When to Use Your Extender

We recommend that you connect through the extender network only when your WiFi device is in a “dead zone” where connection from the existing network is poor or nonexistent. Data traffic routed through the extender is inherently slower than traffic routed directly from the network.

How the Extender Works

The extender works like a bridge between a WiFi router (or a WiFi access point) and a WiFi device outside the range of the WiFi router. The extender performs two main jobs:
The extender connects to a working WiFi network.
• When the extender connects over WiFi to an existing network, it functions as a network client, similar to how a WiFi device connects to a network.
The extender acts as an access point for WiFi devices.
• The extender broadcasts its own WiFi network that WiFi devices can join. In its role
as an access point, the extender performs tasks that WiFi routers do, such as broadcasting its network name (SSID).
The extender must do each of these jobs so that both ends of the bridge are in place.

FAQs

This section provides answers for difficulties you might experience with the extender.
The web browser setup keeps asking me for my network password (passphrase) or security key, and I am sure that I entered the correct password. What can I do?
The extender is probably placed at the borderline of the range covered by the router or access point. To improve your signal strength, move your extender closer to your router and make sure that the Router Link LED lights solid green or amber. The LED lights as follows:
Solid green. Best connection
Solid amber. Good connection
Solid red. Poor connection
Off. No connection
If you are using WEP security, make sure that you are typing the network password in the correct field.
My router security is WEP, and I entered the wrong password or security key on the extender. I cannot access the extender anymore. What can I do?
The extender cannot check to see if the WEP password is correct. If you entered the wrong password, your WiFi-enabled computer or mobile device is not able to get the IP address from the extender. You must reset the extender to its factory default settings to get the IP address back.
Can I set up the extender in extender mode if I connect it to the router or access point with an Ethernet cable?
No. The extender is designed to connect wirelessly to the router or access point if it is in extender mode. If the extender is in access point mode, you can connect it to the router or access point with an Ethernet connection. For more information about access point mode, see Install your extender in access point mode on page 15.
I am connected to NETGEAR_EXT and launched a browser and I can’t I see the web browser setup guide. What can I do?

Cannot connect to extender using the Nighthawk app

You can use the Nighthawk app to set up your extender and access your extender settings.
If the Nighthawk app is unable to connect to your extender, try these troubleshooting tips:
If you're setting up your extender for the first time, make sure your mobile device is
• connected to the extender WiFi network called NETGEAR_EXT.
If you already set up your extender, make sure your mobile device is connected to
• the new extender WiFi network that was set.
Your extender's WiFi network and password is the same as your router's WiFi network and password.
If you already set up your extender and your extender is connected to a Nighthawk
• router, you can access your extender settings through your router's Network Map
in the Nighthawk app. Launch the Nighthawk app, tap the Network Map on the router dashboard, and then tap the extender icon.
