so I bought a few 1142's and converted to Autonomous. when connected I pull a file from my smb server and get 100-108mbps throughput. coming from my apple n router (450mbps) I can pull greater than 220mbps.
I understand the 1142 is only 300, I should be able to get ~145mbps real world. I mention the apple speeds to prove that my server is capable of pushing the file. Lan I get close to full gig speeds from the server as well.
I have tried everything (I think) including no encryption, every N channel etc., am I missing something?
here is my config:

I presume the "horrible speed" was observed with 802.11b radio and NOT 802.11a radio?
12-27-2016 04:08 PM
this is on do1. Mac shows I'm connected as N client at 40 MHz. both radios should have b disabled. do1 should be N only right? and I have tried with do0 both enabled/disabled
12-27-2016 07:02 PM
Just to get things straight, do the following:
1. Disable 802.11b radio;
2. On the 802.11a radio settings, disable data rates from 1 Mbps to 11 Mbps. Make 12 Mbps as Mandatory and all the rest is Supported.
Try that and see if it improves things.
12-28-2016 06:07 AM
unless I'm missing something isn't that how the speed settings for both radios are set up, or is there something else I need to do?

On the 802.11a radio settings, disable data rates from 1 Mbps to 11 Mbps. Make 12 Mbps as Mandatory and all the rest is Supported.
This forces wireless clients to operate at HIGHER SPEED.

I got what your saying. isn't the following configs doing just that? on 2.4 do0 I'm trying to allow g/n. on 5g do1, I just want N

If you are right next to the AP whole testing and you are connected at a high rate, then there is not much else you can do. I have never really compared speeds with different vendors, maybe with Cisco, Meraki and Aruba, but at the end of the day as long as it was stable and they did have good throughput, no one really cared. When you take a home wireless AP/router, they will add their own flavor of "turbo" that works well with some end devices but maybe specific to their own devices. Enterprise vendors follow a standard which doesn't use these vendor specific features.
The only other thing to try is use a different code and see that that helps or not. Your config is fine and as long as your connected to 5ghz, you will get better throughout than 2.4ghz.

well, I got it going. looks like my AP's (all 3) do not like the 15.3 code. I tried a few versions and all had the same issue. I went down to the 12.4 and bang! 130+ mbps. I'm gonna do some side testing with my 3rd ap with 15.2 code and keep the other 2 operational as is. but so far so good.
only difference I can see is the connection is sporadic on this code. ill hit, for ex., 120 then it drops to 65, back up to 110 etc. on the 15.3 code it was a steady 100-103 mbps.
12-28-2016 02:46 PM
on 2.4 do0 I'm trying to allow g/n.
Cisco 2.4 Ghz does NOT support 802.11n because channel-bonding two (out of three) non-overlapping channels is just plain stupid. Other vendors can/may do it but Cisco has put a stop to this.
I got what your saying. isn't the following configs doing just that?
The reason why I'm recommending with 5.0 Ghz is because there are more channels to play with compared to 2.4 Ghz. If your wireless clients can get a higher speed at 5.0 Ghz then it only means that the 2.4 Ghz channel in the area is very crowded.
