Re: Wide open?
I know those modems. The guest network is fine and not actually open. A lot of hotspots appear open but use other authentication these days so WarKitteh is likely to be deceptive in stats. Generally Wi-Fi is reasonably likely to be secure when I've looked around lately, we're far from the heyday of wardriving. Usually if you want to crack a network Reaver is your only option, and most WPS schemes have protection built in against it now anyway.
An aside, those modems aren't Cisco. Most Rogers hardware is from Hitron. The current "state of the art" modem they're pushing everyone to is a Hitron CGN3.
