1. Compatibility of TP-Link amplifiers with Xiaomi routers: what you need to know before buying
Not all TP-Link repeaters work equally well with Xiaomi routers.
- 📶 Wi-Fi standard: Make sure the amplifier supports the same standard as the router. AX3600 (Wi-Fi 6), then TP-Link repeater RE605X (Wi-Fi 6 is better than the older model. TL-WA850RE (Wi-Fi 4).
- 🔒 Type of encryption: Xiaomi routers of the latest versions often use WPA3, And budget repeaters -- only WPA2. This does not block the connection, but can slow down the speed.
- 🌐 Dual-band support: If the router is running in two bands (2.4 GHz and 5 GHz), choose a repeater with the same function (e.g. TP-Link). RE450), keep up.
| Xiaomi router model | Recommended TP-Link model | Max, speed paired. | Notes |
|---|---|---|---|
| Xiaomi Mi Router 4A | TP-Link TL-WA850RE | 300 Mbps | Budget solution for small apartments |
| Xiaomi AX1800 | TP-Link RE305 | 1200 Mbps | Support for Mesh Networks (requires firmware updates) |
| Xiaomi AX3600 | TP-Link RE605X | 1800 Mbps | Best for large homes (Wi-Fi 6) |
Important: If your Xiaomi router is running 802.11r (Fast Roaming, some TP-Link repeaters may not support this standard. 802.11r in the router settings before connecting the amplifier.
2. Method 1: Connecting through WPS (fastest)
Technology WPS (Wi-Fi Protected Setup allows you to connect the repeater to the router in 30 seconds without entering a password:
- ✅ It only works if the router supports it. WPS (It is enabled by default on most Xiaomi models).
- ❌ Not suitable for networks with WPA3 (You'll have to switch temporarily. WPA2).
- ⚠️ Some TP-Link repeaters (e.g, RE220) require the press of a button WPS within 2 minutes after switching on.
Step-by-step:
- Place the TP-Link repeater in the socket next to the router (no further than 1-2 meters).
- Press the button. WPS on the back of Xiaomi router (usually marked with an icon) 🔄). Hold for 3-5 seconds until the indicator starts to blink.
- Press the button for 120 seconds. WPS on the TP-Link repeater (on some models the button is combined with Reset - hold 1 second).
- Wait until the repeater lights up blue (successful connection) or red (error).
If the indicator flashes orange, it means that:
- 🔹 The router and the repeater are too far apart.
- 🔹 The router's settings are off. WPS (Check in the settings → Wi-Fi → WPS).
- 🔹 Incompatible encryption standard is used (try changing it). WPA3 on WPA2-PSK).

Method 2: Manual connection via web interface (most reliable)
If WPS If it doesn't work or your router doesn't, you can use manual configuration, and this method gives you more control over network parameters, like the range (2.4 GHz or 5 GHz) and the type of encryption you want.
Step 1 Connect to the repeater network
By default, the TP-Link amplifier creates its own network with the name of the view. TP-Link_Extender_XXX. Connect to it from your phone or computer. the password is usually indicated on the device sticker (for example, admin or admin). 12345678).
Step 2. Log in to the repeater web interface
Open your browser and go to:
http://tplinkrepeater.netor IP-address:
192.168.0.254If the page does not open, check the connection to the repeater network or reset its settings (Reset button for 10 seconds).
Step 3: Select the Xiaomi router network
In the repeater interface:
- Go to the Quick Setup section → Next.
- Select from the list the network of your Xiaomi router (for example, Xiaomi_ABCD).
- Enter the password from the Wi-Fi router.
- Set up the name of the new extended network (you can leave the same as the router, or add a suffix _EXT).
- Save the settings and wait for the repeater to restart (1-2 minutes).
What if the repeater doesn’t see the router’s network?
Step 4. Check the connection.
After the repeater reboot:
- 📱 Connect to an extended network (for example, Xiaomi_ABCD_EXT).
- 🌐 Open your browser and check the Internet access.
- 📊 Go to the repeater settings (tplinkrepeater.net) and look at the signal level in the Status section: ≥ 70%.
💡
If the internet speed has dropped after the connection, try turning off Band Steering (automatic switching between bands) in the repeater settings. This often helps when working with Xiaomi routers.
Method 3: Configure via Tether mobile application
The TP-Link Tether app (available for Android and iOS) makes it easy to set up a repeater, especially if you don't want to mess with the web interface.
- 📱 The application may not see the repeater if it is connected to a 5 GHz network. In this case, temporarily use 2.4 GHz.
- 🔄 If the Xiaomi router uses non-standard Wi-Fi channels (for example, 165 in the 5 GHz band), the application may give an error. Solution: manually set the channel 36-48 in the router settings.
Instructions:
- Download and install TP-Link Tether from Google Play or the App Store.
- Connect to the TP-Link repeater network (as in Method 2).
- Launch the app and select your repeater from the list.
- Follow the customization wizard: Select Xiaomi network, enter a password, and save the changes.
Important: When configured through the app, the repeater can automatically update the firmware, which will take up to 5 minutes. Don't turn off the power at this point!
5. Optimal placement of the amplifier: how to avoid loss of speed
The wrong location of the repeater is the main cause of low speed and unstable signal.
- 📍 Area overlap: The repeater must be at the border of the coverage area of the router. If the router signal at the site of the installation of the repeater is weaker than 50%, the speed will drop 2-3 times.
- 🚫 Avoid obstacles: Concrete walls, metal doors and mirrors weaken the signal; Optimally, direct visibility between the router and the repeater.
- ⚡ Power: Don't use extension cords or network filters, they can cause interference. Connect the repeater directly to the socket.
| Distance from router | Signal level | Recommendation |
|---|---|---|
| 0-5 meters | 90–100% | Too close - no repeater needed |
| 5–15 meters | 70–90% | Perfect location |
| 15-25 meters | 30–70% | Speed will drop by 30 to 50 percent. |
| > 25 meters | < 30% | The repetitive will not be able to work stably. |
To check the signal level:
- Connect to the repeater network.
- Go to its settings (tplinkrepeater.net).
- Go to the Status section → Wireless and see the Signal Strength option.
💡
If the signal level between the router and the repeater is below 50%, try moving the amplifier closer or using alternative solutions (e.g. Mesh or Powerline adapters).
Typical errors and their solution
Even after you've set it up properly, you can have problems.
⚠️ Note: If the TP-Link repeater is permanently disconnected from the Xiaomi router, check the settings DHCP Some Xiaomi firmware limits the number of connected devices. Solution: Increase the limit in Settings → Local area network → DHCP.
| Problem. | Possible cause | Decision |
|---|---|---|
| The repeater does not connect to the router | Incompatible encryption standard (WPA3) | Switch the router to the router. WPA2-PSK safety-setting |
| Low Internet speed | The repeater operates in the 2.4 GHz band with a loaded channel | Manually select channel 1, 6 or 11 in router settings |
| Frequent connection breaks | Too much distance between devices | Move the repeater closer to the router (50-70% of the distance to the dead zone) |
| Repiter doesn't give away the internet | Absent. IP-address (problem with DHCP) | Restart router and repeater, check settings DHCP |
If nothing helps:
- 🔄 Update the repeater firmware (System Tools section) → Firmware Upgrade).
- 📋 Reset the repeater to factory settings (reset button for 10 seconds) and repeat the setting.
- 🔧 Check your Xiaomi router settings for features like AIoT or Mi Mesh – they can block third-party connection.
7. Alternative solutions if the repeater is not suitable
If the TP-Link amplifier fails to do the job (for example, because of the large area of the house or thick walls), consider alternatives:
- 🌐 Mesh system: Xiaomi routers (for example, AX3600) Mesh support. You can add a second Xiaomi router in repeater mode, which will give more stable coverage than the repeater.
- ⚡ Powerline adapters: Wire the Internet over electrical wiring, suitable if the Wi-Fi signal does not pass through walls (for example, TP-Link). AV1000).
- 📡 Directed antenna: If the problem is in one direction (for example, the signal does not finish before giving), use a router with an external antenna (for example, TP-Link). CPE210).
To configure the Mesh network on Xiaomi routers:
- Connect the second Xiaomi router to the main one via cable or Wi-Fi.
- Go to the settings of the main router: Settings → Mode of work → Mesh.
- Follow the Connection Wizard. The second router will automatically copy the network settings.
💡
If you use a TP-Link repeater in a large house, try turning on the mode. AP Mode (access point) and connect it to the Xiaomi router via Ethernet cable.
