I have installed Ubuntu 11.10 on the Win 7 machine for the first time. I'm unaware of any commands.

I'm unable to connect the Internet using my laptop. I haven't tried using the wired connection.

It gives the error that 'Wireless firmware missing'.

What should I do ?

its worth rebooting, connecting via a wired connection, make sure you have working internet and then open the "additional drivers" window. You may have a wireless driver to activate. If you dont, please have a look at this Q&A and post some details by editing your question:… – fossfreedom Jan 14 '12 at 18:23

Do you know what make of a wireless card you have? I have this issue after every update, but this is a known issue with broadcom cards. If you have that card try this it works for me, unlike the Restricted Driver option
