I tried a 10.10 Live CD and a pop-up directed me to install a proprietary driver for my wifi card before I could browse. However, my only means for internet access is through my school's wireless access point. What do I do now, since I can't install the driver for the card, and the same card doesn't allow me to connect to the wireless network? This is an Intel wireless card.
If you know which package you need (probably firmware-iwlwifi) you can download and install it seperately.
You mention the use of the live cd, so what exactly are you after?
