Often, a situation arises in a home or office where the main router isn't sufficient to cover all rooms with a high-quality signal, but installing new cables or purchasing specialized equipment isn't feasible. In such cases, the old or additional router TP-Link It can be converted into a full-fledged access point, expanding network coverage without sacrificing speed. This solution allows you to create a unified wireless network where devices will automatically switch between signal sources if they are on the same subnet.
Turning a router into an access point is the process of reconfiguring its network interfaces so that it no longer serves as an IP address dispenser (DHCP) and becomes a simple bridge between a wired and wireless connection. The key point The key here is to properly connect ports and disable services that may conflict with the main router. Unlike repeater mode, which receives the signal over the air and transmits it further, an access point requires a cable connection, which guarantees maximum stability and data transfer speed.
This instruction covers all stages of preparation and configuration of the interface for modern and classic models. TP-Link Archer And TL-WRWe'll cover not only the standard steps but also the nuances users encounter when IP address conflicts or problems accessing the web interface. Proper implementation of this plan will allow you to fully utilize your existing equipment, avoiding unnecessary expenses on new gadgets.
Equipment preparation and compatibility testing
Before changing settings, you need to physically prepare your workspace and ensure that your equipment supports the required functionality. Almost all modern routers TP-Link, even budget models of the series TL-WR740N or TL-WR841N, have a built-in "Access Point" mode. However, in older firmware versions, this mode may be hidden or require manual disabling of the DHCP server.
You will need a computer or laptop with a network port, the main router (which already distributes the Internet) and the router itself. TP-Link, which will be reconfigured. Also, don't forget an Ethernet cable for the initial connection. It's important to understand that during the setup process, you will lose internet access on the device being configured, as its IP address will change.
Make sure you know the IP address of your primary router, as it will become the default gateway for the new access point. If you plan to use the device in a damp or dusty area, check the condition of the ventilation holes, as the device may operate 24/7 in access point mode.
⚠️ Attention: If your TP-Link If you previously used your router as your primary PPPoE or L2TP connection, be sure to perform a factory reset to avoid connection profile conflicts.
Changing your IP address to avoid conflicts
The first and most important step is to change the LAN IP address of the router you're configuring. By default, most devices TP-Link use the address 192.168.0.1 or 192.168.1.1If your main router has the same address, a conflict will occur and the network will stop working properly.
Connect your computer directly to TP-Link cable to any LAN port (yellow). Log in to the web interface by entering the standard address in your browser. Go to the menu Network → LAN (Network → Local Network). Here you need to change the third or fourth octet of the address. For example, if the main router has the address 192.168.0.1, set the address of the second device 192.168.0.250.
After saving the settings, the router will reboot, and you'll need to log in to the interface again using the new IP address. This is a critical step, as this address will be used for further management of the access point after it's integrated into the network.
- 🔹 Make sure the new IP address is in the same subnet as the main router (the first three numbers should match).
- 🔹 Write down the new address on a sticker attached to the device body so you don't forget it in the future.
- 🔹 Leave the subnet mask as default
255.255.255.0, unless you are an advanced network administrator.
Disabling the DHCP server
In access point mode TP-Link The router should not distribute IP addresses to connected devices. Only the primary router performs this function. Leaving DHCP enabled on both devices will result in clients receiving incorrect gateway and DNS settings, resulting in internet inaccessibility.
While in the web interface (already on the new IP), go to the section DHCP → DHCP Settings. Select an option Disable (Disable) and click the save button. After this, the router will stop issuing addresses and will function exclusively as a switch with wireless data transfer.
Some models TP-Link With the new firmware (blue interface), the routers have an automatic mode. In this case, selecting "Access Point" in the "Operation Mode" menu automatically disables DHCP. However, manually checking this setting is always a good idea.
☑️ Checking DHCP settings
It's worth noting that after disabling DHCP and rebooting, if you connect a computer to this router, it may not automatically obtain an IP address if there is no other DHCP server on the network. This is normal behavior for a configured access point.
Setting up a wireless WiFi network
Now you need to configure the wireless settings. To create a unified space (seamless roaming in its simplest form), we recommend setting the network name (SSID) and password to match those used on your main router. However, if you want to clearly separate coverage areas, you can use a unique name.
Go to the section Wireless → Wireless Settings. Here you can set the network name (SSID). In the field Region (Region) Select your country or "United States" for maximum signal strength (although this may interfere with local regulations, it technically increases signal strength). It's best to leave the Channel setting at "Auto" so the router selects the least congested frequency.
Tab Wireless Security is responsible for protection. Select the encryption type. WPA2-PSK (or WPA3, if supported by clients), as this is the most secure standard. The password should be complex and contain letters and numbers. Avoid using special characters if you have older devices that may not correctly process certain characters in the password.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID (Network Name) | Home_WiFi (same as on the main page) | The name visible when searching for networks |
| Mode | 11bgn mixed | Compatibility with all devices |
| Channel Width | 20 MHz (for 2.4 GHz) | Less interference in apartment buildings |
| Security | WPA2-PSK (AES) | Data encryption standard |
Should I enable WPS?
The WPS function allows you to connect to WiFi without entering a password by pressing a button on the router. However, for security reasons, it's best to disable it (Disable), as it's vulnerable to brute-force attacks.
Physical connection and wiring diagram
After software configuration, you need to properly connect the devices with cables. Many users make the mistake of connecting the cable to the WAN port (blue), which is incorrect for access point mode (unless using a special router mode). The cable from the main router (from the LAN port) should go to LAN port (yellow) devices TP-Link.
The diagram looks like this: The ISP's internet cable enters the WAN port of the main router. A cable extends from any LAN port of the main router and runs into the room where the access point will be located. This cable is inserted into any of the yellow LAN ports. TP-Link. WAN port (blue) on TP-Link remains free.
If your TP-Link Supports software-based switching of operating modes (via the "Operation Mode" menu). Select "Access Point" there. In this case, the system will automatically reassign ports, and you can even use the WAN port as an additional LAN port. However, the classic LAN-to-LAN configuration works on all models without exception.
⚠️ Caution: When connecting the cable, make sure the connectors are securely locked. Poor contact can cause speeds to drop to 10 Mbps instead of 100 or 1000 Mbps.
Performance testing and diagnostics
Once the cables are connected, the router's lights should light up accordingly. Typically, the power light, wireless light, and the lights for the LAN ports to which devices are connected will be lit. If the LAN light isn't lit, check the cable or port on the main router.
To check, take your smartphone or laptop and connect to the new WiFi network. Try opening several websites. If the pages load, it means the main router's DHCP has assigned the correct IP address, and the internet is working. You can also check the device's IP address—it should be assigned by the main router, not the one assigned by the other router. TP-Link.
If you have any problems, try pinging the gateway. Open the command prompt (cmd) and enter ping 192.168.0.1 (or the address of your main router). If packets are being lost, there may be a network loop or an IP address conflict that was missed in the first step.
- 🔹 Check if your antivirus or firewall is blocking your local network.
- 🔹 Make sure your main router doesn't have MAC address filtering enabled, which could block new devices.
- 🔹 Reboot both routers sequentially: first the main one, then the access point.
Why is the speed lower than expected?
If you're using an older cable (Cat5 without the "e" prefix), it may limit speeds to 100 Mbps. For gigabit speeds, you need a Cat5e or Cat6 cable, which has 8 active conductors.
Frequently Asked Questions (FAQ)
Can you use TP-Link as an access point without a cable?
Technically, the "Access Point" mode requires a wired connection. If you want to transmit internet without a cable, you need the "Repeater" or "Range Extender" mode. Not all models TP-Link support repeater mode, as opposed to access point mode, which is available everywhere.
What should I do if I forgot the new IP address of the access point?
If you've changed your IP address and forgotten it, the only way to regain access is to perform a factory reset. To do this, press and hold the button Reset on the device body for about 10 seconds until the indicators flash. After this, the router will return to the address indicated on the sticker on the bottom.
Will the guest network work through the access point?
In simple AP (LAN-to-LAN) mode, client isolation and guest networks configured on TP-LinkGuest networks often don't work or work incorrectly, as the main router takes over client management. It's best to set up a guest network on the main device.
Will the internet speed decrease with this scheme?
With a wired connection to the access point, speed loss is virtually nonexistent, with the exception of minimal switching latency. This is much more effective than using repeaters, which cut the WiFi channel speed in half. The key is to use high-quality cable.
Is it possible to connect two TP-Link routers via WiFi in access point mode?
No, a traditional access point requires a cable. An over-the-air connection between two TP-Link routers is called a WDS Bridge or Repeater. These are different technologies. WDS requires support from both devices and is often less stable than a wired access point.
