How to set up a Wi-Fi router as an access point

In modern apartments with thick walls or in multi-story office buildings, a single router is often insufficient to cover all rooms with a high-quality signal. The situation where a smartphone in a distant room shows a single network connection, and videos load with constant buffering, is familiar to many. A powerful mesh system or repeater can solve the problem, but a more cost-effective solution is to use an old or additional router in standby mode. access points (Access Point). This method allows you to create a single wireless network with a single name, ensuring seamless roaming between devices.

The advantage of this approach is that you don't have to create a second subnet with its own NAT rules, which often happens when cascading routers via the WAN port. Instead, all devices in the home will be on the same local network, which is critical for operation. smart home, network printers, and media servers. Setup takes only 15-20 minutes and doesn't require in-depth knowledge of network protocols if you follow a clear workflow. The key is to properly prepare the equipment and understand the logic behind IP address allocation.

Before you begin configuring the interface, you need to physically prepare the equipment. You'll need a primary router that already distributes the internet, and a second router that will act as an access point. It's important to understand that the second router will be "dumber": it simply broadcasts the signal, while client management and address assignment remain with the primary device. Therefore, before you begin, make sure you know IP address the main gateway and the password for its administrative panel.

⚠️ Attention: Before connecting cables, disconnect the second router from the main network. Configuration should only be performed with a computer directly connected to the LAN port of the device being configured to avoid IP address conflicts on the network.

Preparing and resetting the second router

The first step is to reset the secondary device to its factory default settings. This is critical, as old configurations, leftover provider settings, or changed passwords can cause unpredictable errors. Locate the button on the device's body. Reset or WPS/ResetIt's usually recessed into the housing, so you'll need a paperclip or toothpick to press it. Hold the button for 10-15 seconds until the lights flash simultaneously, signaling the reset process has begun.

After rebooting, the device will return to factory settings. Now you need to connect your computer or laptop to any LAN port the router being configured using an Ethernet cable. Do not connect the cable from the primary router yet! The computer should obtain an IP address automatically from the secondary router. Open a browser and enter the web interface address, which is located on the sticker on the bottom of the device (often this is 192.168.0.1, 192.168.1.1 or a domain name like tplinklogin.net).

• 🔌 Connect the cable from your ISP or main router only after the secondary device is fully configured.
• 🔑 Write down the factory login and password if you plan to use them to access the access point interface in the future.
• 📶 Make sure that the Wi-Fi module on the router you are configuring is enabled by default after the reset.

Once you've logged into the control panel, you'll see the manufacturer's standard interface. If the device prompts a quick setup wizard, it's best to skip it or select "Manual" mode for full control. Our goal is to change the network settings so that the router stops acting as a router and becomes a transparent bridge.

⚠️ Attention: Router interfaces from different manufacturers (Asus, TP-Link, Keenetic, MikroTik) may differ significantly visually, but the setup logic remains the same. Look for sections labeled "LAN," "Network," or "Local Area Network."

Changing the IP address of a local network

The most important technical step in the setup process is changing the IP address of the secondary router's LAN interface. By default, most devices have an address 192.168.0.1 or 192.168.1.1If your main router that distributes the Internet has exactly the same address, a problem will arise. IP conflict, and the network will stop functioning correctly. Even if the addresses differ, for ease of administration, it's best to align them with a unified logic.

Find the section in the menu Network (Network) -> LAN (Local Network). Here you need to enter a new static address for the access point. Let's assume the main router has the address 192.168.1.1Then, for the access point, you should select an address from the same subnet, but outside the range of the main router's DHCP server. For example, 192.168.1.250 or 192.168.1.2This will allow you to always know where to open the access point settings in the future.

After changing the IP address and saving the settings, the router will reboot. Your computer will lose connection to it because it will try to access the old address. You will need to manually enter a static IP address from the same subnet (e.g., 192.168.1.50) or simply re-enter the interface using the new address you just set.

Changing the LAN address is the foundation upon which all subsequent operation of the access point is built. Without this step, the device will attempt to act as the default gateway for its clients, creating a double NAT, which will lead to problems with online games, torrents, and some messaging apps.

Disabling the DHCP server

The key feature that needs to be disabled on the secondary router is DHCP serverIn a normal network setup, there should only be one DHCP server—on the main router. It is responsible for assigning IP addresses to all connected devices. If DHCP is left enabled on the access point, a "server war" will ensue: devices will receive random addresses from one router after another, resulting in internet access failure.

In the same section LAN or in the adjacent menu DHCP Server Find the server status switch. Select the option Disable (Disable) or uncheck "Enable." After this, the router will stop issuing addresses and will function solely as a switch and wireless access point. All IP address requests will be forwarded via the cable to the main router.

After disabling DHCP, be sure to save the settings. The device may warn you that a reboot is required for the changes to take effect. Accept it. Now your router is theoretically ready to operate as an access point; all that remains is to configure the wireless network.

Setting up a wireless Wi-Fi network

Now let's move on to setting up the radio module. Go to the section Wireless (Wireless mode) Here it is important to set the network name (SSID). For the best roaming experience, it's recommended to set the network name (SSID) and password exactly the same as those on your main router. However, the broadcast channels should be different to avoid interference.

In the security settings, select the encryption type WPA2-PSK (or WPA3, if all devices support it) and set a strong password. In the "Channel" field, it's best to select a fixed value rather than "Auto." If the main router broadcasts on Channel 1, set the access point to Channel 6 or 11. This minimizes signal interference, especially in apartment buildings where the airwaves are clogged with neighboring networks.

Don't forget to set up a guest network if you need one, although this is less common in access point mode. After applying the settings, the Wi-Fi module will restart. Now, if you connect a cable from the main router to the LAN port of the configured device, the internet should appear on the wireless clients.

Why is it important to space channels?

If two routers operate on the same channel, they will "shout" at each other, reducing overall speed. In the 2.4 GHz standard, only channels 1, 6, and 11 are non-overlapping.

Physical connection and operation check

The final step is to properly physically connect the devices. Take an Ethernet cable. Plug one end into any available space. LAN port the main router (the one that distributes the Internet). Connect the other end to any LAN port configured access point. Important: The WAN (Internet) port on the second router is not used in this diagram and must remain free! Using the WAN port will start the routing process that we just disabled.

After connecting the cable, wait for the indicators to load. Typically, the LAN and Wi-Fi lights will light up. Use your smartphone or laptop, search for your network by name, and try connecting. If the device receives an IP address from the main router (you can check this in the connection properties) and has internet access, the setup was successful.

⚠️ Attention: Some modern routers (for example, Asus routers with AiMesh or Keenetic routers with "Access Point" mode in their firmware) may have a dedicated software mode switch. If the interface has a clear "Operating Mode: Access Point" option, enable it—it will automatically disable DHCP and reassign ports.

Check the connection speed at different points in the room. Ideally, the video call should be uninterrupted when moving from one router's coverage area to another, although in a simple setup (without Mesh), there may be a brief delay when the client switches between access points.

Signal placement and optimization

Proper access point placement is just as important as software settings. Don't hide the router in a closet, alcove, or behind a TV. Metal surfaces and mirrors block the signal, significantly reducing the range. The optimal location is in the center of the area where coverage is needed, 1.5–2 meters above the floor.

If you use a range 2.4 GHzKeep in mind its long range, but low speed and noise pollution. For 4K video streaming, it's better to set up an access point in the 5 GHz band, but its range will be shorter. A dual-band router, which distributes both types of signals simultaneously, is ideal.

• 📡 Place antennas vertically for horizontal signal propagation.
• 🔋 Avoid proximity to microwaves and baby monitors that create interference.
• 🏠 In larger homes, cascade access points, but try not to make the chain longer than 2-3 devices.

What to do if the access point does not distribute the Internet?

First, check the cable between the routers—it should be intact. Make sure DHCP is disabled on the second device. Check that the IP addresses match in the subnet (the first three digits of the address should be the same). Also, try temporarily disabling the MAC address filter on the main router.

Is it possible to connect routers via Wi-Fi without a cable?

Yes, this is called WDS or "Repeater" mode. However, in this case, the network speed will drop by at least half, since the radio channel will be transmitting and receiving data simultaneously. A cable connection (AP mode) is always more stable and faster.

Do I need to update the firmware on my old router?

Recommended. Updating the firmware can fix security issues and improve the stability of the Wi-Fi module. Download firmware only from the official website of your model's manufacturer.
