fast 5688W gateway is cutting in and out
Hey! I just got our new t-mobile service and have placed the gateway in a decent location (as high as possible) on top of our China cabinet. The signal is staying at "good" or three bars. Fo...

Shortly after getting established, the following Friday (last week) it dropped everything (including Wi-Fi) 4x inside an hour. Wi-Fi seems ok since then, but it has dropped Internet WITHOUT REPORTING SAME both 3 days ago and 4X AGAIN this afternoon. The biggest issue I gave with that (at the moment) is the complete and total failure of the gateway to recognize and report the issue. Connected Wi-Fi devices (e.g. Xbox One S and X) will not report a network loss, but also not show any active network activity (active downloads in progress will simply halt).
Not being a network engineer, but having significant networking knowledge and experience, it appears that the gateway is using a method other than successful network traffic to judge the state of the connection, which is completely inaccurate and a major design flaw. As a result, the gateway fails to recognize the lack of a properly working connection and fails to follow any kind of automatic retry procedure to re-establish a stable, working connection. A power cycle reboot of the gateway will re-establish connectivity after the usual excessively long delay, but within an hour it's back to "showing" connected but not actually being connected.
This is basic low-level networking 101, and the gateway is failing miserably. This needs to be investigated and resolved ASAP. These continuing issues are only going to tank T-Mobile's reputation.
