重置 iPhone 的网络设置是解决各种连接问题的有效方法，例如网速慢(slow internet speeds)、蓝牙问题(Bluetooth problems)以及WiFi(complications with WiFi)或蜂窝数据的(cellular data)复杂问题。这是在执行其他适用的故障排除方法后必须采取的最后手段。
在本教程中，我们将教您如何将 iPhone 上的网络设置重置为出厂默认设置，以及之后必须如何重新配置设备。
如何在 iPhone 上
恢复出厂设置网络设置(Factory Reset Network Settings)
iPhone 网络设置重置会擦除之前加入的所有 Wi-Fi 网络和密码(previously-joined Wi-Fi networks and passwords)、删除自定义APN（接入点名称）和VPN设置，并将其他网络配置恢复为默认值。这有助于解决损坏的设置和其他可能导致网络和连接问题的潜在问题。
要重置 iPhone 上的网络设置，您必须：
- 打开iOS 设备上的
“设置”应用程序。(Settings)
- 点击常规类别。
- 向下滚动(Scroll)并点击“传输”(Transfer)或“重置(Reset)iPhone”。
- 点击重置。
- 选择重置网络设置(Reset Network Settings)选项。
- 输入您的 iPhone 密码。如果您在 iPhone 上设置了“屏幕使用时间”(Screen Time set up on your iPhone)，则必须输入“屏幕使用时间”密码(Screen Time passcode)。
- (Tap Reset Network Settings)在确认弹出窗口中
点击重置网络设置。
屏幕应变暗，并立即出现Apple徽标和进度指示器。完成后，您的 iPhone 会自动重新启动。输入您的设备密码以重新访问主屏幕(Home Screen)。
网络设置重置(Network Settings Reset)后会发生什么
在 iPhone 上重置网络设置后，您应该执行以下几项操作才能正常使用该设备。
蜂窝网络
您的 iPhone 会自动连接到运营商的网络，您应该能够毫无问题地拨打电话和使用移动数据。如果您使用自定义APN设置，请转至Settings > Cellular > Cellular Data以重新应用它们。如果您需要帮助，请联系您的运营商。
无线上网
与蜂窝数据不同，您的 iPhone 不会自动重新连接到Wi-Fi。相反，请转至Settings > Wi-Fi，点击无线连接，然后输入网络密码以重新加入。
蓝牙
您的 iPhone 会记住已配对的蓝牙(Bluetooth)设备，因此您可以在网络设置重置后立即连接并使用它们。如果您在执行此操作时遇到困难，请转至Settings > Bluetooth，忘记有问题的设备，然后从头开始配对。
iPhone名称
您的 iPhone 名称更改为“iPhone”，这可能会在其他设备上造成识别问题。要重命名您的 iPhone(rename your iPhone)，请前往Settings > General > “关于” > Name。
个人热点
iPhone 网络设置重置会禁用个人热点(Personal Hotspot)。转至General > Personal Hotspot以重新激活该功能并设置自定义密码。
VPN 配置
如果您使用自定义VPN配置，请转到Settings > General > VPN和Device Management > VPN，然后再次指定您的设置和首选项。

网络问题(Network Problems)
正如您刚刚发现的，重置 iPhone 的网络设置是一个相对简单的过程，并且在此过程中您不会丢失应用程序或个人数据。在采取更激进的技术（例如将整个 iPhone 恢复至出厂设置）(restoring your entire iPhone to its factory settings)之前，请先尝试此方法。
How to Reset Your iPhone’s Network Settings
Resetting yoυr iPhone’s network settings is an effectiνе way to fіx various connectivity issues, such as slow internet speeds, Bluetooth problems, and complications with WiFi or cellular data. It’s a last-resort measure you must undertake after you’ve gone through other applicable troubleshooting methods.
In this tutorial, we’ll teach you how to reset the network settings on your iPhone to factory defaults and what you must do to reconfigure the device after that.
How to Factory Reset Network Settings on iPhone
An iPhone network settings reset erases all previously-joined Wi-Fi networks and passwords, removes custom APN (access point name) and VPN settings, and restores other network configurations to default values. This helps resolve corrupt settings and other underlying problems that could be causing network and connectivity issues.
To reset the network settings on an iPhone, you must:
- Open the Settings app on your iOS device.
- Tap the General category.
- Scroll down and tap Transfer or Reset iPhone.
- Tap Reset.
- Select the Reset Network Settings option.
- Enter your iPhone passcode. If you have Screen Time set up on your iPhone, you must follow up with your Screen Time passcode.
- Tap Reset Network Settings on the confirmation pop-up.
The screen should darken, and an Apple logo and a progress indicator should immediately follow. Once it reaches the end, your iPhone automatically restarts. Enter your device passcode to regain access to the Home Screen.
What Happens After a Network Settings Reset
After performing a network settings reset on your iPhone, here are several things you should do to use the device normally.
Cellular
Your iPhone automatically connects to your carrier’s network, and you should be able to make calls and use mobile data without issues. If you use custom APN settings, go to Settings > Cellular > Cellular Data to re-apply them. Contact your carrier if you need help.
Wi-Fi
Unlike cellular data, your iPhone won’t reconnect to Wi-Fi automatically. Instead, go to Settings > Wi-Fi, tap a wireless connection, and enter the network password to rejoin it.
Bluetooth
Your iPhone remembers paired Bluetooth devices, so you can connect and use them right after the network settings reset. If you have trouble doing that, go to Settings > Bluetooth, forget the device in question, and pair it from scratch.
iPhone Name
Your iPhone’s name changes to “iPhone,” which could create identification issues on other devices. To rename your iPhone, go to Settings > General > About > Name.
Personal Hotspot
An iPhone network settings reset disables Personal Hotspot. Go to General > Personal Hotspot to reactivate the feature and set up a custom password.
VPN Configurations
If you use a custom VPN configuration, go to Settings > General > VPN and Device Management > VPN, and specify your settings and preferences again.
Get Rid of Network Problems on iPhone
As you just found out, resetting your iPhone’s network settings is a relatively straightforward procedure, and you don’t lose apps or your personal data during the process. Try this method before resorting to more drastic techniques, like restoring your entire iPhone to its factory settings.
