如果您在 PC 上遇到“ IPv6 连接^{(IPv6 Connectivity)}：无Internet访问”问题，请不要担心，因为今天我们将了解如何解决此问题。如果您将打开网络^(Network)和共享中心，或者按Windows Key + R然后键入 ncpa.cpl 并按Enter，然后右键单击您的网络连接并选择Status，您将在IPv6 Connectivity下看到No Internet Access。

如果在IPv6 Connectivity下显示“No network access”，则表示未检测到DHCP服务器并且未分配链接本地地址，这不是问题，无需担心。但如果它显示“无法访问 Internet”，则表示检测到DHCP服务器，但未分配链接本地地址，这意味着您的IPv6配置有问题。我希望现在很清楚“无法访问网络”和“无法访问互联网”是两个完全不同的主题。

什么是 IPv6？

Internet 协议版本 6^{(Internet Protocol Version 6)} ( IPv6 ) 处理所有通信协议，支持通过分组交换网络进行数据通信。IPv6由Internet 工程任务组^{(Internet Engineering Task Force)}( IETF ) 开发，旨在克服IPv4地址耗尽的问题。IPv6是Internet 协议版本 4^{(Internet Protocol Version 4)} ( IPv4 ) 的继任者，并且在未来，IPv6旨在取代IPv4。

Windows 10 上 IPv6 无法访问 Internet 的主要原因是什么？^{(What is the main cause of IPv6 No Internet Access on Windows 10?)}

IPv6不支持很多设备，并且允许它的ISP较少，默认情况下不启用。^(ISP)但可能还有其他原因，例如网络驱动程序损坏、过时或不兼容、IP 配置损坏以及防火墙^(Firewall)可能阻止连接、病毒或恶意软件感染等。

如您所见，您面临“ IPv6 连接^{(IPv6 Connectivity)}：无Internet访问”问题的原因可能有多种，因为不同的用户有不同的配置和系统环境，所以如果某件事适用于一个用户并不一定意味着它会为您工作，因此，您需要尝试尽可能多的方法。现在，不要浪费任何时间，让我们在下面列出的故障排除指南的帮助下，看看如何在Windows 10上^{(Windows 10)}修复 IPv6 连接无法访问 Internet 。^{(Fix IPv6 Connectivity No Internet Access)}

Fix IPv6 Connectivity No Internet Access on Windows 10

If you’re facing “IPv6 Connectivity: No Internet access” issue on your PC then don’t worry as today we are going to see how to fix this issue. If you will open Network and sharing center, or press Windows Key + R then type ncpa.cpl and hit Enter, then right-сlick on your network connection and select Statυѕ, you will see under IPv6 Connectivity that there is No Internet Access.

If under IPv6 Connectivity it says “No network access” then it means that the DHCP server was not detected and no link-local address was assigned, which is not a problem and there is nothing to worry about. But if it says “No internet access” then it means that a DHCP server was detected, but no link-local address is assigned which means there is something wrong with your IPv6 configuration. I hope now it’s clear that “No network access” and “No internet access” are two entirely different topics.

What is IPv6?

Internet Protocol Version 6 (IPv6) handles all the communications protocol, enabling data communications over a packet-switched network. IPv6 was developed by the Internet Engineering Task Force (IETF) to overcome the problems of IPv4 address exhaustion. IPv6 is the successor to Internet Protocol Version 4 (IPv4), and in future, IPv6 is intended to replace IPv4.

What is the main cause of IPv6 No Internet Access on Windows 10?

IPv6 is not capable of many devices, and fewer ISP allows it, and it is not enabled by default. But there can be other reasons such as corrupted, outdated, or incompatible network drivers, corrupted IP configuration, and Firewall might be blocking the connection, virus or malware infection etc.

So as you can see, there can be various reasons as to why you are facing the “IPv6 Connectivity: No Internet access” issue as different users have different configuration and system environment, so if something works for one user not necessarily means it will work for you and therefore, you need to try as many methods as possible. Now without wasting any time let’s see How to Fix IPv6 Connectivity No Internet Access on Windows 10 with the help of the below-listed troubleshooting guide.

Fix IPv6 Connectivity No Internet Access on Windows 10

Make sure to create a restore point just in case something goes wrong.

Method 1: Reset IPv6 and Winsock

1. Open Command Prompt. The user can perform this step by searching for ‘cmd’ and then press Enter.

2. Type the following command into cmd one by one and hit Enter after each one:

• ipconfig /flushdns
• nbtstat –r
• netsh int ip reset
• netsh winsock reset
• netsh winsock reset catalog
• netsh int ipv6 reset reset.log

3. Reboot to apply changes. Netsh Winsock Reset command seems to Fix IPv6 Connectivity No Internet Access on Windows 10.

Method 2: Update your network drivers

First, go to your manufacturer’s website either your laptop manufacturer (ex: Dell, Acer, etc.) or your network adapter manufacturer (ex: Intel, Qualcomm etc.) then download the latest driver from the driver’s downloads section.

Note: You will need another PC to download the drivers and then install the downloaded drivers on the PC on which you’re facing the issue “IPv6 Connectivity: No Internet Access”.
