Windows XP, Windows Vista & Windows 7 - Quick Fix For Networking Problems

I've posted on "How To Repair/Fix Slow Internet Connection Issue On Windows XP & Vista" using ICR earlier, but unfortunately PCLive (the company of ICR) will cost you some payment to fix the internet problems on your computer. They play some tricks here (I thought it was a free troubleshooting/repairing because the software is freeware), I'm sorry for that for not testing the software first before posting it here.

So, we left that software aside and here's how to quick fix networking/internet problems manually using a few commands in your computer.

If you've lost or having a slow internet connections due to virus attacks (clean it up first before proceed this) or after you've doing a wrong internet tweaks or also after using some internet tweaking softwares, use this document to repair. These commands reset TCP/IP, Windows Socket, and Windows Firewall.

For Windows XP

1. Open a command prompt by clicking on Start -> Programs -> Accessories -> Command Prompt
2. Type the following commands, pressing Enter after each command:

• netsh int ip reset reset.txt
• netsh winsock reset
• netsh firewall reset

NOTE - Windows XP must have Service Pack 2 (SP2) installed in order for these 3 commands to work properly. Otherwise, only the first command will work.
3. Restart the computer.

For Windows Vista and Windows 7

1. Open a command prompt as Administrator by clicking on Start -> All Programs -> Accessories -> right-click on Command Prompt -> choose "Run as administrator"
2. Type the following commands, pressing Enter after each command:

• netsh int ip reset reset.txt
• netsh winsock reset
• netsh firewall reset

3. Restart the computer.

Summary

If the commands are typed in properly but errors occur, Windows networking may be heavily damaged. In addition, if these commands do not return errors, yet do not fix the Internet connection after the computer has been restarted, consider further troubleshooting:

• Power-cycle any external networking devices, i.e. routers, cable modems, DSL gateways, etc.
• Check Device Manager for any problems with Network adapters, i.e. if they are disabled or if drivers are not properly installed.

That's it.
