How to Fix Windows 10 Error: Can’t Connect to This Network

Windows 10 is a powerful and user-friendly operating system, but like all software, it’s not without its issues. One common problem that many users encounter is the dreaded error message: “Can’t connect to this network.” This can be especially frustrating if your work or entertainment depends on a stable internet connection. Understanding what’s causing this error and how to effectively resolve it can save users time and stress.

Common Causes of the “Can’t Connect to This Network” Error

The error can occur due to a variety of reasons, ranging from hardware issues to software misconfigurations. Some of the most frequent causes include:

Corrupted or outdated network drivers
Incompatible Wi-Fi settings
Changes in router configuration
IP address conflicts or DHCP errors
Issues caused by recent Windows updates

Now that the potential issues are identified, let’s explore the step-by-step solutions to fix this problem.

1. Restart Your Devices

Sometimes, the simplest solution is also the most effective. Restart your computer and router/modem. This can clear temporary glitches in the network interfaces and often resolves connectivity issues.

2. Forget and Reconnect to the Network

Removing the problematic Wi-Fi network from your PC and reconnecting can fix configuration-related issues:

Click the Wi-Fi icon in the taskbar.
Right-click on the network you’re trying to connect to and choose Forget.
Reconnect by selecting the network and entering the password.

If the issue persists, proceed to the more advanced steps below.

3. Update or Roll Back Network Drivers

Outdated or corrupted network drivers are a leading cause of connection problems. Here’s how to update them:

Press Windows + X and select Device Manager.
Expand Network Adapters.
Right-click on your wireless adapter and select Update driver.
Choose Search automatically for updated driver software.

If you’ve recently updated your drivers and the issue started afterward, a rollback might help:

Right-click the adapter and choose Properties.
Go to the Driver tab and click Roll Back Driver, if available.

4. Use the Network Troubleshooter

Windows 10 comes with a built-in network troubleshooter that can automatically detect and repair common problems:

Go to Settings > Network & Internet > Status.
Scroll down and click Network troubleshooter.
Follow the on-screen prompts to diagnose the issue.

5. Change Wireless Network Mode

Sometimes, the wireless mode on your adapter is not compatible with your router. Adjusting this setting can help:

Open Device Manager and expand Network Adapters.
Right-click your adapter and select Properties.
Go to the Advanced tab and find Wireless Mode.
Change the value to a different mode (e.g., from 802.11n to 802.11g).
Click OK and restart your PC.

6. Disable IPv6 Protocol

In some situations, the IPv6 protocol can interfere with network connectivity. Disabling it can be beneficial:

Go to Control Panel > Network and Sharing Center.
Click Change adapter settings on the left.
Right-click your network and select Properties.
Untick the box for Internet Protocol Version 6 (TCP/IPv6).
Click OK to save changes.

7. Reset TCP/IP Stack

Resetting the TCP/IP stack can correct numerous underlying network issues. This process uses Command Prompt:

Open Command Prompt as Administrator.
Type the following commands, pressing Enter after each:
- netsh winsock reset
- netsh int ip reset
- ipconfig /release
- ipconfig /renew
- ipconfig /flushdns
Restart your computer.

8. Check Router Settings

If your PC shows the error only for one specific network, the issue could lie within the router settings:

Log in to your router’s web interface (usually 192.168.1.1 in a browser).
Check for MAC address filtering and make sure your device is allowed.
Ensure the SSID is broadcasting and encryption settings are compatible (e.g., WPA2).
Change the wireless channel to avoid interference.

9. Reinstall Network Adapter

Reinstalling the network adapter can eliminate corrupted configurations:

Open Device Manager.
Right-click your wireless adapter and select Uninstall device.
Reboot your system. Windows will reinstall the default drivers automatically.

10. Check for Windows Updates

Microsoft frequently releases fixes and patches for system bugs. Installing the latest updates may solve hidden issues:

Open Settings > Update & Security > Windows Update.
Click Check for updates.
Download and install any available updates.

11. Perform a Network Reset

If none of the above steps work, performing a full network reset can restore default settings:

Go to Settings > Network & Internet > Status.
Click Network reset at the bottom of the page.
Click Reset now and follow the prompts.

Be aware that this will remove all saved networks and VPN connections, so use it as a last resort.
