I logged into the GUI/admin for our Arcadyan modem (192.168.) a day later. We recently set up a brand new iPad (not refurbished) a few days ago and connected it to our guest network. MAC Address filter is also on and set to accept only our devices. We currently have Telus Internet and use their Arcadyan modem (tall white box) with our guest wifi network turned on. My concern is if someone is hacking into our network through our iPad (believe it's called a 'virtual handshake'). I'm new to this forum and want to first thank you folks in advance for providing feedback to my concern.
