This is an issue where your internet connect switches on and goes limited-access after few hours. It seems to be only peculiar to your system while others on the same network are not experiencing the same problem.
During that time the WiFi indicator icon shows there is connection established with your router and it is functioning proper for use, to browse and carry out other activities on the net. Not too long a small yellowish warning sign is displayed on top the WiFi icon indicating there is no internet access or limited access on the system tray. When you decide to disconnect and reconnect it the WiFi establishes a connection that allows you to use your internet connection again. Not up to two hours into the use the same limited-access error reappears thereby creating a repetitive process.
