Wifi link timeout under macbook apple system

Suggest the following troubleshooting methods:

(1) There are software errors in the operation of Macbook, Cat and WiFi routers. It is recommended that Macbook, Cat and WiFi routers be turned off and restarted.

(2) Check whether the heat dissipation and ventilation of the WiFi router are normal, so as to avoid the unstable operation of the WiFi router caused by high temperature, and thus the mobile phone cannot be connected;

(3) Reduce the distance and physical obstacles between macbook and WiFi router, and ensure good coverage quality of WiFi signals;

(4) Check whether there are too many people connecting (rubbing) WiFi, watching online videos, playing online games or downloading files, so that the hardware load of the WiFi router is too heavy to respond to your networking request;

(5) Check whether there are strong radio interference sources around the macbook and WiFi router, which will affect the transmission quality of WiFi signals between the macbook and WiFi router;

(6) Check whether the WiFi router configuration restricts the mobile phone network connection.

(7) Take other mobile phones to test whether the WiFi router can be connected. If you can't connect, there may be a software or hardware failure in the WiFi router. You can reset the WiFi router to the factory status first, and then remove it. If the fault still cannot be solved, it is recommended to replace the WiFi router.
