This question already has an answer here:
I have a machine that I just installed Ubuntu Server on. The only problem is that I do not know how to connect it to a wireless network, and I cannot use a network cable to connect it to my router.
When trying to list the network cards, only the loopback interface showed up:
$ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric 1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
which was unexpected, as both my Ethernet network interface (
eth0) and wireless network interface (
wlan0) showed up when doing the same in a fresh installation of Ubuntu Desktop 10.10.
So, my two questions are:
- how can I install the wireless drivers (and packages I could download etc.) and/or set up the wireless network interface to work properly, and
- how can I connect to a WPA-encrypted wireless network from the command line?
I ended up uninstalling Ubuntu Server and installing Ubuntu Desktop instead, then configuring the wireless network through the GUI and making it boot into command line instead of GNOME.
