How to get school computers on the Internet 100

There are many methods: 1. Set the IP address of a network card on the machine that can access the external network, and connect the other machines to this machine through the switch, these computers should also set the IP, and set the gateway IP and domain name resolution IP to the IP address of the newly installed network card. 2 By installing ** software.

Such as wingate, sygate and other ** software, so that you can also access the Internet. 3. Install a router to access the Internet through the router. Routers are also cheaper now.

It is more convenient for routers to share Internet access. It's not like surfing the Internet, where the server is turned off and you can't get on it.

The Wide Area Network (WAN), which is commonly referred to as the Internet, is a network that spreads all over the world.

Local Area Network (LAN), as opposed to Wide Area Network (WAN), mainly refers to the computer interconnection network in a small area. This "small area" can be a family, a school, a company, or a **department.

The public network and extranet often mentioned in BT, that is, the wide area network (WAN); BT often refers to private networks and intranets, i.e., local area networks (LANs).

Each computer (or other network equipment) on the WAN has one or more WAN IP addresses (or public and extranet IP addresses), and the WAN IP address can only be applied for after paying the fee at the ISP, and the WAN IP address cannot be duplicated; Each computer (or other network device) on a local area network (LAN) has one or more LAN IP addresses (or private and intranet IP addresses), and the LAN IP addresses are assigned within the LAN, and the IP addresses of different LANs can be duplicated and will not affect each other.

The exchange of data between computers on a wide area network (WAN, public network, and extranet) and a local area network (LAN, private network, and intranet) is carried out through NAT (Network Address Translation) of a router or gateway. Generally speaking, the router or gateway will not block the external connection request initiated by the computer in the LAN (LAN, private network, intranet), but the router or gateway will intercept the request from the WAN to the computer connection in the LAN in most cases.

It's hard to say about this, but in general, schools use a network classroom to connect a host or switch to access the Internet. Strictly the IP will also be set for each machine according to the MAC address.

According to the phenomenon you described, it should be due to the fact that after you change the IP, the gateway to your classroom is not connected to the same network segment, resulting in the inability to connect to the LAN.

The solution is slim. It is to get the gateway permission, and assign your computer to a VLAN with the classroom that can access the Internet (generally computer classrooms use VLAN), and there is also a hand method, that is, generally if there is a switch cabinet in your classroom. If you can, connect your computer's network cable to the VLAN of the classroom (change interface).

There is also a network cable that connects to the external network directly plugged in.

As long as there is a machine that can access the Internet, you can use the ** server to access the Internet, it is recommended to use ccproxy to try.

A relatively simple way is to open the school's homepage directly, enter from the network center to try, and the general school's campus network will have a place to log in and log out users in the network center.

Other workarounds:

1. Browser problems:

Try to use Internet Explorer and turn off the pop-up blocking feature. Open the browser, click the toolbar "Tools" at the top of the browser, select "Internet Options", click "Connection" - LAN Settings in turn, if the content under "Server" is ticked, it means that the network is set**, and removing both checks means canceling the network**. To use WLAN normally, you need to remove the two checks at the "server" to ensure that the browser is not in use.

2. IP issues:

It is recommended to obtain the IP address automatically. To check the IP, click in order: Start - Control Panel - Network and Sharing Center - Wi-Fi Connection - Details - IPv4 Address, or click the Wi-Fi icon in the lower right corner, select CMCC, right-click, and select Status to view the IPv4 address.

3. Other issues:

Use the authentication screen (portal screen) in your favorites. If you save the authentication screen (portal screen) that has been popped up in the browser and open it from the favorites the next time you use it, the authentication screen (portal screen) will not be displayed properly.

In addition, the school generally has a department dedicated to overhauling the campus network, or related small programs and ***, where the situation can be reflected, and the relevant personnel will solve it. Maybe it happened that the campus network was being repaired and upgraded during that time, maybe it would be good to wait a while, and you can try again later.

withCampus NetworkSure, the school will keep the browsing records in the campus network for more than a month, if there is any problem, you can directly trace, even if you are not using the campus seepage network, there are also records in the operator, so don't think about doing anything illegal, as long as you want to check it, you can find it.

The campus network is a broadband multi-network that provides teaching, scientific research and comprehensive information services for teachers and students. First of all, the campus network should provide an advanced information-based teaching environment for school teaching and scientific research.

The campus network system is divided into the core layer, the aggregation layer and the access layer from the structural level. Functionally, it can be basically divided into campus network center and teaching subnet.

Office subnets, dormitory subnets, library subnets, etc. According to the number of campus network users and network applications, it can be divided into three types: large campus network, medium-sized campus network, and small campus network.

Based on the characteristics of the above-mentioned campus network, we must fully consider the characteristics of the network such as advancement, standardization and openness, reliability and availability, activity and compatibility, practicability and economy, security and confidentiality, scalability and network flexibility when designing the campus network, and make full use of the limited investment to build a comprehensive network with high cost performance.
