How To Configure Lan Network Windows 11

People are currently reading this guide.

Alright, let's dive into setting up your Local Area Network (LAN) on Windows 11! It might seem a bit technical at first, but if you follow these steps carefully, you'll have your devices chatting with each other in no time.

Getting Started: What Do You Need?

Before we jump into the configuration, let's make sure you have all the necessary ingredients for this digital recipe.

Network Adapters: Ensure each computer you want to connect to the LAN has a working Ethernet port or Wi-Fi adapter. Most modern computers come with these built-in.
Network Cables (Ethernet): If you're going for a wired LAN, you'll need Ethernet cables (RJ45 connectors) long enough to connect your devices to a central networking device. Cat 5e or higher cables are recommended for good performance.
Router or Switch: This is the central hub of your wired network. A router is generally used for home networks as it also provides internet access. A switch is primarily for connecting devices within the same network. For wireless connections, a wireless router is essential.
Internet Connection (Optional but Likely): If you want your LAN to have internet access, you'll need a modem connected to your router.

Step 1: Connecting Your Devices Physically

Let's get those physical connections sorted out first.

For a Wired LAN:

Take one end of an Ethernet cable and plug it into the Ethernet port on your first computer. You should see a small light illuminate on the port indicating a connection.
Take the other end of the same cable and plug it into an available LAN port on your router or switch. These ports are usually labeled "LAN" and are distinct from the "WAN" or "Internet" port on a router.
Repeat this process for each additional computer or device you want to include in your wired LAN.

For a Wireless LAN:

Ensure your wireless router is powered on and broadcasting a Wi-Fi signal.
On each Windows 11 computer, click on the Wi-Fi icon in the system tray (usually in the bottom right corner of your screen).
A list of available Wi-Fi networks will appear. Find the name (SSID) of your wireless network and click on it.
If prompted, enter the network password (also known as the Wi-Fi key or security key) and click "Connect."

Step 2: Configuring Network Settings on Windows 11

Now that your devices are physically connected (or wirelessly linked), let's configure the network settings within Windows 11.

Accessing Network and Sharing Center:

Click on the Start Menu (the Windows icon in the bottom left corner).
Type "Control Panel" and press Enter.
In the Control Panel, click on "Network and Internet".
Then, click on "Network and Sharing Center".

Configuring Adapter Settings:

In the Network and Sharing Center, on the left-hand side, click on "Change adapter settings". This will open a window showing your network adapters (e.g., Ethernet, Wi-Fi).
Identify the network adapter you are currently using for your LAN connection (it will likely say "Ethernet" if you are wired or the name of your Wi-Fi network if you are wireless).

Setting IP Address and DNS (Usually Automatic):

For most home and small office networks, you'll want to use Dynamic Host Configuration Protocol (DHCP). This means your router automatically assigns IP addresses and other network configurations to your devices. Here's how to ensure it's enabled:

Right-click on your active network adapter (Ethernet or Wi-Fi) and select "Properties".
In the properties window, scroll down and find "Internet Protocol Version 4 (TCP/IPv4)". Select it and click on the "Properties" button.
In the TCP/IPv4 Properties window, make sure that both "Obtain an IP address automatically" and "Obtain DNS server address automatically" are selected. This is the default and recommended setting for most users.
Click "OK" on both windows to save the changes.

(Optional) Setting a Static IP Address:

In some advanced scenarios, you might want to assign a static IP address to a particular computer (e.g., for hosting a server or printer). If you need to do this:

Follow steps 1 and 2 above to open the TCP/IPv4 Properties.
Select "Use the following IP address:" and "Use the following DNS server addresses:".
Enter the desired IP address, Subnet mask, and Default gateway. You'll need to know the IP address range of your network and ensure the IP address you choose is not already in use.
Enter the preferred and alternate DNS server addresses (you can often use your router's IP address as the preferred DNS server or use public DNS servers like Google's (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1 and 1.0.0.1)).
Click "OK" on both windows to save the changes. Be cautious when setting static IP addresses if you are unsure about your network configuration.

Step 3: Enabling Network Discovery and File and Printer Sharing

To allow your computers to see each other on the network and share files and printers, you need to enable network discovery and file and printer sharing.

Go back to the Network and Sharing Center (Control Panel > Network and Internet > Network and Sharing Center).
Click on "Change advanced sharing settings" on the left-hand side.
You will see different network profiles (Private, Guest or Public, All Networks). Expand the profile that best suits your network (usually "Private (current profile)" for a home or trusted network).
Under "Network discovery", select "Turn on network discovery".
Under "File and printer sharing", select "Turn on file and printer sharing".
Scroll down to "Password protected sharing". You have two options here:
- Turn on password protected sharing: This requires users on other computers to have a user account and password on your computer to access shared resources. This is generally more secure.
- Turn off password protected sharing: This allows anyone on the network to access shared resources without a password. This is less secure but can be more convenient for a trusted home network.
Expand "All Networks".
Under "Public folder sharing", you can choose whether or not to allow anyone on the network to access files in your Public folders.
Click "Save changes" at the bottom.

Step 4: Sharing Folders and Printers

Now that network discovery and file and printer sharing are enabled, you can choose specific folders and printers to share.

Sharing Folders:

Open File Explorer.
Right-click on the folder you want to share.
Hover over "Give access to" and then select "Specific people...".
In the File Sharing window, you can add specific users or groups (like "Everyone").
For each user or group, you can set the permission level (Read, Read/Write).
Click "Share" and then "Done".
The shared folder will now be accessible to other computers on your LAN under the "Network" section in File Explorer.

Sharing Printers:

Go back to the Control Panel and click on "Devices and Printers".
Right-click on the printer you want to share.
Select "Printer properties".
Go to the "Sharing" tab.
Check the box next to "Share this printer".
You can enter a share name for the printer (optional).
Click "Apply" and then "OK".
Other computers on your LAN can now add this printer by going to "Devices and Printers" and clicking on "Add a printer". They should be able to find the shared printer on the network.

Step 5: Testing Your LAN Connection

To ensure everything is working correctly, try accessing shared resources from another computer on your LAN.

Open File Explorer on another computer connected to your LAN.
In the left-hand pane, click on "Network".
You should see the names of the other computers on your network.
Double-click on a computer name to view its shared folders and printers.
Try opening a shared folder or printing a test page to the shared printer.

Congratulations! You've now configured a LAN network on Windows 11. This setup allows your devices to communicate, share files, and even printers.
