最后一行显示我的无线网卡驱动名称是iwl3945（intel 3945abg无线网卡），将它加入到黑名单就可以了，具体操作如下：</li>
<li>
sudo gedit /etc/modprobe.d/blacklist.conf</li>
<li>
在文本最后加入 blacklist iwl3945</li>
<li>
重新启动</li>
<li>
如果的确长时间不会用到无线网络，这个方法就比较干净彻底。</li>

如果学习了<font color="#0068b4">配置interfaces文件</font>，也可以完全抛开NetworkManager，更加灵活地控制网络设定。现在也渐渐能体会到Linux将配置文件全部写成文本文档的优点所在了。</p>
