Ubuntu Server 14.04.4 Wireless card not enabled, Wlan0 port not found

Ubuntu Server default is not to enable the wireless network card, think of how the actual server can have wireless network card, hehe. So we need to manually enable the wireless card, the difficulty is here.

Using the Ifconfig command, it is found that there is no WLAN port, but using

1. Sudo lshw-numeric-class network
2. Sudo ifconfig-a

Can find Wlan0 port, in fact, Ubuntu server is not enabled by default wireless network card, only need to change the configuration file to enable the wireless card.

3, set up the wireless network. Edit the/etc/network/interfaces file to add the WLAN to it:

#vim/etc/network/interfaces

Add in the inside:

Auto Wlan0
Iface Wlan0 inet DHCP
Wpa-conf/etc/wpa_config.conf

Note If your router does not have DHCP turned on, you will need to manually configure the address, netmask, Gateway, network, and broadcast parameters, which is not much to say. The other is wpa-conf followed by the key configuration file name you just generated.

If you never need to use a wired network, you can disable it with a wired network, and comment out the auto eth0.

4. Restart the computer. according to my actual operation results, after the configuration, although the wireless network card is enabled, but the driver seems not loaded full. Therefore, you need to restart Ubuntu server to fully enable the wireless card.

At this point, Ubuntu server can also connect to the wireless router with a wireless network connection.
