datalogic joya a6 romaing disconnection

[silvio.compri80]

Dear Community,

I have a 2504 controller version 8.5.103 with AP1832i in local mode.

I find many problem with this kind of devices with Androis 7.1.2.

They disconnect frequently when they have to make roaming.

In the same environment all other devices works perfectly for data and voice (Ascom i62)

I attach debug client and show running config

Thank in advance

 - Have a go with the Wireless Debug Analyzer available from the link below; while you are at also checkout  your controller configuration with the Wireless Config Analyzer.

Dear Marce1000,

thank you for your reply.

This procedure is being already done.
Nothing to set about best practises or config error.

Plase le tme know if you can help me about this problem

[marce1000]

 Android 7.1.2 is getting old (is from 2016) check if your problem persists , with versions 9.x or 10.x. This could be done with a android test-device (for instance).

Hi Marce 1000,

I have no choise.
I MUST use this devices with Android 7.1.2.
Is anything that can I Do to solve this isssue? Any Cisco WLc version? Any Setttings?

[marce1000]

 - I understand the issue is in the Android-train, yet I would find this test useful, so that the problem is determined.

Hi marce,

We cannot upgrade the palmar becuse the software for warehouse run on this platform, I have already asked to the supplier and the supplier says this palmar run very well in other wireless platform ex: mikrotik and aruba.

Thank you

[patoberli]

Upgrade the WLC, you are running a VERY old and buggy release. I suggest upgrading to 8.5.161.0.

[silvio.compri80]

Thank you,

already done, nothing changed.

[patoberli]

Do you have enabled any of the fancy (and sometimes troublesome) features like 802.11k/r/v?

[silvio.compri80]

Hi patoberli,

Yes always disable r,k,v and assisted roaming.

Thank you for you reply

[patoberli]

Good, so all typical recommendations are done.
In this case I'd like to see a debug of a client roaming.
Can you run on the WLC a "debug client macaddress" and then roam the client.

What I have seen in this troubleshuting it is this kind of palmar have often High SNR value when they are close to the AP.

The higher the SNR the better. You typically want to be about 25 but not lower than 20.
