allIsolate wireless networks from critical systems using VLANs or firewalls.
🧯 If You Can't Patch
- Implement strict wireless network access controls and monitoring
- Deploy network intrusion detection systems to monitor for WiFi disruption attempts
🔍 How to Verify
Check if Vulnerable:
Check driver version in Device Manager under Network adapters > Intel(R) Wireless adapter > Driver tab. Version should be 23.100 or higher.
Check Version:
wmic path win32_pnpsigneddriver where "devicename like '%Intel%Wireless%'" get devicename, driverversion
Verify Fix Applied:
Verify driver version shows 23.100 or later in Device Manager and WiFi connectivity functions normally.
