How to set up a wireless network when a wireless router is connected to a fiber optic modem

The setting method of connecting to the router and not connecting the router is completely different, there is a router, the computer no longer has a broadband dial-up setting, and the account must be set up in the router.

1. First of all, prepare the computer and a network cable, it is best to have the router manual, check and confirm the login IP of the router, the account number and password are very important, some TP link router login IP is, some are, it is also useful.

2. A network cable from the cat is connected to the WAN port of the router, and the router is in working condition when the router is powered on. Connect the prepared network cable to the computer at one end and the RAN port at the other end.

Then the computer's IP:,Mask:,Gateway:

Same as routers), and you're good to go. At this time, you can log in to the router, another way, if you are a laptop, you can access the Internet wirelessly through the router, you can also log in to the router directly; In the Internet Explorer address bar, type:

Open the router page, and the general account and password are: admin.

4. Enter the router settings interface, the menu is very intuitive, and it can be configured with quick navigation. If it is a unit network, there may be a static address, so you can fill in the corresponding address; If it is a telecom modem, you need to choose the pppoe mode, fill in the account and password of your telecom application, and the others can be defaulted; It is recommended to use automatic assignment of address for wireless network configuration, so that mobile phones and laptops can automatically obtain the address to surf the Internet, set a recognizable ID name, set the password for user authentication, and everything else is default, and others can be temporarily not set, and you are interested in slowly groping for it.

Connect the network cable from the modem to the WAN port of the router, and enter the account password.

The LAN port is connected to a computer.

The computer IP is obtained automatically. ok。

Nowadays, many telecom broadband will send a fiber broadband optical modem, which has a variety of functions, making it very convenient for broadband users. So how do we connect the wireless router to the telecom fiber broadband modem, and how to set it up? The method of setting up a fiber optic cat on a wireless router is actually very simple, let me tell you below!

01 Wiring method of the hardware part. Connect the WLAN port of the wireless router with any network port of the optical modem with a network cable, and connect the device according to the methods of [Router Modem - Router WAN Port] and [Router LAN Port - Computer], as shown in the figure.

02Set the IP address of the router.

Open the IE browser on the computer, enter the router management interface, and find the [LAN port setting] under [Network Lead], because the default address of the optical modem is, so you need to modify the IP address of the router to ", the subnet mask is, and then click [Save] to complete the setting.

03Next, find the [WAN Port Settings] under [Network Lead] on the page that opens, change the WAN port connection type to [PPPoE], then enter the Internet access and password of Telecom, select Auto Connection, and click [Save] to complete the setting.

04Find [DHCP Server] on the page that opens, then select [DHCP Service] to enable DHCP server, set the address range to, and click [Save] to complete the DHCP setting of the router.

05Finally, configure the connection to each device on the wireless router, and set all the network referencing IP address acquisition methods on the computer to [Auto Acquisition], and you're done! Next, you can use the TP-Link wireless router to access the Internet wirelessly, and you can also use the TP-Link router to connect multiple computers to access the Internet at the same time.

The LAN port of the cat pulls a network cable to the WAN port of the wireless router, the specific method:

1. Connect through the network cable or unlimited connection, and then we enter the address in the address bar, and the general initial address is;

2. Enter the username and password in the pop-up dialog box; The initial password and user name are generally admin, and the specific ones can be viewed on the router; Generally on the back of the router;

3. Enter the router and select the setup wizard; Click on the next Internet access method, we select PPPoE (ADSL Virtual Dialing).

4. Below we enter the broadband account password; If your home is a monthly subscription, you can enter it; If it's not a monthly subscription, you'll have to think about it; After entering the account password; In the future, after your computer is turned on, it will automatically dial up to access the Internet. This means that you don't have to manually connect to broadband every time. If you don't want to automatically dial up the Internet, you can leave it out here;

5. The first two of the following are set to the signal name of the wireless router, which can not be changed; The second is the wireless router key; It is advisable to change it;

6. The first two of the following are set to the signal name of the wireless router, which does not matter and can not be changed; The second is the wireless router key; It is advisable to change it;

Wireless router setup reference.

Fiber optic modems are generally integrated with the router and generally have wireless functions. You have to ask the staff who installed the optical fiber for you to set it up, and only they know the management account and password of the optical modem.

If you want to use the wifi function, the wireless cat needs to go to the telecom first to apply for activation, and then there will be staff to come to the door to install.

2. Click on the network settings on the left, select PPPoe in the WAN port settings, enter the username and password given by the operator (if you don't know, call broadband customer service), and enter the DNS address (you can check your local DNS address on the Internet);

Note: If the router prompts that the network cable is not plugged in at this time, you don't need to pay attention to it at all!

3. Turn on the DHCP server;

4. For the wireless router, turn on the wireless network, turn on the wireless network function, and set the wireless login password (security option wpa-psk wpa2-psk, enter the key);

Save the parameters and it's OK,At this time, restart the router after connecting the network cable to the WAN port of the router,Wired is already available,Then open the wireless network card in the right corner of the desktop and right-click to view the available wireless network,Now your router broadcasts the signal,Double-click to connect,Enter the key to get it。 Wired and wireless access is available.

Configure the IP on the computer to automatically obtain, and in the future, you can go to the Internet by opening the browser directly on the desktop, and finally connect the computer to the network (wired, can be) to check whether you can access the Internet normally.

If you can't access the Internet, you can only connect to the computer that can access the Internet normally after dialing up the connection on the router, log in to the router again, and clone the MAC address in the WAN port settings.
