DaveTheBrave asks: "I'm currently running a home based business on an el cheapo Netgear wireless router off a broadband cable modem connection. I'm looking to upgrade to something better with more flexibility. My in-laws recently sold their home and will be moving into my home temporarily while they are building another. They have a home based business and my mother-in-law is also notorious for attracting viruses, adware and other nasty stuff on her PC (which I have to routinely clean - hence my need for a better network solution). What is the best/easiest solution to segment and keep separate my network from theirs (both wired and wireless) off of one incoming cable modem? I'm looking for something around or less than $500."
