Wifi signal is full but pages load slowly

Slow web page loading does not necessarily mean a network speed problem. It may be caused by router interference, excessive devices grabbing bandwidth, abnormal DNS resolution or insufficient device performance. First, check the location of the router, stay away from interference sources such as metal and microwave ovens, use the 5GHz frequency band and replace the idle channel; second, check the number of connected devices, turn off automatic background updates, and enable QoS to ensure the current device first; then try to replace the public DNS, clean the browser cache or change the browser test; finally, check whether the Guangmao and the router are aging, and replace the new device or restart the router if necessary.
