Business WiFi Pro allows you to create Private WiFi and Guest WiFi networks from within the WiFi Pro Router. Once you create a network, you can configure SSID scheduling, bandwidth management, content filtering and a landing page.
If you offer patients a WiFi network to access when they are in your office waiting room, your practice is liable for any criminal activity that transpires. Considering that nothing on the internet is really secret, this is a serious concern.
You may provide a 'splash page' containing an acceptable use policy, but those are seldom read and even more seldom followed. Your acceptable use policy cannot effectively limit your office's liability. If someone uses your WiFi network for criminal activity, and the activity is tracked, your practice is on the hook.
