I started to get weird issue with my mobo - when i turn on the computer (in the morning, turned it off previous evening/night), i get no internet. I have wifi turned-off by default and are connected to router via cable. And it randomly does not work and running the diagnostic does not seem to fix it (it recommends turning on wifi, which i did and that worked, but its half the speed of cable, so its no solution). Rebooting the computer fixes the problem. Any idea whats going on? Could it be cable issue? Cause the plastic thing on the end of the cable, that keeps the cable in the port, is broken off, so when i plug it in, its bit wiggly. But it flashes green, so it seems to be working, and anyway, "reseating" it does not fix the issue, rebooting computer does. So it seems more like a software problem?
Happened only twice so far, but the computer was fine for half a year.
EDIT: Only thing that changed recently (aside of any potential Windows updates, that i might have missed, but i am not aware), about 2 weeks ago, is that i changed router, as i changed internet provider (in order to move on from metallic 50Mbit to optical 1Gbit, and they gave me their own device).
