Man I've just Install Ubuntu Studio but I didnt find how to makes my wLAN connection active.. maybe any of you would share here.. ? Thanks before..

I've used to have Linux Mint and Ubuntu installed on my laptop before. I didn't have any issues setting up the wireless though. It seemed to work. I haven't used Ubuntu Studio before, but a quick google might turn up some good results on how to resolve it. Make sure you have the wireless button switched on on your laptop.

i have an ubuntu cd somewhere, but i havent tried it on much, apart for some stuff we did as practising in school and then my net worked just fine

so sorry, cant really add much to what mark wrote

No "offence", this stuff should be googled.
