Broadband has changed its name, can optical modems and routers be used a second time?

Of course, this is okay, as long as it is not changed, then there is no problem, and it doesn't matter if you change the name.

It needs to be set up again.

1 Open a browser on your computer and enter your router's settings** in the input box, which will usually be marked on the main body of the router.

2 In the jump page, read the relevant agreement and click Agree to continue.

3. Fill in the broadband and password, as shown in the figure below.

4 Provide a name and password for the wireless and click Next below.

5 Set an administrative password, you can choose the same password as the wireless password.

6 After that, you're ready to set up and use the wireless network feature.

The optical fiber modem converts the optical ethernet signal of the optical fiber into an electronic message that can be recognized by the computer. Ordinary cats convert the analog signals in the ** line into electronic signals.

Many people will ask, can you use the ordinary cat used before as a fiber optic cat, here you can clearly tell that no.

Because ordinary cats belong to the first line access, and the optical core Sun fiber cat is a professional optical fiber access, the interface protocols of the two are different, and ordinary cats cannot receive optical signals, so the two cannot be used together. Shoot acres.

It needs to be set up again.

There are two scenarios to consider:

After changing the optical fiber, ordinary cats use the services of different broadband providers, such as replacing China Mobile with China Telecom, in this case, it is necessary to change the username and password in the router.

After the ordinary cat changes the optical fiber, it still uses the same broadband service provider and the user name is retained, in this case, you do not need to change the router settings.

After replacing the optical modem, the password provided by the broadband ** provider has changed, and the Internet access method may have also changed (dialing to dynamic IP), so the router must need to be reset again.

No, my family has just changed, it seems that the password has not been changed, just connect the line, you don't need to set anything, use it the same as before.

If the account password has not changed, there is no need to set it.

If you still use the original words, you generally don't use it, and the password remains the same.

1WAN port of the cat --- router; Router 1LAN port --- router 2WAN port; Router 2LAN port --- computer;

The port of the cat Internet cable is connected to the WAN port of the router, and the LAN port on the router is connected to the computer, generally the router has 5 ports, one is the WAN port and the other 4 are all LAN ports, which can be divided into four computers to access the Internet, but the WAN port can only be connected to the line of the cat, and the LAN port can be connected to the network cable of any computer;

How to set up the router to link the WAN and LAN ports: prepare two network cables; A network cable is used to connect the WAN interface between the modem and the router. The other network cable is used to connect any LAN interface on the router to the computer.
