    Did ubuntu automatically find the drivers? what is the output of iwconfig? if it shows wlan0 or something like that then you just need to use NetworkManager to set it up. – Matt Apr 30 '12 at 14:46

    Welcome to Ask Ubuntu! We need more hardware information to help you, can you look at this question and then edit your question adding the information? – Jorge Castro Apr 30 '12 at 22:01

Are you saying that you do have a wireless router working, and you intend to connect to the wireless network in Ubuntu 12.04? In this case you might want to check out the bar at the top of the screen; there is an icon, by clicking which you can see something like Enable Wireless Network. Make sure it's ticked and you should be able to find your network in that popup menu. Click on the network and follow the instructions!

  • my system came with 802.11 b/g wireless LAN. With Ubuntu 12.04 it does not work. I have a 1800 Series Acer that came with Windows XP – Cephas May 01 '12 at 01:17

Hit CTRL+ALT+t, then type this in:

lspci | grep -i network

Then highlight the resulting text, right-click, select copy, then paste it as a response here. This will show what type of wireless you have, and we can help getting it working from there.

Other things to check: 1.) Ensure your physical wireless switch is left in the on position when you start up. 2.) Plug in the Ethernet cable and try running the updates from the "Updates Available" menu item (4th down) on the on-screen power button in the upper r/h corner of the Ubuntu interface.
