d. Replace the first two hexadecimal values in the old MAC 1 address with the new 
value you converted and add the new MAC 1 address to your router’s MAC filter 
table.
For example, if your old MAC 1 address was C4:04:15:5F:20:AD, your new MAC 1 
address is C6:04:15:5F:20:AD.
12. Enable the router’s MAC filter, wireless access control, or ACL.
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 68.
•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 Link Rate 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 21) 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 Link Rate 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.
