I installed Ubuntu 12.10 32-bit on my MSI fx600 laptop, which has Intel link 1000 b-g-n wireless card. I am not able to connect to any wireless networks. Ubuntu is able to find Wi-Fi networks around me, but I am not able to connect to any of them.
What should I do? Could you please be specific, because I have never used any Linux distributions before and this is very confusing for me.
