What are the settings required to set up a long width LAN?? 10

The gateway is OK by default, and the DNS must be local.

High-performance Internet café routers.

A 24-port switch connects to your 20 computers. About 400 yuan. For example: tp-link

tl-sf1024d 。

The network cable is 300 meters in a box, and you buy it according to the actual situation. A box of orders is 550 yuan.

The crystal head is in a box, usually 100 pieces. Of course, there are 50 of them. An average of $1.

The router has the function of automatically assigning IP addresses, which you can leave unassigned. Of course, it can also be assigned manually].

Your LAN is primarily used for something.

You are there to use.

At home still.

in the office.

VPN is a common way, you can use the "TeamViewer" software to form a VPN LAN with any two computers, so that the external network and the internal network computer are like forming a temporary LAN, which greatly facilitates the mutual access between the internal and external network computers.

In the first step, both the company computer and the extranet computer need to install TeamViewer, and the program will automatically assign an ID and password to the current computer after launching, and now remember their respective IDs and passwords respectively.

Step 2: Enter the ID of the company computer in the "Partner ID" field of the TeamView window on the Internet computer, select the "VPN" service, but click "Connect to Partner". At this time, the program will automatically prompt you to install a virtual network card, and after installing the virtual network card according to the prompts, a VPN dial-up connection will be generated on the respective computers.

Step 3: After the VPN dial-up connection is established, click "Connect to Partner" in the TeamViewer window, and both computers will automatically activate the VPN connection.

Step 4: Return to the program window, prompt to enter the password corresponding to the company computer ID, and after the successful completion of the connection, the program will automatically pop up the connection status window, where you can see the IP of the partner computer, that is, the internal network address of the company computer in this VPN LAN, similar to ", remember this IP address.

Fifth, you can now access the company's computer resources in the extranet computer, and set the company's computer save resource directory to share. Then enter the above address in the Internet computer explorer, enter the company computer account and login password according to the prompts, and then you can open the company computer for access after connection, and the specific operation is the same as accessing the internal computer in the company.

When it comes to home networking, it's nothing more than a combination of a few computers, a few network cables, and a switch! However, there's a lot to learn! For example, how to make all the computers in the home can access the Internet at the same time?

How to choose a cost-effective connected device? How do computers connect to each other? That's what this article is going to discuss!

1. Preparation of networking equipment.

Here the author assumes that you have applied for ADSL broadband service from China Telecom and have installed it in place. When building a shared LAN, please check your ADSL modem product description first, if it supports the routing function, then you can save the money of buying a broadband router; Otherwise, this equipment is essential;

In addition, another indispensable device is the switch, which relies on the mutual communication between computers as a relay device; There is also the need to install a network card for each computer to be responsible for receiving data, as well as urgent obituary fathers.

Small LANs only need to have switches, computers and cables, and large ones need routers, switches, hubs, and cables.

First of all, the server, then you have to prepare routers, switches, network cables, etc., and of course you have to apply for a broadband to go online. The specifics depend on your configuration.

8 or 4 hubs, ranging from 30 to more than 100 yuan, it is recommended to buy a good one, otherwise it will be very annoying to go offline.

8 computers (with network card).

Network cable x root, on the meter of a dollar or so, the crystal head is at most a piece of money can be sold hub network cable to give you a few.

ADSL Internet subscription monthly or yearly, the operator will provide a route + modem in addition to the operator part, 200 yuan should be able to get it.

Routers, switches, network cables, computers.

Incoming line - >

Firewalls, routers--- switches – > computers.

One ADSL (provided by Telecom).

Router: A DLINK 405 150

Switch a TPLink 80

The network cable is a few yuan per meter.

Crystal head 20 amp yuan apiece.

1。Use a hardware router to buy a small router and then connect 8 machines to the router and surf the Internet through the router (9 network cables, 18 crystal heads, 8 network cards are required) (advantage: there is no host, so any can be turned off at any time).

2。Use a switch or hub to use a machine as a host (shared dial-up connection) to access the Internet.

Requires 9 network cables, 18 crystal heads, and 8 network cards) (advantages: the ** of the small switch is cheaper than the router, but the host has to be turned on all the time).

If you have 8 machines, I recommend that you use a router, and the performance of the computer as a host may not be as good as that of a router.

The installation and setup of the router is as follows:

1.First connect the line, you can refer to the figure below.

3.Once you've logged in to your backend, select Quick Settings and click Next4Choose the way to access the Internet, usually ADSL users choose the first PPPoE, if you use other network service providers, then choose the following two according to the actual situation, if you don't know how to choose, directly select the first item to automatically select, convenient for novice operations, click next after selection;

5.Enter the account and password applied for from the network service provider, and go directly to the next step after entering.

6.Set the wifi password, try to make the alphanumeric combination more complicated, and it is not easy to be rubbed off the network.

7.After entering it correctly, it will prompt whether to restart the router, select Yes to confirm the restart of the router, and you can access the Internet normally after restarting the router.

[Home Network Environment Wiring]:

1. There is a cat (modem): cat (modem) - router WAN port; The LAN port of the router --- a computer.

2. No modem: network cable --- router WAN port; The LAN port of the router --- a computer.

Computer enters the router]:

1. The computer IP and DNS settings are automatically obtained.

2. Open the browser - enter the general router address is this or check the login information on the back of the router) into the route - enter the user name, password, (the default is generally admin).

Set Router Dialing]:

1. In the [Setup Wizard], select [PPPoe Dialing] (some are ADSL Dialing), enter the Internet user name and password according to the prompts, and save.

2. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPPoe Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

To be able to log in to the route, oh, hehe, IE address bar input route, the back of the route generally has a login address and user and password), note that your computer IP address should also be set to be in the same network segment, generally the last number is different.

As follows: After entering, first choose the Internet access mode (PPPoe, static, dynamic IP), and choose the first item for broadband, and the account password must be filled in. If it is a local area network, you need to ask the network administrator.

You can try dynamic IPs first. Remember wireless parameters: authentication, encryption method, password, etc.

Save the settings and restart the route.

It's over. Oh, and the computer is generally not set up. To set, the network card (the same as wireless wired) is set to a fixed IP, which is different from the last digit of the route, and the gateway is the routing address. It is better to fill in the DNS. (It's different from place to place, ask Netcom or Telecom).

Wireless needs to select the parameters you remember above and set them accordingly.

Routers generally have manuals, which can be referred to.

The addresses of our most commonly used routers are or.

Once inside, find the DHCP setting and turn it on.

Then set the IP of each computer to be automatically obtained.

Use a computer to set up the IP, you there, and then enter your gateway in IE, log in with the username and password of the route, generally admin admin after entering the setup wizard, select PPPOE Enter your adsl number, and password, and you're done.

In many cases, it is necessary to set up a small and medium-sized local area network, how to make more cost-effective use of existing resources for networking? In fact, the use of Windows2000 operating system + network card + switch, you can provide a network solution with good performance and absolute economy for the majority of small and medium-sized users. The networking adopts the mode of host and client.

The host requires the installation of the Windows 2000 operating system, and the two network cards are plugged in for the uplink (ADSL) and downlink (switch or hub) two network skins, and the physical connection between the switch and the network cards on each client is established. Of course, this does not realize the real meaning of network connectivity, and needs to be set up on the host and client to realize small and medium-sized network connection, resource sharing, Internet access, and corresponding network management. First, set up the protocol for host installation.

Open the Windows 2000 "Control Panel", enter the "Network" item and select "Local Connection", the "Properties" of the base point will pop up a dialog box, and then click "Install" will prompt you to install "Customer", "Service", and "Agreement". Installing the "protocol" is a key step to realize the networking, "adding" the rasppoe protocol, and "installing from disk" can find the directory where the file is located to install this protocol into Windows 2000. Here's some follow-up:

System Update Settings - Prompts that the installation is complete. Click "Start - Run - raspppoe". Complete the following settings and confirmations:

1.Specify the network card to which you want to connect the ADSL modem; 2.Press "Query Online Service Device" to check whether the Online Service Device exists; 3.

Click on the Seednet or Hinet ADSL preset connection device; 4.Press item 4 to create a new "Dial-up Online" shortcut on the desktop, and create a new dial-up profile in the "Dial-up Network"; 5.Press the "End" button.

The slave setup is relatively simple, mainly for the network connection attributes. After these tasks are completed, a small and medium-sized LAN is formed, and it is very economical and practical to share broadband Internet access with a host and 50 to 100 clients. The Windows 2000 system is easy to operate, the operation is more stable, and the good software environment with the excellent quality of the top star switch tailored for small and medium-sized LAN will make the performance of the entire LAN exceptionally good.
