Problems with HP 560 AP and iPhone 12 Pro Max

[davidlan]

I have the following problem. Our first iphone 12 Pro max (IOS 14.6.3) is unable to do a successfull  4-Way EAPOL handshake, with our HP 560 AP (firmware 6.6.8.1-23399). The log shows "Received EAPOL key frame with a bad MIC result from client". The WLAN is configured with WPA2 personal (preshared key).

I already did a packet trace and the response frame (2nd frame in the handshake) of the iphone, which is not accepted by the AP,  loooks ok. But I have no means to verify the correctness of the MIC in the response.

With all laptops and other phones I have no problems in this place. Also this iphone works quite well in another location with an ARUBA 325 AP.

Are there any known problems in this configuration.

Has the preshared key any role in the calculation of the MIC. (because this is quite full of strange characters and symbols)

Hello @davidlan !

Seems your guess regarding special characters in the pre-shared key is right - https://community.hpe.com/t5/M-and-MSM-Series/Problems-with-HP-560-AP-and-iphone-x/td-p/7002840#.YO3keWQzZB9
