How to set up a LAN in the dormitory, how to set up a LAN in the dormitory win8 system

It depends on whether your router is normal or an integrated one;

If it is an integrated one, you will generally see WAN ports and LAN ports, and some integrated routers have 4-8 LANs, which is actually an integrated switch. First, set the IP address and mask of the WAN port of the router to the IP address and mask that you use to access the Internet normally, and then add a default route to the gateway you use to access the Internet normally. The LAN port is configured with a private IP address, for example, a mask; If the router supports the DHCP function, it is recommended to enable it, and note that the DNS server address inside must be set correctly; Then turn on the NAT function of the router (generally integrated routers are turned on by default); The computer in your dormitory is directly connected to the LAN port, and the IP address can be obtained automatically.

If you are a common router, you need to configure two interfaces, one of which is configured according to the WAN port and the other is configured according to the LAN port, and then enable the NAT function and set the default route. Please refer to the manual of your router for the NAT function. This type of router generally does not provide DHCP function. In addition, you also need to purchase a switch for interconnection.

DNS: the domain name resolution server, which is to complete the conversion between IP addresses and domain names; For example, convert this domain name into the corresponding IP address, and then use the IP address to access baidu

If you don't know the DNS server address, under the premise that your computer can access the Internet, enter cmd in winxp-start-run-enter cmd, and then enter ipconfig all You can see the corresponding IP of the DNS server, there may be 1-2 addresses, one of which is for backup; Fill them all out in the corresponding DNS server settings of the router's DHCP.

Set the IP address of each computer

Common gateway.

Add another switch and connect it directly.

The premise is that your school's campus network is not certified, and it is only possible to allow **.

This looks like your school's network configuration. If you don't have an authentication server, once you install the switch, you can connect to the computer. If you have an authentication server, you need to buy a router.

Buy a wireless router.

Each machine uses a wireless network card.

The router has a manual, just read the manual, and if the router port is not enough, buy a switch to build.

Win8 steps to set up a LAN:

Note: (Requires a working computer (with win8 system installed) equipped with a wireless network card (support wifi hotspot)).

1. Press and hold Windows+X on the computer desktop and click Command Prompt (Administrator) to enter;

2. Then enter the netsh wlan set hostednetwork mode=allow ssid= (here enter the name you want to give your local area network) key=(here enter the password you set), and then press enter to enter;

3. Then continue to enter netsh wlan start hostednetwork, and then press enter;

4. Set the "wifi" at the bottom right of the computer to exit successfully

It's very simple, you can use the wifi assistant under the Rubik's Cube software, or you can use 360 to connect me wifi. If you want to do it yourself, you can use DOS to set it, but it's just a little troublesome.

As long as you all have a wireless network, you have already established a local area network...

Win8 doesn't have this function.,You can place a Rubik's cube and build a wireless hotspot.。
