In regards to the driver installed, some versions of the Intel® Dual Band Wireless-AC 7265 use 22.214.171.124, it will depend on the revision that was used in your PC by the Computer Manufacturer. You will have the latest drivers as long as you use the most recent version of Intel® PROSet/Wireless Software and Drivers for Windows® 10*.
Regarding the slow speed, here are a few items for your consideration:
- The Computer Manufacturer Support is always the best source to obtain drivers. As noted in our download center:
"The driver or software for your Intel® component might have been changed or replaced by the computer manufacturer. We recommend you work with your computer manufacturer before installing our driver so you don’t lose features or customizations."
- Any of the three driver versions are valid options (OEM, Inbox, Generic), in some scenarios one may work better than other. If HP does not have a driver available and the generic one from Intel® Download Center does not work well, then we advise you to use the Inbox driver from Windows*.
As additional information, we've had a few reports from other users regarding low speeds or errors after Windows* 10 RS2 update, this happens with some Intel® Wireless Adapters as well as adapters from other Manufacturers. For this type of cases, we advise to perform the workarounds mentioned in the following Microsoft* forum: WiFi issues with Creators Update.
The workarounds mentioned are using the inbox drivers, disabling RSC, or changing the MTU size. Please check the thread for more information.

it seems that the latest fix from Microsoft (KB4022716) has fixed the problem. It talks about the RSC problem & a fix for it.
I have reinstalled the latest Intel WiFi software and performance is back to what I used to have.
Thanks for clarification over the driver version. Maybe you should update your documentation for this device since it is confusing, making me think the problem was because the wrong driver was installed.
We are glad to know that the issue has been resolved, we've had some reports to inform that this Windows* update actually helps with this type of wireless issues. We are sure this will be a great reference for other users as well.
