The EX3920 package includes two model EX3700 WiFi Range Extenders. The extenders boost
your existing network range and speed, delivering dual-band WiFi. You can also use the
extenders in access point mode as a WiFi access point and create a new WiFi hotspot by using
a wired Ethernet connection.

When to Use Your Extenders
NETGEAR recommends that you connect through the extender network only when the 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 Extenders Work
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.
Note: Each extender must connect to your router’s WiFi network. Do not
connect the extenders to another extender’s WiFi network.
The extender performs two main jobs:
•
The extender connects to a working WiFi network.
Overview

AC750 WiF Range Extender
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.

Install the WiFi Extenders
Place the extender, apply power, and connect it to your WiFi network. Each extender must
connect to your router’s WiFi network. Do not connect the extenders to another extender’s
WiFi network.
Note: You can also use the extender as a WiFi access point and create a
new WiFi hotspot by using a wired Ethernet connection. See Use an
Place the Extenders and Apply Power
To place the extender and apply power:
1. Place an 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.
3. Wait for the Power LED to light amber and then turn green.
If the Power LED does not light, press the Power On/Off button on the side of the
extender.
4. Repeat Steps 1–2 for the second extender.
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
Wi-Fi Protected Setup (WPS) lets you join a secure WiFi network without typing the network
name and password.
Note: WPS does not support WEP network security. If you are using WEP
security, follow the instructions in Connect with Web Browser Setup

AC750 WiF Range Extender
To use WPS to connect the extender to your WiFi router:
1. Press the WPS button on the side panel of the extender.
The WPS LED blinks.
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 existing WiFi network.
If the Router Link LED does not light, try again. If it still does not light, see Connect with
3. If your WiFi router supports the 5 GHz band, repeat Steps 1 and 2 to connect the extender
to the 5 GHz band.
4. Find the new extender network name on your computer or WiFi device.
The extender creates two new extended WiFi networks. The extender’s new WiFi
network names are based on your existing WiFi network name, with _2GEXT and
_5GEXT at the end of the name.
For example:
•
•
Existing WiFi network name. MyNetworkName
New extended network names. MyNetworkName_2GEXT and
MyNetworkName_5GEXT
5. Connect your computer or WiFi devices to the new extended WiFi network.
Use the same WiFi password that you use for your WiFi router.
6. Unplug the extender and move it to a new location closer to the area with a poor WiFi signal.
The location that you choose must be within the range of your existing WiFi router
network.
7. Plug the extender into an electrical outlet.
8. Wait for the Power LED to light amber and then turn green.
If the Power LED does not light, press the Power On/Off button on the side of the
extender.
9. Use the Router Link LED on the front panel to help you choose a spot where the
extender-to-router connection is optimal.
10. Repeat Steps 1–9 to connect the second extender.
Connect with Web Browser Setup
You can use a web browser to log in to the extender and set up its WiFi connection to your
existing WiFi router.
To use a web browser to connect the extender to your WiFi router:
1. Use a WiFi network manager on a computer or WiFi device to find and connect to the
extender WiFi network.

If the WiFi signal is weak, the first time you join the extender network, the Router Link LED or
Device Link LED is amber or red. If this happens, adjust the position of the extender:
•
•
If the Router Link LED is amber or red, move the extender closer to the router.
If the Device Link LED is amber or red, move the computer or WiFi device closer to the

technology, the extender connects to your router using one band and connects to your
devices using another band. Because a band is dedicated to each function, performance is
enhanced.
If all your devices and your WiFi router support only the 2.4 GHz band, or all your devices
and your WiFi router support only the 5 GHz band, do not enable FastLane Technology.

Use WPS to Add a Computer to an Extender’s WiFi
Network
WPS (WiFi Protected Setup) lets you connect a computer or WiFi device to the extender’s
network without entering the WiFi network passphrase or key. Instead, you use a WPS button
or enter a PIN to connect.
If you use the push button method, the WiFi device that you are trying to connect must
include a physical WPS button or an onscreen WPS button that you can click. If you use the
PIN method, you must know the PIN of the WiFi device that you are trying to connect.
WPS supports WPA and WPA2 WiFi security. If your extender network is open (no WiFi
security is set), connecting with WPS automatically sets WPA + WPA2 WiFi security on the
extender network and generates a random passphrase. You can view this passphrase on the

You can deny network access to specific computers and WiFi devices based on their MAC
addresses. Each network device is assigned a MAC address, which is a unique 12-character
physical address, containing the hexadecimal characters 0–9, a–f, or A–F only, and
separated by colons (for example, 00:09:AB:CD:EF:01). Typically, the MAC address is on the
label of the WiFi device. If you cannot access the label, you can display the MAC address
using the network configuration utilities of the computer. You might also find the MAC

Use an Extender with MAC Filtering or Access Control
When the WiFi device connects through the extender to your router, the MAC address of the
