When we use Huawei routers, there may be a few minor problems. Of course, some of these problems may be caused by improper settings, improper use, or improper connection. 

If our wireless network becomes very slow, then it may be the reason that we use the routers too long, which leads to uneven internal cooling. At this time, it is best to open the window to ventilate the room, then close the router and wait until it cools before reopening the router. ,  also you can restore the use of the network.
