You know what to do; if you call your ISP technical support, they will ask you to restart your network hardware. This is for good reason, as restarting your PC will clear out running applications and caches that may be conflicting with your connection.
Restarting (rebounding) your router (usually a combo unit containing a router and modem) will clear its cache and re-establish a reliable online connection. If you have a separate modem, restart that as well.
Restart the router by unplugging the power button for 30 seconds and then plug it back in. After powering up the router, restart your PC and see if you regain a stable Wi-Fi connection.
