Modern apartments with thick walls or complex layouts often have areas where the main router's signal simply doesn't reach. A solution to this problem may be to use an older, but reliable, router. D-Link DIR-320 As a wireless extender. Despite its age, this device offers excellent stability and supports the necessary features for extending network coverage.
Before you begin setting up, you need to understand that the process of turning a router into a repeater requires precise execution of a sequence of actions. Control interface The details may vary depending on the firmware version, but the basic principles remain the same. You'll need access to the device's web interface and some basic knowledge of IP address settings.
In this article, we will examine the connection process in detail. DIR-320 to another router via Wi-Fi. We'll cover WAN settings, working with MAC addresses, and the specifics of wireless bridges. Proper configuration will allow you to leverage the potential of your old equipment to boost the signal in remote rooms.
Equipment preparation and compatibility testing
The first step is to physically prepare the device. You need to make sure that D-Link DIR-320 is working properly and reset to factory settings. This will eliminate any configuration conflicts that may have remained from previous use. The reset is performed by holding down the button. Reset on the rear panel for 10-15 seconds with the power on.
It's important to understand that not all firmware versions support client mode or WDS out of the box. In some cases, updating the software to the latest version from the manufacturer's official website may be necessary. Firmware — is the foundation on which all network functions are built.
⚠️ Important: Before updating the firmware, be sure to check the hardware revision (indicated on the sticker on the bottom of the device, for example, A1 or B1). Installing incorrect software may cause irreversible damage to the device.
For initial setup, connect your computer to any LAN port. DIR-320 Using a cable. A Wi-Fi connection is not recommended at this stage, as it may become unstable while changing settings. Once connected, make sure your PC has received an IP address automatically or has a static address on the subnet. 192.168.0.x.
Login to the control panel and basic LAN setup
Open any web browser and in the address bar enter the default IP address of the router, usually it is 192.168.0.1If the address has been changed previously, use the one that is relevant for your device. In the authorization window, enter your login and password (the default is often admin for both fields).
After successful login, the first thing you need to do is change the IP address of the DIR-320This is a critical step to avoid address conflicts with the main router you plan to connect to. If the main router has an address 192.168.0.1, then DIR-320 needs to be set, for example, 192.168.0.254.
Find the section Network or LAN in the settings menu. Change the IP address to one that is free on your network. Also, make sure the subnet mask matches the main router, which is usually 255.255.255.0After applying the settings, the router will ask you to reboot, and you will need to access it using the new address.
☑️ Preparing the DIR-320
Setting up wireless mode
The next step is to configure the wireless module. Go to the section Wireless or Wi-FiHere, you need to set the network name (SSID) and password, which will be identical to the settings of the main router if you want to create a single network with seamless transition (although full roaming requires a controller; in the DIR-320 bundle, this is simply cloning the parameters).
Please pay attention to the channel selection. For stable operation in repeater mode, the channels of the main router and DIR-320 must match. It is recommended to use a static channel (e.g. 1, 6 or 11) rather than the Autoto avoid connection breaks when reconnecting.
In the security settings, select the encryption type WPA2-PSKThis is the most secure and compatible standard. Make sure the passphrase matches the main network password character for character. Any error will result in the inability to establish a connection between devices.
WAN Configuration and Operation Mode (Client or WDS)
The most difficult part is choosing the correct operating mode. Depending on the firmware version, you need to find the section WAN or InternetHere you should create a new connection. The connection type is selected depending on the capabilities: Dynamic IP (for client mode) or special modes WDS / Bridge.
If your firmware supports the mode Client (Client) in the wireless network settings, select it. In this mode, the router connects to another router's Wi-Fi like a regular device and shares the internet through its LAN ports and its Wi-Fi. If you don't see this mode, check the settings. WDS (Wireless Distribution System).
In WDS mode, you need to specify the MAC address of the main router. To do this, go to the wireless network status of the main router, copy its MAC address, and paste it into the corresponding WDS settings field. DIR-320You also need to enter the DIR-320's MAC address on the main router (if it's also a D-Link or supports WDS).
What is the difference between Client and WDS mode?
Client mode creates a separate subnet (NAT); devices behind the DIR-320 will see the internet, but may not see devices behind the main router. WDS (Bridge) combines networks into a single segment, allowing all devices to "see" each other as if they were connected by cable.
Disabling the DHCP server
One of the most common mistakes when creating a dual-router network is running two DHCP servers simultaneously. This leads to IP address conflicts and a complete loss of internet access for connected devices. DIR-320, which will work as a repeater, the DHCP server must be disabled.
Find the section in the menu LAN or Network Settings and find the subsection DHCP Server. Set the switch to the position Disable or uncheck the box EnableAfter this, save the settings. Now only the main router will distribute addresses.
After disabling DHCP, you may need to restart your computer or refresh its network settings (command ipconfig /renew in Windows) to get the correct address from the main router via DIR-320.
| Parameter | Main router | DIR-320 (Repeater) | Status |
|---|---|---|---|
| IP address | 192.168.0.1 | 192.168.0.254 | Different |
| DHCP Server | On | Turned off | One active |
| SSID (Wi-Fi Name) | MyHome | MyHome | Same |
| Wi-Fi channel | 6 | 6 | Matches |
Completing setup and checking the connection
After making all changes, you must reboot. DIR-320Wait until the system fully boots up (the indicators should light up normally). Now try connecting a wireless device (smartphone or laptop) to the network that the DIR-320 is now relaying.
Check the connection status. If everything is configured correctly, the WAN or WLAN indicator on the DIR-320 should show data activity. You can check the IP address assigned to your phone: if it is within range of the main router (e.g., 192.168.0.x), which means the network is working correctly.
For diagnostics, you can use the command pingOpen the command line on your PC and try pinging the main router's address through the connection to the DIR-320. No packet loss (0% loss) indicates a high-quality wireless bridge.
⚠️ Please note: The connection speed in Wi-Fi repeater mode will always be lower than with a direct connection or via cable. This is because the radio module operates in half-duplex mode, receiving and transmitting data alternately.
Possible problems and their solutions
During setup, users often encounter problems with devices being unable to obtain an IP address. First, check whether DHCP is truly disabled on the DIR-320. Also, ensure that the MAC address filter on the main router isn't blocking the extender's connection.
If your connection speed is extremely slow, try changing your wireless network channel to a less crowded one. Use dedicated Wi-Fi network analysis apps on your smartphone to find a free frequency band. Interference from neighboring networks is a common cause of instability.
In some cases, changing the wireless network operating mode helps 802.11 b/g/n mixed to a specific standard, for example, only 802.11n, if all your devices support this standard. This can improve connection stability.
Is it possible to connect routers of different brands via WDS?
Technically, the WDS standard isn't strictly unified. Bridges often only work reliably between devices of the same brand (D-Link to D-Link). When connecting devices of different brands (for example, D-Link and TP-Link), the "Client" or "Universal Repeater" mode is more often used, if supported by the firmware.
Will my internet speed decrease when using DIR-320?
Yes, when connecting via Wi-Fi, speeds can drop to 50% or more of the main channel's speed, as the airwaves are split between receiving and transmitting. For mission-critical tasks, it's better to use a cable connection between routers, if possible.
What should I do if I forgot my DIR-320 password after setup?
The only reliable way is to perform a hard reset. Find the reset hole on the case, press it with a paperclip, and hold it for about 10-15 seconds until the lights flash. The router will return to factory settings, and you'll be able to log in with the default password.
