Wireless routers are hot for the following reasons:
1. It's hot. In the hot summer, if the indoor temperature is not controlled, or there is no air conditioning, electrical products will generate a lot of heat.
2. The router also has too little heat dissipation. The number of heat dissipation holes of different routers is different, and if the heat dissipation holes are too small, the router will be very hot when it is working. Solution: 1, control the room temperature. On hot days, move your router to a cool place and turn on the air conditioner. 2. Replace the router. If the router is hot because the heat dissipation hole of the router is less, you have to change the router that has more heat dissipation.
