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.
How To Fix the Error “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An outdated or broken network adapter driver is another possible culprit.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.
If you’ve been experiencing “IPv4 no internet access,” hopefully one of the aforementioned steps will have helped you reconnect to the web. Try Windows’ built-in Internet Connections Troubleshooter if that doesn’t work.
Although troubleshooters are not a silver bullet for computer problems, they are usually the first line of defence. Additionally, it has the potential to fix the “IPv4 has no internet access” issue.
