Creating a New or Extending an Existing Network

Keenetic routers deliver reliable, continuous, and secure Wi-Fi throughout your home. Starting with one main Keenetic router, as your demands increase, you can add more Keenetic devices to act as Wi-Fi extenders to create a centrally-managed multi-node Mesh Wi-Fi System.

If you are creating a new network and this Keenetic Challenger SE (hereinafter `Keenetic device’) is going to be your Main Router, use the switch position A .

If you are extending an existing network and this Keenetic device is to act as a Wi-Fi extender, turn the switch to position B.

A. Connecting Your Keenetic Challenger SE to the Internet

1. Set the physical Operating Mode Switch located on the back panel to position A — Router Mode.

2. Position your Keenetic device within cable lengths of Ethernet and power outlets. Place your Keenetic device in an unenclosed space for better wireless coverage. Connect your Keenetic device to a power source. Check that the Status LED is on and solid orange or green.

3. onnect a mobile device to your Keenetic device via Wi-Fi. The default Wi-Fi name (SSID) and the Wi-Fi password are printed on your Keenetic device’s back label along with a QR code that will automatically connect your mobile device to the Keenetic device’s Wi-Fi when scanned. Alternatively, onnect a computer to the gray Ethernet port on your Keenetic device using the included Ethernet cable.

Then, enter that IP address in the web browser to open the Web Interface on the Keenetic Extender to make necessary changes.

What should I do if I forget my wireless password?
The default password for connecting to your Wi-Fi network can be found on a sticker on the back of your Keenetic device, or if you are using a Mesh Wi-Fi System, you should use the password on the Main Router. If the default Wi-Fi password has been changed and subsequently lost, the changed password can be retrieved or reset by logging in to the web interface or in the Keenetic mobile application.

What should I do if I can’t add an extender to the Keenetic Mesh Wi-Fi System?
Make sure the Operating Mode Switch on the case is set to B — Extender Mode. If this is correct then next restore the factory settings of your router (see below), and repeat the procedure of adding the extender to the Mesh Wi-Fi System.

What should I do if I forget my Web Interface page password?
To create a new password, please follow the instructions to restore the factory settings on your Keenetic device in the question below.

How do I reset/restore the original factory settings on my Keenetic device?
Make sure that your Keenetic device is connected to a power supply. Press and hold the Reset Button until the Status LED begins to blink rapidly, release the button and wait while your device restarts.
Important: After restoring factory settings, you will need to reconfigure your Internet connection and re-add extenders to your Mesh Wi-Fi System.
