无线网络故障排除

执行最初的连接检查

In this step you will check some basic information about your wireless network connection. This is to make sure that your networking problem isn’t caused by a relatively simple issue, like the wireless connection being turned off, and to prepare for the next few troubleshooting steps.

  1. 确保您的笔记本没有连接有线网络连接。

  2. 如果您有外部无线适配器(如无线 USB 适配器或 PCMCIA 卡)，请确保已将其插入您计算机上的相应插槽中。

  3. 如果您的无线卡是内置的，确保无线网卡开关是打开的。笔记本一般可以通过按一个组合键来切换。

  4. Open the system menu from the right side of the top bar and select the Wi-Fi network, then select Wi-Fi Settings. Make sure that the Wi-Fi switch is set to on. You should also check that Airplane Mode is not switched on.

  5. Open the Terminal, type nmcli device and press Enter.

    This will display information about your network interfaces and connection status. Look down the list of information and see if there is an item related to the wireless network adapter. If the state is connected, it means that the adapter is working and connected to your wireless router.

如果您已连接到无线路由器，但仍无法访问网络，则您的路由器设置可能错误或互联网服务提供商 (ISP) 可能遇到了一些技术问题。请复核您的路由器和 ISP 安装指南，或与您的 ISP 联系以获取支持。
