Can I still use LOID before Telecom Light Cat is restored to factory settings?

After the light cat returned to the factory settings, the previous LOID was gone. You need to register again.

Open a browser and type192.168.1.1? Enter the equipment registration interface. If you use a router, please avoid the router, and open the device registration interface after the computer is directly connected to the telecom optical cat.

According to the SMS prompt sent by telecom, enter the logical ID number in the "Logical ID" box. There is no need to fill in the password, just click the "OK" button. Prompt for registration, as shown in the figure below:

Generally registered to 17%, the network G light is always on. At this point, you can access the Internet normally by clicking the dial-up connection or reconnecting the router.
