How To Fix ‘IPV4 No Internet Access’ Issue

You have a helpful option with your High Throughput (HT) Mode settings, but it does have some drawbacks. Users can choose between Very High Throughput (802.11ac) and High Throughput (802.11n) data rates by adjusting these settings on their computers.

Consequently, you can adjust these parameters to resolve the IPv4 connection failure. Internet Protocol version 4 (IPv4) is an essential part of our internet ecosystem, facilitating data packet routing and ensuring seamless communication between devices.

Although it’s a robust and reliable technology, users often face issues like ‘No Internet Access,’ disabled connections, or confusion about IP addresses.

IPV4 No Internet Access

In this SEO-optimized article, we’ll deep-dive into what IPv4 is, common issues, and how to enable, check, or change your IPv4 connection.

What is IPv4?

IPv4 is the fourth version of the Internet Protocol, responsible for identifying devices on a network through an addressing system. The protocol uses 32-bit addresses, typically displayed as four decimal numbers separated by dots (e.g.,

Causes of IPv4 No Internet Access

While IPv4 is generally stable, ‘No Internet Access’ errors can occur. Some common causes are:

  1. Network Congestion: Too many devices connected to the same network can cause this issue.
  2. Faulty Router: An outdated or malfunctioning router can disrupt your IPv4 connectivity.
  3. ISP Outage: Sometimes, the issue lies with your Internet Service Provider (ISP).
  4. Incorrect IP Configuration: Manually setting the IP address incorrectly can lead to no internet access.

How To Fix the Error “IPV4 No Internet Access”

IPV4 No Internet Access


Method 1. Modify Your System’s Network Drivers.

An outdated or broken network adapter driver is another possible culprit. If you wish this issue to stop happening again, you should upgrade these network drivers to the most recent version available.

Checking the manufacturer’s website for your device and manually installing any updates is the best and easiest approach to update your drivers. You can also use Device Manager to access online driver updates. You can’t check the manufacturer’s website for updates as you can’t connect to the internet.

Method 2. It’s Time to Reset Your IP Address.

Every node on a network is assigned a different number known as an Internet Protocol (IP) Address. Because of this address, devices can communicate with one another within a closed network. Your IP address may have expired or been incorrectly assigned; in any case, you’ll need to release and renew it before you can make a full connection.

If you want to alter your IP address, you can do so by opening the Run dialogue box by pressing the Windows key plus R. Simply entering “cmd” into the bar and hitting enter will launch a command prompt.

Enter “ipconfig/release” and go to the next step. When the command prompt reappears, type “ipconfig/renew” and hit enter. Just hit enter after typing “exit” to close the window.

Method 3. IPv6 Deactivation

IPv6, which is intended to eventually replace IPv4, is not expected to be fully operational for at least a few more years. IPv6 is the ideal network mode, although Windows and your ISP and other devices already utilise it. Unless you have a compelling need to utilise IPv6, you may want to try compelledly switching Windows to IPv4 mode.

Pressing the Windows key plus R will bring up the Run dialogue box, where you can manually disable IPv6 mode. Enter “ncpa.cpl” into the search bar to launch the Network Connections panel.

To access the connection’s settings, right-click on it and select “properties.” Internet Protocol Version 6 (TCP/IPv6) can be disabled by deselecting the corresponding box on the Networking page, then clicking OK. To make these changes permanent, a computer restart is required.

There are additional Microsoft-hosted tools available for automating the shutdown of IPv6. If you’d rather use IPv4 addresses instead of IPv6 addresses in your prefix policy, you can get a handy tool from the website and install it on your computer from there.

Alternatively, you can use the “Disable IPv6” tool to turn off IPv6 for good. Keep in mind that you can undo any of these steps at any time.

Method 4. Turn Off Any Security or Firewall Programmes.

McAfee and other antivirus programmes have been widely criticised for contributing to the IPv4-related internet access crisis. Automatic download and installation of firewall programmes and other software may be possible with such tools. Therefore, you should disable these firewall apps entirely rather than just using their interface.

Press the Windows key plus the letter R to open the Run dialogue box, then type “appwiz.cpl” and hit Enter to open Programs and Features and remove the firewall software. Use the scroll bar to access firewall software like McAfee and Avast.

Once you’ve located the unwanted software, simply right-click on it and select “uninstall” from the menu that appears. Don’t forget to remove the firewall and antivirus software as well, as they may leave behind leftover files and programmes.

How Do I Enable IPv4 Connection?

Enabling IPv4 depends on your operating system. For Windows:

  1. Open Control Panel: Navigate to Network and Internet > Network and Sharing Center.
  2. Change Adapter Settings: Find your connection and right-click to choose ‘Properties.’
  3. IPv4 Properties: Scroll to ‘Internet Protocol Version 4 (TCP/IPv4)’ and ensure it is enabled. Click OK.

For macOS:

  1. Open System Preferences: Navigate to Network.
  2. Choose Connection: Select your network connection and click ‘Advanced.’
  3. Configure IPv4: Under the ‘TCP/IP’ tab, choose ‘Using DHCP’ from the ‘Configure IPv4’ dropdown menu.

Is IPv4 My IP Address?

Your IPv4 address is indeed your IP address when you’re using an IPv4 connection. You can typically find this in the network settings of your operating system or by searching “What is my IP address” on Google.

Why Is IPv4 Disabled?

IPv4 may be disabled due to various reasons, including security measures, incorrect network settings, or ISP issues. It can also happen when IPv6 is preferred and takes over, rendering IPv4 redundant in that network setup.

How Do I Change My IPv4 Address?

Changing your IPv4 address can be done manually via your device’s network settings. However, you should proceed with caution, as an incorrect configuration can lead to network issues. Always consult your network administrator or ISP before making changes.

How Do I Check My IPv4 Connection?

You can check your IPv4 connection status via the network settings on your computer. Additionally, command-line tools like ping and ipconfig (Windows) or ifconfig (macOS/Linux) can be used to diagnose IPv4 connectivity.

Should I Disable IPv4 on My Router?

Disabling IPv4 is generally not recommended unless you are on an IPv6-only network and sure that none of the devices on your network require IPv4. Most modern networks are dual-stack, supporting both IPv4 and IPv6 for broader compatibility.
