Error: "Windows Could Not Automatically Detect Network Proxy Settings" – How to Fix It

The message "Windows could not automatically detect network proxy settings" typically appears when your system can't properly configure the proxy settings, which may disrupt your internet connection by slowing it down or even blocking access. This guide covers the main causes of this error and the steps to resolve it.

Primary Causes of the Error

  • Incorrect network settings: Issues with proxy or network configurations can trigger this error.
  • IP or DHCP configuration errors: If IP or DNS settings are misconfigured, Windows may fail to detect the proxy.
  • Interference from antivirus or firewall: Some security programs may block automatic proxy detection.
  • Windows service glitches: Certain network services may be malfunctioning, leading to this error.

Ways to Resolve the Error

1. Restart Your Router and Computer

Simply rebooting your network can help clear temporary issues. Turn off your router for 10-15 seconds, then turn it back on. Restart your computer as well.

2. Check Proxy Settings

  1. Open Windows Settings (Win + I) and select Network & Internet.
  2. Go to the Proxy tab.
  3. Disable all proxy settings if they’re enabled.

3. Reset TCP/IP Settings

Try resetting network settings via Command Prompt:

netsh int ip reset

After running the command, restart your computer.

4. Clear DNS Cache

Sometimes clearing the DNS cache can help restore proper network settings:

ipconfig /flushdns

5. Update Network Drivers

  1. Open Device Manager (Win + X → Device Manager).
  2. Find your network adapter, right-click it, and select Update Driver.

6. Disable Antivirus and Firewall Temporarily

Temporarily disable your antivirus and firewall to check if they’re interfering with network settings. If the issue is resolved, you may need to add exceptions in your security software.
