Windows has a built-in troubleshooting tool that lets you diagnose connectivity problems on your computer. When this tool detects a problem with your network, it fixes them automatically. Sometimes, it points out the problem and recommends probable solutions. At other times, the network troubleshooter describes the problem without proffering any solution.
A good sợ hãixample of the third instance is the “Windows could not automatically detect this network’s proxy settings” kinh hoảngrror. Obviously, this message tells you that there’s a problem with your network’s proxy settings. What it doesn’t reveal is how to fix the problem.
That’s because issues relating to proxy configurations are multifaceted and often complex to fix, particularly if you don’t know where to look or what to do.
Rebooting your router and computer may fix the problem. If the issue continues, one of the 9 troubleshooting solutions listed below should do the magic.

Wait for about 10-30 seconds and re-enable the network adapter. Select the network and click Enable this network device.
2. Check Adapter IP Settings
If the kinh hoàngrror persists and you still cannot access the internet, disable any manual IP address or DNS configuration assigned to your network adapters. Allowing Windows to automatically obtain IP and DNS server addresses for your connections can sợliminate this kinh hồnrror.

Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
In the General tab, select Obtain and IP address automatically and Obtain DNS server address automatically. Select OK to save.
3. Disable Proxies, Firewalls, and VPN
Routing your internet through firewalls, VPNs, and proxies can cause network interference that result in hoảngrror messages like “Windows could not automatically detect this network’s proxy settings.” Disable your VPN, firewall, and other network apps and check if that restores internet access.

You’ll find the name of your PC’s Ethernet and Wi-Fi drivers labeled below the network types. Now you know which driver to update in the Device Manager.
3. Next, select Search automatically for updated driver software.

2. Go to the Driver tab and click the Roll Back Driver button.
