Wireless Adapter 8265 will not connect to certificate based wireless

[KCox1]

I have updated the drivers. I have completely uninstalled and reinstalled the device and drivers. I have tried OEM driver and Intel IT driver. Each time I try to connect to my enterprise wireless the device quits working and the event says that "WLAN Extensibility Module has stopped".

I have 30 other machines in the office that can connect without issue.

If i connect to our guest wifi which is just WPA2 passphrase everything works fine.

i was able to perform a clean install of the wireless driver and the issue persists. I've tried multiple different driver versions. I've tried the driver alone. I've tried the intel proset software. All roads lead to the device stopping when trying to connect to a certificate based wireless authentication network.

It may be an Internet issue. So, I will suggest you update the system and reset it. You may also check https://linksysroutersupportnumber.com/how-to-reset-recover-change-linksys-router-password-or-login/ to consult for how to reset linksys router and reset the router if you need any support regarding the Internet.

It's not an internet issue. We have 30 other workstations in the office (Mac and Windows) that all work fine. Also its Cisco WLC not a linksys router.

Hello KCox1, The issue you are describing seems to be related to the security implemented on the Enterprise Network. For example, a certificate is missing or the device is not authenticated. A. Have you checked the authentication deployed on the network? If a change on the wireless security occurred, you may not be able to connect to the network. B. Are other devices with an Intel® Dual Band Wireless-AC 8265 able to connect to the Enterprise Network? Wanner G. Intel Customer Support Technician Under Contract to Intel Corporation
