Hi. My name is***** you for your question and the opportunity to assist.
When the RE6700 is powered on it starts broadcasting a wireless network called Linksys Extender Setup
On a wireless laptop or PC, connect to Linksys Extender Setup
Once connected, open a browser and enter in the address bar: http://extender.linksys.com
and press Enter
This will take you to a Linksys page.
Click Start and accept the license agreement. You'll then choose your existing wireless network
from the list and connect the extender to it.
