If you've installed the Linksys extender to an existing network that your router has created just now, then here it is for the basic knowledge: the router and the extender will have the same name and password on this network. If it is connected successful, that will extend your seamless network speed. However, if you do not have a WiFi router and you want seamless roaming, you can use that extended WiFi for the device's WiFi manager. Any hovering WiFi networks have the ability to use the extension "_Ext" in its name. The password will be the same as that of the main networks. 

 

You should enjoy the WiFi coverage after Linksys re7000 setup. If not, you would have to take a tiny step across yet another Setup. 

 

This means, if you still have no range in the gadget, implement a very simple step. Just start with an opening browser and attempt accessing the device setup page. In case you cannot get through it, and there is an error 404, then put the 192.168.1.1 IP address in URL box. This could be quite handy in surfing around the portal. With a simple username and password, you might access it.
