3. Solutions for Network Issues in Windows

Solution 1: Update Network Drivers

Driver issues are a common cause of network problems. If you're unfamiliar with manually downloading and installing drivers, it's recommend to use the Driver Talent driver management tool. It can automatically detect missing or outdated drivers and fix them with one click.

Download Driver Talent

Click the download button to get the latest version of Driver Talent. After installation, launch the software and click "Scan".
After scanning, the tool will list drivers that are missing or need updates. Locate your network driver and click the "Update" button.

Solution 2: Restart the Network Adapter

Press Win + R, type "ncpa.cpl", and press Enter.

In the list of network connections, right-click your adapter (e.g., Wi-Fi or Ethernet), and select "Disable".

This helps reset the adapter's status and may restore connectivity.

Solution 3: Run the Network Troubleshooter

Solution 4: Reset TCP/IP and DNS

Open Command Prompt (Admin) and run the following commands:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns

Then restart your computer. This clears corrupt protocol settings and DNS cache.

Solution 5: Change DNS Settings

Go to Control Panel > Network and Sharing Center > Change adapter settings.

Right-click your "network connection" > "Properties".

Double-click "Internet Protocol Version 4 (TCP/IPv4)".

Select Use the following DNS server addresses:

Alternate DNS: 8.8.4.4

Save and test your connection

Solution 6: Disable Firewall or Security Software

Some antivirus or firewall software may block network access.

Try temporarily disabling them and check if the network works again.
If they're the cause, consider switching to a more compatible security tool.

Solution 7: Restart the Router

Unplug the router's power for 1–2 minutes, then plug it back in.

Check if cables are properly connected.

You may also consider resetting the device to factory settings (do this with caution).

Avoid installing unknown optimization software
Properly configure firewall and antivirus permissions
Use built-in troubleshooting tools when problems arise
