5G Home internet keeps dropping!

If it is a company machine they may have to do so as many do lock down the clients so the users don't have administrative access. At HPE we did have administrative privileges and for our job it was imperative as we were doing network troubleshooting and remediation for customers. To run WireShark in its full capacity you really need to have administrative access. It may just be that T-Mobile has the traffic controls set where throttling of the traffic is a bit aggressive and that leads to the problem. 

If you can get the cellular metrics reported from the gateway it might help. Knowing if you have a strong signal is not enough. Knowing the RSRQ, signal receive quality, and the SINR, signal to noise ratio are actually important to know. If the signal is clean, i.e. good quality with low signal to noise ratio, the performance is usually better as there is less packet loss and/or damage. The session flow is smoother as there are fewer retransmits and better utilization of the bandwidth available. A stronger signal is a good thing but if it is dirty well it will not perform well. If you have the Sagemcon or the Arcadyan gateway the only way to get the metrics reporting is with the T-Mobile home internet mobile application on your phone. The bars on the LED screen are very generic and do not tell you much as you probably can tell. If you get 3-5 bars that would be best. Lower well, it is not much to write home about. Knowing the cellular signal band is helpful for understanding and expectations as well. We are rural in east TN and when they bumped us from the n71 to the n41 I had some concerns at first as I have seen numerous users writing about how the n41 was great for a month or so and then went horrible. So far it has been working extremely well. I think they do a better job with the n41 deployments in the rural areas than in a densely populated urban area. In some markets they need more cells than they probably deploy and tend to overload the cells and try to get by with more bandwidth controls. Just my thoughts.
