I have been trying for hours now to activate the service for this modem. I followed all steps, download the app, set up the SSID, and it says that I successfully connected to the wireless gateway. When I go to the next page to login to the wireless gateway, an error message comes up saying “cannot connect to the wireless gateway.” When I try to click on the links for “Supported ARRIS devices” it just brings me to a blank page on this website. PLEASE HELP!!!
