How to connect campus network with router or network cable?

The operation steps of connecting campus network with router or network cable are as follows:

I. Router connection:

If there are multiple routers in the campus network, there are two kinds of routers: the main router and the auxiliary router. Connected to the external network is called the main router (the incoming line of the external network is connected to its WAN port), and connected through the main router or the secondary router is called the secondary router. The main router and the auxiliary router (or two auxiliary routers) can be connected to the LAN ports of both parties through a network cable for series connection.

Second, the router settings:

1. Enter the IP address of the router: run the browser on the computer and enter the IP address of the router in the address bar (refer to the instruction manual of the router or the instructions on the nameplate on the back of the router), such as 192. 168. 1, and press enter. In order to facilitate management, especially in the case that multiple routers may have the same login IP, the secondary router can modify the IP address of its LAN port to:192.168.1.2 and so on.

2. Login to the router: After entering the router login interface, enter the login account number and password (refer to the instructions on the router manual or the nameplate on the back of the router), generally: admin or boot.

3. Setting up the router: Common settings mainly include the following items.

A. Enter the account and password for automatic dialing. After entering the setting interface of the first-level router (no second-level router is needed), click "Network Parameters" on the left, select PPPoE dialing mode, and then enter the account number and password provided by the network service provider and save it. This way, you can dial up the Internet automatically through the router.

B. set up DHCP.

Main router: select the DHCP server tab, click "Enable DHCP" and set the IP address (the starting address and ending address of the address pool can be set according to the default value, The maximum limit is generally192.168.1.2 ~192.5438+068.5438+0.20438.200000066106 DNS server address. In this way, the computer connected to the router can automatically obtain parameters such as IP address, without manually setting parameters such as IP address.

Secondary router: Select the DHCP server tab, click "Do not enable" DHCP and save it.

C, set the wireless password. In order to prevent other users from surfing the Internet illegally, a wireless password needs to be set. Click "Wireless Settings"-"Wireless Security Settings", select an appropriate encryption method, and set a password of more than 8 digits. Finally save. Multiple routers need to set wireless passwords, which can be the same or different.

D, modify the router login password. Because the router has a default universal account and password, generally: admin or boot. Any computer connected to the router can log in to the router or even tamper with the router parameters, so you can enter: Security Settings-Modify the login password to change the default password to a custom password.

(4) Restart the router: after the setting is completed, the router needs to be restarted to take effect. For the restart method, just select "Restart Router" under system tools.
