How to manually pair the G.Hn Wireless Extender with the C4000 router

The G.Hn Wireless Extender kit auto-pairing feature is not compatible with the Greenwave C4000 router. We recommend using another brand of router with the WiFi extender, such as the Zyxel C3000Z or the Actiontec C3000A. However, advanced users may attempt to configure the devices themselves, following the instructions below. 

1.  Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.

2.  Open a web browser and type into the web address field.

3.  Log in to your modem's online settings interface (Modem GUI) using your Administrator Username and Administrator Password. Unless you have changed the default settings, you can find this information on the sticker on the bottom of the C4000. 

4.  Select "Wireless Setup" from the main settings menu.

5.  Make a note of your wireless network name (SSID) and password (security key), as you will need these later.

6.  Next, go the Modem Status menu from the C4000 main page and select "Device Table."

7.  In the Device Table, select the device named CTLAP and record the IP address (it will look similar to the sample, "").

8.  Now, enter that IP address (for CTLAP) into your web browser. This will bring you to the settings portal for the Actiontec G.Hn extender (AP Configuration). Enter the Admin Username and Admin Password found on the label on the side of your G.Hn WiFi Extender.

9.  From the G.Hn settings main page, select the Wireless Setup option.

10. Update the network name (SSID) with the one you recorded in step 5 from the C4000.

11.  Finally, select "Use Custom Security Key/Passphrase" and enter the one recorded in step 5.

12.  Select "Apply" to save your changes.
