Kind of strange.. Must be that Rogers isn't routing that IP address properly, I guess. Get yourself a different IP address, and see if that helps.
To get a new IP, option 1:
Change the MAC address of the equipment connected to the modem
Disconnect the coaxial cable and reboot modem. Go to »192.168.100.1
, click on Configuration and then Restore All Defaults, confirm. Click Reboot.
Either reconnect the coaxial to see, or wait for more than 30 minutes and then reconnect the coaxial.
Of course check the IP address to confirm it is different (hopefully a different default gateway too?).--
