I am currently multibooting Xp and Ubuntu. I cannot connect to my Universities Public and Private wifi. The private is secure, but I have the info to access it. I've notice I can only connect to the wifi on XP, but when I run Ubuntu I'm getting nothing. If it helps I have a Intel Pro/Wireless 3945ABG wireless card.

You need to make sure to install the drivers for the wireless card. Does you computer have a Wi-Fi indicator "light"? If so, can you turn it on or off while in Ubuntu?

Also, please post as much hardware information that you can and version of Ubuntu you are using.

Can you post the output of


lshw -C Network

when run from a terminal in ubuntu? This will display what networking hardware you have installed and may give a clue as to what the problem is.

I have the same wireless adapter and just couldn't get it to work with Network Manager.

The cure for me was to remove the network-manager package with Synaptic and install Wicd (http://wicd.sourceforge.net/).

Could you give me steps on how to do this?

That card should work fine, you might be affected by this:

A few questions:
Have updated since you installed?
Is there a light that's on when using Windows but not Ubuntu?
What's the output of BDNiner's command?

Wicd might be a good solution, but I'd say that's a last resort since it should work.

+1 to the poster who suggested wicd. NetworkManager did the same thing with my atheros5k and my enlwig2 (rtl8185 based) card. The networks were there but would never connect to them. Now i use wicd instead and both cards work fine.

The light is on when I use both Ubuntu and Windows, how do I uninstall network manager and install wicd? I've already updated. Sorry I just install this yesterday. I am still a noob. :(

Probably the easiest suggestion is the Ubuntu section of their site:
http://wicd.sourceforge.net/download.php

Administration > Synaptic Packages
add this to the third party tab:
deb http://apt.wicd.net intrepid extras

Now in a terminal window type:
wget -q http://apt.wicd.net/wicd.gpg -O- | sudo apt-key add -

Now in add remove programs search for wicd

If you have any problems just post back

To remove the Network Manager, go to "Applications", and then select "Add/Remove...", type "network" in the search bar and un-check "Network Manager", finish by clicking on "Apply Changes".

Ubuntu is detecting your card fine. I am not sure about installing wicd so someone with experience should chime in this issue.

Then reload.
