Creating a local area network to connect multiple computers is a basic but critical task for the modern home or small office. Router It acts as a central hub that not only provides access to the global internet but also allows devices to exchange data with each other at high speed. Proper organization of such a structure eliminates file transfer issues and ensures stable operation of all connected devices.
You don't need to be a certified network engineer to perform this procedure. Modern routers from brands such as TP-Link, Asus or Keenetic, are equipped with an intuitive web interface that guides the user through all setup steps in minutes. The key is to follow the steps consistently and understand the operating logic of the network equipment.
In this article, we'll cover the physical connection of cables, accessing the control panel, and configuring traffic distribution settings in detail. You'll learn how to differentiate ports and understand what a DHCP server, and you can easily expand your home network by adding new computers or laptops.
Equipment preparation and check of completeness
Before you begin assembling your network, you need to ensure you have all the necessary components. A basic kit includes the router itself, a power supply, and typically one patch cord (network cable). However, if you plan to connect desktop computers via wire, one cable may not be enough, and you'll need to purchase additional twisted-pair cables of the required length.
Take a look at the back panel of your device. There you will see several connectors labeled as WAN (or Internet) and a group of four connectors LANThe LAN ports are where we'll connect the cables going to the computers. The WAN port is intended exclusively for the incoming cable from the ISP.
⚠️ Attention: Never plug the ISP cable into the LAN ports or the computer cable into the WAN port. This is a common mistake that will prevent the network from working, even if all settings are correct.
It's also worth checking the condition of the antennas if your model is external. They should be carefully screwed onto the corresponding connectors on the case until they are secure. Antennas are essential for Wi-Fi operation; otherwise, the coverage area will be minimal and the connection speed will be unstable.
☑️ Pre-launch check
Physically connecting cables and starting the system
Start by connecting the power supply. Insert the power adapter into the corresponding jack on the back of the router and plug it into a power outlet. Then press the power button if it's not aligned with the power supply. The indicators on the front panel should light up, indicating that the router's operating system has begun loading.
Next, take the cable that your internet provider provided you with (it may come directly to your apartment or through a modem) and plug it into the blue port labeled as WAN or InternetThis port's color is usually different from the others, which helps avoid confusion. If the WAN indicator lights up or blinks, physical contact with the external network has been established.
Now let's move on to connecting the computers. Take a patch cord and connect the network card of the first computer to any of the yellow ports. LANA distinctive click when the plug is inserted confirms it is securely seated. Connect the second and third computers in the same manner to available LAN ports 2, 3, and 4, respectively.
If the number of computers exceeds the number of ports on the router (usually four), you'll need an additional network switch. The router's cable is plugged into the switch, and then distributed to the remaining computers. This allows you to scale your network to dozens of devices.
Login to the web interface and initial setup
Once all the cables are connected, you need to access the router settings. To do this, open a browser on any connected computer and enter the device's IP address in the address bar. By default, this is most often 192.168.0.1 or 192.168.1.1The exact address, as well as the login and password, are indicated on the sticker on the bottom of the router.
The system will ask for authorization. The default credentials are usually a combination of admin/admin or admin/passwordIf you have previously changed your password and have forgotten it, you will have to perform a factory reset (Hard Reset) by holding down the button Reset on the body for 10-15 seconds.
Once you've opened the control panel, you'll see the main page displaying your connection status. Here, it's important to ensure that your router has received an IP address from your ISP. In some cases, you may need to clone your MAC address or select the connection type (PPPoE, L2TP, or Dynamic IP) provided by your ISP.
What should I do if the settings page doesn't open?
Make sure your computer's network card is set to obtain an IP address automatically (DHCP). If a static address from a different subnet is assigned, access to the router interface will be impossible.
Setting up a wireless Wi-Fi network for laptops
To connect mobile devices and laptops wirelessly, you need to configure the wireless module. Find the section in the menu Wireless or Wi-FiHere you are asked to set a network name (SSID), which will be displayed in the list of available connections on your devices.
Setting up security is a critical step. Choose the encryption type. WPA2-PSK (or WPA3, if your equipment is modern) and create a strong password. Using an open network or outdated WEP encryption makes your data vulnerable to interception by neighbors or hackers.
It's also recommended to separate frequency bands if your router is dual-band. You can create two networks with the same name for Seamless Roaming, or different names, for example, HomeWiFi_2.4 And HomeWiFi_5GThe 5 GHz band provides speed but has a shorter range, while 2.4 GHz is better at penetrating walls.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID (Network Name) | Unique name | The name visible when searching for networks |
| Security mode | WPA2-PSK / AES | Data encryption standard |
| Channel | Auto / 1, 6, 11 | Signal broadcast frequency |
| Channel width | 20/40 MHz | Affects speed and stability |
Distributing IP addresses via a DHCP server
In order for each computer on the network to have its own unique address and to be able to function properly, the router must be activated DHCP serverThis component automatically assigns IP addresses to connected devices from a specified pool. Manually setting up static IP addresses on each PC is not necessary if you're using a home network.
In the LAN settings you can see the address range, for example, from 192.168.1.2 to 192.168.1.254The router will automatically take the first address (usually .1) and assign available numbers to the remaining devices. This ensures that there are no addressing conflicts when two devices attempt to use the same IP address.
If you're connecting specific equipment that requires a permanent address (such as a network printer or IP camera), you can use IP binding by MAC address. This ensures that the router will always assign the same address to the same device, even after a reboot.
Checking the connection and diagnosing problems
After completing the settings, you need to check the network functionality. On a computer with an operating system Windows Open command prompt and enter the command ping 192.168.1.1 (or your router IP). A response from the server with a response time (time) indicates a healthy physical and logical connection.
Next, check your internet access. Open your browser and try loading a few websites. If the pages don't load, but your local network is working, the problem may be with your ISP or WAN settings. Check the indicators on your router: a blinking WAN indicator indicates data transfer.
A common problem is when computers see the router but not each other. Make sure the Windows network profile is set to "Private" or "Home" rather than "Public" in your settings. For security reasons, the system blocks other devices from being discovered when using a public profile.
⚠️ Attention: Router interfaces may vary from manufacturer to manufacturer. If you can't find a specific option, consult your model's documentation or look for screenshots of the interface for your firmware version.
Frequently Asked Questions (FAQ)
Is it possible to connect two routers to one provider cable?
Technically, it's impossible to directly connect two routers to a single ISP cable, as the ISP typically only assigns one IP address. However, you can configure the second router in Access Point mode and connect it via cable to the first router. This will expand the Wi-Fi coverage area and the number of available LAN ports.
Why does the computer see the network, but says "No Internet access"?
This could indicate incorrect DNS settings, issues with network card drivers, or a lack of authorization with your ISP (requiring you to enter your PPPoE login and password in the router). Also, check if your data plan has expired.
How many computers can be connected to one router?
Home routers typically support 10 to 30 active devices simultaneously without performance degradation. More powerful models for small offices can handle 50 or more connections. However, the actual internet speed will be shared among all active users.
Do I need to configure each computer separately?
In most cases, no. If your computers' network cards are set to obtain an IP address automatically (DHCP), they will configure themselves immediately after connecting the cable or entering the Wi-Fi password. Manual configuration is only required on specific corporate networks or for older devices.
