When to Use Your Extender

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 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.

Detailed Specifications

Key features of the Netgear AC750 WiFi Extender EX3800 include support for dual-band WiFi (2.4GHz and 5GHz), a speed of up to 750Mbps, external antennas for enhanced coverage, and a FastLane technology for seamless streaming and gaming. This device also supports WEP and WPA/WPA2 wireless security protocols, ensuring your network is always protected. Additionally, it comes with a convenient Ethernet port for connecting wired devices.

Get Started

Install the WiFi Extender

Place the extender, apply power, and connect the extender to your 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. .

Place the Extender and Apply Power

To place the extender and apply power:

Place your extender in the same room as your WiFi router.
Proximity to the WiFi router is required only during the initial setup process.
Plug the extender into an electrical outlet.
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.

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.
Connect with web browser setup.

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.

To use WPS to connect the extender to your WiFi router:

Press the WPS button on the side panel of the extender. The WPS LED blinks.
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.
If your WiFi router supports the 5 GHz band, repeat Steps 1 and 2 to connect the extender to the 5 GHz band.
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 _EXT at the end of the name.
For example:
- Existing WiFi network name. MyNetworkName
- New extended network names. MyNetworkName_2GEXT and MyNetworkName_5GEXT\
Connect your computer or WiFi devices to the new extended WiFi network.
Use the same WiFi password that you use for your WiFi router.
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.
Plug the extender into an electrical outlet.
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.
Use the Router Link LED on the front panel to help you choose a spot where the extender-to-router connection is optimal.
