Hi ,
This isn't the driver, but rather the control software. Access Device Manager. Check if you're using the same version as your laptop model. Go to Device Manager > Network Adapters > Killer > Properties > Details. Check if it's the same version.
If so, install this app from the Microsoft Store.

If you have any questions, take a screenshot and post it here from Device Manager.
What is your laptop or desktop model?
Give feedback if the information was useful or not.
Thanks
