The first type: external problems, caused by poor line contact, can only be reported as faults.
The second type: caused by high temperature.
The temperature of the cat or route is too high,
Exceeding its temperature tolerance limit,
Will automatically cut off when not in use,
Turn them off,
Then put them in a ventilated place,
Do it.
The third type: caused by data conflict.
One: the cat restarts,
Two: Routing reset, if any.
Three: broadband connection, download again, download again.
Four: Does the agreement get IP for free?
Conclusion: For the failure caused by data conflict, try again.
Everything is settled.
If it can't be solved, if there is an external network signal, use the 360 manual service recovery system to solve it.
