 Universal Dual Band WiFi Range Extender WN2500RP
How the Extender Works
The extender works like a bridge between a wireless router and a computer or wireless 
device outside the wireless router’s range. To do this, the extender has two main jobs:
1. 
The extender connects to a wireless network that is up and running. 
When the extender connects wirelessly to a network, it acts as a network client. This is 
similar to how a computer connects to a network. 
2. 
The extender acts as an access point for computers. 
The extender has its own wireless network called NETGEAR_EXT that wireless 
computers can join. In its role as an access point, the extender performs tasks that 
wireless routers do, such as broadcasting its network name (SSID).
The extender needs to do each of these jobs so that both ends of the bridge are in place.
The extender is halfway
between the router
and the computer.
