This usually happens due to the fact that your laptop is located far from your Wi-Fi router. The majority of larger objects that are that block the path, like walls, as well as other things in your home or office, that utilize radio frequencies interfere with the Wi-Fi. If you are unable to move your laptop as close to the router, you may update the driver software and then reset the router's configuration to the factory default settings.
