It’s not going to be a big deal to setup Linksys Extender RE6500. The WPS method or a browser-based setup are your options and this guide will help you through all the steps needed for a fast and reliable Wi-Fi extension. First of all, you need to plug in the RE6500 close to the router and turn it on. If you use the WPS button, it will be the fastest way — press the router’s WPS button, then the extender’s within two minutes, and look for a solid LED to confirm the connection.

As an alternative, connect to the default Linksys Extender Setup network on your device, launch a browser and type in extender.linksys.com (or 192.168.1.1) to finish the web-based setup wizard.

Once the setup is done, put the extender in the middle of your router and the dead-zone to get the best coverage. The LED indicators can be checked for status — solid white generally means success, while blinking orange may signify connection problems.
