[lubuntu] wifi dongle drivers

Hi everyone,
I've been having problems with my old wifi dongle (getting online but zero Mbps speed), so I bought a new one. However, the Linux drivers for the new dongle are on a CD Rom and don't show up in additional drivers and being a novice all my attempts have thus far failed.

So, my question is how to I install drivers from a CD Rom?


Many thanks

Kev

P.S.

When I type:

cd /media/cdrom#

into the terminal it replies with:

bash: cd: /media/cdrom#: No such file or directory
