I have a Linksys WR54GS router as my main router attached to the internet. I run a Bed & Breakfast and I give my guests free access to the internet via WiFi. My problem is, I also use that network for my business and personal computers and I am afraid that a tech savvy guest could hack into my files. I thought that if I connect a second WiFi router, I could set up a second network which my guests could use to access the web thru my main router. Does anyone have a clue if this is possible?
