Hello TJMcClintic,

We understand you would like more information regarding some warning events on Device Manager related to your Intel® Dual Band Wireless-AC 8265.

We can see that you're using 802.1x with PEAP on a WPA2-Enterprise network. In most cases it's normal to see deauthentication after EAP over LAN key exchange warnings as the adapters attempts to roam or renews it's authentication. The problem comes if these are frequent or if your system is entirely unable to authenticate causing a disconnection.

 

In order to better assist you we would like the following information:
  1. Do the errors result in loss of connectivity?
  2. What is your wireless router/access point brand and model?
  3. How long ago did the issue start?
  4. Please share your wireless Autoconfig report
    1. Right click your start menu icon and select Command Prompt (Admin) from the list.
    2. Enter: netsh wlan show wlanreport
    3. Go to C:\ProgramData\Microsoft\Windows\WlanReport\
    4. Upload the wlan-report-latest.html file along with your reply.

Also, there is a newer driver available. Is it possible for you to update to this driver and see if the issue persists?

  1. Do the errors result in loss of connectivity?
    1. This we are not sure as the log shows the error and Citrix seems to be impacted.
  2. What is your wireless router/access point brand and model?
    1. Aruba 335 with 7240 controller
  3. How long ago did the issue start?
    1. After upgrading to driver version 20.30.1
  4. Please share your wireless Autoconfig report
    1. Right click your start menu icon and select Command Prompt (Admin) from the list.
    2. Enter: netsh wlan show wlanreport
    3. Go to C:\ProgramData\Microsoft\Windows\WlanReport\
    4. Upload the wlan-report-latest.html file along with your reply.
      1. I would prefer to send direct as to not post the details of this host information. Is that possible?

We are having a similar issues that spans upwards of 2500 unique endpoints in our environment.

We essentially have 2500 Lenovo Endpoints with a variety of Intel Wireless Adapters DOS'ing our ISE and Active Directory infrastructure daily.

Same error in event log -

Warning Error in Event Log - deauth after EAPOL key exchange sequence

Were talking at times 30 to 50 thousand successful re-authentication requests (yes successful) from a single endpoint in a day multiplied 2500 endpoints.

So far we have seen the problem on the following wireless adapters 7260,8260, 8265, 7265 and Centrino 6205 and various driver versions:

18.33.9.3

20.30.0.7

19.50.1.6

20.50.2.1

19.50.1.6

20.50.1.1

15.18.0.1

19.51.12.3

15.16.0.2

Hi,

a little bit more info:

Also Lenovo T490 model seems to be affected, saw the same behavior today first time with two T490 laptops

* reboot does not help

* event viewer has events 6105 "deauth after EAPOL key exchange sequence", source netwtw08

* if you wait 20-30min, the laptop usually can connect without problems

affected driver version for T490 21.30.2.1

 

We have Ruckus wireless R500 APs with firmware version 200.7.10.202.94

 

Lenovo support has suggested turning on "Wireless auto disconnection" feature from bios, this did not help.

Try disabling 802.11r (Fast Transition). Our issue was solved when I disabled it from the WLAN we are using.
