The Redmi Pad SE 8.7 meets the certification and inspection requirements. The quality of the Wi-Fi signal is greatly affected by the connection distance and usage environment. Too many devices connected to the same network can strain the router and reduce signal quality and internet speed for each device. Besides, outdated firmware on the router or outdated drivers on the devices can affect performance. Long distance from the router or the presence of many obstacles between the router can affect the quality of the Wi-Fi signal and cause an unstable connection, which is a normal phenomenon. It is recommended that you use it close to the router.
