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. 

Not up for the manual pairing challenge? You can also use the TP-Link WiFi range extender with your C4000 modem, available from our Accessories Marketplace.

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.
