Sometimes you’ll see that frustrating yellow exclamation point icon over your network connection icon in Windows. The OS offers to troubleshoot it for you, but after running through the automatic tool, you see this message:
Windows could not automatically detect this network’s proxy settings.
What does this mean, and how do you fix it? Let’s take a look at Windows’ proxy settings and the steps to repair this.
1. Reboot Your Computer and Router
Before you launch into advanced troubleshooting, it’s always a good idea to restart your equipment first. There’s a chance that this will clear up your issue in a few moments.
Because this error is usually related to misconfigured settings on one computer, restarting your router likely won’t have an effect. But it’s still worth a try whenever you run into network problems of any kind.
If you reboot your computer and router and the problem hasn’t fixed itself, continue on with the more detailed steps.
2. Review Proxy Settings in Windows
One Switch for Mac Gives You Quick Access to Useful Settings in the Menu Bar

Activating Dark Mode on your Mac or showing hidden files might not seem like much of a chore. But try to access these...
The post One Switch for Mac Gives You Quick Access to Useful Settings in the Menu Bar appeared first on Y8 VN.
Because this issue is related to your Windows proxy settings, that’s a sensible first place to check. To access proxy settings in Windows 10, open Settings, select the Network & Internet category, and switch to the Proxy tab from the left sidebar.
Here you’ll see a list of options related to proxy servers. If you don’t use a proxy (as is the case for most home users), make sure the Use a proxy server slider is turned off. Leave Automatically detect settings on if it is already.
For users who do connect with a proxy, such as in a work or education environment, you might want to check with your system administrator to make sure you have the correct proxy details.
After this, try reconnecting to the network again. If you still get the error, try turning off Automatically detect settings in the proxy options and try once more.
What’s a Proxy Server?
We don’t want to bore you with the details while you try to fix this issue but wanted to provide a brief explanation of what a proxy actually is and why Windows can run into problems with it.
Essentially, a proxy server acts as a middleman between your computer and the internet. Instead of you connecting directly to the internet, you connect to the server, which grabs information from the internet for you.
These are most common in business and school use, where system administrators use them for security and efficiency. It’s very unlikely that you would use a proxy server on your home network unless you specifically set one up. This is why you should clear any proxy settings that might exist when you run into this issue.
See our full explanation of proxy servers for more information.
3. Run the Network Adapter Troubleshooter
When you right-click on the network connection icon and choose to troubleshoot, it runs the Internet Connections troubleshooter, resulting in the “Windows could not detect proxy settings” error. But there’s another network troubleshooter you can run that might provide more help.
Open Settings again and visit Update & Security > Troubleshoot. Find Network Adapter in the list and walk through the troubleshooter for this. As seasoned Windows users know, this tool doesn’t always fix your problem, but it’s worth a try.
4. Auto-Obtain IP Address and DNS
As it turns out, there aren’t many troubleshooting steps specific to proxy servers. We’ll share more tips below, but bear in mind that the troubleshooting looks similar to fixing the “No Internet Access” Windows error from this point on.
While they’re not technically related to your proxy settings, misconfigured IP address or DNS settings can cause this error too. To check them, browse to Settings > Network & Internet > Status. Click the Change adapter options button in the list to see all your network connections, then double-click on the one you’re using.
Here, click the Properties button and double-click Internet Protocol Version 4 in the list. Make sure you have both Obtain an IP address automatically and Obtain DNS server address automatically selected. Misconfigured settings here will prevent you from getting online.
5. Update or Roll Back Your Network Driver
Plex Launches a Free Streaming Service

Plex has launched its own free streaming service full of movies, TV shows, and documentaries. Plex is offering thousands of pieces of content...
An outdated network driver may lead to connection problems. Similarly, perhaps you’ve recently installed a botched update for your network driver. In either case, replacing it might clear up the trouble.
Right-click on the Start Button and choose Device Manager to open this utility. Expand the Network adapters section and double-click on the connection you use.
On the Driver tab, you can choose Roll Back Driver to uninstall the latest update and return to the previous one. Use this if you started experiencing this issue after updating.
Choose Update Driver and you can check for new updates over the internet. This likely won’t find anything though, so you’ll need to manually download the latest driver from your machine’s manufacturer. See our guide to updating Windows drivers for help.
6. Reset Network Configuration Via the Command Prompt
Windows offers many network troubleshooting tools through the Command Prompt. A few quick commands can clear up your issue in moments. If you’re still having trouble at this point, right-click the Start Button again and open a Command Prompt (or PowerShell) as Administrator.
Then run the following commands, one at a time. They will reset various network functions of your computer:
netsh winsock reset
netsh int ip reset
7. Review Firewall, VPN, and Antivirus Software
You should next make sure you don’t have a firewall, VPN, or security suite interfering with your network connection. Perhaps your chosen software had an update that changed some settings you weren’t aware of, or you just installed a new app.
Try disabling your firewall, VPN, and antivirus software one at a time, then see if the error goes away. If it does, the issue lies with one of those apps. You’ll need to configure them to avoid interfering with regular network activity.
8. Scan for Malware
Some malware has been known to continually mess with your proxy settings to prevent you from getting online. If you run into the “Windows could not detect this network’s proxy settings” message every time you reboot, you may be a victim of this.
You should thus run a scan with a trusted anti-malware app, such as Malwarebytes. This will detect any viruses or other malware running on your system and get rid of them. If the scan finds any infections, take the recommended action and see if your connection works as normal again.
9. Utilize a Restore Point
The System Restore feature in Windows lets you return to a previous point when your computer was working normally. If your issues started recently, you should try this to see if you can go back in time.
Search for Control Panel in the Start Menu to open it. If Category is selected in the top-right, switch to Small or Large icons and choose the System entry.
Next, click System protection on the left sidebar. In the resulting dialog box, click System Restore to open a new window. Windows will walk you through choosing a restore point and confirming the operation. Of course, if your computer hasn’t created any restore points, you can’t use this feature.
Note that using a restore point will remove any programs and drivers you installed since making that restore point. You can click Scan for affected programs on a restore point to see what effect it will have. A System Restore won’t affect any of your personal information.
10. Reset Your Network Settings
After trying everything above, you should resort to a full reset of your network options. You’ve already spent a lot of time working on this, and a reset should clear whatever persistent problem is blocking your connection.
Thankfully, Windows 10 makes it easy to reset your whole configuration. Open Settings > Network & Internet. On the Status tab, find Network reset at the bottom and click this.
Be aware that this will remove all network information from your computer, so you’ll need to reconnect to saved networks again. If you’re OK with this, click Reset now. Your computer will perform the reset, then restart.
More on Network Troubleshooting
Now you know what to do when Windows cannot detect proxy settings. All network errors are frustrating, but you should be able to clear this one up without much work. It’s most important to make sure that you have a proxy turned off (if you don’t use one) or configured properly (if you do use one).
Otherwise, some standard network troubleshooting should have you all patched up. We have an extensive guide to Windows network troubleshooting if you need more help.
