Thermal Issues With Home Internet Gateway/Router as a Cause of Dropped/Slow Internet or Wi-Fi Connection

Just an observation I have made regarding the drops. I can see service here tends to be delivered from two different towers. The tower at 5.3 miles 360 degrees, North, is where the secondary channel is delivered. The 4G LTE "primary" signal appears to be delivered from a tower 270 degrees, NW roughly 2.5 miles away. When the 5G secondary channel drops this becomes clear as traffic appears to be interrupted and of course the routing tends to be slow to recover and of course more latency and slower traffic. It is rather difficult to locate a router where the primary and secondary signals originate from two different locations and have reliable results. It appears to me most of the signal disconnects I have seen have been related to the loss of the secondary 5G channel and I am pretty sure this is mostly due to T-Mobile doing work on the tower equipment. It does make it difficult to know when T-Mobile is not transparent about service work and service delivery. The system may be designed to do traffic hand off but the process does not appear to be seamless.
