Hey, im trying to do some low level network testing using to raspberry Pi 2's to test wifi throughput over the lan. I am attempting to use Iperf but cant seem to get them to connect to each other.

Anyone have any experience that can assist? Im sure its simple but im a bit of a noob with this..

Im pretty new to the raspberry Pi and have learned a ton already, I mostly use the units I have for work testing purposes and I am looking to use 2 of these to ping a router continuously (a way to keep the wireless client active in the routers eyes) and also gather which wifi channel it is connectin...
