Why does my internet stop working only on laptop?

[Flying Spaghetti Monster]

The source of the internet is through an ethernet cable connected to my laptop. Sometimes the internet will stop responding on the laptop but the wifi my laptop gives off by using connectify to my phone still works fine on the phone. I checked different browsers, there's no difference. Only restarting helps.

It's a windows 8 toshiba.
Josh, I don't think that's the problem because then my laptops wifi signal would also not work.

This happens when connectify is on, and my phone connects to it automatically.
Well the thing is Connectify was always on when my laptop was on. But, I uninstalled it and it still happens at least once a day.
They're up to date but I don't think it matters because the signal is through an ethernet cable.
