I have 4404 WLC's running 22.214.171.124 and I am getting invalid MIC errors with new Zebra QL220 Plus printers using wpa/peap/tkip. All other clients work fine, just not these printers.
[SECURITY]1x_eapkey.c 723: Received EAPOL-key M2 with invalid MIC from cckm mobile MAC ADDRESS
[SECURITY]1x_ptsm.c 391: MAX EAPOL-KEY M1 retransmissions reached for mobile MAC ADDRESS
According to Zebra's kb, changing the following settings is all that is required to get the printers to work. I did not have the same luck.
config advanced eap identity-request timeout 5
config advanced eap request-timout 5
The printers are running the latest software SHSTG10Z.
Any help is appreciated.
