Windows Vista Just installed Windows 7 now I can't access the internet

[kryzdafer]

I just installed windows 7 yesterday and the internet was working fine. I wake up and my system is restarted due to a update and now I can't access the internet on this computer. All of my other networked computers can access the internet, but this one can't. I went to troubleshoot internet connection and it says it can't contact the DNS server. I did a system restore on the update and still no luck. This is extremely frustrating!

It sounds like you're experiencing issues with your Windows 7 computer not being able to access the internet after a recent Windows update. The fact that other networked computers can access the internet suggests that the issue might be specific to the configuration on this particular computer. Here are some steps to troubleshoot and potentially resolve the issue:

Troubleshooting Steps:​

1. Verify Network Connection:
   • Ensure that the network cables are properly connected if you are using a wired connection. If you are on Wi-Fi, ensure that the Wi-Fi adapter is turned on.
   []Check DNS settings:
   • Since the troubleshooter mentioned a DNS server issue, check the DNS settings on your computer.
     • Go to Control Panel > Network and Sharing Center.
     • Click on your active network connection.
     • Click on Properties.
     • Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
     • Ensure that Obtain DNS server address automatically is selected. If it's not, you can set it to use your router's IP address as the DNS server (commonly 192.168.1.1 or similar).
   []Flush DNS:
   • Open the command prompt as an administrator and type the following command:

      ipconfig /flushdns

   []Reset TCP/IP:
   • In the command prompt, run the following commands:

      netsh int ip reset netsh winsock reset

   []Check Firewall and Antivirus:
   • Disable your firewall and antivirus temporarily to see if they are blocking the connection.
   []Check for Proxy Settings:
   • Ensure that there are no proxy settings configured that might be causing the connectivity issue.
   []Update Network Drivers:
   • Make sure your network adapter drivers are up to date. You can do this by going to Device Manager, finding your network adapter, right-clicking on it, and selecting Update Driver.
2. Restart Your Router:
   • Sometimes, restarting your router can resolve connectivity issues.

     Additional Tips:​

     • If the issue persists, you might consider performing a clean boot to see if any third-party applications are causing the problem.
     • You may also want to consider updating Windows 7 with the latest updates after resolving your current issue.
     Try these steps and see if they help resolve the connectivity issues on your Windows 7 computer. If the issue persists, feel free to provide more details for further assistance!
