That cat light doesn't work. what's up

If Unicom broadband is used, the failure of the cat signal lamp indicates the failure of the cat equipment or the line, and there may be the following reasons for not having a network:

1, broadband is overdue or expired, and it needs to be paid or renewed in time.

2. The network cable is loose, so both ends of the network cable should be plugged tightly.

3. If the equipment is used for a long time, you can turn off the light cat and computer 10-20 seconds, and then turn on the power to restart.

4. If the above methods cannot be restored, it is recommended to contact the local customer service hotline staff.
