Broadband cat dialing error 651, a false alarm

A 651 error occurred when dialing a few days ago,

The network is no longer needed for a few days. There are three lights on the cat, but they are not flashing. After consulting the Customer Service of China Unicom, he said that the link light is on, indicating that there is no problem with the direct line of China Unicom, and the data light is not on, it should be that the cat is broken. Later, with the help of Baidu, I found the cause, which may be the reason why the network connection was disabled. When I opened the network connection, I found that the network connection was disabled. I used to use the wireless network a few days ago, to avoid confusion, disable the local connection.

Find the cause and enable the local connection. The cat's lights flashed again, which turned out to be a false alarm.
