Well, for what its worth the power levels and SNR are all within spec at least at the time you took them.
Your network logs on the other hand dont look so clever.
Lots of T3 timeouts suggest some sort of upstream issue, or at the least at certain times of the day.
I take it you turned it off and on again recently, at that would reset the count.
The only things you can do as a customer is a factory reset via the pinhole at the back, and check the coax cable is in good and tight.
Short of that I'm afraid you are in virgins hands.
Unless anyone else here has a better idea?
