Why would you want to set up a guest network in your home? I would want to put up a guest network for many reasons. One reason being is I would want any one going through my personal files. If i have guest and he/she needs to use my computer, and say i have impropriety photos of myself, I would have to watch him/her to see what he/she is doing. Or I could log out of my account and log in the guest account and walk away.
