<p class="p">In this step you will check some basic information about your wireless
89
network connection. This is to make sure that your networking problem isn’t
90
caused by a relatively simple issue, like the wireless connection being
91
turned off, and to prepare for the next few troubleshooting steps.</p>
92
<div class="steps"><div class="inner"><div class="region"><ol class="steps">
93
<li class="steps"><p class="p">Make sure that your laptop is not connected to a <span class="em">wired</span>
94
internet connection.</p></li>
95
<li class="steps"><p class="p">If you have an external wireless adapter (such as a USB adapter, or a
96
PCMCIA card that plugs into your laptop), make sure that it is firmly
97
inserted into the proper slot on your computer.</p></li>
98
<li class="steps"><p class="p">If your wireless card is <span class="em">inside</span> your computer, make sure that
99
the wireless switch is turned on (if it has one). Laptops often have
100
wireless switches that you can toggle by pressing a combination of
101
keyboard keys.</p></li>
102
<li class="steps"><p class="p">Open the
103
<span class="gui"><a href="shell-introduction.html.tr#systemmenu" title="System menu">system menu</a></span> from the right
104
side of the top bar and select the Wi-Fi network, then select <span class="gui">Wi-Fi
105
Settings</span>. Make sure that the <span class="gui">Wi-Fi</span> switch is set to on.
106
You should also check that <span class="link"><a href="net-wireless-airplane.html.tr" title="Turn off wireless (airplane mode)">Airplane
107
Mode</a></span> is <span class="em">not</span> switched on.</p></li>

110
<span class="key"><kbd>Enter</kbd></span>.</p>
111
<p class="p">This will display information about your network interfaces and
112
connection status. Look down the list of information and see if there is
113
an item related to the wireless network adapter. If the state is
114
<span class="code">connected</span>, it means that the adapter is working and connected
115
to your wireless router.</p>
117
</ol></div></div></div>
118
<p class="p">If you are connected to your wireless router, but you still cannot access
119
the internet, your router may not be set up correctly, or your Internet
120
Service Provider (ISP) maybe experiencing some technical problems. Review
121
your router and ISP setup guides to make sure the settings are correct, or
122
contact your ISP for support.</p>
123
<p class="p">If the information from <span class="cmd">nmcli device</span> did not indicate that you were
124
connected to the network, click <span class="gui">Next</span> to proceed to the next
125
portion of the troubleshooting guide.</p>
