一些Windows用户在尝试连接到Windows 11或 Windows 10 计算机上的网络时可能会遇到IPv6 Connectivity, No network access错误。(IPv6 Connectivity, No network access)在这篇文章中,我们确定了潜在的触发因素,并提供了最充分的解决方案来解决问题。
为什么IPv6说没有网络访问权限?
如果您在Windows(Windows) PC 上遇到IPv6 No internet access 问题,很可能是由于您使用了错误的以太网驱动程序,或者它已过期或损坏或损坏。无论如何,要解决此问题,请更新您的以太网网卡驱动程序。此错误最可能的罪魁祸首包括 -
- 不正确的 HT 模式设置。
- 过时的网络适配器驱动程序。
- DNS 和 IP 地址不正确。
- 第三方杀毒软件。
修复 IPv6 连接(Fix IPv6 Connectivity),无网络访问错误
如果您遇到此IPv6 Connectivity, No network access error,您可以尝试以下我们推荐的解决方案(不分先后顺序),看看是否有助于解决问题。
- 重新启动 PC 和 Internet 设备
- 暂时禁用第三方安全软件(如果适用)
- 卸载VPN客户端(如果适用)
- 运行网络疑难解答

- 使用 IPv4。
让我们看一下关于列出的每个解决方案所涉及的过程的描述。
在尝试以下解决方案之前,请确保IPv6 已启用,并检查更新并在(check for updates)Windows设备上安装任何可用位,并查看错误是否再次出现。
1]重新启动PC和Internet设备
解决该错误的第一步是重新启动您的 PC(restart your PC)以及您的 Internet 设备(调制解调器/路由器)。
2]暂时(Temporarily)禁用第三方安全软件(如果适用)
此解决方案要求您使用AV 专用删除工具(AV dedicated removal tool)禁用或最好卸载安装在 Windows 10/11 PC 上的任何第三方安全软件。
要禁用您的防病毒软件,请在任务栏上的通知区域或系统托盘中找到其图标(通常位于桌面的右下角)。右键单击该图标并选择禁用或退出程序的选项。
3]卸载VPN(Uninstall VPN)客户端(如果适用)
如果您在 Windows PC 上通过VPN主动连接,您可能会遇到此错误。(VPN)在这种情况下,您可以卸载 VPN 软件(uninstall the VPN software),看看是否有助于解决问题。
4]运行网络疑难解答
此解决方案要求您运行网络疑难解答来解决 Windows 11/10 计算机上的任何网络相关问题。
5]Release/Renew IP,重置Winsock,刷新DNS
此解决方案要求您释放和更新 IP、重置 Winsock 和刷新 DNS(release and renew IP, reset Winsock, and flush DNS)。如果此操作无法解决问题,请继续执行下一个解决方案。
6]更新网卡驱动程序
过时(Obsolete)、损坏或损坏的网卡驱动程序可能会触发此错误。在这种情况下,为了排除这种可能性,您可以通过设备管理器(Device Manager)手动更新您的网络适配器驱动程序(update your network adapter drivers),或者您可以在Windows 更新下(Windows Update)的可选更新(get the driver updates on the Optional Updates)部分获取驱动程序更新。您也可以 从网卡硬件制造商的网站下载最新版本的驱动程序。(download the latest version of the driver)
7]禁用IP助手服务
此解决方案要求您禁用 IP Helper 服务(disable the IP Helper service)并查看手头的问题是否已解决。
8]将网络适配器设置为HT模式
HT 模式允许您指定支持高吞吐量(High Throughput)(802.11n) 和/或超高吞吐量(High Throughput)(802.11ac) 的模式。
此解决方案要求您在 Windows PC 上将网络适配器设置为 HT 模式。就是这样:
- 按 Windows key + R 调用“运行”对话框。
- 在“运行”对话框中,键入 ncpa.cpl 并按Enter以打开“网络连接(Network Connections)”控制面板。
- 接下来,右键单击您的活动网络适配器并选择Properties。
- 在属性窗口中,单击 配置 (Configure )按钮。
- 在网络适配器属性窗口中,单击高级(Advanced)选项卡。
- 在属性部分选择HT 模式。(HT mode)
- 单击确定(OK)。
- 退出网络连接(Network Connections)控制面板。
- 重启电脑。
检查您现在是否可以连接到网络;否则,请尝试下一个解决方案。
9]将IP(Set IP)和DNS地址设置为自动(Automatic)
请执行下列操作:
- 按 Windows key + R 调用“运行”对话框。
- 在“运行”对话框中,键入 ncpa.cpl 并按Enter以打开“网络连接(Network Connections)”控制面板。
- 接下来,右键单击您正在使用的网络连接,然后单击 Properties。
- 选择并双击 Internet Protocol Version 4 (TCP/IPv4) 选项以编辑其属性。
- 在 常规(General) 选项卡中,确保单选按钮设置为 自动获取 IP 地址(Obtain an IP address automatically) 和 自动获取 DNS 服务器地址(Obtain DNS server address automatically)。
- 单击 确定(OK) 以保存更改。
- 再次单击 确定退出(OK)网络连接(Network Connections)属性。
- 退出控制面板。
- 重启电脑。
如果您仍然无法使用IPv6协议连接到网络,请尝试下一个解决方案。
10]使用IPv4
如果本文中列出的解决方案都不适合您,您可以使用IPv4 ,因为IPv6无论如何都不是主流。要在Windows PC 上使用IPv4,您需要禁用 IPv6,然后您的系统将自动默认使用IPv4协议。
希望这些解决方案对您有所帮助!
IPv6 比 IPv4 快吗?
根据进行的测试,IPv4名列前茅。从理论上讲,IPv6可能比IPv4更快是基于这样一个事实,即不必在NAT转换上浪费周期。然而,IPv6也有更大的数据包,这可能会使某些用例的速度变慢——但随着时间的推移和微调,IPv6网络可能会成为事实上的协议,并且会变得更快。

Fix IPv6 Connectivity, No network access error on Windows 11/10
Some Windоws users may encounter the IPv6 Connectivity, No network access error when attempting to connect to a network on Windows 11 or Windows 10 computer. In this post, we identify the potential triggers, as well as provide the most adequate solutions to remediate the issue.
Why does IPv6 say No network access?
If you have encountered the IPv6 No internet access problem on your Windows PC, it’s most likely due to you’re using the wrong ethernet driver or it’s out of date or corrupted or damaged. In any case, to resolve the issue, update your ethernet network card drivers. The most likely culprits to this error include-
- Incorrect HT Mode settings.
- Obsolete network adapter drivers.
- Incorrect DNS and IP addresses.
- Third-party antivirus software.
Fix IPv6 Connectivity, No network access error
If you’re faced with this IPv6 Connectivity, No network access error, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.
- Restart PC and Internet device
- Temporarily disable third-party security software (if applicable)
- Uninstall VPN client (if applicable)
- Run Network Troubleshooter
- Release/Renew IP, reset Winsock and flush DNS
- Update Network card drivers
- Disable IP Helper service
- Set Network Adapter to HT mode

Let’s take a look at the description of the process involved concerning each of the listed solutions.
Before you try the solutions below, make sure IPv6 is enabled and also check for updates and install any available bits on your Windows device and see if the error reappears.
1] Restart PC and Internet device
Your first line of action in resolving theerror is to restart your PC as well as your internet device (modem/router).
2] Temporarily disable third-party security software (if applicable)
This solution requires you to disable, or better still uninstall any third-party security software installed on your Windows 10/11 PC, using the AV dedicated removal tool.
To disable your antivirus software, locate its icon in the notification area or system tray on the taskbar (usually in the lower right corner of the desktop). Right-click the icon and choose the option to disable or exit the program.
3] Uninstall VPN client (if applicable)
If you are actively connecting via a VPN on your Windows PC you may encounter this error. In this case, you can uninstall the VPN software and see if that helps resolve the issue.
4] Run Network Troubleshooter
This solution requires you to run the Network Troubleshooter to resolve any network-related issues on your Windows 11/10 computer.
5] Release/Renew IP, reset Winsock, and flush DNS
This solution requires you to release and renew IP, reset Winsock, and flush DNS. If this operation fails to resolve the issue, proceed with the next solution.
6] Update network card drivers
Obsolete, damaged or corrupted network card drivers can trigger this error. In this case, to rule out this possibility, you can update your network adapter drivers manually via the Device Manager, or you can get the driver updates on the Optional Updates section under Windows Update. You may also download the latest version of the driver from the network card hardware manufacturer’s website.
7] Disable IP Helper service
This solution requires you to disable the IP Helper service and see if the issue at hand is resolved.
8] Set Network Adapter to HT mode
HT mode allows you to specify which modes to support High Throughput (802.11n) and/or Very High Throughput (802.11ac).
This solution requires you to set the network adapter to HT mode on your Windows PC. Here’s how:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type ncpa.cpl and hit Enter to open Network Connections control panel.
- Next, right-click your active network adapter and select Properties.
- In the properties window, click Configure button.
- In the network adapter properties window, click Advanced tab.
- Select HT mode under Property section.
- Click OK.
- Exit Network Connections control panel.
- Restart PC.
Check if you can now connect to the network; otherwise, try the next solution.
9] Set IP and DNS address to Automatic
Do the following:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type ncpa.cpl and hit Enter to open Network Connections control panel.
- Next, right-click on the network connection you are using and click on Properties.
- Select and double-click the Internet Protocol Version 4 (TCP/IPv4) option to edit its properties.
- In the General tab, make sure the radio button is set to Obtain an IP address automatically and Obtain DNS server address automatically.
- Click OK to save the changes.
- Click OK again to exit Network Connections properties.
- Exit Control Panel.
- Restart PC.
If you’re still unable to connect to the network using the IPv6 protocol, try the next solution.
10] Use IPv4
If none of the listed solutions in this post has worked for you, you can use IPv4 since IPv6 is not mainstream anyways. To use IPv4 on your Windows PC, you need to disable IPv6 and then your system will automatically default to IPv4 protocol.
Hope these solutions help you!
Is IPv6 faster than IPv4?
Based on tests carried out, IPv4 comes out on top. In theory, that IPv6 could be faster than IPv4 is predicated on the fact that cycles don’t have to be wasted on NAT translations. However, IPv6 also has larger packets, which may make it slower for some use cases – but with time and fine-tuning, IPv6 networks might become the de-facto protocol and will get faster.
