iperf results wired vs wireless ...
-
@BraswellJay That looks about right to me, for that model Cisco (only does A/G/N). Only in theory will you get any faster with that AP (Sitting 2 feet from the AP with no interference.)
-
Looks normal. You should run some ping tests as well. The difference in latency between wired and wireless is HUGE.

Ok, thanks for the feedback.
Would replacing these APs with ubiquiti ac pro devices result in better performance? Would it be reasonable to expect client connections to be faster with an AP that supports AC?
I've got a secondary site that where I have AC Pro AP's so I can test there and see what I am getting at that site with the different access points.
Thanks.

not sure why my dekstop is not near linespeed.
I put the USB to ethernet adapter in my laptop and tested again form that.

That's just shows that the advertised theoretical speed is nothing you ever get, not even if you place them next to each other.
Another thing to take into consideration is that the wireless bandwidth is always shared while the wired bandwidth is not. There might be other constrictions of course in the network path between client and server but those constriction are the same for both.

@Pete-S umm wut? I know exactly what I am reporting here. Did you mean to reply to the OP?
iPerf is the right tool for this job. It tests the line speed (wireless or wired) of connection.
It has nothing to to with day to day speeds, and should not.

Your test was perfect. No, it was meant for the OP or as a general comment.

Ha! Actually my test showed I have some stupid issue on my desktop..
Time to crawl under my desk and poke things.

Am I wrong in thinking that the difference shouldn't be that great?
The expectation is that the difference will be huge in most cases.
