How to install the range extender
Beforesetup,unplugordisconnectanyrangeextendersonthenetwork.
1. Plug in the range extender midway between your router and the area without Wi-Fi.
Be sure you have at least 50% of your router’s Wi-Fi signal at that point on the device
you will use for setup. The setup software will help you find the best spot if you have
trouble.
2. Wait for a solid light on the cover of the range extender. It could take up to two minutes.
On a computer, phone or tablet, connect to the Wi-Fi network “Linksys Extender Setup.”
• Windows 7 and Windows 8 will ask you, “Do you want to set up your network?” Click
the link, “Connect to network without setting it up.”
3. If setup doesn’t start automatically, open a browser to http://extender.linksys.com

Connecting the extender to an existing access point
If your access point or router supports it, you can use Wi-Fi Protected Setup to connect
the range extender to the access point or router. Choose from the setup methods
below to connect the extender.
NOTE
If you have an access point or a router that does not support Wi-Fi Protected Setup,
note the wireless settings, and then manually configure the extender.
Connecting with the Wi-Fi Protected Setup Button
Use this method if your router or access point has a Wi-Fi Protected Setup button.
1. Press the Wi-Fi Protected Setup button on the extender.
2. Click the Wi-Fi Protected Setup button on the router’s Wi-Fi Protected Setup
screen (if available), OR press and hold the Wi-Fi Protected Setup button on the
router for one second. When the connection is complete, the Wi-Fi Protected Setup
light on the extender will be solid.
3. If you used the extender’s Wi-Fi Protected Setup screen, click OK in that screen
within two minutes.
NOTE
If you have a dual-band router and wish to connect to both bands, you will have to
perform the WPS setup twice. The first connection will be on the 2.4 GHz band.
Connecting with the range extender’s PIN
The Wi-Fi Protected Setup PIN (Personal Identification Number) can be found on the
product label on the back of the extender. You can use this method only if your router’s
administration utility has a Wi-Fi Protected Setup menu.
1. Enter the extender’s PIN into the appropriate field on the router’s Wi- Fi Protected
Setup screen. Click Register. When the connection is complete, the Wi-Fi Protected
Setup light on the extender will be solid.
2. Click OK.

To open the Site Survey page:
1. Log in to the browser-based utility (see “How to access the browser- based utility”
on page 5).
2. Click the Wireless tab. Click the Site Survey page.
3. Select—To connect to a wireless network, click the button next to the wireless
network name (SSID) in the Select column, and click Connect.
4. SSID—Displays the name of neighboring wireless networks.
5. GHz—Displays the radio band (in GHz) of the neighboring wireless networks
6. Signal Strength—Displays the relative position of the neighboring access points
by indicating the power of the wireless signal received: 1 bar= 20%,2 bars=40%, 3
bars=60%, 4 bars=80%, 5 bars=100%. If no bar is displayed, the extender is located
too far away from the upstream access point. Try to keep the signal strength
between 60% and 100% for optimum performance.
7. Security—Displays the mode of security in use by the neighboring APs. If a network
supports Wi-Fi Protected Setup, the Wi-Fi Protected Setup icon is also displayed.
To connect your extender with an access point or router in Site Survey, you will
need to know the password or passphrase of the network on that device.
1. Select the network name (SSID) that you want to repeat with your extender by
clicking the corresponding button in the Select column.
2. Click Connect. When prompted, enter the password or passphrase used to secure
your wireless network. The type of security information required in this screen must
match your access point or router’s wireless security settings.
3. Click Save. Your extender wireless parameters should be configured. The wireless
interface will restart, and the extender will connect to the access point or router you
have chosen.
6.Cross-Band
Cross-Band is the simultaneous use of both bands for high-speed data transfer and
uninterrupted streaming and gaming.
7.Wireless Music Playback

location.
• To reduce signal obstructions, try alternate locations for the router and extender.
• Avoid placing the router and extender near metal objects, masonry walls,
and reflective surfaces such as glass or mirrors.
