To resolve slow internet issues on your computer or laptop, you can follow these detailed steps, including commands and actions, to help improve your internet speed:

  1. Check Internet Speed:
    • Visit a reliable speed testing website (e.g., speedtest.net) and perform a speed test to determine your current internet speed. Note down the download and upload speeds for reference.
  2. Restart Your Computer:
    • Start by restarting your computer or laptop. This can clear temporary files and refresh network settings.
  3. Disable Background Applications:
    • Close any unnecessary applications running in the background that may be consuming bandwidth or system resources. This includes file-sharing applications, cloud syncing services, and software updaters.
  4. Update Network Drivers:
    • Open the Device Manager (Press Windows Key + X, then select Device Manager) and expand the Network Adapters section. Right-click on your network adapter and choose “Update driver.” Follow the on-screen instructions to update the driver to the latest version.
  5. Flush DNS Cache:
    • Open the Command Prompt as an administrator (Press Windows Key + X, then select Command Prompt (Admin) or Windows PowerShell (Admin)). Type the following command and press Enter: ipconfig /flushdns. This clears the DNS cache, which can help with resolving domain names faster.
  6. Reset TCP/IP Stack:
    • In the Command Prompt (admin), enter the following commands one by one, pressing Enter after each command:
      • netsh int ip reset
      • netsh winsock reset
      • Restart your computer after executing these commands. This resets the TCP/IP stack and can resolve network-related issues.
  7. Disable Auto-Tuning:
    • In the Command Prompt (admin), enter the following command and press Enter: netsh int tcp set global autotuninglevel=disabled. Auto-tuning is a feature that optimizes TCP/IP performance, but it can sometimes cause issues. Disabling it can help improve network performance.
  8. Change DNS Servers:
    • Open the Network Connections settings on your computer or laptop.
    • Right-click on your network adapter and select Properties.
    • Select “Internet Protocol Version 4 (TCP/IPv4)” and click on Properties.
    • Choose “Use the following DNS server addresses” and enter the IP addresses of reliable DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220).
    • Click OK to save the changes.
  9. Disable Large Send Offload (LSO):
    • Open the Device Manager (Press Windows Key + X, then select Device Manager).
    • Expand the Network Adapters section, right-click on your network adapter, and choose Properties.
    • Go to the Advanced tab and locate the “Large Send Offload” or “LSO” option.
    • Set it to Disabled and click OK.
  10. Check for Malware or Adware:
    • Run a full system scan using reliable antivirus software to check for any malware or adware that may be affecting your internet speed.
  11. Contact Your Internet Service Provider (ISP):
    • If the issue persists, despite following the above steps, contact your ISP’s customer support. They can check the connection from their end and help troubleshoot further if needed.

Remember, these steps are general guidelines, and the specific commands and settings may vary based on your operating system and network adapter. It’s also a good idea to consult with your ISP or a professional if you encounter any difficulties or if the slow internet issue persists.
