Why Is Your Internet Not Working?

There can be several reasons behind internet issues, ranging from minor configuration errors to deeper network-related problems. Some of the most common causes include:

• A faulty Ethernet or Wi-Fi adapter

• Incorrect network settings

• ISP (Internet Service Provider) outages

• Router/modem issues

• Software conflicts or malware

• Outdated network drivers

Identifying the root cause is crucial to applying the correct fix.

How to Fix Internet Connection Issues: Step-by-Step Guide

1. Check Physical Connections

Before diving into software fixes, inspect your hardware. Ensure your Ethernet cable is securely plugged in or that your Wi-Fi is enabled. Sometimes, simply unplugging and re-plugging the cable or restarting the router can resolve the issue.

2. Restart Your PC and Router

This is the classic tech tip for a reason. Restarting your devices helps clear out temporary glitches that may be causing the issue.

• Turn off your router and modem.

• Wait for 30 seconds.

• Restart your PC.

• Turn your router/modem back on and wait until all lights are stable.

3. Run the Windows Network Troubleshooter

Windows comes with a built-in troubleshooter that can automatically detect and fix common internet problems:

• Go to Settings > Network & Internet > Status.

• Click on Network Troubleshooter.

• Follow the on-screen instructions.

4. Check Network Settings

Verify if your PC is getting an IP address from the router:

• Press Windows + R, type cmd, and press Enter.

• Type ipconfig /all and check your IP address.

• If your IP starts with 169. x.x.x, your PC is not receiving a valid IP. Reset your router and try again.

5. Update Network Drivers

Outdated or corrupted drivers can cause network problems. Here’s how to update them:

• Open Device Manager.

• Expand Network Adapters.

• Right-click on your adapter and select Update driver.

• Choose Search automatically for updated driver software.

6. Reset TCP/IP and DNS

Corrupted TCP/IP settings can be fixed using the Command Prompt:

• Open Command Prompt (Admin)

• Type the following commands one by one and press Enter after each:

  • netsh int ip reset

  • ipconfig /release

  • ipconfig /renew

  • ipconfig /flushdns

• Restart your PC

7. Check for Malware

Sometimes, malicious software can hijack your network settings. Run a full scan using Windows Defender or a trusted third-party antivirus tool.

8. Disable and Re-enable Network Adapter

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

• Right-click on your connection and choose Disable

• After a few seconds, right-click again and choose Enable
  

Advanced Fixes for Persistent Issues

Change DNS Server Settings

Sometimes switching to public DNS servers can resolve connectivity problems:

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

• Right-click on your active connection > Properties

• Select Internet Protocol Version 4 (TCP/IPv4) > Properties

• Choose Use the following DNS server addresses:

  • Preferred DNS server: 8.8.8.8

  • Alternate DNS server: 8.8.4.4

Check Router Settings

Log in to your router admin panel (usually by typing 192.168.1.1 or 192.168.0.1 into your browser) and:

• Make sure DHCP is enabled

• Check if MAC address filtering is off

• Ensure the firmware is updated

Contact Your ISP

If none of these fixes work, your ISP may be experiencing outages. Contact them for support.
