You can use your extender in extender mode or in access point
mode.
In extender mode, your extender repeats the signals from your
WiFi router. After initial setup, the best location for the extender is
about halfway between your router and the area with a poor WiFi
signal. The extender must be within the range of your WiFi router
network.
In access point mode, your extender creates a new WiFi hotspot by
using a wired Ethernet connection.

Install the extender in extender mode
1. Set the Access Point/Extender switch to Extender .
2. For initial setup, place your extender in the same room as your
WiFi router.
3. Plug the extender into an electrical outlet.
Wait for the Power LED to light green. This might take up
to 2 minutes. If the Power LED doesn’t light, press the Power
On/Off button on the extender.
Continue with installation, using one of these methods:
• To connect your extender using WPS, see the following
section.
Note: WPS doesn’t support WEP network security. If you use
WEP security, you must use the NETGEAR installation assistant.
• To connect your extender using the NETGEAR installation
assistant, see Connect the extender to your WiFi network using
the NETGEAR installation assistant on page 9.

Connect the extender to your WiFi network
using WPS
Wi-Fi Protected Setup (WPS) lets you join a secure WiFi network
without selecting the network name and entering the password.
1. Press the WPS button on the extender until the WPS LED
blinks green.
2. Within two minutes, press the WPS button on your router.
The WPS LED on the extender lights solid green, the Router
Link LED lights, and the extender connects to your WiFi
network.
If the Router Link LED doesn’t light, try again. If it still doesn’t
light, see Connect the extender to your WiFi network using the
NETGEAR installation assistant on page 9.
Note: If your router supports the 5 GHz band and your
extender didn’t connect to that band, repeat the WPS process.
3. 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 extender must be within the range of your WiFi router
network.

4. Plug the extender into an electrical outlet and wait for the
Power LED to light green.
5. Use the Router Link LED to nd a spot where the
extender-to-router connection is optimal.
6. If the Router Link LED doesn’t light amber or green, plug the
extender into an outlet closer to the router and try again.
Keep moving the extender to outlets closer to the router until
the Router Link LED lights amber or green.
7. Connect your WiFi-enabled computer or mobile device to the
WiFi network.
Your extender uses the same WiFi name as your router, based on
the WiFi band that it connects to rst.

FAQs
You can nd more information about your product in the user
manual, which is available at www.netgear.com/support.
The NETGEAR installation assistant keeps asking 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. Move the extender closer
to your router. If you’re using WEP security, make sure that you’re
entering the network password in the correct eld.
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 the extender as an access point on page 11.

16
I forgot my login email and password. What can I do?
On the login page, click the Username & Password Help link to
answer the security questions you set up during the initial setup.
If you forgot the answers to your security questions, you can set up
your login credentials again:
1. Restore the extender to its factory default settings. (See the
following page.)
2. Launch a web browser from a computer or mobile device
connected to your extender network.
3. Log in to your extender:
• If you didn’t enable the One WiFi Name feature, enter
http://mywiext.local/ in the address eld of the browser.
• If you enabled the One WiFi Name feature, enter one of
the following URLs:
-Windows-based computer. http://mywiext/ or
http://mywiext.local/
-Mac computers, iOS devices, and Linux devices.
http://mywiext.local/
-Android devices. http://<extender’s IP address>/ (for
example, http://192.168.1.3/)

17
A login page displays.
4. Click the NEW EXTENDER SETUP button.
5. Complete the elds on the page.
How do I restore the extender to its factory default settings?
1. Use a sharp object such as a pen or straightened paper clip to
press and hold the Factory Reset button on the extender for
at least ve seconds until the Power LED blinks amber.
2. Release the Factory Reset button and wait for the extender to
reboot.
The extender resets and returns to the factory default settings.
I enabled a WiFi MAC lter, 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 lter, wireless access
control, or ACL is enabled, the device connects to the extender
but can’t get an IP address from the extender and can’t access the
Internet.

18
To receive an IP address from the extender and access the Internet,
you must provide the translated MAC address to the router.
1. Log in to your router and disable the MAC lter, wireless
access control, or ACL.
For more information about how to disable your router’s
MAC lter, wireless access control, or ACL, see your router’s
documentation.
2. Power on the extender and connect all your devices to the
extender network.
3. Make sure that the Router Link LED remains lit.
4. Log in to your extender:
• If you didn’t enable the One WiFi Name feature, enter
www.mywiext.net in the address eld of the browser.
• If you enabled the One WiFi Name feature, enter one of
the following URLs:
• Windows-based computer. http://mywifiext/ or
http://mywiext.local/
• Mac computers, iOS devices, and Linux devices.
http://mywiext.local/
• Android devices. http://<extender’s IP address>/ (for
example, http://192.168.1.3/)

19
A login page displays.
5. Select Settings > Connected Devices.
The Connected Devices page displays the MAC addresses and
virtual MAC addresses for the extender, wired devices, and
WiFi devices that are connected to the extender.
6. On the router, add the extender’s virtual MAC addresses and
all the virtual MAC addresses of the devices connected to the
extender to your router’s MAC lter table.
7. Enable the router’s MAC lter, wireless access control, or ACL.
I am connected to NETGEAR_EXT and launched a browser. I
can’t see the NETGEAR installation assistant. What can I do?
Try these troubleshooting steps:
• Make sure that your WiFi-enabled computer is set up to use
DHCP (most are).
• Make sure that the Client Link LED is green and that you’re
using a valid IP address.
• Relaunch the web browser and enter www.mywiext.net in
