Having the same problem and I've spoke with customer service 5 times and get the same troubleshooting crap every time. I'm to the point that I need to find another service provider. Every Rep I've spoken with has been so nice and seemed genuine, but haven't helped with the problem at all. I often work from home and I depend on them to provide the service that I am paying for.
