Frequently Asked Questions - MX21 Pro Tenda

How to install the Tenda MX21 Pro system?

Connect the primary node to the modem with the Ethernet cable, then use the Tenda WiFi app or web interface (tendawifi.com) to complete the setup.

What to do if the LED blinks green continuously?

This means the node is not yet connected to the Internet. Check the Ethernet connection and follow the setup steps in the app or web interface.

How to extend the network with additional nodes?

Place the other nodes within 3 meters of the primary node, turn them on, and wait about 3 minutes. The LEDs become solid green if the connection is successful. Then move them to their final location.

Solid green: excellent connection. Solid yellow: fair connection. Solid red: poor connection. If the light is red, move the node closer to the primary.

How to reset the node to factory settings?

Press the Reset button on the back of the node for about 10 seconds until the light blinks. Release, the device restarts.

Can I use the system without a modem?

Yes, if you have a wall Ethernet port (Internet port), directly connect the primary node with the Ethernet cable. Ignore the steps about the modem.

How to access the web interface if the tendawifi.com URL does not work?

Make sure you are connected to the node's WiFi network. If the problem persists, consult the device's FAQ or use the IP address 192.168.0.1 in the browser.

Can I use the system with another router?

Yes, the primary node can be connected to the LAN port of your existing router to create an extended mesh network. Configure it as access point mode if necessary.

How to change the WiFi password?

Open the Tenda WiFi app, go to network settings, and change the SSID and password. All nodes share the same credentials.

Extend network

1. Place the other devices in the kit within 3 meters from the primary node to power them on. Wait for about 3 minutes. When the LED indicators of these devices light solid green, the networking is successful and these devices become secondary nodes in the network.

LED indicator

1. Please refer to the following relocation tips to locate the secondary nodes to a proper position:

2. Ensure that the distance between any two nodes is less than 10 meters.

3. Keep your nodes away from electronics with strong interference, such as microwave ovens, induction cookers, and refrigerators.

4. Place the nodes in a high position with few obstacles.

5. Power on the secondary nodes again till these LED indicators blink green slowly.

The MX15 Pro(3-pack) is taken as an example here.

Tips

If the LED indicator of secondary node keeps blinking green slowly for more than 3 minutes, relocate the secondary node and move it closer to the primary node.

1. Observe the LED indicator of the secondary nodes until the LED indicator lights one of the following colors:

Solid green Networking succeeds. Excellent connection quality.

Solid yellow Networking succeeds. Fair connection quality.

Solid red Networking succeeds. Poor connection quality.

1. If the secondary node's LED indicator lights solid red, relocate it according to step 2 in 🌐 Extend network to get an optimal connection quality.

Done.

• To access the internet with:
