Intel 9560 wifi connection slow/non-functioning

[dwalleck]

A few months back I noticed that no matter how strong my wifi signal was, I was getting slow (less than 1MB/s) speeds when using the wifi on my ZBook X360. After troubleshooting for awhile, I found endless streams of this series of errors in the Windows Event Log:

• The network interface "Intel(R) Wireless-AC 9560" has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets. Reason: The network driver requested that it be reset. This network interface has reset X time(s) since it was last initialized.
• Intel(R) Wireless-AC 9560 : Could not find a network adapter.
• Intel(R) Wireless-AC 9560 : Has determined that the network adapter is not functioning properly.
• Intel(R) Wireless-AC 9560 : Has encountered an internal error and has failed.

Uninstalling and re-installing the driver for the wifi card has not fixed the problem. I've tried both the driver version that HP provides (20.90.0.7) and the latest from Intel with the same result. I really want to believe that I have a faulty wifi card, but when I reset Windows 10 completely, it does seem to work for about a day before begining to fail again. I don't upgrade any other drivers or Windows in that time period, so I'm not sure what the trigger is for it breaking again. This is some of the strangest behavior I've ever seen. Any suggestions would be appreciated.

So that may be the answer, original install and old drivers.  1 day later updates have happened.

Note the driver version that is in the original install and rollback?

I've re-installed Windows due to other issues and stuck with the original driver and so far it's been okay. What doesn't make sense is why the driver that HP offers as the current one for this laptop would be one that's not compatable. I'm having other issues so I'm still a bit worried I'm having some other kind of hardware failure, but I'll keep my fingers crossed.
