can majicjack use a wifi enabled desktop computer and wired phone to connect to the internet as opposed to a wired router which I do not use? I use wifi only for computer.
I would recommend that you follow their official suggestions on installation (How do I set-up/connect magicJack? | Frequently Asked Questions ) for best operations. You'll need to have 1 spare Ethernet port on your router for connection of your device.
Depends which MagicJack you have.. The really old ones would use a USB port on a computer.
If you have Shaw internet, even if your computer uses WiFi, there should still be a modem/router around there with Ethernet ports.
