In modern apartments or offices, so-called "dead zones" often occur, where the signal from the main router is virtually nonexistent. Reinforced concrete walls, metal structures, and household appliances become a significant obstacle to radio waves. In such situations, users often consider purchasing new, expensive equipment, forgetting about the potential of their existing devices.
Model D-Link DIR-320Despite its age, it remains popular due to its reliable and flexible firmware. This device can function not only as a classic router but also as an access point or repeater. Using an old router as a signal booster is a cost-effective and technically sound solution for expanding network coverage without breaking the bank.
In this article, we will examine the reconfiguration process in detail. router into repeater mode. You'll learn how to properly prepare equipment, change local network settings, and configure a wireless connection so it seamlessly integrates into your existing infrastructure.
Equipment preparation and network diagnostics
Before you begin configuring the software, you need to physically prepare your workspace and analyze your current network situation. You'll need the router itself. D-Link DIR-320, an Ethernet cable (twisted pair), and a computer or laptop for entering settings. It's important to understand that the initial configuration requires a wired connection, as wireless settings may become lost during changes.
First, determine the parameters of your primary network to which the repeater will connect. You will need to know the SSID (network name) and the exact password for the connection. The IP address of the primary network's gateway is also critical, as it will be needed to avoid address conflicts.
⚠️ Important: Make sure your Ethernet cable is working properly. Older cables may only support 10 Mbps, which will bottleneck your entire wireless network, even if your router supports higher speeds.
Check your device's hardware revision. It's on the bottom sticker of the router. DIR-320 may be specified Rev. A1, B1 or NRUThe firmware interface and available functionality depend on this. In some older firmware versions, the repeater mode may be limited or require the installation of alternative software, but standard tools can also achieve the desired result.
Reset settings and enter the control panel
The first step in the reconfiguration process is a complete reset of the router's configuration to factory defaults. This is necessary to remove old routing rules, the DHCP server, and any conflicting entries that may have remained from previous use of the device.
To perform a reset, locate the hole marked on the back panel ResetPlug in the router and wait for it to boot up (about 1 minute). Use a paperclip or a thin needle to press the button inside the hole and hold it for 10-15 seconds. The lights on the front panel should flash or turn off, indicating the recovery process has begun.
☑️ Pre-reset check
After rebooting, connect your computer to any yellow LAN port of the router. D-LinkOpen your web browser and enter the device's default IP address in the address bar. This is usually 192.168.0.1 or 192.168.1.1The exact address is indicated on the sticker on the bottom of the case. To access the admin panel, use the standard credentials: login admin and leave the password field empty (or also admin).
If login is successful, you'll see the main settings menu. The interface may differ depending on the firmware version, but the logic remains the same. It's recommended to immediately change the interface language to Russian if it's not set by default to avoid errors when selecting options.
Changing the IP address of a local network
One of the most common mistakes when creating a network with multiple routers is IP address conflicts. If your main router and DIR-320 will have the same address (for example, both 192.168.0.1), the network will not work. Therefore, you need to change the LAN IP address on the device that will act as a repeater.
Go to the LAN settings section, which is often called Network Settings or Local area networkFind the field IP AddressChange the last digit of the address to a value that is not occupied by other devices. For example, if the main router has the address 192.168.0.1, then for Install DIR-320 192.168.0.250.
| Parameter | Main router | DIR-320 (Repeater) | Comment |
|---|---|---|---|
| IP address | 192.168.0.1 | 192.168.0.250 | Must be in the same subnet |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | Must match |
| Gateway | - | 192.168.0.1 | Main router address |
| DHCP Server | On | Turned off | Critical to operation |
After changing the IP address, the router will ask you to reboot. Please note that after this, you will be unable to access the control panel. The DIR-320 will now be connected to the new address. Save the settings and wait for the device to reboot.
It's also important to enter the gateway and DNS server addresses in the LAN settings. For the gateway, enter the IP address of your main router. This will allow the device DIR-320 knows where to forward Internet requests that it cannot process itself.
Wireless Setup and MAC Cloning
Now let's move on to the most important part - setting up a wireless connection. In the menu D-Link go to the section Wireless or Wi-FiHere you need to enter the network name (SSID) and password. To create a unified namespace (roaming), it is recommended to name the network the same as the main network, but this is not a mandatory requirement for the repeater to work.
The key point is the choice of operating mode. In some firmware versions DIR-320 has an explicit clause Wireless Mode, where you need to choose Client or RepeaterIf there is no such option, the setup is done by linking to an access point. Find the button Site Survey or Search for networks.
From the list of found networks, select your primary Wi-Fi network. The system will prompt you to enter a security key (password). Once successfully connected, the router DIR-320 will receive the Internet from the main device and broadcast it further.
⚠️ Note: Some providers bind internet access to the MAC address of the first device connected. If internet access doesn't appear, use the MAC address cloning feature. Copy the MAC address of the computer that previously connected to the internet into the router's WAN settings. DIR-320.
You also need to disable the DHCP server on DIR-320. This is done in the section LAN or Network SettingsUncheck the box. Enable DHCP ServerOnly one device—the primary router—should be responsible for distributing addresses on your network. If DHCP is left enabled on both devices, the devices will receive incorrect settings and will not be able to connect to the network.
Physical connection and placement of the device
After the software setup, the next step is the physical installation. The Ethernet cable is no longer needed for communication between the routers, as we have set up a wireless connection. Disconnect DIR-320 from the computer and find a place for it in the apartment.
The ideal location for a repeater is a point halfway between the main router and the area where internet coverage is needed. The device should be within range of a strong signal from the main router. If you place the repeater in a "dead zone," it will receive a weak signal and transmit an even weaker one, which will not improve speed.
Indicators on the body The DIR-320 will help you navigate. The indicator is on WAN or a globe icon - this means that the connection with the main router is established. The indicator LAN may light up if a computer is connected to the repeater via a cable.
Avoid placing the router near microwave ovens, baby monitors, and large metal objects. These objects create strong electromagnetic interference that can destabilize the connection, especially at the 2.4 GHz frequency used by this model.
Checking operation and diagnosing problems
After installing the device in the selected location, connect your smartphone or laptop to it. Check your internet access and connection speed. For accurate diagnostics, use utilities like ping or online speed testing services.
Enter the command in the command line of your computer ping 192.168.0.1 (the address of the primary router). If packets are transmitted without loss, the bridge between the devices is functioning correctly. A high ping (more than 50-100 ms within the local network) may indicate severe interference or excessive distance between the routers.
What to do if the speed is low?
Reduce the wireless connection speed in the repeater settings from Auto to a fixed speed (e.g., 54 Mbps). Sometimes, automatic connection speed selection in poor signal conditions causes constant reconnections and packet loss, which reduces overall throughput.
If the devices cannot obtain an IP address, check whether you have disabled DHCP on DIR-320. Also, make sure the Wi-Fi passwords on the primary and secondary routers (if you chose to use different network names) are entered correctly. Even a single character error will result in connection failure.
In some cases, updating the router firmware to the latest available version from the manufacturer's official website can help. This can fix wireless module errors and improve connection stability in client mode.
Frequently Asked Questions (FAQ)
Is it possible to connect DIR-320 to the main router with a cable?
Yes, this is even the preferred option. In this mode, the DIR-320 will function as an access point. You'll need to connect them with a LAN cable (inserting the cable into the main LAN port and the DIR-320's LAN port if DHCP is disabled, or into the WAN port if IPoE/Dynamic IP mode with MAC cloning is configured). Speed and stability will be maximized.
Why did the internet disappear on all devices after setting up the repeater?
Most likely, there is an IP address conflict or two DHCP servers are enabled. Check that the address DIR-320 was different from the main router's address, and make sure that the address distribution function (DHCP) is disabled on it.
Will my internet speed decrease when using a repeater?
Yes, with a wireless connection, speed is reduced by approximately 50% because the radio module cannot simultaneously receive and transmit data on the same frequency. It operates in half-duplex mode. For speed-critical tasks, it's better to use a cable connection between the routers.
Does DIR-320 support 5GHz?
No, model The D-Link DIR-320 operates only in the 2.4 GHz band. This means it can't boost a 5 GHz network signal, but it can broadcast a 2.4 GHz signal from a dual-band primary router.
How to reset the router to its original state?
To do this, simply hold down the button Reset For 10-15 seconds with the power on. All settings, including the Wi-Fi and admin password, will be reset to the factory defaults indicated on the sticker.
