How to Create a LAN Network




It’s easy to turn on your wireless router and start sharing the Internet connection it provides with the various devices in your home or office, but sometimes you want to create your own private network that doesn’t rely on an internet connection. 

This is what a local area network (LAN) does; it creates a closed network inside your house or office building. Here’s how to set one up using inexpensive equipment you may already have at home.


What is a LAN?

A LAN is a network that uses the same type of cable and connectors as Ethernet. A typical office building would have an Ethernet cable running from each room to the office’s wiring closet, where it connects to the company’s router. 

In this setup, all computers in the office can share resources like printers on the company’s network. 

A wireless connection is also possible by connecting laptops and other devices directly to the router via Wi-Fi or Bluetooth. This setup is more commonly found in homes with Wi-Fi networks or in small businesses with only one or two rooms. With a single computer connected to the router, you might need an additional adapter so that multiple computers can connect to your network. These adapters are called wired routers. 

Wired networks are usually cheaper than wireless ones because they use less power and don't require any extra adapters or configuration; however, they're limited to the length of their cables. 

Wireless connections are useful when you want to move around freely without being tied down, but they do cost more up front. 

If you want to create a home network using ethernet cables, follow these steps: first find out how many ports (ports are sockets for different types of cables) your modem has. You'll need one port per device or laptop which will be accessing the internet over ethernet cables (usually four ports). 

Next buy enough ethernet cables to go between the modem and each device plus extras if you think some will be needed later for new devices such as tablets, smart TVs etc., then buy a router if there isn't already one present on the property. Connect the cables according to instructions.

Plug everything in and turn them on at the wall socket. Open the browser address bar and enter 192.168.1 - it should show something similar to 192.168.1/manage. The default username/password combination should be admin/admin - change them before going live!


The Benefits of a LAN

Setting up a local area network is one of the best things you can do for your business. It allows you to share files, printers, and other devices with the people in your building. The benefits are huge:

-You get to work faster. You don't have to go home or use the internet when you need something from another desk because everything is right there.

-You save money on office space and rent. You don't have to worry about using precious square footage for storage or printing equipment because it's all on your desk.

-It's easier than ever before! Nowadays all you need is an Ethernet cable, some laptops, and an operating system (or two) installed on them. Setting up a LAN doesn't take much time at all! -First, identify the cables that need to be hooked up together. 

In most cases this will just be two—one going from each laptop computer to a switch. 

-Second, plug one end of each cable into the correct port on both computers. 

-Third, connect an Ethernet cord from the switch to any available port on your router or modem if you have either one set up in your office already. 

-Fourth, if it's not automatically detected by Windows 7/8 then download and install drivers for whichever operating system is running on both computers so that they'll be able to communicate properly with each other and the rest of your network. -Fifth, make sure that the connection between the switch and router or modem is working correctly. 

On newer models this may happen automatically once you plug in the second cable between the two. If not, click Start, type ncpa.cpl without quotes into the search box, hit enter to open up Network Connections, click on your current connection type (most likely Local Area Connection), highlight it by clicking it once, and click Properties. Choose Internet Protocol Version 4 from under This connection uses the following items, choose Obtain an IP address automatically from under Obtain DNS server address automatically, and then choose OK twice to close out of both windows.]


Creating a LAN

Creating a Local Area Network (LAN) is the process of linking two or more computers together so that they can share files and hardware. It is also known as networked computing. LANs are used in organizations, homes, schools and businesses.

A LAN can be created using either cables or wireless connections. There are three types of cabling that can be used to create a network: twisted pair, coaxial, and fiber optic cable. Twisted-pair wire comes in several different varieties including Cat 3 for use with 10Mbps Ethernet networks; Cat 5 for use with 100Mbps networks; and Cat 5e for 1000Mbps networks. 


Coaxial cable is typically used with broadband Internet service providers such as cable TV companies or satellite providers. Fiber optic cable offers very high data transmission speeds and can be broken into lengths up to 328 feet (100 meters). 

To create a LAN using wireless networking you need an access point. To establish this type of connection your devices must have Wi-Fi capability built in. 


The access point acts like a bridge, transmitting data between devices on the local area network and outside devices via an internet connection. If you want your device to connect with other outside devices you will need an ISP, which stands for Internet Service Provider. These are most often cable TV companies or satellite providers. 


You'll also need a modem to transmit the information from your router to the outside world. Your router is the central hub for all information entering and leaving your home network. Routers come in many shapes and sizes, but all do basically the same thing: convert digital signals from one form to another. 


They can send radio waves over the airwaves, convert electricity into radio waves or translate light pulses onto wires just like modems do with sound waves sent down telephone lines. Wireless routers typically cost less than wired routers because they don't require additional hardware such as cables. Wireless routers can be placed anywhere within range of the desired signal. 


Most models feature antennas that can be adjusted to optimize performance based on distance from the access point. Some models offer both long-range antennae for larger spaces and short-range antennae for smaller spaces. Higher quality antennas are available separately if needed. 


Most routers also allow customization of security settings such as passwords and encryption keys to protect against unauthorized access. Older models were only able to handle simplex transmissions, which means information can only go one way at a time. Newer models are capable of handling half duplex and full duplex transmissions meaning multiple parties can talk at once without interrupting each other. 


As well as frequency bandwidth, these newer routers also support modulation types such as Single-Carrier Frequency Division Multiple Access (SC-FDMA), Orthogonal Frequency Division Multiplexing (OFDM), Code Division Multiple Access (CDMA), Time Division Multiplexing(TDM), and others. Another distinction is whether the router uses a serial or parallel port. Parallel ports are faster and can carry more data, while serial ports are cheaper and require fewer resources. 

Serial ports also transmit the data one bit at a time, while parallel transmits bits simultaneously. This is important when transferring large files. Finally, routers can be equipped with extra features such as Quality of Service (QoS), Dynamic Host Configuration Protocol (DHCP), network address translation (NAT), and firewalls to prevent attacks on your LAN.

These devices are usually sold in electronics stores or online by manufacturers. Be sure to compare prices before purchasing as some brands may be priced higher due to added features or company reputation. 


Once you decide on a router, be sure to check its compatibility with your wireless devices and your computer operating system. For instance, some models may only work with Windows XP and not Vista or 7. Others may be compatible with Macs as well as PCs. 


This is especially important if you plan on using the router to share an Internet connection. routers may only work with certain models of desktop computers. 

LAN networks can also be established with a wired router and an access point. Wired routers are designed to transfer data from one computer to another, rather than sending data through the air as a wireless router does. 


In this scenario, a connection is established between two devices via an Ethernet cable or coaxial wire. To create a LAN network you need to make sure the devices on your network are connected to the router and/or access point using appropriate equipment such as Ethernet cables or coaxial wires. 


All information from your computer is transferred through the access point, then transmitted across the wireless spectrum to other devices on your network.


Configuring Your Router

To configure your router, you'll need to log in. You can do this by entering the router's IP address into your browser's address bar. If there is no default login ID or password, try admin and admin as a username and password. 

Once you've logged in, you can change the settings of your router. In the WAN Setup menu, you'll see an option for Connection Type. 


From here, select PPPoE. Then enter your user name and password from your ISP (your ISP will provide these). Next, click on Apply Settings. And that's it! The next time you connect to your WiFi network, you'll be connected to the Internet through your new DSL connection. 


Now we just have to get our computers talking to each other. We can accomplish this using Windows' built-in sharing feature. On one computer, open the Control Panel and choose Network Sharing Center. 


From here, choose Set Up a Home or Small Office Network at left side of screen and then follow instructions to set up the shared folder(s) with read/write permissions. For example: I'm going to create a folder called Jill which all users on my home network will be able to read and write files in. 


Now every computer on my home network should show Jill as a shared drive when they go back into their My Computer window. But how do I access this drive from my laptop? Well, first make sure that your wireless card is enabled and has a strong signal. Then open the Wireless icon in System Tray (the lower right corner of your screen) and choose Connect to Wireless Network. Pick the name of your home wireless network and enter its key if necessary. 


Click Connect to complete setup. Now you should have full internet access wherever you are inside the house! When any device connects to the wired or wireless network, it will receive a gateway address automatically. 


However, only devices plugged into the same switch port will share resources. So what's stopping me from plugging my phone charger into any outlet and having internet on my phone? Good question! Make sure your outlets are properly labeled before plugging anything in. Also make sure that your cables aren't interfering with power lines. Powerlines can interfere with WiFi networks so try to keep them out of sight whenever possible. 

What about file sharing between devices? Well, one way is by connecting both devices via USB cable or over Bluetooth but not everyone has those options available to them so let's take a look at some alternatives... There are also several cloud storage providers available including Google Drive, Dropbox, iCloud, OneDrive and more.


 These services allow you to upload important documents like presentations and spreadsheets or photos onto the web so anyone with an internet connection can access them. You may want to explore some of these services if file-sharing between devices isn't working for you.

Assigning IP Addresses

A LAN network is a group of computers that are connected together through either an Ethernet cable or wireless router. 


When computers are connected to one another in this way, they can share files and use resources on the other computers. It's important to assign IP addresses so that each computer can communicate with the others on the network. 


Otherwise, they'll just be able to communicate with the device they're directly plugged into. To assign an IP address, you need only access your router's settings and look for something labeled DHCP or assign static IP. From there, you should be able to input your desired information and save it for future use. 

1) Look at your router's settings for DHCP or assign static IP. 


2) Input your desired information and save it for future use. 

3) You may also want to change your DNS servers by going back to those same settings

 4) You will then see two fields: 


5) Primary DNS server and 


6) Secondary DNS server


7) You will want to put numbers here which correspond with the number of Google servers you have listed


 8).Take care not to list all 8 of them, as if you do too many, your internet speed could suffer greatly 


9). Finally, make sure that all computers connected on the network are set up identically 


10). If not, these discrepancies may cause some problems. For example, imagine that one person puts lan as their name while someone else inputs school. 


There would be no way to find the right person unless you knew exactly what email was used. Even though the names are technically different, the IP addresses would still match and allow both people access to each other's networks.


 There are several ways around this problem but we won't go into detail about any of them because we don't want you getting any more confused than necessary!


Testing Your Connection

If you're having trouble with the connection, start by testing your connection. To do this, plug one end of an Ethernet cable into the network port on your desktop computer and the other end into one of the ports on your router. 


Once this is done, use another Ethernet cable to connect one of the ports on your router to any available port on your modem. If there are no open ports, try using an open USB port instead. You should now have two cables connected - one from your computer to your router and another from your router to either the modem or another device.


Open your browser, type 192.168.1.1 (or whatever your default IP address may be) in the URL bar, and hit enter on your keyboard to load the login page for your router's configuration page (). Type in admin as both username and password (), then click Login (). 

Then click Wireless tab () located at top right corner of window, find WiFi Settings (), select Use One Device Only () then Apply () at bottom right corner of window (). The only way to change this setting is to disable it first then enable it again which can only be accomplished through that wireless tab interface option mentioned earlier. Otherwise, if you want to change this setting 


without disabling it first, simply switch back over to the Basic Wireless Setup tab and uncheck the box next to Use One Device Only. Finally, press Apply at bottom right corner of window and wait for confirmation before closing router settings (). 


Make sure to restart your computer after logging out of the router configuration page. When finished, check to make sure all wired connections are secure and working properly. Unplug one of the ethernet cables and test it by plugging it back in to ensure a solid connection. It is also recommended that you periodically monitor your internet speed every few hours to ensure uninterrupted service. 


It will take some time before data packets fully transmit due to fluctuations in internet connectivity, but with enough time elapsed, you will notice improvement in terms of data transmission quality. Remember not to walk away from the computer while monitoring internet speeds because if there's a problem during transmission, it will stop immediately once left unattended.
