Wireless-AC 8260 Disconnects Sproadically

CMack · ‎07-10-2018

Hi,

We have multiple Lenovo and Dell Laptops that are running Intel(R) Dual Band Wireless-AC 8260 with Windows 10

Our APs are Cisco Aironet 1602i

I'm running driver version 20.60.0.7 but we have previously been running older drivers.

We have been experiencing issues with the Wifi Dropping for around 5-6 pings, during this period we would be disconnected from any Remote desktop sessions and Citrix windows would crash and Skype for business will disconnect. Cisco have looked at the issue and can see that the machine although is static will roam between 2 APs, the majority of the time you can see that this successfully reassociates. They have confirmed that the machine its deciding when to re-associate. Sometimes the failure can occur and the machine will reconnect to the same controller.

There is an entry in the event logs for:6105 - deauth after EAPOL key exchange sequence

We have had this issue with Windows 8 aswell however, it was was no where near as often as with Windows 10 and was generally accepted. However now it is happening 3-4 times a day per laptop and is becoming a huge issue.

We have setup a old Windows 7 machine laptop which has a completely different WLAN card. We are waiting to see if the issue occurs, I'm confident taht the issue lies with the 8260 cards.

Has anyone else experienced this issue?

Hi chris.mackenzie01,

We understand that you're having an issue where multiple Dell* and Lenovo* laptops that use our Intel® Dual Band Wireless-AC 8260 adapter are giving you disconnects during the day, we'll be glad to assist you.

In this case since you're already using the latest generic driver from our end, we can suggest the following:

- Perform a https://www.intel.com/content/www/us/en/support/articles/000022173/network-and-i-o/wireless-networking.html clean install of the wireless drivers again.

- In case the disconnects persists, you can repeat the same steps and install our https://downloadcenter.intel.com/download/27852 IT admin standalone drivers, these come as drivers only and don't come with the PRO/Set software tools. The file name for the driver only package is called WiFi_20.60.0_Driver64_Win10.zip

Let us know how the laptops respond after this steps.

Regards,

Drivers have been clean installed before. So I will try the standalone drivers.

Is there somewhere we can get old drivers? Archive for verison 19 drivers to try them?

Hi chris.mackenzie01,

Thank you for the update, sure, feel free to test the standalone drivers and let us know how the systems respond. As for getting and older version of our drivers, the oldest version I found currently on our download center is version https://downloadcenter.intel.com/download/27309/Wireless-Intel-PROSet-Wireless-Software-and-Drivers-for-Windows-10 20.10.2 in case you want to also test using this driver package.

We'll be looking forward to your reply.

Regards,

Leonardo

Downgrading drivers is a temporary solution at best. What are next steps to begin a permanent solution?

Hi chris.mackenzie01,

We're following up on your thread, let us know if you were able to test the standalone drivers on the system to see if the disconnects stopped.

Sorry for the delayed reply.

That driver has the same issue we were originally running on before we upgraded to hope to resolve the problem.

We have tried replacing the AP's to more powerful / newer models and it has not resolved the problem.

Thanks

Hello chris.mackenzie01,

Thanks for the update, in order to check further on this, we will need to perform again a https://www.intel.com/content/www/us/en/support/articles/000022173/network-and-i-o/wireless-networking.html Clean Installation of Wireless Drivers, using https://www.intel.com/content/www/us/en/support/articles/000022173/network-and-i-o/wireless-networking.html Intel® PROSet/Wireless Software and Drivers for Windows® 10 version 20.60.0. We need to have the latest driver before trying other actions.

If the issue persists, please provide the following information:

- Download https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- Intel® System Support Utility for Windows* and use it to Create a log; Scan your system with "Everything" selected, click "Next", then "Save" the output to a file. After that you can attach the file to your thread using the Advanced editor options.

- Is the issue still ocurring with latest driver in Windows* 8.1 and 7?
