building a 2nd computer in my house for my upstairs bedroom. i want to network my two computers together. i have comcast cable internet and am not sure which way is the best. all i want to do is share internet access and files and printer access. the computers are separated by two floors and was wondering what would be better, wired or wireless networking? really confused on which one would be better, since they all have their pros and cons. im pretty positive i won't be getting a 3rd computer. heard about crossover cables but don't like it cuz both computers have to be on. so what would you guys suggest, wireless or wired connection? thanks for any help.
