i have A620 controller ( version 220.127.116.11) with 2 AP93 configured on it with WPA2 enterprise (AES) authentication.
APs are setup as
Name ▲ AP Group ▲ Status ▲ AP IP ▼Outer AP IP AP Type Switch IP .bg Clients .bg Channel .bg HT Mode .a Clients .a Channel .a HT Mode IPSEC Actions
correct me if i am wrong please , alot of noice on floor is it thats why poor signal quality and speed?
i have already A200 controller with 2 AP running on it (old wifi network) i was just testing it out how it goes, would try to turn off old wifi on weekend and see the results on noise levels and signal power
To Client (bps)
From Client (bps)
My main problem is that sitting users close to AP2 they are still connecting to AP1 with very low signal quality and speed of 1mbps and wont connect to AP2 which is like 10 feet away ?
can any body please guide me through how to sort this issue so i can do some testing on weekend?

What is the reason that you are using channel 4 and channel 8?
For the noise floor you should check your environment with the spectrum monitoring feature if you have valid rfprotect license. You may also check what devices are possible causing the interference - this can be a microwave oven, cordless phone, bluetooth devices etc. and where the AP's are placed.
Btw. 10 feet does not seem to be too far, is this a test environment?
What kind of devices do have roaming issues?
The roaming is very client specific, however, you can set some parameters on the controller to provide better roaming.
you can set the "validate-pmkid" in the dot1x profile
you can also try "handoff-assist" in the rf profile or try to set the "local probe response treshold" in the advanced ssid profile.
You may find detailed explanation in the ArubaOS User Guide regarding these features.

Forgot to mention that you also need to make sure your client has up-to-date drivers. On some clients you can set the roaming aggressiveness (on Intel chipsets for example) you may check this, too.

Thank you for your valuble reply, it didnt specify any channel thats why AP was selecting any avaiable channels but i did made some changes, i have set APs on Channel 1 and max EIRP to 15 as i thought to check what allowed MAX EIRP for country code AE is .
show ap allowed-max-EIRP ap-name ap1 country-code AE
Channel 1 2 3 4 5 6 7 8 9 10 11 12 13 14 36 40 44 48 52 56 60 64 100 104 108 112 116 120 124 128 132 136 140 149 153 157 161 165

Handoff-assist is on and set to value 50
local prode response treshold is set to value 20
i couldnt find the validate-pmkid in dot1x profile if possible can you give me command or till then i will try to firgure out how to enable it.
first posit i mention i think the noise is too hight becasue of old A200 controller with two AP running and i can see them interfaring and showing those as roudge, which i can only turn off on week end only :( and run further tests which can i think resolve my signal issue ( please advice if iam correct)
i was testing romaing issue on updated new wireless cards and both of those laptop dont support 802.11K feature and will not connect to AP2 no matter how far and on low signal i get even it drop the signal out.
this is the problem as user is like 10 feet as you said is not too far should connect to AP2 (10 feet away) and is still connecting to AP1 and signal is very low.
i have the license for spectrum and i will try to do as you advised.

First of all I would suggest you to let ARM manage the channel and tx power settings at least while you are troubleshooting the roaming issues.
Validate PMKID can be found in All profiles - wireless lan - 802.1x authentication profile - choose the one which is assigned to your ap group and ssid - advanced tab (middle right section)
First try to enable only the local probe response treshold feature and disable handoff assist. If the local probe response treshold does not help you may try the handoff assist.
Also make sure the spectrum load balancing feature is disabled while local probe response treshold is enabled.
You may also try to disable the low data rates in the SSID profile.

i did as you advised, there was alot change in speed which was good, still client romaing didnt work.
i turn off the AP1 and let the Ap2 on and try to see if a client can even connect to it, client was able to connect
worst thing was that like 2 metters away i was connected with 2 bars and 300 mbps , if i go away like 5 meter gone cannot find the ssid ?
may be location issue so removed it from there plugged at the same spot where AP2 was same issue.
now what to do with this AP2 , shall i restore it to factory setting and re-set it up ?

What kind of devices are you using for testing?
You should try the roaming with different devices like iOS device, Android, Windows laptop etc. Do you have the same issue with all of these?
Have you tried to change the romaing aggressiveness on any of the clients?
When you are 5 meter away from the AP you can not even see the SSID on the client? This sounds strange.
If you want to reset the AP use the purgeenv command not the factory reset!

I used , Dell , IBM & HP laptop with required thing enabled on wireless card win xp and win 7,Iphone 5s , Samsung S2 , S3 HTC (all runing 4.0 andriod)
same having signal issue with AP2 (i have took off the AP1)
as for when all these devices connected to AP1 samsung devices were only who will drop out the connection while still connected to AP1 as for HTC and laptops they work all good and was not switching to AP 2 if near to AP2 and AP1 signal is low.
ok i will try purge AP2 and see if fix any issues on this and get back to you.
