Set the Access Point/Extender Switch
To use the extender in extender mode, set the Access Point/Extender
switch to Extender .
Place the Extender and Supply Power
1. Place your extender in the same room as your WiFi router.
Proximity to the WiFi router is required only during the initial setup
process.
2. Plug the extender into an electrical outlet.
Wait for the Power LED to light green. This might take up to
100 seconds. If the Power LED does not light, press the Power On/
Off button on the side of the extender.

6
Connect to an Existing WiFi Network
To extend the range of your WiFi network, you must connect the extender
to your existing WiFi network. You can do this in one of two ways:
• Connect with WPS. For more information, see the following section.
• Connect with the NETGEAR installation assistant. For more
information, see Connect With the NETGEAR Installation Assistant on
page 9.
Connect With WPS
Wi-Fi Protected Setup (WPS) lets you join a secure WiFi network without
selecting the network name and entering the password.
Note: WPS does not support WEP network security. If you are using WEP
security, follow the instructions in Connect With the NETGEAR Installation
Assistant on page 9.
1. Press the WPS button on the extender.
The WPS LED blinks.
2. Within two minutes, press the WPS button on your router or access
point.
The WPS LED on the extender lights solid green, the Router Link LED
lights, and the extender connects to your existing WiFi network.
If the Router Link LED does not light, try again. If it still does not light,
see Connect With the NETGEAR Installation Assistant on page 9.

7
3. If your WiFi router supports the 5 GHz band, repeat Steps 1 and 2 to
connect the extender to the 5 GHz band.
Note: If your router supports the 5 GHz band, your extender
attempts to connect to the router’s 5 GHz band the first time you
press the WPS button. If your extender did not connect to the router’s
5 GHz band the first time, repeat the WPS process.
4. Unplug the extender and move it to a new location that is about
halfway between your router and the area with a poor router WiFi
signal.
The location that you choose must be within the range of your
existing WiFi router network.
5. Plug the extender into an electrical outlet and wait for the
Power LED to light green.
6. Use the Router Link LED to help you choose a spot where the
extender-to-router connection is optimal.
7. If the Router Link LED doesn’t light amber or green, plug the extender
into an outlet closer to the router and try again.
Router Extender Computer

8
Keep moving the extender to outlets closer to the router until the
Router Link LED lights amber or green.
8. Connect your WiFi-enabled computer or mobile device to the WiFi
network.
Note: Your extender uses the same WiFi network settings as your
router for its 2.4 GHz and 5 GHz extended networks.
For example, if your extender connects to the router’s 2.4 GHz WiFi
band, your extender uses your router’s 2.4 GHz WiFi settings for both
its networks:
• Router 2.4 GHz WiFi network name. MyWiFiExample
• Router 5 GHz WiFi network name. MyWiFiExample-5G
• Extended 2.4 GHz WiFi network name. MyWiFiExample
• Extended 5 GHz WiFi network name. MyWiFiExample
If your extender connects to the router’s 5 GHz WiFi band, your
extender uses your router’s 5 GHz WiFi settings for both its networks:
• Router 2.4 GHz WiFi network name. MyWiFiExample
• Router 5 GHz WiFi network name. MyWiFiExample-5G
• Extended 2.4 GHz WiFi network name. MyWiFiExample-5G
• Extended 5 GHz WiFi network name. MyWiFiExample-5G

9
Note: Since your router and extended networks share the same WiFi
network name, only one WiFi network name is broadcast.
Connect With the NETGEAR Installation Assistant

Frequently Asked Questions
You can find more information about your product in the user manual,
which is available at www.netgear.com/support.
The NETGEAR installation assistant 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. For more information, see Place the Extender
and Supply Power on page 5. If you are using WEP security, make sure
that you are typing the network password in the correct field.
Can I set up the extender in extender mode if I connect it to the

I enabled a WiFi MAC filter, wireless access control, or access
control list (ACL) on my router. What should I do when installing
the extender?
When a device connects through the extender to your router, the MAC
address of the device shown on the router is translated to another MAC
address. If your router’s MAC filter, wireless access control, or ACL is
enabled, the device connects to the extender but cannot get an IP address
from the extender and cannot access the Internet.
To allow your device to receive an IP address from the extender and access
the Internet, you must provide the translated MAC address to the router.

18
1. Log in to your router and disable the MAC filter, wireless access
control, or ACL.
For more information about how to disable your router’s MAC filter,
wireless access control, or ACL, see your router’s documentation.
2. Power on the extender and connect all of your devices to the
extender network.
