general iperf HOWTO

A quick google for "iperf site:cwna.com" didn't show up anything, so I thought I'd link to one of my favorite tools when evaluating wireless networks.
Here's a quick HOWTO (assuming you're using Windows)
(1) drop iperf.exe in %system%system32
(2) do step one on two computers, one which will be moving around (e.g. your laptop) and one that remains stationary
(3) on the stationary computer, type in the following to have it listen for traffic (192.168.1.100, in my case)
iperf -s
(4) on the moving computer (192.168.1.119, in my case), type in "iperf -c (IP of stationary computer)", and you should get an output similar to the following:
iperf -c 192.168.1.100
------------------------------------------------------------
Client connecting to 192.168.1.100, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1908] local 192.168.1.119 port 1934 connected with 192.168.1.100 port 5001
[ ID] Interval Transfer Bandwidth
[1908] 0.0-10.0 sec 23.8 MBytes 19.9 Mbits/sec
This is about what I'd expect, considering I'm one room away from the 802.11g wireless router that I'm using.
(Those wanting more details on how to use the tool should check out this iperf FAQ. There are several great examples on how to use the other switches.)
