Dehua county super network card is dead.

Dehua county super network card died for the following reasons:

1. There is something wrong with the network itself. The bandwidth of the server where the connected target website is located is insufficient or the load is too high.

2. The network cable problem causes the network speed to slow down. In one case, the internet speed was very slow when it was first used. In another case, the network speed was normal at first, but after a while, the network speed slowed down.

3. A certain port in the network becomes a bottleneck, which causes the network speed to slow down. The router's WAN port, LAN port, switch port, hub port and server network card may all become network bottlenecks.
