無線網路故障排除

進行初步檢查

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. 確保您的筆記型電腦並未連接「有線網路」。

  2. 若您擁有外接網卡（如 USB 網卡或 PC 卡網卡），請將其確實接在電腦上對應的介面。

  3. If your wireless card is inside your computer, make sure that the wireless switch is turned on (if it has one). Laptops often have wireless switches that you can toggle by pressing a combination of keyboard keys.

  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. 啟動《主控臺》並輸入「nmcli device」，輸入完後按下Enter執行。

    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.

If you are connected to your wireless router, but you still cannot access the internet, your router may not be set up correctly, or your Internet Service Provider (ISP) maybe experiencing some technical problems. Review your router and ISP setup guides to make sure the settings are correct, or contact your ISP for support.

If the information from nmcli device did not indicate that you were connected to the network, click Next to proceed to the next portion of the troubleshooting guide.
