In dense urban areas or with a complex home layout, the standard coverage of a primary router is often insufficient to provide reliable signal reception in distant rooms. Instead of purchasing expensive mesh systems or complex repeaters, you can effectively utilize your existing equipment. Converting an old or additional router into an access point (wireless mode) Access Point) is a proven way to expand your coverage area without losing speed.
This configuration allows you to create a single wireless network where devices can switch between routers—though not as seamlessly as in mesh systems, it's stable and maintains high throughput. Unlike repeater mode (WDS), which often cuts speed in half, a wired connection between the main gateway and the access point ensures maximum performance. All you need is a patch cord and access to the device's web interface.
There are two main ways to accomplish this: using the built-in "Access Point" mode, if your router's firmware supports it, or manually reconfiguring the network settings. The first option is significantly simpler and requires minimal knowledge, while the second provides complete control over the process and is suitable for any equipment, even the most budget-friendly. In this article, we'll examine both methods, focusing on the nuances of IP addressing and security.
Before setting up, it's important to clearly understand the difference between a router and an access point. A router manages data flows between your local network and the internet, assigning IP addresses to devices. An access point simply broadcasts a Wi-Fi signal, acting as a bridge between the wired and wireless networks, without performing any routing. This is precisely the function we'll be emulating.
Equipment preparation and compatibility testing
The first step is choosing the right device for repurposing. Almost any modern router, whether TP-Link, Asus, D-Link or Keenetic, can be switched to access point mode. However, older models that only support the standard 802.11n or 802.11g, will become a bottleneck for high-speed internet, so their use only makes sense for smart home devices or older gadgets.
You will need a patch cord (Ethernet cable) long enough to connect the main router to the device being configured. During the initial setup phase, it's best to connect to your computer or laptop via cable to avoid connection interruptions while changing network settings. Connecting wirelessly during the setup process may result in loss of interface access.
⚠️ Attention: Before starting any manipulations with network settings, it is strongly recommended to perform a full reset of settings (Reset) on the router being configured. This ensures that no old routing rules or IP address conflicts remain in the configuration.
It's also worth finding out the IP address of your main router (gateway) in advance, as you'll need it for proper configuration. Typically, this address will look something like this: 192.168.0.1 or 192.168.1.1If you haven't changed the default settings, this information is often found on a sticker on the bottom of the device. It's important that the addresses of the primary and secondary routers are in the same subnet, but not the same.
Method 1: Using the built-in Access Point mode
Many modern manufacturers integrate a special operating mode into their firmware that automatically disables router and DHCP server functions, leaving only access point functionality. This is the simplest and safest method, eliminating the risk of rookie errors during manual configuration. First, check for this option in your device's interface.
To access the control panel, connect your computer to the router's LAN port and enter its IP address in your browser. The default login and password are also listed on the device's casing. After logging in, look for a section that may be called Opening hours, Operation Mode, Administration or System. In the menu Keenetic, for example, it is a separate component that needs to be activated.
Select a mode from the list Access point (Access Point). The system will warn you that the device's IP address may change and offer to automatically obtain the new settings from the main router. This is key: in this mode, your router will automatically request the IP address from the main device, eliminating the need to enter it manually.
- 📡 Automation: All necessary services except Wi-Fi broadcasting will be disabled automatically.
- 🔌 Connection: In this mode, the cable from the main router is most often connected to the WAN port (blue), but some models require connection to the LAN port.
- 🔄 Reboot: After applying the settings, the device will reboot and become accessible via the new IP address assigned by the main router.
After activating the mode and rebooting, connect the cable from the LAN port of the primary router to the corresponding port on the secondary device. Unless otherwise stated in the instructions, the WAN port is often used in access point mode, as the port logic is software-modified. Check the client list on the primary router—the new device should be detected as a client.
Method 2: Manual configuration by disabling DHCP
If your router model doesn't have a built-in mode switch, you'll have to configure it manually. This method is universal and works on 100% of devices. It essentially turns the router into a simple Wi-Fi switch by disabling its ability to assign IP addresses.
Start by connecting your computer to the secondary router (which will serve as the access point) via cable, without connecting it to the main network yet. Go to the web interface and find the section LAN or Local area networkYou need to change the IP address of the router itself. If the main router has an address 192.168.0.1, then set the secondary address 192.168.0.2 or any other free one in this range.
⚠️ Note: After changing your router's IP address, you will no longer be able to access its control panel using the old address. To continue configuring your router, you will need to enter the new IP address you just set in your browser.
The next critical step is to disable the DHCP server. Find the section DHCP Server or DHCP settings and select the option Disable (Disable). This action will prevent the router from distributing addresses to connecting devices; only the main router will perform this function. Without this step, a conflict will occur in the network, and the internet will not work.
Now set up your wireless network. In the section Wireless or Wi-Fi Set the network name (SSID) and password. You can name the network the same as your main network for seamless roaming (although switching devices will not be instantaneous), or give it a unique name, for example, Home_WiFi_ExtFor maximum compatibility, select mixed mode (802.11 b/g/n/ac).
The final step is the physical connection. Save all settings. Now take the cable coming from the main router's LAN port and plug it in. LAN port (yellow) of the secondary router. The WAN port (blue) remains free in this method! Traffic will now flow through the LAN ports, as the device functions as a switch.
☑️ Manual setup checklist
Setting up security and selecting a Wi-Fi channel
Once the technical part is completed, it's necessary to ensure the security and stability of the signal. Standard encryption settings are often outdated, so it's important to check the protocol used. In today's environment, the minimum acceptable standard is WPA2-PSK with encryption algorithm AES. Using obsolete TKIP or WEP makes your network vulnerable to hacking in minutes.
Pay special attention to your wireless network channel selection. In apartment buildings, the airwaves are clogged with signals from neighboring routers, causing interference and speed drops. In the 2.4 GHz band, it's best to use only channels 1, 6, or 11, as they don't overlap. For the 5 GHz band, channel selection is less critical due to the large number of available frequencies, but manually selecting the least congested channel can improve stability.
| Parameter | Recommended value | Description |
|---|---|---|
| Security mode | WPA2-PSK (AES) | Reliable traffic encryption |
| Channel (2.4 GHz) | 1, 6 or 11 | Non-overlapping frequencies |
| Channel width | 20 MHz (for 2.4 GHz) | Reduces interference in noisy environments |
| Signal strength | High / 100% | Maximum area coverage |
Don't forget to change the default password for accessing your router's control panel. The default logins and passwords (admin/admin) are publicly available, and anyone who connects to your Wi-Fi network can reconfigure the device or steal your data. Create a complex password using a combination of letters, numbers, and special characters.
Why is 20 MHz channel width better in 2.4 GHz band?
Although the 802.11n standard allows for the use of a 40 MHz bandwidth to double speed, in multi-apartment buildings this often leads to a catastrophic drop in connection quality due to overlapping channels. A narrow 20 MHz channel is more resistant to interference and provides a more stable, though not the fastest, ping.
Diagnostics and troubleshooting
Even with proper configuration, connection issues may still occur. The most common is a lack of internet access on devices connected to the access point, even though the Wi-Fi network is visible. This almost always indicates a problem with DHCP or the gateway. Make sure the client device (phone, laptop) is set to obtain an IP address automatically in its IP settings.
If devices receive IP addresses but cannot see each other on the local network (for example, a printer or media server is not working), check if the client isolation feature is enabled on the access point (AP IsolationThis feature is designed for guest networks and prevents data exchange between devices within the Wi-Fi network. It should be disabled for home use.
If the connection speed through the access point is significantly lower than directly from the main router, check the cable quality. For speeds above 100 Mbps, an 8-core cable is required (Cat 5e and higher). If 4 out of 8 wires are damaged or not connected, the speed will be automatically limited to 100 Mbps, even if the provider's tariff is higher.
⚠️ Note: Router firmware interfaces are constantly updated. Menu locations, item names, and procedure may vary depending on the firmware version. If you can't find the item described, search for a similar one or refer to the manufacturer's official documentation.
Comparison of operating modes: which one to choose?
The choice between repeater, access point, and mesh mode depends on your specific needs. The access point mode we've discussed offers a good balance of price, quality, and speed, but requires cabling. If cabling isn't feasible, you'll have to use repeater mode (WDS), sacrificing speed, or purchase a full-fledged mesh system.
The access point is ideal for transmitting a signal through walls where cables are already installed (for example, in another room or on the same floor). It provides a stable connection that doesn't rely on the wireless signal from the main router, which is critical for video calling, online gaming, and 4K video viewing.
Using an old router as an access point is an eco-friendly and cost-effective way to upgrade your network. Not only do you expand your coverage, but you also give your equipment a second life, preventing it from ending up in the trash. Proper setup allows you to create a powerful hybrid network that covers even complex locations.
Is it possible to connect routers via Wi-Fi without a cable?
Yes, this is called bridge mode (WDS) or repeater mode. However, in this case, the Wi-Fi speed on the second router will drop at least 50%, since the radio module cannot simultaneously receive and transmit data on the same frequency. A cable connection (access point method) is always preferable.
Questions and Answers (FAQ)
Do I need to connect a cable to the WAN port when setting up an access point?
In built-in Access Point mode, yes, usually; the manufacturer reassigns the ports themselves. With manual setup (method 2), the cable from the main router is connected strictly to LAN secondary port, and the WAN remains free.
Is it possible to keep the same Wi-Fi name on both routers?
Yes, you can. This will create the illusion of a unified network. However, devices will not switch between routers instantly, but only when the signal from the first one is completely lost. For truly seamless roaming, 802.11r/k/v protocols or mesh systems are required.
What should I do if I lose access to the second router's interface after setup?
During manual setup, you changed its IP address. Try entering the new address you set (for example, 192.168.0.2) into your browser. If you don't remember it, press the Reset button and start setup again, recording all changes.
Will IPTV work through such an access point?
Yes, if you use a wired connection between routers (LAN-to-LAN) and have disabled DHCP on the second device, IPTV multicast traffic will work correctly, since the devices are on the same local subnet.
