i work in tech support and i am an advanced windows user. but i have not used linux other than booting up live cd's and checking out the applications. i have recently installed centos 4.5 on a computer for testing. all my hardware installed with good defaults and i have been able to access the internet for updates. but that is as far as i have been unable to get. i want to install a wireless card and download and install some additional software and setup window shares but i do not know where to start. i have found some software in tar and rpm file extentions but i need help downloading them, extracting or installing them. my wireless card is not recognized. also i have found alot of rpm files in red hat and fedora but i do not know if they will work with centos. i know centos is built from red hat but what version of red hat or fedora would it be equal to so the right software or driver would be installed. this is just a testing computer and i just started working with it and do not need it for anything else so i have plenty of time to learn and become an advanced linux user.
thanks
