Windows 7 AGN 5100 Intel wifi issues

Troubleshooting Steps:​

1. Update Network Drivers:
   • Even though you've tried drivers from Intel, it's worth ensuring you have the latest drivers for your network adapter installed. You can try the following:
     • Go to the Device Manager (Win + X, then select Device Manager).
     • Locate your network adapter under "Network adapters," right-click on it, and select "Update driver."
     • Choose "Search automatically for updated driver software" to let Windows search for the latest driver.
   []Check Power Management Settings:
   • Make sure that your network adapter's power management settings are not causing any issues:
     • Go to Device Manager, find your network adapter, right-click, and select "Properties."
     • Look for a "Power Management" tab and uncheck any options like "Allow the computer to turn off this device to save power."
   []Network Troubleshooter:
   • Windows has a built-in Network Troubleshooter that can help diagnose and fix network problems:
     • Go to Settings > Update & Security > Troubleshoot > Internet Connections, then run the troubleshooter.
   []Check Network Cable and Router:
   • Since you mentioned that it works fine through a cable, the issue might be with your Wi-Fi network or router. Try these steps:
     • Restart your router.
     • Change the Wi-Fi channel on your router to avoid interference.
     • Make sure your router firmware is up to date.
   []Advanced Steps:
   • If the basic steps don't work, you can try resetting TCP/IP settings or using tools like netsh to reset components.

     Additional Notes:​

     • Windows 7 (build 7600 RTM) is an older version, and Microsoft has ended support for it. Consider upgrading to a newer version to benefit from improved network capability and security features.
     • If your hardware is compatible, you might want to consider upgrading to Windows 10 or Windows 11 for better performance and support.
