I installed ubuntu12.10 on a win8 lappy. But the wireless does not seem to work. Here are some of the details that you might be interested in. So as of now my machine is in a state where I can't connect to the internet, however I have another machine that connects to internet.

Please let me know, what is wrong with my laptops wireless settings and how do I install drivers if any.

Below is some data that you might be interested in.

RaLink are pretty well known for working out of the box. I assume this is your built in wireless card. What kind of laptop is it? Need to find out what the wireless adapters is to find out about drivers.

As I can see from lspci log you have RT3290 chipset. I have checked Ubuntu driver located at drivers/net/wireless/rt2x00 and it doesn't support this chip. Could you please post here output of the following command?

dmesg | grep rt2

I recently has solved my problem with RT5392 chipset, but it was easier 'cos 5390 is supported and 5392 is close to 5390. You chipset may be supported on resent 3.7/3.8 kernel. Check out following thread, looks like the guy solved the problem
