to the Ethernet port on the extender.
User Manual8Overview
AC1900 WiFi Mesh Extender Essentials Edition

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-enabled 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-enabled device connects to a network.
•The extender acts as an access point for WiFi-enabled 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.

Install your extender in extender mode
To install your extender in extender mode, you must set the Access Point/Extender
switch to Extender.
Place the extender and apply power
To place the extender and apply power:
1. Set the Access Point/Extender switch to Extender.
2. For the initial setup, place your extender in the same room as your WiFi router.
3. Plug the extender into an electrical outlet.
4. Wait for the Power LED to light amber and then turn green.
This might take up to two minutes. If the Power LED does not light, press the Power
On/Off button on the extender.
Connect the extender to an existing WiFi network
To extend the range of your WiFi network, you must connect the extender to your
existing WiFi network.
Note: If your router’s WiFi security is set to WPA enterprise or WPA2 enterprise, your
extender can’t connect to your router. You must change your router’s WiFi security
setting.
You can connect the extender in one of two ways:
•Connect with WPS. For more information, see Connect with WPS on page 11.
Note: WPS does not support WEP network security or a hidden SSID network. If
your router WiFi network uses WEP security or its SSID is hidden, follow the
instructions in Connect with the NETGEAR installation assistant on page 13.
•Connect with web browser setup. For more information, see Connect with the
NETGEAR installation assistant on page 13.

device, check the instructions or online help that came with that device. Some older
equipment cannot use WPS.
Note: WPS does not support WEP network security or a hidden SSID network. If your
existing WiFi network uses WEP security or its SSID is hidden, follow the instructions in
Connect with the NETGEAR installation assistant on page 13.
To use WPS to connect the extender to your WiFi router:
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.
When the extender connects to your existing WiFi network, the WPS LED on the
extender lights solid white and the Router Link LED lights.
If the Router Link LED lights solid green, the connection between your router and
extender is good. If the Router Link LED doesn't light, move the extender closer to
the router and try again.
If it still does not light, see Connect with the NETGEAR installation assistant on page
13.
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 location that you choose must be within the range of your existing 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 help you choose a spot where the extender-to-router
connection is optimal.
6. If the Router Link LED doesn’t light amber or green, move the extender closer to the
router and try again.
Keep moving the extender closer to the router until the Router Link LED lights amber
or green.

automatically from a DHCP server.
2. Connect a computer or mobile device to the extender using a WiFi or Ethernet
connection:
•WiFi. On your WiFi-enabled computer or mobile device, open the WiFi connection
manager and locate and connect to the extender network called NETGEAR_EXT.
When your WiFi-enabled computer or mobile device is connected to the extender,
the Client LED lights solid white.
•Ethernet. Use an Ethernet cable to connect the Ethernet port on your extender
to an Ethernet port on your computer.
3. Launch web browser.
4. Enter http://www.mywifiext.net.

or green.
9. Reconnect your computer or mobile device to the new extender WiFi network.
Install your extender in access point mode
You can use the extender as a WiFi access point, which creates a new WiFi hotspot by
using a wired Ethernet connection. The following instructions assume that this is the
first time you're setting up the extender.
Figure 3. Extender in access point mode
To install your extender in access point mode:
1. Make sure that your computer or mobile device is set up to obtain an IP address
automatically from a DHCP server.

After you complete the setup process, you can connect all your devices to the new
extender network using a WiFi, wired, or WPS connection.
User Manual16Get started
AC1900 WiFi Mesh Extender Essentials Edition

Connect a device to the extender network using WiFi
If you enabled the One WiFi Name feature, your extender uses the same WiFi network
name and password as your router. The following is an example of what your WiFi
network names might look like if One WiFi Name is enabled:
•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-5G
If you set up your extender using WPS, 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
Since your router and extended networks share the same WiFi network name, only one
WiFi network name is broadcast.
To connect to the extender WiFi network:
1. On your WiFi-enabled computer or mobile device, open the WiFi connection
manager that manages your WiFi connections.
The WiFi connection manager scans for WiFi networks in your area.
2. Find and select your WiFi network name (SSID) and enter your WiFi password.
This is the SSID and password that you set up during the installation process.
