I've seen software claim it can tell what it is but after decades of working network issue I can report that I've yet to have software tell me "it's this or that." I do use tools like an Android phone with a WiFi Analyzer to check out the location and another laptop to see if it's OK on my good laptop and phone.
Given such sparse details I have to write it's going to be a rough haul.
My internet service keeps dropping. I have Windows 7 pro and Xfinity. Is there software to log errors that are causing this so I know if it's my PC or myprovider?
