mac 不能連接wi-fi

Your Mac automatically reconnects to Wi-Fi networks you’ve previously connected to. Starting with macOS High Sierra, you can now tell your Mac not to automatically connect to certain Wi-FI networks. Your Mac will remember the Wi-Fi network’s passphrase and other connection details, but won’t connect unless you tell it to.

您的Mac會自動重新連接到您之前連接的Wi-Fi網絡。 從macOS High Sierra開始，您現在可以告訴Mac不要自動連接到某些Wi-FI網絡。 您的Mac會記住Wi-Fi網絡的密碼短語和其他連接詳細信息，但是除非您告知，否則不會連接。

This is useful for Wi-Fi networks you may use occasionally, like Comcast’s xfinitywifi or other public Wi-Fi networks. On older versions of macOS, you had to delete a saved Wi-Fi network and its passphrase to stop the automatic connection from occurring.

這對于您可能偶爾使用的Wi-Fi網絡很有用，例如Comcast的xfinitywifi或其他公共Wi-Fi網絡。 在舊版本的macOS上，您必須刪除已保存的Wi-Fi網絡及其密碼，才能停止自動連接。

First, open the System Preferences window by clicking Apple menu > System Preferences.

首先，通過單擊Apple菜單>系統偏好設置來打開“系統偏好設置”窗口。

Click the “Network” icon in the System Preferences window.

單擊系統偏好設置窗口中的“網絡”圖標。

Select the “Wi-Fi” option in the left pane and choose the Wi-Fi network you want to modify from the Network Name box.

在左窗格中選擇“ Wi-Fi”選項，然后從“網絡名稱”框中選擇要修改的Wi-Fi網絡。

Uncheck “Automatically join this network” and your Mac won’t automatically join the Wi-Fi network in the future.

取消選中“自動加入此網絡”，您的Mac將來將不會自動加入Wi-Fi網絡。

You can also set the order of your Wi-Fi networks to tell your Mac to prefer certain Wi-Fi networks over other ones. Your Mac will try to connect to available Wi-Fi networks in the order you choose, preferring the ones at the top of the list.

您還可以設置Wi-Fi網絡的順序，以告知Mac與其他Wi-Fi網絡相比，它們更喜歡某些Wi-Fi網絡。 您的Mac將嘗試按您選擇的順序連接到可用的Wi-Fi網絡，而不是列表頂部的那些。
