HP Zbook 17 G5

• Is the Intel® Wireless-AC 9560 the one that came pre-installed on the system?

Yes

20.90.0.7 and older work properly

• Are you having any error message on the system at the time of enabling the Windows® mobile hotspot? If you do please provide me with a picture of the error.

Yes i do, will provide in my next reply

• Have you completed a wireless driver clean installation? (See the steps below).

Yes but will do it again to give you a detail log because i am a proficient user and while i know the new drivers are broken i know you won't fix it unless i give you this info

Here is log for the working drivers:

Here is log for the bad drivers. Also worth noting that after i did a clean install (with deleting the previous configuration) of the new drivers the problems are worst. There is difficulty connecting to the network, adapter seems to reset every 5s. Will try to update over the old working drivers to see if i can get them to work like before to show you the other error. Rolling back to the old drivers everything is working perfectly. Your new drivers are completely broken.

Hello Leonardo.

I can confirm the hotspot issue at least has been resolved successfully with the latest 20.100.3 updates that came out 3 days ago. Thanks for notifying me to their release. I cannot confirm that everything else works smoothly though since i've just installed them, but assume if i don't reply back the drivers are working normally.
