Windows PC上的“无法更新 IP 地址”错误是由于与其他设备的 IP 冲突、Windows网络设置问题或网络适配器或路由器问题。如果您在Windows(Windows)中收到“无法更新 IP 地址”错误，您可以尝试执行一些步骤来排除故障并解决问题。
在大多数情况下，运行Windows 网络诊断(Windows Network Diagnostics)工具应该可以解决网络连接的任何问题。如果它不起作用，您需要打开Windows命令行或PowerShell窗口并按照这些说明进行操作。您还应该仔细检查您的网络设备是否正常工作。
运行 Windows 网络诊断工具(Run The Windows Network Diagnostics Tool)
有时，您的 PC 会遇到网络连接问题。Windows 网络诊断(Windows Network Diagnostics)工具可帮助您自动解决大多数此类问题。
- 要运行Windows 网络诊断(Windows Network Diagnostics)工具，请右键单击Windows任务栏中的网络图标。单击(Click) 网络问题(Network Problems)开始。
Windows 将对您的网络配置和设备进行初始扫描，以检查它是否可以自动识别任何潜在问题。如果可以，它会通知您问题并询问您是否自动修复它。
Windows可能会在此阶段诊断“无法更新 IP 地址”错误的原因。允许Windows自动修复问题，如果不能，请尝试其他方法。
释放和更新您的 IP 地址(Release & Renew Your IP Address)
当您连接到网络时，您的 PC 通常会在有限的时间内由路由器分配一个 IP 地址。这些被称为 IP 的“租约”一次最多可以持续 24 小时。
大多数情况下，您的网络路由器会一次又一次地分配相同的 IP 地址，但偶尔也会发生冲突。IP 地址可能会意外分配给另一台设备，或者由于配置错误或硬件问题，您的网络适配器可能难以完成 IP 租约续订过程。
如果您的 Windows 机器显示“无法更新 IP 地址”错误，并且Windows 网络(Windows Network) 诊断(Diagnostics)工具无法解决问题，您应该尝试使用 ipconfig 工具自动释放和更新您的 IP 地址租约。(release and renew your IP address)
- 打开一个Windows PowerShell窗口开始。为此，请右键单击任务栏上的Windows 开始(Windows Start)菜单按钮，然后单击Windows PowerShell (Admin)。您还可以使用较旧的Windows命令行来执行这些操作。
如果您的菜单显示命令提示符(Command Prompt)，请阅读上一篇关于如何将菜单项切换到 PowerShell 的(switch the menu items to PowerShell)文章。
- 要查看当前网络配置详细信息的列表，请键入ipconfig /all。
- 要释放您的 IP 地址，请键入ipconfig /release。这将从任何分配的 IP 地址中释放您的网络适配器。
- 释放网络适配器后，键入ipconfg /renew以分配新的 IP 地址租约。
在大多数情况下，强制释放和更新 IP 租约应该可以解决 IP 地址错误，但如果没有，您将需要查看更激进的选项，例如重置Windows网络配置。
重置您的 Windows 网络配置(Reset Your Windows Network Configuration)
如果网络连接仍有问题，重置网络设置可以解决问题。您可以从命令行或Windows PowerShell窗口执行此操作。
- 右键单击任务栏上的 Windows 开始菜单按钮，然后单击Windows PowerShell（管理员）(Windows PowerShell (Admin) )以打开PowerShell窗口。如果您愿意，可以使用较旧的Windows命令行。(Windows)
Winsock是Windows网络基础架构的一部分，旨在帮助Windows PC(PCs)及其上运行的软件通过标准网络进行通信。您的Winsock设置有时可能会被防病毒软件或恶意软件恶意损坏。重置Winsock设置可以解决此问题。
- 在Windows PowerShell或命令行中，键入netsh winsock reset。该过程完成后，系统会要求您重新启动 PC。
netsh （网络外壳）工具是(netsh)Windows上网络命令的低级管理工具。您可以使用它来重置TCP/IP设置。这可以通过删除任何冲突的设置或连接来解决“无法解析 IP 地址”问题。
- 键入netsh int ip reset以重置您的TCP/IP设置。完成后，重新启动 PC 以完成该过程。
最后，您可以从Windows(Windows)网络设置菜单执行完整的网络重置。这将彻底清除您的所有网络配置设置。例如，如果您已将网络适配器设置为使用静态 IP 地址，这将删除这些设置并将您的适配器重置为使用Windows的默认设置。
- 打开Windows设置菜单。为此，请右键单击任务栏上的Windows 开始(Windows Start)菜单按钮，然后单击设置(Settings)。
- 单击网络和 Internet(Network & Internet)进入您的Windows网络设置菜单。
- 单击左侧菜单中的状态。(Status)从这里，滚动到更改您的网络设置(Change your network settings)类别，然后单击网络重置。(Network reset.)
- 在网络重置(Network Reset)菜单中，单击立即重置(Reset Now)按钮。
- Windows 将询问您是否要继续进行网络重置。单击(Click) “是”(Yes)开始该过程。该过程完成后， Windows(Windows)将完全重置您的网络配置并重新启动您的 PC。
使用上述方法重置网络配置会耗尽解决Windows(Windows)本身“无法更新 IP 地址”问题的选项。如果问题仍然存在，则原因可能是您的网络设备出现问题。
排除网络设备故障(Troubleshoot Your Network Devices)
如果您无法解决Windows上的网络连接问题，请改为对网络设备进行故障排除。
如果您使用的是有线网络，请仔细检查您的有线连接。检查您的以太网电缆是否连接正确，如果连接正确，请关闭电缆。
尝试使用另一个网络适配器来仔细检查您是否能够连接到您的网络。如果失败，请连接到备用网络以查看故障是否是由于网络路由器的问题引起的。
How to Fix “Cannot renew IP address” in Windows
A ‘cannot renew IP address’ error оn your Windows PC is due to an IP confliсt with another device, issues with your Windows nеtwork settingѕ, or a problem with your network adаpter or router. If you gеt a ‘cannot renew IP address’ error іn Windows, therе are a few steps you can try to troubleshoot and resolve the problem.
In most cases, running the Windows Network Diagnostics tool should fix any issues with your network connection. If it doesn’t work, you’ll need to open a Windows command line or PowerShell window and follow these instructions. You should also double-check your network devices are working correctly, too.
Run The Windows Network Diagnostics Tool
From time to time, your PC will run into issues with your network connection. The Windows Network Diagnostics tool exists to help you resolve most of these issues automatically.
- To run the Windows Network Diagnostics tool, right-click on your network icon in the Windows taskbar. Click Network Problems to begin.
Windows will make an initial scan of your network configuration and devices to check whether it can automatically identify any potential problems. If it can, it’ll inform you of the problem and ask you whether to automatically fix it or not.
Windows will likely diagnose the cause of a ‘cannot renew IP address’ error at this stage. Allow Windows to automatically fix the problem and, if it can’t, try another method instead.
Release & Renew Your IP Address
When you’re connected to a network, your PC is usually issued an IP address for a limited amount of time by your router. These IP “leases”, as they’re called, will last for up to 24 hours at a time.
Most of the time, your network router will assign this same IP address again and again but, occasionally, conflicts can occur. The IP address might be assigned to another device by accident or your network adapter may struggle to complete the IP lease renewal process due to a bad configuration or hardware issue.
If your Windows machine displays the ‘cannot renew IP address’ error, and the Windows Network Diagnostics tool can’t fix the problem, you should attempt to release and renew your IP address lease automatically using the ipconfig tool.
- Open up a Windows PowerShell window to begin. To do that, right-click your Windows Start menu button on the taskbar, then click Windows PowerShell (Admin). You can also perform these actions using the older Windows command line.
If your menu is showing the Command Prompt, read out previous post on how to switch the menu items to PowerShell.
- To see a list of your current network configuration details, type ipconfig /all.
- To release your IP address, type ipconfig /release. This will release your network adapters from any assigned IP addresses.
- Once your network adapters are released, type ipconfg /renew to assign new IP address leases.
Forcefully releasing and renewing IP leases should resolve an IP address error in most cases but, if it doesn’t, you’ll need to look at more drastic options like resetting your Windows network configuration.
Reset Your Windows Network Configuration
If you’re still having trouble with your network connection, resetting your network settings can resolve the issue. You can do this from a command line or Windows PowerShell window.
- Right-click your Windows Start menu button on the taskbar, then click Windows PowerShell (Admin) to open a PowerShell window. You can use the older Windows command line if you’d prefer.
Winsock is a part of the Windows network infrastructure, designed to help Windows PCs and the software running on them to communicate over standard networks. Your Winsock settings can sometimes be corrupted accidentally by antivirus software or maliciously by malware. Resetting your Winsock settings can resolve this.
- At the Windows PowerShell or command line, type netsh winsock reset. You’ll be asked to restart your PC once the process is complete.
The netsh (network shell) tool is the low-level administration tool for network commands on Windows. You can use this to reset your TCP/IP settings. This can resolve the ‘cannot resolve IP address’ issue by removing any conflicting settings or connections.
- Type netsh int ip reset to reset your TCP/IP settings. Once completed, restart your PC to finish the process.
Finally, you can perform a full network reset from the Windows network settings menu. This will completely wipe all of your network configuration settings. If, for instance, you’ve set your network adapter to use a static IP address, this will remove those settings and reset your adapter to use Windows’ default settings instead.
- Open your Windows settings menu. To do this, right-click the Windows Start menu button on your taskbar, then click Settings.
- Click Network & Internet to enter your Windows network settings menu.
- Click Status from the left-hand menu. From here, scroll to the Change your network settings category, then click Network reset.
- In the Network Reset menu, click the Reset Now button.
- Windows will ask you if you want to proceed with the network reset. Click Yes to begin the process. Windows will reset your network configuration completely and restart your PC once the process has finished.
Resetting your network configuration using the above methods exhausts the options for resolving a ‘cannot renew IP address’ issue on Windows itself. If the problem persists, the cause is likely due to a problem with your network devices.
Troubleshoot Your Network Devices
If you’re unable to resolve issues with your network connection on Windows, troubleshoot your network devices instead.
If you’re on a wired network, double-check your wired connections. Check that your ethernet cables are connected correctly and if they are, switch out the cables.
Try another network adapter to double-check whether you’re able to make a connection to your network. If that fails, connect to an alternative network to see whether the fault is due to an issue with your network router instead.
