How to turn a router into a WiFi hotspot: a step-by-step guide

Many users are familiar with the situation when the WiFi signal becomes barely detectable in one room of the house or a remote office. Often, an old, but perfectly functional router sits collecting dust on a shelf, even though it could dramatically improve wireless network coverage. Turning a second router into access point (Access Point) is the most effective way to expand your coverage area without purchasing expensive Mesh systems.

Unlike repeater mode, which simply repeats the signal and often cuts the speed in half, a wired connection between the main and secondary devices provides a stable data transmission channel. LAN cableA cable running from the main router to the secondary router will serve as a backbone, transporting traffic at the maximum speed supported by your equipment. This solution is ideal for stationary devices such as Smart TV, game consoles or desktop computers.

Before setting up, it's important to understand the physical connection diagram. The primary device that distributes the internet remains unchanged, while the second router acts as a "translator" or bridge. The key difference between an access point and a router is the lack of a NAT function when distributing the Internet via cable.

Preparing equipment and resetting settings

The process should begin with preparing the hardware to avoid software conflicts. If you're using a previously used router, we strongly recommend performing a full factory reset. This ensures that old configurations saved by the provider or previous user don't interfere with the creation of the new network structure.

To reset, find the button on the device body. Reset or WPS/ResetDepending on the model, you need to hold it for 5 to 15 seconds while the power is on, until the indicators flash simultaneously. After rebooting, the device will return to factory settings, and you can connect to it via the default WiFi or LAN port.

• 🔌 Connect your computer to any LAN port (usually yellow) of the router being configured with a cable.
• 📱 Make sure your computer's network card is configured to obtain an IP address automatically (DHCP).
• 🔍 Look at the sticker on the bottom of the device: it contains the web interface address (for example, 192.168.0.1 or tplinklogin.net) and login details.

⚠️ Warning: If you do not perform a factory reset, IP address conflicts may occur on the network, which will cause the internet to stop working on all connected devices.

After successfully logging into the web interface, you will see the main control menu. Interfaces vary from manufacturer to manufacturer (TP-Link, ASUS, Keenetic, D-Link) may differ visually, but the operating logic remains the same. Your goal is to get to the local network settings section, which is often called LAN or "Local Area Network".

Changing the IP address of a local network

The first and most important step is to change the IP address of the router itself on the local network. By default, most devices have an address 192.168.0.1 or 192.168.1.1If your main router, which distributes the internet, has the same address, a conflict will occur, and you will not be able to manage any of the devices.

You need to change the last digit of the address to something unique, but keep it in the same subnet as the main device. For example, if the main router has the address 192.168.1.1, then the second router being configured needs to be assigned an address 192.168.1.2 or 192.168.1.254This will allow you to always know the address of the access point's control panel in the future.

In the settings menu, find the field IP Address or "LAN Address." Enter the new address, ensuring the first three digits match the main router's address. After applying the settings, the device may reboot, and to access its settings further, you'll need to enter the new address in your browser.

• 📍 Find the IP address of the main router (default gateway) via the command line ipconfig.
• ✏️ Give the second router an address from the same subnet, but with a unique last octet (for example, .2).
• 💾 Save the settings and reboot the device if necessary.

What to do if you forgot your new IP address?

If you've changed your router's IP address and forgotten it, the only way to regain access is to reset it again using the Reset button. Afterward, the device will revert to the factory address indicated on the sticker, and you'll have to repeat the IP change procedure.

Checking accessibility is an important step. After changing the address, try pinging the new IP or opening it in a browser. If the admin panel page opens, you've successfully resolved the addressing issue and are ready for the next step.

Disabling the DHCP server

This is a critical step, without which the network will not function. There can only be one active router in any local network. DHCP server, which assigns IP addresses to connected devices. This function should only be performed by the main router receiving internet from the ISP.

If DHCP is left enabled on the second router (which we're converting into an access point), it will begin issuing its own addresses, causing chaos on the network. Computers and phones will receive incorrect gateway and DNS settings, causing internet connection failure or instability.

Find the section in the menu DHCP or "LAN Settings". There will be an option there. DHCP Server. Switch it to position Disable (Disable) or OffAfter this, the router will stop distributing addresses and will simply transmit traffic, acting as a switch with a wireless module.

⚠️ Important: After disabling the DHCP server, you may lose access to your router settings wirelessly if your computer doesn't have a static IP address. For further configuration, connect via cable or manually enter a static address.

The table below shows an example of the correct settings for two routers on the same network:

Once you've ensured DHCP is disabled, you can proceed to setting up wireless broadcasting. This step will transform the device into a fully functional WiFi access point.

Setting up a wireless WiFi network

Now you need to configure the wireless signal settings. In the menu, select the section Wireless or "Wireless Mode." Here you set the network name (SSID) and password. You can name the network the same as on the main router to create a unified space, or give it a unique name to identify which access point you're connected to.

For maximum compatibility and security, it is recommended to use the encryption standard WPA2-PSK or WPA3, if the devices support it. Protection type WEP It is long outdated and easily hacked, so its use is unacceptable in modern conditions.

The broadcast channel is an important parameter. If you're creating a single network with the same name on two routers, the channels should be different to prevent interference. For the 2.4 GHz standard, channels 1, 6, and 11 are optimal, as they don't overlap.

• 📡 Set the network name (SSID) - you can use a prefix, for example, Home_Ext.
• 🔐 Set a strong password using mixed case and numbers.
• 📶 Select a fixed channel (1, 6 or 11) to avoid interference from neighboring networks.

After setting up WiFi, be sure to save the changes. The router may reboot. Now, if you connect the cable from the main router correctly, the wireless network should work.

Physical connection via cable

The final step is to properly connect the devices with wires. A common mistake here is to plug the cable into the port. WAN (Internet) on the second router. In access point mode (when DHCP is disabled), the cable must be inserted into LAN port.

Take a patch cord (network cable). Connect one end to any free LAN-port on the main router. Connect the other end to any LAN-port (usually numbered 1-4) on the router being configured. The WAN/Internet port on the second device remains empty.

After connecting the cable, the LAN indicators on both devices should light or blink, indicating physical contact. If the indicators don't respond, check the cable for integrity and the tightness of the connectors.

⚠️ Note: Some modern routers (such as Keenetic or new TP-Link models) feature auto-MDI/IX port detection. In these models, the cable can be connected to both the WAN and LAN ports, and the system will automatically detect that it should operate in access point mode. However, the classic setup requires a LAN connection.

Test the network by connecting your smartphone or laptop to the access point you created. If the internet works, the configuration is correct.

Alternative mode: Access Point Mode (AP Mode)

There is a simpler method available on many modern router models. Manufacturers often implement software Access point mode (Access Point Mode), which automatically performs all the actions described above: changes IP, disables DHCP and reconfigures ports.

You can find this function in the section Opening hours, Operation Mode or in quick settings (Quick Setup). After selecting the "Access Point" option, the router will prompt you to reboot and apply the necessary changes. In this case, the cable can often be connected to the WAN port, as the device's operating logic is modified by software.

Using the built-in mode is convenient because the control interface remains clear, and the risk of making mistakes in manual settings is minimal. However, on older models (for example, early versions of the D-Link DIR-300) such a function may not exist, and then manual configuration by disabling DHCP is the only way out.

• 🚀 Find the "Operating Mode" section in the router menu.
• ⚙️ Select an option Access Point or "Access Point".
• 💾 Save the settings and wait for the device to reboot.

If your router supports this mode, it will save time and simplify the process of resetting to factory settings in the future, if necessary.

What is the difference between AP mode and Bridge mode?

Access Point (AP) mode creates a new WiFi network (or extends an existing one) with full functionality. Bridge/WDS mode is often used to wirelessly connect two routers without a cable, but can reduce speed and requires support from both devices.

Diagnostics and problem solving

Even with the correct settings, problems may arise. If the internet doesn't appear, first check whether the device is receiving an IP address. If the address begins with 169.254.x.x, this means that DHCP is not working or the cable is not connected correctly.

A common problem is frequency band incompatibility. If the main router only broadcasts 5 GHz, and the second (older) router only broadcasts 2.4 GHz, they won't be able to operate in a single seamless network with the same name without special roaming protocols. In this case, it's best to give the networks different names so devices can switch between them manually.

It is also worth making sure that filtering is not enabled on the main router. MAC addressesIf new devices are blocked from connecting, the second router will not be able to access the network. Add the second device's MAC address to the allowed list on the main router.

Why doesn't the second router distribute internet after setup?

The problem is most likely with the IP addresses. Make sure the second router's IP address is in the same subnet as the first (the first three digits match), but not exactly the same. Also, check that the gateway on the connecting devices points to the main router's address, not the access point.

Is it possible to connect routers via WiFi without a cable?

Yes, this is called WDS mode or "Wireless Bridge." However, speed in this mode drops by at least half, and stability depends on distance and interference. For fixed access points, a cable connection (twisted pair) is always preferable.

Do I need to reset my WiFi password?

Yes, security settings on the second router are configured independently. For user convenience, it's recommended to set the same password (and network name, if you're not using mesh), but they may technically differ if you're creating a guest area.

Will this scheme work for routers from different manufacturers?

Yes, access point mode is standard. You can connect an ASUS router to a TP-Link or D-Link router. The main thing is to configure IP addressing correctly and disable DHCP on the secondary device.
