Arris Modem Not Working with WiFi Extender: Do This!

If you’re struggling to get your Netgear extender connected with the Arris modem, then you must ensure that you’re following the right steps for the setup. A Netgear extender can be configured using the WPS method, the Nighthawk app or the web interface. You can use any method that you like. The WPS method is considered to be the best one of all for the Netgear wifi extender setup. But the modem should be WPS enabled for you to use this method.

Netgear Extender Setup Using WPS Buttons

Try the steps given below for the Netgear extender setup:

  • The Arris modem and Netgear extender should sit next to each other while you’re trying to connect them.
  • Plug the devices to supply power to them.
  • Now, locate and press the WPS button on the extender.
  • Within 2 minutes, you need to press the WPS button on the second device i.e. the Arris modem. Do not exceed the time limit.
  • Wait for the devices to establish the connection.

Is the Arris modem not working with the Netgear WiFi extender even now? Have you failed to set up your extender? Try using the web UI or the Nighthawk app now. In case the process isn’t getting executed by any method then apply the solutions listed next.

1. Consider Examining the Power Sockets

You should have the Netgear wireless extender and the Arris modem fully booted up while you’re trying to connect them. You can confirm this by observing the Power LEDs on them. It is recommended to try plugging the devices into some other wall outlets to supply power to them. Damage in the sockets may not be visible directly to our eyes. So, using alternative sockets may be helpful. In case there are fluctuations in the power supply, then use a UPS.

2. Try Making a LAN Connection

You can connect the WiFi extender to the modem with the help of a LAN cable before you carry out the setup instructions using the mywifiext.net web interface or the app. We suggest you opt for a wired connection as the chances of getting setup issues are reduced this way. However, you must form a firm connection using a good LAN cable and make use of the right ports.

3. Reset Netgear WiFi Extender

It is possible that the extender is an old one or while you are trying to execute the setup there are some configurations stored on it that are stopping the connection. For a WiFi extender to be set up, it should have the default factory settings running on it. To have the default settings restored on it, perform a factory reset.


To reset your extender,

  • Detach all the cables from it except the power cable.
  • Now, press the Reset button on it. You can locate it inside a hole. Since it is in a tiny hole, use a sharp object.
  • Hold it for 10 seconds at least.

The Netgear wireless extender resets this way. All the custom configurations are removed. You can now easily set it up with Arris modem without getting stuck in between. Just follow the right setup instructions.

Netgear Extender Setup Using Web UI

  • Unplug the devices for some time first.
  • Make use of a LAN cable, link the Internet port and the LAN port of the extender and modem respectively.
  • Now, plug in the devices to switch them on.
  • When the extender is fully boots up, connect your phone or computer to its WiFi. It is recommended to connect the computer using an Ethernet cable.
  • As soon as you’re connected, you will have the New Extender Setup page appearing on a browser.
  • If the page does not appear then visit mywifext.net on the browser.
  • You can also use the Nighthawk app. Simply run the app on your phone after connecting it to the extender’s WiFi.
  • Execute the setup instructions on the browser or app.
