No Internet Connection? How to Diagnose and Fix the Issue

It’s super annoying when your internet stops working. Whether you’re using Wi-Fi or a wired connection, losing access can be a big problem. But don’t worry! There are some easy steps you can follow to find out what’s wrong and fix it. This guide will help you get back online quickly.

Key Takeaways

• Restarting your modem and router can often fix connection issues.
• Check all cables and wires to make sure they are properly connected and not damaged.
• Adjusting your Wi-Fi adapter settings can help resolve connectivity problems.
• Running Windows Network Diagnostics can identify and fix many common internet issues.
• Resetting network settings should be a last resort if other troubleshooting steps fail.

Restart Your Modem and Router

When your internet connection drops, one of the first things you should try is restarting your modem and router. This simple step can often resolve many connectivity issues. Here’s how to do it effectively:

Power Cycle Your Devices

To start, unplug the power cable from both your modem and router. Wait at least 30 seconds to ensure all the temporary memory is cleared. Then, plug the modem back in and turn it on. Wait another 60 seconds before plugging in and turning on the router.

Wait for Reboot

After powering your devices back on, give them a few minutes to fully reboot. This process can take anywhere from two to five minutes. During this time, the devices are re-establishing their connection to your internet service provider (ISP).

Check Connection Status

Once your modem and router have rebooted, check to see if your internet connection has been restored. You can do this by opening a web browser and trying to visit a website. 

If your internet issues persist, it might be time to consider upgrading to a more reliable service.

Check Physical Connections and Hardware

When you’re having trouble with your internet, it’s important to check the physical connections and hardware first. This can often solve the problem quickly and easily.

Inspect Cables and Wires

Begin by checking all the cables and wires linked to your modem and router. Ensure they’re firmly connected and free from any damage. Often, loose or worn-out cables are behind common connectivity problems.

Verify Router and Modem Lights

Next, take a look at the lights on your router and modem. A solid green or white light usually means everything is working fine. If you see a different colour or a flashing light, refer to your router’s manual to understand what it means. This can help you identify if there’s a problem with the hardware.

Test with Another Device

Finally, try connecting to the internet with another device, like your phone or tablet. This will help you determine if the issue is with your device or the router/modem. If your phone connects normally, then the problem is likely with your computer. 

When dealing with connection issues, choosing the right internet provider makes all the difference.

Evaluate Wi-Fi Adapter Settings

When you’re having trouble with your internet connection, it’s important to check your Wi-Fi adapter settings. This can often resolve issues that other troubleshooting steps might miss. Here’s how to do it:

Access Device Manager

First, you need to open the Device Manager on your computer. This tool lets you see all the hardware connected to your system. To access it, type “Device Manager” into the search bar and click on the result. Once you’re in, look for the section labelled “Network adapters.” This is where you’ll find your Wi-Fi adapter.

Check Wireless Mode

Next, you should check the wireless mode of your adapter. Right-click on your Wi-Fi adapter and select “Properties.” Then, go to the “Advanced” tab. Here, you’ll see a list of properties. Look for one called “Wireless Mode” or something similar. Make sure it matches the type of network you’re trying to connect to, like 802.11ac for newer networks.

Update Adapter Drivers

Finally, it’s crucial to keep your adapter drivers up to date. Outdated drivers can cause a lot of issues. Right-click on your Wi-Fi adapter again and select “Update driver.” Choose the option to search automatically for updated driver software. If an update is found, follow the on-screen instructions to install it. Keeping your drivers updated can solve many connectivity problems.

Run Windows Network Diagnostics

When you’re facing internet issues, running Windows Network Diagnostics can help identify and fix the problem. Here’s how to do it:

Open Network Troubleshooter

First, navigate to Windows Settings by clicking on the Start menu and selecting the gear icon. Go to Network & Internet and then click on Status. From there, open Network Settings and select Network Troubleshooter. This tool will run a series of tests to find out what’s causing the issue.

Follow On-Screen Instructions

Once the troubleshooter starts, it will guide you through a series of steps. Follow the on-screen instructions carefully. If the tool finds any issues, it will provide a list of possible actions you can take to fix your connection.

Adjust DNS Settings

Sometimes, the problem might be with your DNS settings. Many routers use themselves as DNS servers by default, which can cause issues. To manually change your DNS settings, go to your Network Interface Card (NIC) configuration and replace the primary and secondary DNS servers with Google’s DNS (8.8.8.8 and 8.8.4.4). This can often resolve connectivity problems.

Reset Network and Internet Explorer Settings

When you have no internet connection, resetting your network and Internet Explorer settings can often resolve the issue. Here’s how to do it:

Perform Network Reset

A network reset can be a powerful tool to fix connectivity problems. However, it should be one of the last steps you try, as it will remove all network adapters and reset network settings to their defaults. To perform a network reset on Windows:

1. Open Settings > Network & Internet > Advanced network settings > Network reset.
2. Click on Reset Now and confirm by selecting Yes.

For Apple devices:

1. Open the Apple menu > System Preferences > Network.
2. Select your Wi-Fi name, click the minus symbol, and select Apply.
3. To set up your connection again, click the plus icon, choose your Wi-Fi network, and hit Apply.

Reset Internet Explorer Settings

If you’re using Internet Explorer, resetting its settings can help restore your connection. Follow these steps:

1. Close all open programs.
2. Open Internet Explorer > Tools > Internet options, and select the Advanced tab.
3. Open Reset Internet Explorer Settings and click Reset.
4. Wait for the default settings to restore, select Close > OK, then restart your device.

Restart Your Device

Sometimes, a simple restart can solve many issues. Restarting your device can clear the cache and ensure that all settings are applied correctly. We see this happen frequently. After making changes, it’s often only after restarting that the fixes take effect.

By following these steps, you can often resolve no internet connection issues and get back online.

Advanced Troubleshooting Techniques

Flush DNS Cache

Sometimes, your DNS cache can cause connectivity issues. To clear it, open the Command Prompt on Windows and type ipconfig /flushdns, then hit Enter. On a Mac, open the Terminal app and enter the command based on your OS version. This can help resolve issues caused by a corrupted cache.

Update Network Drivers

Outdated network drivers can lead to connection problems. To update them, go to Device Manager, find your network adapter, right-click, and select Update driver. Follow the prompts to complete the update. Keeping your drivers up-to-date ensures better performance and fewer issues.

Disable VPN Temporarily

At times, a VPN can disrupt your internet connection. You can try turning off the VPN for a moment to check if that fixes the problem. If it works, adjusting the VPN settings or reaching out to your VPN provider for help might be necessary. If the issue persists, you may need to consider more advanced troubleshooting or get in touch with VMedia for additional support.
