We are currently having a weird issue with a ZEBRA QLN420 printer trying to acces Wireless Network. For some weird reason, we are getting authenthication issues when the printers try to connect ot APs model AIR-AP1852I-E-K9 as you can see in the attached image.
On the other hand, the authethincation works well when printers try to connect first time to APs model AIR-AP1852E-E-K9.
The weirdest thing is that when printers are correctly connected to an AIR-AP1852E-E-K9 AP, they are able to roaming to AIR-AP1852I-E-K9 AP :-s.
Any idea?. Thank you very much.
- For the problem case , perhaps the Wireless Debug Analyzer can help :
Which code version are you using?
There´s some bug related to Zebra:
But, as the message says that client is not responding with M2, this may be a client issue and not Access Point issue.
I´d talk with Zebra guys to see what can be done!

Thank you for your answers.
The WLC version is: 220.127.116.11 (so I think it is not affected by the bug CSCvp21915).
I have figured out that if I set the Fast Transition as Adaptive in the WLAN, it works correctly. Problem is that I cannot check the FT PSK box which I use for other clients if I select the adaptive option.
I am thinking that this is 100% a client issue but I find weird that it just happens for APs AIR-AP1852I and not for AIR-AP1852E.
