I have a user I assigned a 20mbps traffic priority to that is doing speed tests at only 12mbps. When I remove the traffic priority, he can do speed tests at 50mbps. i have other users on other parts of the network that get what the traffic priority is set for with no problem. Can anyone explain why this may be happening? There are only TWO users on this new 1000 AP and the other user wasn't on during these tests. Not sure what I need to look at here to grasp what is going on. Thanks.
first, make sure there is no other traffic in the background that's causing the speed drop the customer is seeing. we observe that fairly frequently. watching the throughput chart on the tools page will show you real-time traffic flow.
2nd, check for pause frames in switch going up to the AP, you can get compounded speed issues from network congestion. check and see that you are getting the speed you expect to get on the network switch at the AP.
Since he gets 50mbps when the traffic control is turned off, he should get 20mbps with it on and not 12. The AP is pushing the bandwidth or else he wouldn't get the 50. It's the traffic priority control that is acting weird.
the traffic shaping on those radio work as intended, I have many hundreds of APs up and thousands of CPEs running without that issue. nearly every speed problem can be pointed towards a busy scheduler (not in your case) network congestion (possible) pausing issues (possible) or end user congestion, also possible.
if that AP is quite, and your running at good modulations, 50mbps is a little low speed for a 20mhz channel and very low for a 40mhz channel which to me would make me look into congestion related issue. because the symptoms show from setting QoS doesn't mean they are the reason, just amplify what is being observed.
can you tell us more about your setup, what switch, what backhaul or data source, and what end user equipment you are running and we can help further with narrowing down where to find the actual clog.

Are these speed tests being conducted to outside servers (speedtest.net, testmy.net, etc) via the customers router? Could be the customers router is bad, or interference to the router or device doing test if connected wireless.
If you connect directly to the SM via ethernet cable, what speeds to you see performing the same speed tests?
What throughput are you seeing under "Tools > Wireless Link Test?
The other customer on this AP, are they getting the throughput you have allotted them?

For us ^^^^^^^ is almost always the cause. The client is doing something else on their network without knowing it. Easily 80% of our ''slow'' support calls come from customer's whose bandwidth is being used up by them, and since they aren't aware of what their devices are doing on their network, they instead blame the internet.
So, in this client's situation... my first suspect would be that they are doing 8 Mbit of other/unknown/cloud stuff in the background - so that they are getting their 20 Mbit QOS, just that it's 12Mbit SpeedTest.net plus 8Mbit of iCloud or Windows10Updates or DropBox or Torrents or XBox Updates or any of the 1,000 other 'cloud' things that going on in the background these days.
Maybe not - maybe you've already watched their CPE's throughput chart and you can see it's at 0/0 before and after they do the speedtest. But if you haven't verified that, then that is always the first place I look, before looking further down the rabbit hole :)
