Add a wifi router noted at about post 18 in this forum and set it to WPA security and change the password every month if you feel like it.
I am attempting to find the most cost-effective way to provide wireless capability for our guests at a seven room B&B via our current high-speed modem. We are looking for something relatively simple, yet secure, where we can provide our guests a temporary password to enable them to access our connection via their laptops/notebooks during their stays with us.
Router model TBD after gathering additional info
Thanks to any of you who might be able to provide us some assistance.
