Please check the network first, and the Boox e-readers officially support the 802.11b/g/n network and could not connect to networks over 2.4GHz.
Please try to connect another Wifi network, such as mobile hotspot on your mobile phone or the McDonald's Wi-Fi.
Please kindly check whether you have built MAC whitelist on your router or not and whether your firmware is the latest one or not. If not, please try to update to the latest firmware first.
Please try to reboot your device and your router first, and then please try to choose the network you have connected and press the “Forget” button, then please try to reenter the password to connect the network.
Please provide a picture or video about the message from the device if you still could not connect to Wifi successfully.
