Intel AC-8260 Causing CPU to hit 100% usage all the time

Hello, ever since I have replaced my laptop's wifi card with Intel AC-8260. It has been causing its CPU, specifically the first core to run at 100% usage at all times. Drivers have been updated to latest version, but it was to no avail, as the issue hasn't been resolved.

What can I do to fix this? Thank you!
