If the device is not connecting to the Wi-Fi, the connection might be slow. Place your device closer to the router for better speed. If there is no wifi connection at all, uninstall the driver and restart your device. Install the driver again and try reconnecting to the Wi-Fi. For more information, please refer to the [[Acer Iconia Tab 8 A1-840 Troubleshooting#Section_WiFi_Connectivity_Issues|troubleshooting]] page.
