I'm trying to figure out how I can setup two separate networks on a Westell 327w modem/router. I know this question has been asked to death and I've utilized the search function, but I still don't know how to make this work. I have a computer that I plan on using for important business and my sibiling has my other computer that he uses for gaming and downloading stuff. His computer is connected wirelessly to the Westell 327w. My computer has no internet access at this point. I would like to have both connected wirelessly to the internet, but keep them completely separate and as secure as possible, as he downloads some questionable things. Can someone let me know what I will need and how to do this? Also I have a Westell C90 modem/router laying around here somewhere and I'm wondering if it can be used in this situation.
