The best and fastest way to setup your new rogers modem is to use the provided flash drive that came with the package. That flash drive contains the setup files needed to install the settings required to start using the modem. You would need to choose a new network name (SSID), new security keys and that's about all needed to get started. Once setup is done, in order to access the new network, you need to enter the new network name or security keys on the device, you want to use (Cell Phone, Tablet, Laptop, Desktop).
You might need to initially use an Ethernet cable and connect it from your rogers modem to a laptop to do the setup. After that, you won't need the Ethernet cable anymore and you can connect using the rogers in built Wi-Fi modem.
