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.

FAQ

This section provides answers for difficulties you might experience with the extender.

The web browser setup 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 about where the place the extender, see Find the Best Location on page 13.
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 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 Use the Extender in Access Point Mode on page 14.

I forgot my login email address and password. What can I do?

On the login screen, click the Username & Password Help link to answer the security
questions that you set up during the initial setup. For more information, see Recover a Forgotten User Name or Password on page 34

If you cannot connect to the extender, determine what prevents you from connecting:
• If you forgot your user name or password, click the Username & Password Help link.
For more information, see FAQs on page 43.
• If your browser displays an error page, include http:// in the address field of your browser
by typing http://www.mywifiext.net.
• If you already set up the extender but can no longer connect to it over WiFi, check to see
if the Device Link LED is off or red.
• If you cannot get a WiFi connection working, you can use an Ethernet cable to connect
your computer to the extender.

Cannot Join a WiFi Network and Receive an Error Message

To join a WiFi network, you must know its network name (also called the SSID) so that you can select it. If the network is secure, you must know the passphrase or key. If the extender does not connect to the network that you select, the cause might be one of the following:


• It is possible that you typed the network name, passphrase, or key incorrectly. Use Smart
Setup (see Run Smart Setup Installation on page 17) to select a WiFi network and retype the passphrase or key. The passphrase or key is case-sensitive. For example, PASSWORD25 is not the same as Password25 or password25.


• If the AC750 extender cannot detect your WiFi network, check to see if your WiFi network is still working. Make sure that the WiFi router is turned on. If possible, move the extender closer to the WiFi router.


• If the AC750 extender Device Link LED is red, the WiFi connection between the WiFi router and the extender is poor. You can establish the best connection with a clear line of sight between the extender and the WiFi router. Make sure that no physical obstacles exist between the extender and the WiFi router, and try to move the extender closer to the WiFi router.

If you use Smart Setup, and the extender does not connect to the WiFi router, does not connect to the Internet, or cannot get an IP address from the WiFi router, Smart Setup displays a message to notify you that the extender is not configured.

To run Smart Setup again, click the YES button. To manually configure the extender, click the NO, CONFIGURE MANUALLY button.
