I have replaced my windows installation with Ubuntu 12.04 on my HP notebook but now the wireless doesnt work. I can connect to the internet using an ethernet cable but thats it. The wireless button is also displaying amber but wont change to blue when pressed. Can anyone help me with this?

I suggest you take a look at this thread http://ubuntuforums.org/showthread.php?t=2194306 Entry #6 is probably what you are looking for.

This is apparently a common problem with HP. By removing the hp-wmi module as described in #6 your WiFi switch will probably work again.
