Hello,
Thanks for posting in the Microsoft Community.
I understand you're experiencing a network connection issue after updating to Windows 11 version 24H2, specifically encountering Error Code: 0x800704f8. You've already attempted changes via Group Policy and Local Security Policy, but the issue persists.
Here are some troubleshooting steps you can try:
Reset Network Settings
This is often the most effective fix:
- Open Settings → Network & Internet → Advanced network settings.
- Click Network reset.
- Restart your PC.
Reinstall or Update Network Drivers
- Press
Win + X → Device Manager.
- Expand Network adapters.
- Right-click your adapter → Uninstall device.
- Restart your PC to reinstall automatically, or download the latest driver from the manufacturer’s website.
Set Static IP and DNS
Since DHCP may be broken in 24H2
- Go to Control Panel → Network and Sharing Center → Change adapter settings.
- Right-click your network → Properties.
- Select Internet Protocol Version 4 (TCP/IPv4) → Properties.
- Set:
- IP address: e.g.,
192.168.1.100
- Subnet mask:
255.255.255.0
- Default gateway:
192.168.1.1
- Preferred DNS:
8.8.8.8
- Alternate DNS:
1.1.1.1
Group Policy & Local Security Policy Fix
If you’ve already tried this, double-check these settings.
Use Windows Troubleshooter
- Go to Settings → System → Troubleshoot → Other troubleshooters.
- Run Network Adapter and Internet Connections troubleshooters.
Roll Back the Update
- If none of the above work, consider uninstalling the 24H2 update via Settings → Windows Update → Update history → Uninstall updates
If you need help with any of these steps or the issue still persist, feel free to ask
