<title>Thực hiện kiểm tra ban đầu</title>

<p>Bước đầu tiên là xác minh thông tin kết nối mạng cơ bản.</p>

<item><p>If you have an external wireless adapter (such as a wireless-USB adapter, or a PCMCIA card), make sure that it is inserted into the proper slot on your computer.</p></item>
31
<item><p>If your wireless card is <em>inside</em> of your computer, make sure that your wireless adapter switch is turned on.</p></item>
32
<item><p>In the <gui>Top Bar</gui>, make sure that you have not set the <gui>Wireless</gui> setting to <gui>Off</gui>.</p></item>
33
<item><p>Open a <app>terminal</app> window (such as <app>gnome-terminal</app>), and enter the following command:</p>
34
<p><cmd>nm-tool</cmd></p></item>
37
<p>The <app>nm-tool</app> program will display information about your network hardware and connection status. If output from the wireless connection section contains the text, <code>State: Connected</code>, it means that your wireless adapter is working and it is connected to your wireless router.</p>
39
<p>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, or contact your ISP for support.</p>
40
<p>If the output from the <cmd>nm-tool</cmd> command did not indicate that you were connected to the network, click <gui>Next</gui> to proceed to the next portion of the troubleshooting guide.</p>

23
<p>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.</p>

30
<p>If you have an external wireless adapter (such as a USB adapter, or a PCMCIA card that plugs into your laptop), make sure that it is firmly inserted into the proper slot on your computer.</p>
33
<p>If your wireless card is <em>inside</em> 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.</p>
36
<p>Click the network icon and make sure that <gui>Wireless</gui> is set to ON. You should also check that <link xref="net-wireless-airplane">Airplane Mode is not switched on</link>.</p>
39
<p>Open the Terminal, type <cmd>nm-tool</cmd> and press <key>Enter</key>.</p>
40
<p>This will display information about your network hardware and connection status. Look down the list of information and see if there is a section related to the wireless network adapter. The information for each network device is separated by a row of dashes. If you find the line <code>State: Connected</code> in the section for your wireless adapter, it means that it is working and connected to your wireless router.</p>
44
<p>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.</p>
46
<p>If the information from <cmd>nm-tool</cmd> did not indicate that you were connected to the network, click <gui>Next</gui> to proceed to the next portion of the troubleshooting guide.</p>
