The QCA9377  with latest driver cannot associate with my access point with 802.11r enabled (works when 802.11r is disabled). The wireless capture shows that the authentication with the radius server went through successfully, but it fails at the message 2 of the 4-way handshake. The Access point complains that the MIC of in the message 2 from the wireless client is not matching the calculated value from the access point. With the same setup, iphone, ipad, and windows 10 laptop with intel wireless AC8260 works. Can someone look into this please. I have wireless capture of working (ipad etc) and failure cases (qcom wireless) and like to discuss the MIC calculation in detail. We've notice this on various types of cards that uses qcom wireless chipset (e.g killer wireless) with the same error. Thanks.
