How to Use the D-Link DIR-320 as a Wi-Fi Access Point: A Complete Guide

Router D-Link DIR-320 — a popular model that remains in demand even after years due to its reliability and flexibility. Many users don't know that this device can be used not only as a classic router, but also as a Wi-Fi hotspot To expand network coverage. This mode is useful if you already have a primary router (for example, from your provider), but need to improve the signal in remote rooms or connect devices via cable through additional ports.

In this article we will look at three key scenarios: connection DIR-320 to the existing network via cable (mode Access Point), setting up a wireless bridge (WDS) and solutions to typical problems that arise when converting a router into an access point. We will pay special attention to security — how to avoid IP address conflicts and protect your extended network from unauthorized access.

If you've never encountered these settings before, don't worry. The instructions are tailored for beginners, with step-by-step screenshots and explanations of each parameter. For experienced users, here's a quick guide. unique technical nuances, which are rarely mentioned in standard manuals (for example, how to manually set VLAN to isolate traffic or disable DHCP without loss of functionality).

Why turn the DIR-320 into an access point?

Before we move on to the settings, let's figure out in which cases this mode is justified:

• 📶 Increasing Wi-Fi coverageThe main router doesn't reach remote rooms, and cable installation is impossible.
• 🖥️ Connecting wired devicesDo you have? Smart TV, a gaming console or a PC without a Wi-Fi adapter, but all ports on the main router are occupied.
• 🔄 Replacement of obsolete equipment. DIR-320 It can work as a budget repeater if its capabilities as a router are no longer relevant.
• 🛡️ Creating a guest networkAn isolated access point for visitors to avoid revealing the main network password.

It is important to understand the difference between the modes:

Key takeaway: If it is possible to lay a cable, always choose the mode access points (AP)This ensures minimal speed loss and maximum reliability. Wireless solutions (WDS (or repeater) should only be considered as a temporary solution or for areas where cable installation is not possible.

Preparing the Router: Resetting and Physical Connection

Before setting up, you need to return DIR-320 to factory settings. This will prevent conflicts with previous configurations. To reset:

1. Connect the router to the network.
2. Find the button on the back panel Reset (usually recessed into the body).
3. Press and hold it 10-15 seconds (until the indicators start flashing).
4. Wait for the reboot (about 1-2 minutes).

After the reset, connect to the router:

• By cable: use the port LAN on DIR-320 and the PC network card.
• On Wi-Fi: Find the network with the name dlink (without password) or dlink-XXXX (the password is on the sticker).

⚠️ Attention: If after resetting the router does not respond to 192.168.0.1, check the network card settings on your PC. It should be configured to automatic IP acquisition (DHCP). Manually enter the address 192.168.0.X Not recommended - this may cause conflicts later.

To enter the control panel:

1. Open your browser and go to the address http://192.168.0.1.
2. Enter your login and password (default - admin/admin or an empty password; see the sticker on the router).
3. If the page doesn't open, try http://dlinkrouter.local or http://192.168.1.1 (depending on the firmware version).

Setting up the DIR-320 in access point mode (via cable)

This is the most reliable way to use it. DIR-320 as access points. Follow the instructions:

1. Disable the DHCP server:

   Go to Setup → Network Settings.

   In the section DHCP Server check the box Disable.

   Save settings (Save Settings).

2. Set up an IP address:

   In the same section (Network Settings) find the field Router IP Address.

   Set a static IP that does not conflict with the main router. For example, if the main router has the address 192.168.1.1, please specify for DIR-320 192.168.1.2.

   The subnet mask must match (usually 255.255.255.0).

3. Connect to the main router:

   Take a network cable and connect one end to the port LAN the main router, and the other one to the port LAN on DIR-320 (do not use the port WAN!).

   If you connect the cable to the port WAN, the router will operate in double NAT mode, which will cause problems with accessing local resources.

4. Set up Wi-Fi:

   Go to Wireless → Basic Settings.

   Please enter the network name (SSID), different from the main router (for example, Home_AP).

   IN Wireless Security select WPA2-PSK and set a strong password (at least 8 characters, with numbers and special characters).

An important nuance: If you want devices to automatically switch between the main router and the access point, use same network name (SSID) and password on both devices. However, in this case, an error may occur roaming (automatic reconnection), which does not always work stably on budget equipment.

Setting up a wireless bridge (WDS) without a cable

If laying a cable is not possible, you can connect DIR-320 with the main router over the air WDSThis mode is more difficult to set up and reduces network speed, but sometimes it is the only possible option.

Conditions for WDS operation:

• 🔄 The main router must support WDS (check in its settings).
• 📶 Both routers must operate on the same frequency (2.4 GHz or 5 GHz).
• 🔐 The Wi-Fi channel on both devices must be fixed (not Auto).
• 🛡️ Encryption type (WPA2-PSK) and password must match.

Step-by-step instructions:

1. On the main router:

   Fix the Wi-Fi channel (for example, 6).

   Enable support WDS (in some routers this mode is called Bridge).

   Add MAC address DIR-320 to the list of allowed devices (you can find the MAC on the sticker or in Status → Device Info).

2. On DIR-320:

   Go to Wireless → WDS.

   Click Survey, find the main router's network and connect to it.

   Specify the same channel and encryption type as on the main router.

   In the field WDS MAC Address Enter the MAC address of the main router.

3. Disable DHCP on DIR-320 (as in AP mode).
4. Save the settings and reboot both devices.

⚠️ Attention: In mode WDS The network speed is halved because the router must simultaneously receive and transmit data. If the main router operates on the standard 802.11n (300 Mbps), real speed through DIR-320 will be ~100–150 Mbit/s.

If the connection is not established:

• Please make sure that the MAC addresses are entered correctly (no spaces or dashes).
• Make sure the channels on both routers match.
• Disable Wi-Fi encryption for the duration of the setup (leaving the network open), then turn it back on.

What to do if WDS is not working?

If the connection fails after completing all the settings, try updating the firmware on the DIR-320. Older firmware versions (especially those from before 2015) may contain bugs in the WDS implementation. Also, check whether the firewall on the primary router is blocking traffic between devices in bridged mode.

Advanced settings: security and optimization

After the basic setup, it is recommended to perform a few additional steps to improve the stability and security of your network.

1. Traffic isolation (VLAN)

If you use DIR-320 To connect guest devices, you can isolate them from the main network:

1. Go to Advanced → VLAN.
2. Create a new one VLAN ID (For example, 10).
3. Bind the ports that will be used by guests to it.
4. In the Wi-Fi settings, specify the same VLAN ID for the guest network.

2. MAC address filtering

To ensure that only authorized devices can connect to your hotspot:

1. Go to Wireless → MAC Filter.
2. Turn on filtering (Enable).
3. Add MAC addresses of trusted devices.
4. Select mode Allow (allow only specified addresses).

3. Optimizing the Wi-Fi channel

To reduce interference from neighboring networks:

• Use the utility Wi-Fi Analyzer (for Android) or inSSIDer (for PC) to find the least congested channel.
• In the settings DIR-320 (Wireless → Basic Settings) lock the selected channel (do not leave Auto).
• If the router supports 40 MHz, enable this mode to increase speed (but it may reduce stability in apartment buildings).

Common errors and how to fix them

Even with proper setup, problems can arise. Let's look at the most common ones:

1. No internet access via hotspot

Causes and solutions:

• 🔌 The cable is connected to the WAN port: Reconnect it to the port LAN.
• 🛡️ IP address conflict: Check that the address DIR-320 is on the same subnet as the main router (for example, 192.168.1.X).
• 🔄 DHCP is not disabled: Make sure that on DIR-320 DHCP server is disabled.
• 🚫 Blocked by firewall: On the main router, check that the firewall is not blocking traffic between devices.

2. Devices do not connect to the Wi-Fi hotspot

Diagnostics:

• 📶 Incorrect password: Check the case of the characters (the password is case sensitive).
• 🔄 SSID conflictIf the network name is the same as the main router, some devices may get confused. Try temporarily renaming the network.
• 🛠️ Outdated firmware: Update your router software via Tools → Firmware.

3. Slow speed or connection interruptions

How to improve:

• 📡 Interference from neighboring networks: Change the Wi-Fi channel to a less crowded one.
• 🔋 Router overheating: Make sure that the ventilation holes are not blocked and that the router is not in an enclosed space.
• 🔄 Incompatible standards: In the Wi-Fi settings, select 802.11n only, if the devices support this standard.

⚠️ Attention: If after setting up in access point mode, access to the web interface is lost DIR-320, connect to it directly via cable and use the static IP you set earlier (eg. 192.168.1.2). Don't try to reset the router—this will return it to router mode, and you'll have to repeat the setup.

Comparison with other modes: which is better?

Access Point Mode (AP) isn't the only way to expand your network. Let's consider the alternatives and their features:

When to choose DIR-320 in AP mode:

• 🏠 In a home or office where cable can be laid.
• 🖥️ You need to connect wired devices (TV, console, PC).
• 📶 Maximum speed and stability required.

When to consider alternatives:

• 🚫 No way to lay a cable - choose WDS.
• 📱 If you need to temporarily boost the signal in one room, the repeater mode will do the trick.
• 🔌 You need to connect a device within Wi-Fi range via cable — use client mode.

FAQ: Frequently asked questions about setting up the DIR-320 as an access point

Is it possible to use the DIR-320 as an access point if the main router is from a provider (for example, from Rostelecom)?

Yes, but two things need to be taken into account:

1. Most ISP routers have this disabled. Bridge mode, That's why DIR-320 will have to be configured as a secondary router (with DHCP disabled).
2. Some providers block access to router settings. In this case, please contact support to unblock it or request login details.

If you can't disable DHCP on your ISP router, set it to DIR-320 a static IP outside the primary router's range. For example, if the primary router distributes addresses with 192.168.1.100 to 192.168.1.200, ask for DIR-320 address 192.168.1.2.

How do I reset the DIR-320 if I forgot the web interface password?

There are two ways:

1. Hard reset:

   Press and hold the button Reset on the back panel 15–20 seconds (until the indicators start flashing quickly).

   After this, the router will return to factory settings (IP: 192.168.0.1, login/password: admin/admin).

2. Reset after 30/30/30 (for older firmware):

   Hold Reset 30 seconds, without releasing, turn off the power for 30 seconds, then turn it back on and hold the button for another 30 seconds.

   This method does not work on all versions. DIR-320, but it may help if the standard reset did not work.

After resetting, all settings, including the Wi-Fi password, will be deleted.

Is it possible to connect an external antenna to the DIR-320 in AP mode to boost the signal?

DIR-320 It doesn't support external antennas—its antennas are soldered onto the board. However, you can improve the signal in other ways:

• Place the router in the center of the coverage area, away from walls and metal objects.
• Use a foil reflector (a homemade "screen") pointed toward the weak signal.
• Update your firmware - new versions may have improved transmission power.
• Place the router on a raised surface (for example, on a cabinet), as the signal spreads better from top to bottom.

If you need a really powerful antenna, consider purchasing a dedicated access point (e.g. TP-Link EAP225).

How can I check that the DIR-320 is operating in access point mode and not as a router?

There are three ways:

1. By IP address:

   Connect to DIR-320 and check your IP (via ipconfig in Windows or ifconfig in Linux). It must belong to the subnet of the main router (for example, 192.168.1.X), not subnets DIR-320 (192.168.0.X).

2. Via the web interface:

   In the settings DIR-320 check that DHCP is disabled and the port WAN not used.

3. By routing:

   Run the command tracert ya.ru in the Windows command line. If the first hop is the IP of the main router, and not DIR-320, then the AP mode is configured correctly.

Can the DIR-320 be used simultaneously as an access point and a router (for different devices)?

Technically yes, but it requires advanced settings and can cause problems:

1. Set up DIR-320 as a router (with DHCP enabled).
2. Connect one of the ports LAN to the main router (as in AP mode).
3. On another port LAN connect the devices that should work through DIR-320 as through a router.

Problems with this solution:

• Devices from different networks will not “see” each other.
• Routing conflicts are possible, especially if IP ranges overlap.
• It is difficult to diagnose problems when the system is unstable.

We recommend avoiding this scheme and using DIR-320 only in one mode.
