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 .
If you are extending an existing network and this Keenetic device is to act as a Wi-Fi extender, turn the switch to position .
A. Connecting Your Keenetic Challenger SE to the Internet
- Set the physical Operating Mode Switch located on the back panel to position
— Router Mode.
- 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 LEDis on and solid orange or green.
- Сonnect 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, сonnect a computer to the gray Ethernet port on your Keenetic device using the included Ethernet cable.
- Once connected, an Initial Setup Wizard window will appear on your mobile device / computer. If the Wizard does not appear, using a browser go to my.keenetic.net and follow the setup instructions.

— Extender Mode.
- Connect the ‘Extender’ Keenetic device to a power source. Check that the Status LEDis on and solid orange or green.
- Make sure your Keenetic Main Router is active and has an Internet connection.
Connect the ‘Extender’ Keenetic device to your Keenetic Main Router using an Ethernet cable (as supplied). Alternatively you can connect Keenetic devices wirelessly by placing them near to each other and simultaneously pressing the Wi-Fi Control Buttonson both devices. Check that the Status LED on the ‘Extender’ is illuminated green.
