Would a Netgear range extender, for example WN2000RPTv2, create a separate network? I wasn't able to tell by looking at the user manual online. How do these things generally work? Does it just, as the name implies, amplify/extend the same network, or is it possible to configure it to function as a router (with its own private subnet, NAT, DHCP, etc.), treating the main network (the one being extended) as a router normally treats the outside world?
So...if I was using an extender to extend a freely available, widely available unprotected wireless network, would the devices connected via the extender be accessible from other devices on the main network that are not connected via the extender? Is there any difference between being attached to the main network, and being attached via the extender? Is the sole purpose of configuring the wireless "security" settings on the extender just to prevent others from using the extender, or is there indeed a private network being created just for the extender clients?
In other words, is there any security difference on a given PC if it connects via an extender vs. just connects directly to the original network?
