WLC 9800 issues with projectors

[hfaisca]

Hello,

I'm having some issues of comunication with a WLC 9800 and Projectors from Epson brand (Epson 955w), this projects are trying to reauthenticate in every 10 minutes and sometimes this equipment disconect completly.

I tried the following:

- Disable FT from ssid.

- Increase the session timeout to 86400 sec.

- Since this project conect with a usb antenna via wifi, i confirmed if 803.11b/g/n are enabled. the data rate 11mbps are mandatory and data rates bellow.

I will attach the logs from two device to this topic.

This is the log i got when completly disconnected.

Controller initiated client deletion with code: CO_CLIENT_DELETE_REASON_IPLEARN_CONNECT_TIMEOUT. Explanation: Controller did not learn client IP address in the allowed time. Actions: Check DHCP server and client IP configuration. Validate if DHCP required is set and client is performing DHCP negotiation. If all is correct, collect RA traces and EPC

  - Have an overall checkup of the controller configuration with the CLI command show tech wireless ; feed the output into :
                                    https://cway.cisco.com/wireless-config-analyzer/

    Check  the current software version on the 9800 controller , correlate this with :

I do not care what Epson says but all data rates must be enabled and must be set to "default" values.
