After I finished using the router, the cat main line was directly connected to the computer, why can

Landlord! To configure the router! 1. The home line is connected to the WAN Internet port of the router, and the PC is connected to the LAN port.

2. After completing step 1, the physical connection is completed. Next, let's move on to the router configuration. 3. There is a gateway IP and web login password on the back of the router.

4. Enter the gateway IP address in the IE column. Enter the router web configuration mode. Click Setup Wizard, Next, go all the way to Select Network Mode, select PPPoE, and enter the password to access the Internet.

Then click Next until you're done and save. After completing the above 4 steps, you can go directly to the Internet without having to click broadband dial-up on the computer. Because the router has dial-up is even better.

He dials automatically. Completed!

Is the router installed? If the router is installed, you can try unplugging the network cable of the router and restarting the optical modem to see if it can access the Internet, and check whether the network segment of the LAN port of the router conflicts with the network segment of the optical modem.

For example, the optical modem is generally Then, the network segment of the router cannot be and must be modified to (the middle 2 can be any number between 0 and 200, generally with 1, 2, 3, 4, 5. The WAN port of the router is set to automatically obtain the IP address to surf the Internet.

Hello dear! We'll be happy to answer for you. Why can a network cable be plugged into a router to access the Internet, but directly plugged into a cat can not access the Internet?

Answer: For ADSL and some old optical cats (PPPOE dial-up Internet users): This type of cat only enables bridging, but does not enable routing.

1. When you are a cat directly, you can't access the Internet without entering the password for surfing the Internet. Second, when the router is connected, the Internet can be accessed, and the computer does not need to go online authentication, because the router has entered the Internet access password when setting, and turned on automatic dialing or on-demand dialing. For the latest modems (non-PPPoE dial-up users):

The routing function has been activated, and the installer sets and authenticates the parameters required for Internet access when installing the fiber modem, and the computer does not need to authenticate the Internet, so it can be connected to the fiber modem directly. This type of optical modem essentially requires Internet authentication, which is different from ordinary dial-up (PPPOE), which is set up by the installer, and the user can use it directly, as if there is no password.

Summary. If it is plugged into an optical modem, it must use broadband dial-up because it is not an optical network. Enter the broadband and password, dial-up to the Internet, and connect to the network. And if you connect through a router, you can access the Internet without dialing up.

Please wait patiently for a few minutes, we are sorting it out, and we will answer you immediately, and please do not end the consultation.

If it is plugged into an optical modem, it must use broadband dial-up because it is not an optical network. Enter the broadband and password, dial the number to access the Internet, and you can connect to the network. And if you connect through the router, you can access the Internet without a keytalk and need to dial the first number.
