Everyone's log displays errors like that and although at first glance you would think the world is coming to an end, upon closer inspection you see that all the errors are happening within the space of a minute or two and then normal service resumes.
The T errors don't register willy nilly. Each category reflects a specific type of error which you obviously aren't suffering. If you are having problems with frequent disconnects I would suggest you post your power levels and setup a
BQM graph if you haven't done so already. It is all great diagnostic evidence for the tech if you need to call one out.
