Describe the bug

wlan0: disassociated from xx:xx:xx:xx:xx:xx (Reason: 252=)

A) need to improve the error messages.
B) need to let connman reconnect of 252 - 23

To Reproduce

Wait till session timeout of 86400 on Cisco 9130 access point

Informations

• LE Version: 11.x
• Hardware Platform: Tanix TX6 RTW88

Did you mixed up log link?

[heitbaum]

@jernejsk - no it’s the documentation of the logs from the Cisco WLC (or in my case the Embedded WIreless) - the logs from the TX6 are http://ix.io/40S7 . But will be the same in other devices.

Based on reading the blogs, ieee site …. It looks like an “undocumented” “unratified” Cisco standard. I have added the following kernel code. I’ll see if I get the right feedback. But I will want to / need to make an update to connman to try to reconnect On 252 - 23

Interesting. Do you plan to work with kernel/connman community to solve this?

[heitbaum]

Yes - plan on improving / understanding / fixing the interaction between connman/iwd/cisco/intel… The rtw88 (and the conman/iwd direction) gives some opportunity in this area.

I have a pair of 9130 APs at home in Embedded Wireless Controller mode (and at work where we have 1000+ APs) WiFi 6, along with EAP authentication (and Intel drivers) have been a challenging issue. Drivers have been getting better and firmware on both the WLC and EWC. We are still experiencing issues with MIMO power save mode / spatial multiplexing power save (SMPS) mode. Stability of RF/IoT Devices (mostly Android now) on Fast Transition Enabled/Adaptive networks also a black art.
