FAQs
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 an Extenders in Access Point Mode on page 14.
I forgot my login email address and password. What can I do?
In the login window, 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.
To restore factory settings:
1. Use a sharp object such as a pen or paper clip to press and hold the Factory Reset 
button on the extender for at least five seconds until the Power LED lights amber.
2. Release the Factory Reset button and wait for the extender to reboot.
The extender resets and returns to the factory default settings.
Cannot Connect to the Extender
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 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 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.
