To begin with, place the power plug of the Linksys RE6700 extender in a wall socket. After that, grab the computer and connect it to the Linksys extender network. Now, on your WiFi device open the web browser and enter the default web portal. The setup page will open up on your computer display. Next, pick the wireless range extender option. Later, pick the WiFi network that you want to extend. In the prompted field, fill in the password and tap on the connect icon. In the end, wait a while to see the extender successfully connected notification on your computer display. 

Thus, the Linksys RE6700 setup process is done now. In case you fail to connect the Linksys RE6700 extender to the router by trying the above method, consider another configuration method. 

Initially, place your Linksys RE6700 extender closer to the existing router. After that push the WiFi-protected setup button of both the Router and extender units. Now, the WPS LED starts blinking solid. As it means they both are successfully linked with each other. 

Thus, with the help of the above two configuration ways, your device configuration process is completely done now
