Broadband random instability

[#1]

In recent months I've begun to notice an increasing frequency of occasional, short term, broadband 'dropouts' in my Plusnet broadband service.  I'm not sure whether these are DSL/FTTC service failures to the property, or something else going on with my modem & mesh wifi system, which until the last few months had been pretty reliable.

Dropouts seem a bit random & short lived, with respect to time of day, and usually by the time I have have made it to check the modem the DSL light is stable.  

Is there anyway Plusnet agents can look at the stability history for the connection to my property?

@mushroom_daddy What set up have you got at the moment? It would be useful to see some statistics before we made any suggestions.

Thanks for your interest.

The modem is a Openreach HG612 and that connects to a WiFi mesh system (Tenda MW6-3).  It's all OK when working, which is indeed most of the time, but for the annoying occassional dropouts.

OK - as I'm unfamiliar with either of those two items, does either of them provide any useful statistics - system up-time/error logs/connection data, w,h,y.?
