Advice 1: How to share LAN

Many companies, businesses and even homes have long practiced the use of local networks. It is very convenient and economical. But there are situations when you want to create a separate user group, United in a different local network. It is absolutely not necessary to completely change the architecture of the network.
How to share LAN
You will need
  • The switch or router.
Instruction
1
There are several ways to partition a local network into subnetworks. The simplest way to just change the IP address of the required computers and the subnet mask. Open settings of the network adapter. Locate the "TCP/IPv4" and go into its properties. You will see IP address, say, 100.100.100.8. and subnet mask 255.0.0.0.

Change the IP address to any other address, for example: 210.50.150.8. The subnet mask will automatically change to 255.255.255.0. Do this for the rest of the computers that you want to separate from the local network and combined into a new one. Note that when you enter a new IP address, the first three segments have to do the same on all computers.

If you want to completely eliminate the possibility of information exchange between computers of two different LAN networks, get a switch. Connect all of the computers that you plan to separate from the old network. Simultaneously, the above disconnect the device from the old switch or switch. As a result, you will get two independent local area network. The IP addresses of the computers you can leave the old, because it will not hurt network performance.

Advice 2: How to set up LAN games

Sometimes you get bored. And that would somehow kill time, you play computer games. But playing alone is boring, and you have the support of a local network and, of course, your friend.
How to set up LAN games
You will need
  • - at least 2 computers
  • - compressed network cable
  • - game one version
Instruction
1
Open the start menu. Hover the cursor over the control panel, open it. Locate the shortcut to "Network connections". Open it.
2
Before you come to all your connections. But you need a LAN connection. Hover over the shortcut and right-click on it. You will see a window (see picture), click on properties.

Window opens the LAN settings. Choose Internet Protocol(TCP/IP). Open it.
The LAN settings
4
Will appear in the properties window the Internet Protocol(TCP/IP). Put the settings from "Obtain an IP address automatically" to "Use the following IP address".

5
The cell IP address, enter the following numbers: 123.123.123.1. to enter without points, your PC'll share.
6
Next, enter the numbers in the subnet mask: 255.255.255.0. The point set is not necessary. In the remaining columns to put anything not necessary. Click OK.
7
Doing the very same thing on another computer. Only where it says IP address, enter another combination: 123.123.123.2. Without points. The subnet mask is the same. Connect the network cable. And you can play.
Note
Please note that the games you play, was one version. If they are different versions, you will not be able to play them.
Useful advice
Check out all of the numbers that you entered.

Advice 3: How to measure network speed

Measurement speed local network takes place both manually and programmatically. To check, use deviations from normal values. They should be as close to each other.
How to measure network speed
You will need
  • program to calculate the speed of the local network.
Instruction
1
Provide the necessary conditions for measuring the speed of your local network. To do this, shut down the applications that in any way involves traffic. This is necessary in order to avoid inaccuracies when measuring. Close programs that use your PC resources to a large extent, as performance is also largely can affect the speed of data transmission and reception. Configure firewalls so that they do not interfere with the passage of the stream of test information through the local network.
2
Download a special program to measure the speed of local network. You can use your regular applications running in the portable or installed, and the console utility. In the first case, programs are usually part of others, such as AIDA. It includes a special utility which performs speed measurement and displays the results in graphs. You can download it from official developer's website and install on two computers connected by a network, and then perform necessary actions to calculate speed.
3
If you do not want to install additional software to measure the speed of local network, use the console utilities. For example, iperf, Netspeed, PCATTCP, NetCPS, and so on. They all work on the same principle and have a set of specific commands that you need to know to perform a measurement of the speed of your local network. Usually their work is built on the file transfer size 10-100 megabytes for convenience, then the calculations are done automatically, reducing errors to a minimum. You can also calculate the speed yourself, but there will be inaccuracies.
Useful advice
Use when measuring manually the files integer.
