measure thruput between wireless card and wap

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.

Taking a moment's reflection, NetSteady mused: | | 1) On the wired machine run "iperf -D"

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]"

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

It gives you a ballpark speed.
