Power Light Status/ description Blinking Green  Booting up  Resetting to factory defaults  Upgrading firmware Solid Green  Ready to use Solid Orange  Weak connection with the router Fix: Unplug the extender, and move it closer to the router Blinking Orange  Not connected to the router  Other error Fix: Unplug the extender, plug it back in, wait two seconds, reconnect to your network Side Power Switch European versions only. Wi-Fi Protected Setup Button and LED Use Wi-Fi Protected Setup to automatically and securely add compatible wireless devices to your network. Refer to Using Wi-Fi Protected Setup on page 7. Reset Press and hold for about five seconds to reset to factory defaults. You can also restore the defaults from the Administration > Factory Defaults screen in the extender’s browser-based utility. Bottom Ethernet (blue) Connect wired devices to your wireless network with Ethernet (network) cables. The green light turns on when an Ethernet device is connected and active on this port. The light blinks when the extender is sending or receiving data over the Ethernet port. How to install the range extender Before setup, unplug or disconnect any range extenders on the network. 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. <Diagram> 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.” <diagram2> 3. If setup doesn’t start automatically, open a browser to http://extender.linksys.com. Linksys’s Spot finder technology will help you find the right location for your range extender if you have trouble. You will be guided to place the range extender closer or farther from your router to improve the signal. If you nailed it with your first placement you will not see Spot finder screens. <screenshot of Too Far page> 4. During setup you will be asked whether you want the range extender to update itself automatically. If you allow automatic updates, the range extender will download and install updates when released by Linksys. Automatic updates will take place overnight so they do not disrupt your network activity. You also can decide to manually update your range extender at your convenience. <screen shot> Post set-up LED behavior mention here as well and in the QSG TIP You can also connect the range extender by using Wi-Fi Protected Setup. For more information, see “Using Wi-Fi Protected Setup” on page 7.
