TitleContinual reauthentications from end devices with Qualcomm driver qca61x4a 12.0.0.720 and Windows 10 version 1809 - This is happening mostly with 802.1X WLANs, but can happen with WPA-PSK WLANs.
Symptoms
Continual reauthentications from end devices with Qualcomm driver qca61x4a 12.0.0.720 and Windows 10 version 1809. This is happening mostly with 802.1X WLANs, but can happen with WPA-PSK WLANs.
Environment
  • ExtremeWireless appliances
  • ExtremeWireless Access Points.
  • Firmware 10.41.13.0008
  • Clients end devices with Qualcomm NIC driver version qca61x4a 12.0.0.720.
  • Windows 10 version 1809.
  • WLAN configured with 11R (Fast Transition) and MFP (Management Frame Protection) enabled.
Cause
The Qualcomm NIC is sending a reply EAP packet (reply #3), that is not accepted by the Access Point, and consequently the packet is dropped, and the user has to start the authentication process again.
Resolution
  • The original resolution was with the new Microsoft OS version 19v1, but early testing with this OS has proven that the issue still exists.
  • The workaround is to disable 11R (Fast Transition) and MFP (Management Frame Protection).
Additional notes
To date, even the upgrade to 10.41.14.0009 has not had resolved the issue.
