Boost Internet Speed with Command Prompt: 5 Effective Methods

Slow internet speed is a common problem that can be frustrating for internet users. Whether it’s due to network settings, PC issues, or ISP problems, it’s important to find a solution. Luckily, you can use the Windows command prompt to fix many DNS, TCP, and IP address problems that may be causing your internet to slow down. Here are 5 effective ways to boost internet speed using command prompt:

1. Renew the IP address

If you’re experiencing slow internet speed, it may be due to an IP conflict or an issue with the DHCP server. To fix this, open the command prompt with administrator rights and enter the following commands:

  1. Type ipconfig /release and press Enter.
  2. Type ipconfig /renew and press Enter.

2. Flush the DNS resolver cache

Your PC maintains a DNS resolver cache, which stores host names and IP addresses of websites you’ve visited. If this cache becomes corrupted, it can slow down your browsing speed. To fix this, enter the command ipconfig /flushdns in the command prompt and press Enter.

3. Reset Winsock

Corruption in the network sockets or infected LSPs can cause a slow internet connection. To reset the Windows network sockets, enter the command netsh winsock reset in the command prompt and press Enter. Remember to restart your PC for the changes to take effect.

4. Use the Netsh command

The Netsh command allows you to configure various network settings that can improve your internet speed. Try entering the following commands in the command prompt:

  • netsh int tcp set global chimney=enabled
  • netsh int tcp set global autotuninglevel=normal
  • netsh int tcp set supplemental
  • netsh int tcp set global dca=enabled
  • netsh int tcp set global netdma=enabled
  • netsh int tcp set global ecncapability=enabled
  • netsh int tcp set global congestionprovider=ctcp (for Windows 7 users)

5. Accelerate transmission

If your internet speed is slow only when streaming videos, your ISP may be throttling your connection. You can prevent this by entering the command netsh advfirewall firewall add rule name="StopThrottling" dir=in action=block remoteip=, enable=yes in the command prompt.

By following these command prompt methods, you can significantly improve your internet speed. Give them a try and see the difference!
