Hey. I just formatted a Dell n5010 and installed Ubuntu 10.04. Now,when i try to access the Internet it doesn't find the available networks.

Informations about it:

• My network is set to broadcast SSID;
• Already typed lspci, and it doesnt returns my wireless card;
• Tried installing windows drivers from fabricant cd usind diswrapper, but it says it cant complete the installation because it cant find some "Device" folder;

I don't know what else to do, I switch the wireless button on/off and it just can't see any wireless connection, includin mine.

Here are the informations about lspci:
