I daisy chain in my own router, then MAC address filtering. Turn off wifi on the Rogers router. If you are not home during the day you can possibly programmatically turn off wifi. The MAC address filtering is a bit of work to maintain, as you need all device MAC addresses, but I've gotten used to it.
You can also look into using metal mesh/aluminium foil to limit your router's directionality. For example if you are in an apartment and the router is on the west perimiter, put up some chicken wire blocking access further west. If you are in an apartment with a single floor then reorient your antenna to not transmit your signal higher or lower than your floor. That will further limit access.
