The problem of "dead zones" in a wireless network is familiar to many owners of private homes and spacious apartments with thick walls. The signal from the main router may simply not reach distant rooms, leading to constant connection drops and low internet speeds. In such situations, the ideal solution is to use an additional device capable of receiving and amplifying the existing signal.
Model TP-Link TL-WR720N Originally designed as a portable router, its functionality allows this compact gadget to be transformed into a powerful amplifier. This is especially relevant for those who already own a router and don't want to buy new, expensive equipment. Converting a router into a repeater is a cost-effective way to improve connection quality without installing new cables.
In this article, we will examine in detail the process of flashing and setting up repeater modeYou'll learn the intricacies of working with firmware, choosing the right installation location, and troubleshooting common connection issues. Proper configuration will allow you to enjoy stable internet anywhere in the room.
Equipment preparation and compatibility testing
Before you begin setting up, you need to make sure your device is technically capable of operating as an amplifier. Not all versions TL-WR720N have a built-in "Range Extender" function in the factory firmware. These are usually models with a hardware version V3 or V4, which can be switched through the menu, or older versions that require the installation of alternative firmware.
You'll need a computer or laptop with a network adapter, a patch cord (Ethernet cable), and access to the main router's web interface to obtain the Wi-Fi password. It's also important to check the device's current firmware version to determine whether a firmware update is necessary. If there's no "Repeater" option in the menu, it means you can't expand your network using standard tools.
Make sure that the main router is working stably and distributing a Wi-Fi signal. Distance The distance between the main internet source and the future repeater shouldn't be too large, otherwise there won't be anything to amplify. Ideally, place the device halfway between the router and the poor reception area.
β οΈ Important: Before making any changes to the firmware, be sure to back up your current settings. In the event of a failure, you can restore the device's functionality by restoring the saved configuration file.
Firmware for the device to support repeater mode
If in the standard interface System Tools β Firmware Upgrade There's no option to change the operating mode; downloading specialized firmware is required. The manufacturer's official website may not provide such versions for older models, so enthusiasts often use modified files that add functionality. Universal Repeater.
The firmware update process is a critical step. A power outage or loss of connection to the web interface while data is being written can brick the router. Before starting, ensure the power supply is stable and the cable connection is secure.
What to do if the firmware does not install?
If the device is unresponsive after the update, try the TFTP recovery method. To do this, assign a static IP address of 192.168.0.66 to your computer, start the TFTP server with the firmware file, and, while holding the Reset button, turn on the router. The router will automatically download the file from your computer.
After downloading the firmware file (usually has the extension .bin) Go to the update menu. Select the file and click the "Upgrade" button. The process will take a few minutes, after which the device will reboot. If everything is successful, a new menu item for selecting the operating mode will appear in the interface.
Step-by-step instructions for setting up WAN/LAN
After successfully installing the software with repeater support, you need to properly configure the network interfaces. Access the web interface at 192.168.0.1 (or another one indicated on the sticker). Go to the section Network Mode or similar, where a choice of connection type is offered.
Select mode Repeater or Range ExtenderIn this mode, the WAN port on the device stops functioning as an input for the Internet from the provider and becomes part of the local network. All devices connected to TL-WR720N, will receive IP addresses from the main router.
- π‘ Select the "Repeater" operating mode in the Quick Setup menu.
- π Click the "Survey" button to search for available wireless networks.
- π Enter the password for your primary Wi-Fi network in the appropriate field.
- πΎ Save the settings and wait for the module to reboot.
It's important to change the IP address of the repeater itself so that it doesn't conflict with the main router. If the main router distributes addresses starting with 192.168.0.1, then it is better to set a static address for the repeater, for example, 192.168.0.250This will allow you to always have access to its settings, knowing the exact address.
Wireless Network Configuration and MAC Cloning
For seamless roaming (seamless transition between access points), it is recommended to configure the network name (SSID) and password identical to the main router. However, the broadcast channels should be different to avoid interference. For example, if the main router operates on channel 1, the repeater should be assigned channel 6 or 11.
Some providers provide internet access binding MAC address devices. If your provider uses this type of protection, you need to clone the MAC address of the computer on which the internet was originally configured, or the address of the main router. This is done in the section Network β MAC Clone.
| Parameter | Main router | TL-WR720N Repeater |
|---|---|---|
| IP address | 192.168.0.1 | 192.168.0.250 |
| SSID (Network Name) | MyHomeWiFi | MyHomeWiFi (or MyHomeWiFi_Ext) |
| Channel | 1 | 6 |
| Security | WPA2-PSK | WPA2-PSK |
After applying the settings, the wireless indicator on the case TL-WR720N The indicator should light up or start flashing, indicating a successful connection to the base station. If the indicator is red or not lit at all, check that the password you entered is correct.
βοΈ Checking Wi-Fi settings
Device placement and signal testing
The physical location of the repeater plays a key role in the effectiveness of the entire system. It is not recommended to install TP-Link TL-WR720N In an area where the signal has completely disappeared. The device must be located within range of the main router to be able to rebroadcast a strong signal further.
The ideal location is midway between the internet source and the problem room. Avoid placing the device near microwaves, baby monitors, and thick metal structures that shield radio waves. Height is also important: the higher the location, the better the signal propagation.
β οΈ Note: Firmware interfaces may vary depending on the hardware version. If you don't see the described items, check the exact model name and revision on the label on the bottom of the case.
To test the connection quality, use utilities on your smartphone or laptop, such as Wi-Fi AnalyzerWalk around your apartment and check the signal strength (RSSI) at different points. Within the repeater's coverage area, the signal strength should be stable, and the download speed should match your provider's plan.
Solving typical problems and diagnostics
During operation, situations may arise where devices don't see the repeater network or the connection speed remains low. Often, this is caused by device overheating or a software failure. In such cases, a full reset via the button helps. Reset on the back panel (hold for 10 seconds).
If the speed through the repeater is significantly lower than with a direct connection, try changing the wireless network channel to a less crowded one. Neighbors' routers can create significant interference, especially in apartment buildings. Using channels 1, 6, and 11 usually produces the best results.
It's also worth checking whether MAC address filtering is enabled on your main router. If so, you'll need to add the MAC address. TL-WR720N Add it to the list of allowed devices in the main router's settings. Without this, the repeater won't be able to access the network.
Why doesn't the repeater connect to the main router?
The most common cause is an incorrect Wi-Fi password or a mismatched encryption type. Ensure that the WPA2-PSK (AES) security type is selected on both devices. Also, check if there's a limit on the number of connected clients on the primary router.
Is it possible to connect two TP-Link TL-WR720N over the air?
Yes, this is possible, but it requires a complex setup. One device is configured as an access point, and the other as a client or universal repeater. However, for stable operation, it's best to use a wired connection or WDS mode if the firmware supports bridging between two TP-Link devices.
Will my internet speed decrease when using a repeater?
Yes, in wireless repeater mode, speed typically drops by approximately 40-50%. This is due to the device spending time receiving and then transmitting each data packet. For mission-critical applications, it's better to use a wired connection or mesh systems.
