Without knowing more about your networking setup maybe try a different WiFi channel on your router. You can ping your gateway device to verify if this is an internet issue or a wireless issue. If the pings do the same thing to the gateway it is a wireless problem. To find your gateway IP run ipconfig /all to see the device IP address. You can open 2 cmd windows and ping 8.8.8.8 in one and then ping the gateway in the other.
