Using a second router as a access points — is the most effective way to extend the coverage area of a wireless network without sacrificing the speed typical of conventional repeaters. When you connect a device TP-Link By connecting the router to the main router via cable, you create a unified infrastructure where all devices are on the same local network and can see each other. This is an ideal solution for large apartments, offices, or cottages where the main router's signal simply doesn't reach distant rooms.
Unlike repeater mode, which cuts the channel speed in half, access point mode (Access Point) allows you to transfer data at the maximum speed available with your provider's plan. The process of switching operating modes on devices TP-Link has become much simpler in the latest firmware versions, but requires attention to the details of IP addressing settings. It is critical to change the secondary router's IP address before connecting it to the primary network to avoid address conflicts and loss of access to the management interface.
Before you begin changing settings, you need to physically prepare your equipment. You'll need a computer or laptop, a network cable (patch cord), and the router itself. TP-Link, which will act as a hotspot. Make sure the primary internet connection is already configured and working properly on the main device, as we'll be configuring an extension to this existing network.
Preparing equipment and resetting settings
Any reconfiguration of network equipment should always begin with reset settings to factory defaults. This ensures that the configuration doesn't contain any old rules that could conflict with the device's new role. On the back panel of the routers TP-Link there is usually a button Reset or WPS/Reset, which must be held for about 10 seconds with the power on until the indicators blink simultaneously.
After rebooting, connect your computer to any LAN port The router being configured using a cable. Don't connect the device to the ISP's main network or the main router yet. Open your browser and enter the standard address in the address bar, which most often looks like 192.168.0.1 or 192.168.1.1The default login details are located on the sticker on the bottom of the case.
⚠️ Warning: If you don't reset your settings, your old Wi-Fi password or previously changed IP address may block your access to the settings, and you'll have to start the process over again.
On some newer models with cloud management, logging into the interface may require creating an account. TP-Link IDFor local setup, it's best to select the sign-in option without registration or use the "Access Point" mode immediately upon first launching the Quick Setup Wizard, if it offers this option.
Changing the router's IP address
The most important step is to change the secondary router's IP address so that it doesn't match the primary gateway's address. If your primary router hands out addresses in the range 192.168.0.x, then the second device needs to be assigned a static address from the same subnet, but outside the DHCP range of the main router. For example, if the main router has the address 192.168.0.1, ask the second one 192.168.0.250.
To perform this operation, go to the menu Network (Network) → LAN (Local Area Network). In the field IP Address Enter a new address. Make sure that Subnet Mask (Subnet mask) is set to 255.255.255.0After saving the settings, the router will reboot, and you will need to re-login to the web interface using the new IP address.
Why is this necessary? If both routers remain with the address 192.168.0.1, an IP conflict will arise, and the network will stop functioning correctly. Computers won't understand which device to send requests to, leading to constant connection interruptions.
Setting up a wireless WiFi network
Now you need to configure the wireless broadcasting settings. Go to the section Wireless (Wireless mode) Here you should set SSID (network name) and password. You can name the network the same as the main one so that devices switch automatically, or give it a unique name, for example, TP-Link_Extension, so you can clearly understand which point you are connected to.
In the section Wireless Security select the type of protection WPA2-PSK or WPA3If your devices support the new standard, create a strong password containing letters and numbers. It's important to select the correct region in the settings to ensure the signal strength complies with legal requirements and doesn't cause interference.
- 📡 Channel Width: For the 2.4 GHz range, it is better to choose 20 MHz for stability or Auto if there are few networks on the air.
- 🔒 Encryption: Always use AES, avoiding the outdated TKIP which reduces speed.
- 📶 Transmit Power: Set to High if the router is far away, or Medium if it is in the next room.
Don't forget to save the settings. Afterward, the router may prompt you to reboot. Make sure your laptop is connected to the new Wi-Fi network and is checking for internet access, although full access may not yet be possible due to DHCP being enabled.
Disabling the DHCP server
The key to turning a router into an access point is disabling the service DHCPIn access point mode, only the main router should distribute IP addresses. Leaving DHCP enabled on the secondary device will result in chaos: clients will receive incorrect gateway addresses and will be unable to access the internet.
Find the section in the menu DHCP → DHCP Settings. Select an option Disable (Disable) or uncheck the "Enable DHCP Server" option. Click the button SaveAfter this, the router will stop issuing addresses and will simply begin forwarding client requests to the main router.
☑️ Check before connection
After disabling DHCP, the connection to the computer may be lost because the old IP address will no longer be valid. You may need to re-obtain the address automatically or assign a static IP address to the computer's network card in the same subnet to access the settings again.
Physical connection and operation check
Now it's time to connect the devices with a cable. Take a patch cord and plug one end into LAN port the main router (which distributes the Internet), and the other end is in LAN port secondary router TP-Link. Important: port WAN (Internet) on the secondary router in this scheme is usually not used and should remain free, unless the model does not have a special mode switch.
⚠️ Note: On some modern TP-Link models with the "Repeater/AP Mode" feature, the WAN port can function as a LAN port. Check the manual for your specific model to avoid confusion about the ports.
After connecting the cable, the LAN indicators on both devices should light up or blink. Try connecting to the created Wi-Fi network from your phone or laptop. If everything is set up correctly, the device will receive an IP address from the main router and immediately gain internet access.
Check your connection speed using speed testing services. It should be comparable to a wired connection. If the speed is low, check the cable quality—for gigabit speeds, you need an 8-wire cable of at least category 1. Cat5e.
Comparison of router operating modes
Understanding the differences between operating modes helps you choose the right strategy for your situation. Router, access point, and repeater modes each have their own characteristics that affect network stability and speed. Below is a table to help you make your choice.
| Parameter | Router Mode | Access point (AP) | Repeater Mode |
|---|---|---|---|
| Connection | Provider cable in WAN | LAN cable from the main router | Wireless (via Wi-Fi) |
| IP Distribution (DHCP) | Included | Disabled | Disabled (usually) |
| Speed | 100% (depending on the tariff) | 100% (depending on cable) | Up to 50% (channel loss) |
| Network isolation | Different subnets | Unified network | Unified network |
As the table shows, a wired access point outperforms a wireless extender in terms of stability and speed. Using a cable ensures you don't lose half your channel's bandwidth, which often happens with cheap extenders.
Common problems and their solutions
Despite the simplicity of setup, users often encounter common errors. One of the most common is a lack of internet connection when connecting to an access point, even though the Wi-Fi network is visible and the password is accepted. This usually means DHCP hasn't been disabled or the cable is plugged into the WAN port instead of the LAN port.
Another problem is low data transfer speed. This can be caused by using an old cable (4 wires instead of 8), which limits speeds to 100 Mbps, or by interference in the airwaves. In such cases, changing the Wi-Fi channel to a less congested one can help.
What to do if you forgot your new IP address?
If you've changed your router's IP address and forgotten it, you'll need to reset it using the Reset button. Afterward, the device will revert to the factory address indicated on the sticker, and you'll need to repeat the IP configuration process.
If devices cannot see each other on the local network (for example, a printer is not accessible from a computer), check your firewall settings and make sure that the correct workgroup is selected on both routers (if they are on different subnets) or on the clients.
Additional customization options
Modern routers TP-Link offer many additional features that can be used even in hotspot mode. For example, you can set up a guest network so visitors don't have access to your personal files. This is done in the Guest Network.
Also worth paying attention to is the function Parental Control (Parental Control). Even when operating as an access point, the router can filter traffic according to a schedule or block unwanted websites if this feature is supported at the firmware level and does not require an active WAN connection to check the time.
- ⏱️ Time Control: Restrict network access for specific devices at specified times.
- 🚫 Access Control: Complete ban or allow access only for known MAC addresses.
- 📊 Traffic Statistics: Monitoring the amount of data transferred through the access point.
Don't forget to update your device's firmware periodically. Manufacturers release updates that fix security vulnerabilities and improve the stability of the wireless module. You can check for updates in the section System Tools → Firmware Upgrade.
Can I use the WAN port on the secondary router?
In the classic "Access Point" setup, the WAN port is not used; the cable is connected to the LAN. However, if the router has a special "Access Point" mode (a switch on the router case or in the menu), the system will automatically redirect the traffic, and then any port, including the WAN, can be used as a regular LAN.
Why did the internet disappear on all devices after setup?
Most likely, an IP address conflict arose because you didn't change the secondary router's address, and it now matches the primary router's address. Or, you forgot to disable the DHCP server on the secondary device, and now the two servers are interfering with each other's address distribution.
Will IPTV work through such an access point?
Yes, it will. Since the access point simply extends the local network via cable, all multicast streams and IPTV services are transmitted transparently. The main thing is that the cable between the routers is of high quality and supports the required speed.
How do I return to my access point settings if it's located far away?
You'll need to know the IP address you assigned to your access point. Enter it in a browser from any device connected to the network. If you've forgotten the address, you'll have to physically go to the router and reset it using the Reset button.
