The WRE6605 allows you to easily extend existing 2.4G, 5G, or dual band wireless networks. Simply plug
the WRE6605 directly into a power outlet and the LED signal strength indicator allows you to determine
the ideal installation location. The one-click Smart Push Button (Smart Push Button on page 11) lets you
set up secure, simultaneous 2.4G or 5G uplink connections to your wireless router or AP and once this is
completed, set up secure simultaneous 2.4G or 5G downlink connections to your wireless clients. You
could use the 2.4G band for regular Internet surfing and downloading while using the 5G band for time
sensitive traffic, such as high-definition video streaming, and big size file transfers.
As shown in the figure below you can set up your WRE6605 to work as a repeater or an access point.
Figure 1 Repeater Application
