Hi,
I am working in an enterprise WLAN environment (Aruba AP-635, ArubaOS10, Aruba Central).
We are regularly seeing event logs in Aruba Central with the error 'De-authentication sent from client - unspecified failure'. When this is experienced the client is disconnected from the network, and in some cases, unable to join back for a period of time.
The client is a Windows 10 laptop using the Intel AC5960, driver release 23.90.0.2. On another machine, Windows 10 using the Intel AX201, driver release 23.90.0.2 we do not see this error.
The WLAN that the clients are connecting to are 5/6Ghz, running with 40Mhz wide channels. They are supporting 802.11a/b/g/n/ac/ax.
There is no pattern or event that occurs before this happens, it is simply random.
I have seen older posts from several years back, suggesting running 20Mhz wide channels, but this cannot be the fix for an 802.11ac adapter.
Are there any logs on the client I can check within the Event Viewer or elsewhere in the operating system?
We do not see the problem with Apple, Android or other Windows devices running different WLAN NICs.
Appreciate any support / advice that can be offered.
