Hello, I'd like to help you resolve this issue.
From what I've been able to find, it seems to me that this NETwNs64.sys
file is indeed a driver for the built-in WiFi adapter of your laptop. However, a version of Norton AntiVirus
installs a system file with the same name and extension. Most users have a pre-installed trial version of Norton that they never use, so the adapter could be mistaking the Norton .sys file as the driver and crashing every time.Only
if you have Norton AntiVirus installed, thoroughly uninstalling it and reinstalling the WiFi driver afterward can fix your problem. If you don't
have Norton installed, disregard this answer.
Follow these steps if you don't mind uninstalling Norton:
1. Uninstall Norton via the Control Panel
2. After uninstalling, run CCleaner to clean temporary files and fix registry errors. You can get a portable version (run the .exe inside, no installing) here
3. Reinstall or update the WiFi adapter driver with Device Manager or Windows Update
I hope this helps resolve your issue. If not, I'll continue to provide assistance to the best of my ability.
