I spent a couple of days trying to figure out why I could not connect to my wifi connection running 12.04.1 Server but installing 12.04.1 Desktop connects just fine, what am I missing here?

It's the same machine:

When Server is installed I can not see the wifi card when executing


But I do see it's DISABLED when executing

lshw -C network

*-network DISABLED
   description: Wireless interface

Running Desktop I navigate to Network and I'm able to see and connect to my wifi connection.

Why would this not work for Server? I really don't need the Desktop and I wanted to install server and be done with it but I would really like to know why doesn't the Server installation see / connect to my wifi?

BTW: I tried everything to enable wifi and connect to my network with server and nothing worked.

Could be because servers usually have no use for wifi connections. The Ubuntu server edition most certainly lacks the network manager, and might also lack the wireless modules and firmware. Do you have, for example /lib/firmware? What does dmesg | grep wlan0 have to say? – mikewhatever Feb 22 '13 at 0:22
@mikewhatever Im running the desktop version now and I see a bunch of authentication messages when running this command: dmesg | grep wlan0 – Phill Pafford Feb 22 '13 at 2:04
...and I assume that wireless works well, does it not? – mikewhatever Feb 22 '13 at 19:21
for the Desktop version yes, for the Server version No! – Phill Pafford Feb 22 '13 at 20:14
...and that is expected, as explained above. – mikewhatever Feb 22 '13 at 20:42
