1. Go to Settings > Network & internet > Wi-Fi (or Ethernet if you're using a wired connection).
2. Click on your connected network.
3. Make sure the Metered connection option is turned off.

8. Scan for Malware

Run a full system scan with your antivirus software to check for malware that might be interfering with your internet connection. Windows Defender, included with Windows 11, is a good option, or you can use third-party antivirus programs like Bitdefender or Norton.

9. Check Your Internet Speed

Visit a website like Speedtest.net to check your actual internet speed. Compare the results with the speed you're paying for from your internet service provider (ISP). If there's a significant difference, contact your ISP to inquire about the issue.
