measure thruput between wireless card and wap

Is there software that will measure the speed between my wireless
access point and my laptop?
Thanks in advance

Yeah, you can use iPerf, install it on your laptop and a wired machine,
and run it. Works really well.

I have the iperf executable but I don't know how to use it.
Can you give me a little direction.
Thanks in advance!

Well, it's fairly simple. You just need to do the following:

1) On the wired machine run "iperf -D"
2) On the client/wireless machine run "iperf -c [wired machine ip]"

Note that Iperf will give you the speed between two computers and not
between the wireless access point and a wireless client. In order to
get meaningful results from a high speed wireless connection, you need
to have the test server connected with 100baseTX-FDX (full duplex) to
the LAN ports on the wireless router. That will usually give about
80-90Mbits/sec on the 100baseTX-FDX end. If the wireless part is
connected at 54Mbits/sec, you should get about 25Mbits/sec thruput.
The LAN connected server computer has to be capeable of higher speed
than the wireless computer or the results are worthless.

See:

for IPerf examples.

Taking a moment's reflection, NetSteady mused:

Might have better results using the "-s" flag instead of "-D" if on
Win OS.

| 2) On the client/wireless machine run "iperf -c [wired machine ip]"

Yeah, that would prolly work better

Unless you need precise results, just use the free Qcheck:

It gives you a ballpark speed.
