The possible reasons for the instability of the wireless router and WiFi disconnection are as follows:
1. Poor heat dissipation causes the chip to overheat, affecting the working performance.
2. There is electromagnetic interference.
3. The network cable of the router is loose.
4. The router ages. The solution is as follows: 1. Place the router in a ventilated and open place. Users who often hang up and download can install a radiator conditionally. 2.. Try not to use wireless mouse and keyboard, especially near wireless devices such as set-top boxes. Stay away from microwave ovens, cordless phones. Conditionally, you can replace the 5Ghz router to avoid the congested 2.4Ghz band. 3. Check whether the connection between the WAN port and LAN port on the router is loose, and reconnect the router to ensure reliable connection. 4. Replace the router.
