MR46 fail connection - authentication stage - new to Meraki

[A4WanMan]

I have a user reporting a PC is "loosing connection to the wifi throughout the day".  Checking the AP, I see a failed connection in the event log during the authentication stage with the reason:

reason='eapol_timeout' radio='0' vap='0' channel='11' rssi='62'

This is an HP mini PC using a USB wireless adapter (AC) with a Realtek driver.  The PC is in the same classroom as the MR46.  We have the same PC / AP combination in about 15 classrooms.

I have:

*  swapped the USB wireless adapter between another PC that isn't having reported issues

*  updated driver via Windows update

I updated the MR46 firmware to  27.7.1 today to see if that will help.  Issue stays with PC.  Other than re-imaging the PC, what are some other suggestions?

EAPoL timeout indicates an 802.1X issue. Have you checked the logs for this user on your RADIUS server?

Not using a RADIUS server.  Win 10 "desktop" PCs that we added a USB wireless adapter then connected to a WPA2 SSID manually.

I am also having this connection loss issue, also new to Meraki, and also not using a RADIUS server.  Looking forward to anyone else having some insight.

I may have solved my problem.  I changed the driver from the built-in Microsoft driver to the Realtek driver.  I also disabled the 2.4 Ghz band on the NIC since the AP is physically in the same room at the PC.  I have not had any more reports with dropping.  I think the NIC was jumping APs.
