In a modern apartment or office, where the walls may be made of reinforced concrete and the number of connected devices may number in the dozens, even the most powerful router can't always provide a stable signal in every corner of the room. It often happens that the internet is "flying" in one room, but the connection drops or the speed drops to critical levels in another. In such cases, purchasing new expensive equipment isn't always justified, especially if you have an old but functional router lying around, such as a popular model. TP-Link TL-WR740N.
Transforming this device into signal repeater (repeater) is an excellent solution for expanding your coverage area without breaking the bank. While the "Repeater Mode" feature may be missing or malfunctioning in the factory firmware of some versions of this model, there is a proven method for setting it up via the mode. WDS BridgingThis approach allows you to combine two wireless networks into one, providing seamless roaming for your devices. Let's take a closer look at how to implement this scheme.
Equipment preparation and diagnostics of the main network
Before you start setting up TL-WR740N To use a repeater, you need to prepare the primary router, which is already distributing the internet. You'll need to know the exact parameters of your current network, as the second router will work in conjunction with it. Ignoring this step will result in the devices not being able to "see" each other or an IP address conflict.
Connect to the main router from a computer or smartphone and access its web interface. This is usually done through a browser at 192.168.0.1 or 192.168.1.1You need to set three critical parameters: the wireless network channel, encryption type, and password. For stable operation of the WDS connection, the channel must be static, not automatic.
Please write down the following information, you will need it during the setup process:
- 📡 Channel: for example 1, 6 or 11 (must be fixed).
- 🔒 Protection type: usually WPA2-PSK.
- 🔑 WiFi password: your main network security key.
Also make sure that the function is enabled on the main router DHCP servers, as it will distribute IP addresses to all devices on the network, while our future repeater will only transmit data packets. If you change the channel on the main router, be sure to save the settings before moving on to the next step.
⚠️ Attention: Firmware interfaces may vary depending on the router's hardware version (V1-V6). If you don't find an exact menu match, search for similar items, as the WDS protocol logic is the same for all devices.📊 What's your current WiFi situation?The signal is everywhereThere are dead zonesThere is only one router and it is old.I use a mesh systemChanging the IP Address and Preparing the TL-WR740N
After you have fixed the parameters of the main network, we proceed to setting up the network itself. TP-Link TL-WR740NFirst, you need to reset it to factory settings to avoid configuration conflicts. To do this, turn on the device, find the button
Reset(often combined with the WPS button) and hold it for about 10 seconds until the indicators flash simultaneously.Connect your computer to TL-WR740N via cable or WiFi (the default network name is indicated on the sticker below). Log in to the web interface at
192.168.0.1. Standard login and password are —adminThe first thing we'll do is change the router's IP address so it doesn't match the main router's address. If the main router has an address192.168.0.1, then our repeater needs to be set, for example,192.168.0.254.To do this, go to the menu
Network → LANIn the field IP Address Enter the new address. Make sure the first three digits (the subnet) match the main router's, but the last one is different. After applying the settings, the router will reboot, and you'll need to log in to the interface again using the new address.Next, disable the DHCP server on TL-WR740N. This is a critical step! In repeater mode, only the main router should be distributing addresses. Find the menu
DHCP → DHCP Settingsand select the option DisableSave the changes. The device is now ready to configure the wireless bridge.☑️ Check before setting up WDS

Now let's move on to the most important part: setting up a wireless connection between routers. In the menu
Wireless → Wireless SettingsSet the same channel as the one you set on your main router. Don't leave it set to "Auto," as this will make the connection unstable.Check the box next to the item Enable WDS BridgingAfter this, a button will open.
Survey(or "Search"). Click it, and the router will scan the air, displaying a list of available networks. Find your primary network in the list and clickConnectThe router will automatically set it up. BSSID (MAC address) of the primary access point.In the section Wireless Security (Wireless Security) you must select the same encryption type as on the main router (usually WPA2-PSK). In the field Password Enter the password for your primary WiFi network. If the passwords or encryption types don't match, the connection will fail.
Parameter Main router TL-WR740N (Repeater) IP address 192.168.0.1 192.168.0.254 DHCP Server Enabled Disabled Channel 6 (Example) 6 (Strictly the same) SSID (Network Name) Home_WiFi Home_WiFi (Recommended) After entering all the data, click SaveThe router may prompt you to reboot. After turning it on, check the connection status in the menu.
Run Status. If in the field WDS Status is writtenRunorSuccess, which means the bridge was successfully built.What to do if WDS status is not "Run"?
If the status doesn't change to "Run," check that you entered the primary network password correctly. Also, make sure MAC address filtering isn't enabled on the primary router. Changing to a clearer channel (1, 6, or 11) can sometimes help.
Setting up a wireless network and security
Although the bridge is already configured, for the convenience of users it is recommended to set up a name and password for the bridge itself. TL-WR740NYou can set the same network name (SSID) and password as your main router. This will create the illusion of a single network, and devices will switch between routers automatically, although this may not always be perfect (depending on the client).
Go to
Wireless → Wireless Security. Set the option WPA/WPA2 - Personal (Recommended)In the field Wireless Password Set a password. Important: This password will now be used to connect to both routers if you selected the same network names.Don't neglect security. Using an open network or outdated WEP encryption makes your data vulnerable. WPA2-PSK with AES encryption is the optimal choice for home use, providing a balance between speed and data protection from unauthorized access.
⚠️ Attention: If you're using the same network name (SSID) on both routers, make sure the channels match. Some older devices may become confused when switching between access points with the same name but different channels.After setting up security, be sure to reboot the device through the menu
System Tools → RebootThis will commit all the changes you made and start the services in the correct order.Device placement and influencing factors
The efficiency of the repeater directly depends on its location. TP-Link TL-WR740N It should be located within the main router's strong signal range, but closer to the "dead zone." If it's placed too far away, it will transmit a weak and noisy signal, which won't improve speed.
The ideal location is midway between the main router and the problem room. Be aware of any physical obstructions: mirrors, aquariums, microwaves, and thick concrete walls significantly weaken the 2.4 GHz signal. Router antennas should be pointed vertically upward for maximum coverage.
Factors that degrade the signal:
- 🧱 Wall material: Rebar and brick dampen the signal more than drywall.
- 📺 Household appliances: An operating microwave oven creates strong interference in the 2.4 GHz range.
- 📶 Neighborhood networks: A large number of networks on one channel reduces speed.
Troubleshooting and Common Mistakes
Even with proper setup, issues may arise. If you have internet access through the repeater but the speed is slow, try changing to a less crowded channel. In the 2.4 GHz band, only channels 1, 6, and 11 do not overlap. Using intermediate values (such as 3 or 9) can lead to partial spectrum overlap and reduced performance.
A common mistake is leaving the DHCP server enabled on the repeater. In this case, devices will receive incorrect settings and will not be able to access the internet, although they will still be able to connect to the router. Always ensure that DHCP is enabled on TL-WR740N disabled.
Firmware is also worth mentioning. If you're using a very old version of the software, WDS functionality may become unstable. Check the firmware version on the sticker and, if necessary, update the firmware through the menu.
System Tools → Firmware Upgrade, by downloading the file from the manufacturer's official website.⚠️ Attention: When updating the firmware, do not interrupt the router's power supply under any circumstances. This could cause irreversible damage to the device ("bricked"), which will be impossible to repair without specialized equipment.FAQ: Frequently Asked Questions
Will the Internet work if the main router is turned off?
No, TP-Link TL-WR740N In repeater mode (WDS), it doesn't create an internet connection on its own. It only extends the main router's signal. If the main internet source is disconnected, the repeater won't broadcast anything.
Is it possible to connect routers with a cable instead of over the air?
Yes, that's even better. In that case, you need to configure TL-WR740N As an access point: disable DHCP, change the IP address, and connect the LAN ports of both routers with a cable. This will ensure maximum speed.
Why is the speed through a repeater lower than directly?
In WDS mode, the channel's throughput is split in half, as the radio module simultaneously transmits and receives data. Interference and distance also play a role.
Will this instruction work for TL-WR740ND version?
Yes, model TL-WR740ND It differs in having a removable antenna, but the software and WDS settings are completely identical to the version without the letter "D".
