Why is my wifi so slow

Common causes of slowing Wi-Fi include signal interference, insufficient router performance, device own problems, and broadband package restrictions. 1. Signal interference may come from many neighbors, thick walls or home appliances. It is recommended to adjust the router location and change the channel; 2. The old router has poor performance, so it is necessary to check whether it supports dual-band/tri-band and Wi-Fi5/Wi-Fi6 protocols; 3. Too many devices away from the router or background programs will also affect the speed. Different devices should be tested and caches should be cleaned; 4. The bandwidth limit of the broadband package determines the network speed ceiling, and you can query through the operator's app and consider upgrading the bandwidth.
