How can I determine if I cannot access the Internet?

1. Ping 127.0.0.1 or ping localhost

Ping 127.0.0.1 and check whether the TCP/IP protocol stack is normal.

2. Ping 192.168.1.1 to check whether the connection to the vro is successful.

(In the test, if I unplug the network cable connected to the vro, the error 651 is returned)

3. Check if the network adapter is disabled. Choose computer> Management> Device Manager. (This time the connection fails. the user name and password are correct. The password is 651 incorrect. This may be the reason why the network adapter is disabled)

 

No.

You cannot connect to the TP-link directly. All tried
