Issues with both 8260, 8265 drivers after 19.0.1 for radius EAP-TLS

[PBjör]

Hello we have a strange issue which is reoccuring on all HP elitebooks using 8260 and 8265 networks. All drivers after 19.0.1 will fail getting internet access when connected To windows 2012R2 fully updated NPS using certificate (eap-tls)

When we however install a wifi driver earlier or at the level of 19.0.1 it works flawless. For 8260 we have tried 18.40 and it works great and for 8265 we tried the first driver 19.0.1 and it worked great.

All clients no matter the version will be able to connect and authorize radius, they will all get a valid ip adress and dns servers aswell as default gateway but after that the "new" drivers will stop working. Almost like they are missing a route or something.

The network for the Client will not work although the wifi still reports connected , working. on the newer drivers

The solution with using older drivers has worked on 3 of 3 clients all with similar issues so this IS an issue with the intel driver. Windows 10 version has ranged from the newest to 16xx versions, it doesn´t seem to matter

Anything previously reported? any solution to this issue?

Correction, the 8260 driver model is 18.33, 18.40 works sporadically (much better than the new drivers that doesn´t work at all but 18.33 works all the time, flawless)

All drivers works on wpa2-psk so this is only related to eap-tls

Hello perB,

As we understand, your systems are not able to connect to the wireless network using Radius EAP-TLS authentication when they have drivers newer than 19.0.1. We haven't had any similar reports, so we would like to check a few items first:- Are you performing a driver update, or a initial system installation? If possible, try 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 the https://downloadcenter.intel.com/download/27849/Wireless-Intel-PROSet-Wireless-Software-and-Drivers-for-Windows-10?product=94150 Intel® PROSet/Wireless Software and Drivers for Windows® 10 version 20.60.0.- Have you tried recreating the wireless profiles from scratch? You can import and configure the profiles to use EAP-TLS using the tools embedded in the OS, such as Windows* wireless configuration utility.Please let us know if there is any improvement after the clean driver install and recreating the wireless profile.Regards,Jonathan B.

I have both tried to completely reinstall a computer using a stock win10 1803 image. and the proceed with clean install of 20.60 and it doesn´t work. For the network interface 8265 only the 19.0.1 driver seem to work. Which is the first released driver

For 8260 we had complete success on bothe elitebook 820 G3 and HP revolve using driver 18.33. Nothing else works, 18.40 works sporadically but everything later doesn´t

WIFI profile is the same for all computers tested.

All older computers we have in the company seem to work fine aswell, probably cause they have older drivers

Shortly after that log was taken i switched to driver 18.33.0.1 and it worked perfect again. The log I posted is taken with your newest driver which you linked, it worked sporadically. Really strange behaviour. Some times it connected to internet after 15 ping drops but mostly not at all.

The old driver is consistent in that it always work. For ordinary wireless networks like wpa2 all drivers work fine, its only when using ad authentication and cert validation. All clients do get validatet using the radius no matter the driver, all clients get an IP from dhcp no matter the driver. But then, its up to the network driver and newer drivers just doesn´t work consistently

Hello perB,

We are still gathering some information to continue troubleshooting these issues. Please provide the following information:1. Are the clients able to get a valid IP address if you use newer driver versions such as 20.70.0.5?2. If so, can the client ping the AP or access to the local network?Wanner G.Intel Customer Support TechnicianUnder Contract to Intel Corporation

Hello

1. Yes they get a valid DHCP adress

2. No they cannot access anything and as soon as i uninstall the drivers and install the old ones they work immediateley. It is the same behaviour on all clients we have seen with some particular intel NICS mentioned earlier

Older NiCS usually work well with whatever driver still available.
