I don't have a stream of random people, but even giving even a good friend access to my network, who really knows where he travels on the internet? Apparently something as innocent sounding as coupons can results in downloading malware. Can the Guest SSID be hidden? If a guest network is just the same as another network in another house, then I think I'll set one up.But I don't have a constant stream of random people showing up to use my wifi. So, use guest network according to one's solution. But I think there's a lot of simplicity and no real risk to just giving friends and family your network password.
