When the computer is hot, the network is frequently disconnected, and when the network is disconnected, the cat's link light does not light up or flash. It will be fine as soon as the temperature drops. What is it, a computer or a cat? Disconnection is usually caused by cats. If the computer is overheated, the most likely result is that the computer crashes or restarts, not just the network card crashes.

When you say disconnected, if the network card is hot, it won't restart automatically, but the cat may restart automatically. You said that when the cat link light goes out, it is the time when the cat restarts, and when it flashes, it is the time when the cat starts to be normal.

You can check: use a fan to cool the cat and see if it will be disconnected.

Of course, it is also possible that there are both reasons.
