View Full Version : [ubuntu] *-network DISABLED

Hi Ubuntu Gurus,

Thanks in advance for your help. I have used Linux and/or Ubuntu for about 3 hours total in my life. I installed Ubuntu on my laptop and I am now trying to get my wireless network card working.

After typing "command lshw -C Network" I get the following output:

Why is my "wireless interface" network marked as DISABLED?
How do I enable it?

Why not use the GUI? In the upper right bar: what does the network icon say? What can you do when you right click on that icon?

And: the wifi switch is on, right?

Just a guess, but it might be a driver issue - what chipset is in the machine?

Here are several methods--see posts 3 and later. One depends on having wired connection and the other if no wired is available.

Thanks all for your responses.

Hi sanderj: in the upper right bar, the wireless network icon has the red exclamation mark, indicating that it is not connected. After right-clicking the upper-right network icon, everything is checked as it should be.

Hi bkratz: Enabling the driver via System, Administration, Hardware Drivers seems to have worked.

Thanks again.
