Solution Steps

  1. 1 First, check your network connection: Press Windows key + I, go to Network & Internet, and ensure you're connected. Try opening a website in your browser to confirm internet access. If you're on Wi-Fi, try moving closer to the router or restarting it.
  2. 2 Run the network troubleshooter: Settings → System → Troubleshoot → Other troubleshooters → Network Adapter → Run. This can automatically detect and fix common network issues.
  3. 3 Update your network adapter driver: Press Windows key + X and select 'Device Manager'. Expand 'Network adapters', right-click your adapter, and select 'Update driver'. Choose 'Search automatically for drivers'. If Windows doesn't find a new one, visit your PC manufacturer's website to download the latest driver. An outdated or corrupted driver can cause write faults.
  4. 4 Disable and re-enable the network adapter: In Device Manager, right-click your adapter and select 'Disable device'. Wait a few seconds, then right-click again and select 'Enable device'. This resets the adapter's state.
  5. 5 Check firewall settings: Temporarily disable Windows Defender Firewall (Control Panel → Windows Defender Firewall → Turn Windows Defender Firewall on or off → Turn off for both). Try the operation again. If it works, re-enable the firewall and add exceptions for the app you're using. Also check third-party security software.
  6. 6 If you're using a VPN, disconnect it and try again. VPNs can sometimes interfere with network writes.
  7. 7 Run a network reset: Settings → Network & Internet → Advanced network settings → Network reset → Reset now. This reinstalls network adapters and resets network components. You'll need to reconnect to Wi-Fi after.
