How to Fix: [Win 11] Unstable internet with CMD temporary fix
Fix unstable internet on Windows 11 with CMD by releasing and renewing IP addresses.
The issue you're experiencing with unstable internet on your Windows 11 system is likely due to a temporary fix recommended by your friend/co-worker, which involves running the commands `ipconfig /release` and `ipconfig /renew`. This method can help resolve connectivity issues caused by a misconfigured DNS cache or a failed DHCP lease renewal. However, it's essential to understand that this is only a temporary fix and may not address the underlying cause of your internet instability.
⚠️ Common Causes

- The on-board WiFi 6 adapter may be experiencing issues due to outdated drivers or hardware compatibility problems.
- Interference from other devices in your home network could be causing connectivity issues and reducing internet speeds.
