Windows has been released and downloaded by millions of users. One of the most annoying problems which certainly needs to be solved as soon as possible is the IPv4 no internet access issue.
In this article, Iโm going to show you what to do if you encounter the IPv4 connectivity no internet access problem on your PC.
What causes the IPv4 connectivity no network access error?
Here are a few reasons you might be getting No Internet access on IPv4 while IPv6 works:
- Outdated, corrupt, incompatible network drivers – In case you haven’t updated the drivers in a while, it could that the installed drivers are outdated, which is causing the error. Also, corrupt or incompatible ones, too, can lead to the issue.
- Third-party application triggering conflicts – Oftentimes, third-party applications, usually an antivirus, can lead to the IPv4 No Internet access error.
- Misconfigured network settings – Incorrect DNS server or IP address, amongst a range of other misconfigured settings, can cause issues with Internet access.
How can I fix the IPv4 No Internet Access issue?
1. Install the latest network drivers
Outdated network drivers are frequently the cause of most Internet connectivity issues. As such, update them as soon as possible.
This can be easily done with a third-party driver updater. Simply download it, run it, and let it automatically scan for any missing, broken, or outdated drivers. You will then get to choose what to do with each and every one of them.
All in all, if you love programs that do the work for you, then you can rely on these to solve the IPv4 not connected issue.
2. Modify the HT Mode settings
- Press Windows + R to open Run, type ncpa.cpl in the text field, and hit Enter.
- Right-click on the active network adapter, and choose Properties.
- Click on Configure.
- Navigate to the Advanced tab, select HT Mode under Property, then choose HT Mode 20|40 under the Value dropdown menu, and click on OK to save the changes.
- Once done, restart the computer for the changes to come into effect.
3. Renew the IP address
- Press Windows + S to open the Search menu, type cmd, right-click on the relevant search result, and select Run as administrator.
- Click Yes in the UAC prompt.
- Now, paste the following two commands one at a time and hit Enter after each:
ipconfig /release
ipconfig /renew
Finally, restart the computer and verify whether the No Internet access error on IPv4 is resolved. If not, head to the next solution.
4. Reset Winsock (Windows Socket API)
- Press Windows + R to open Run, type cmd, and hit Ctrl + Shift + Enter.
- Click Yes in the UAC prompt that appears.
- Now, execute the following two commands one after the other:
netsh winsock reset
netsh int ip reset
5. Check your IP settings
Hereโs how to enable IPv4 and IPv6 protocols:
- Go to Search, type network and open Network and Sharing Center
- Go to Change adapter settings from the left pan
- Right click on your connection device (in most cases itโs called just Ethernet) and go to Properties
- Under This connection uses the following items: check Internet Protocol Version 4 (TCP/IPv4) and Internet Protocol Version 6 (TCP/IPv6)
- Click OK and restart your computer
When you turn your computer back on, you should be able to connect to internet without any problems.
Thereโs a chance that Windows 10 turned off your IPv4 and IPv6 protocols after the installation, this doesnโt happen very often, but it could happen. So logically, all you need to do to get your internet connection back is to turn on these protocols again.
Sometimes, your IPV6 may be enabled but not working. Re-enabling it should fix this issue. However if you are still can’t access the internet on IPv6, we suggest you check out this guide.
6. Change the channel width
- Navigate to Network and Sharing Center from the list of results
- Go to Change adapter settings
- Select your wireless adapter by right-clicking it > go to Properties > Go to Configure
- Select the Advanced tab > select the 802.11 channel width and change the value. Keep using a different value until you’ve established a stable internet connection.
- Save your new settings.
This step applies to wireless networks. By changing the bandwidth settings, you allow your computer to use other wireless frequencies and expand its reach.
7. Disable Internet Protocol Version 6 (IPv6)
- Press Windows + S to open the Search menu, type View network connections, and click on the relevant search result.
- Right-click on the current adapter, and choose Properties.
- Now, uncheck the option for Internet Protocol Version 6 (TCP/IPv6), and click on OK to save the changes.
- Finally, restart the computer.
If nothing else worked, the last solution is to disable IPv6 and force the computer to use IPv4 instead. This solution did the trick for many and should help get things up and running
