This is because of the signal attenuation caused by interference on the Wi-Fi signal. The number of antennas, signal interference, transmission distance, and obstacles can all affect the Wi-Fi connection rate.

• Other Wi-Fi signals in the surrounding environment may also interfere with the Wi-Fi signals of your router. The more Wi-Fi signals nearby, the severer the interference. You can use the Wi-Fi quality feature of the HUAWI AI Life App. On the router management screen, touch the icon on the right of the Internet to access the Wi-Fi quality screen, and touch REMOVE INTERFERENCE. You can also touch Show more on the router management screen, select Wi-Fi management >Wi-Fi quality, and touch REMOVE INTERFERENCE. During channel optimization, devices such as mobile phones and tablets will disconnect from the network. After the optimization is complete, devices will reconnect to the Wi-Fi network. Alternatively, you can restart the router to optimize the channel.
• The longer the distance between the device and the router is, or the more obstacles between them exist, the lower the Wi-Fi connection rate is. Place the router on a table or TV cabinet. Do not place the router in a weak-current box or corner. Move your device such as the mobile phone closer to the router.
• The Wi-Fi connection rate is related to the number of antennas in the device that accesses the router's Wi-Fi network. The more antennas, the higher the speed. Usually, a mobile phone has only one antenna, resulting in slow Wi-Fi connection rate. It is recommended that you test the Wi-Fi connection rate on a computer.
