Hi nhật quang lê,
Thank you for sharing the details of your issue. Based on your description, the Event ID 1014 (DNS Client Events) indicates that Windows attempted to resolve a domain name but didn’t receive a timely response from any configured DNS servers. This often points to DNS resolution problems rather than a hardware failure.
The reasons for why it happens are usually:
- VTVCab’s DNS servers may be slow or unstable, especially under gaming traffic.
- Genshin Impact uses multiple servers; if DNS queries fail, the game can trigger network resets.
- Windows 11 24H2 has known networking-related bugs that can cause DNS timeouts.
Please try these steps out when you have the chance:
Flush DNS Cache
Open Command Prompt (Admin) and run:
ipconfig /flushdns
Change DNS Servers Switch to a reliable DNS provider:
- Google DNS:
8.8.8.8and8.8.4.4 - Cloudflare DNS:
1.1.1.1and1.0.0.1
Reference: Change DNS settings
Update Network Drivers
- Go to
Device Manager → Network Adapters → [Your Wi-Fi Adapter] → Update Driver. - For Intel or Realtek adapters, download the latest drivers from the manufacturer’s site.

Disable TCP Offload
Run in Command Prompt (Admin):
netsh int ip set global taskoffload=disabled
Optional: Adjust Wireless Mode
In Device Manager → Adapter Properties → Advanced, set Wireless Mode to a specific band (e.g., 802.11a) if disconnects persist.
Router & ISP Check
- Restart and update your router firmware.
- If the issue persists only on VTVCab, contact their support or try a VPN as a temporary workaround.
