I have a wide selection of cable modems that will work perfectly on any cable provider in Rogers territory. That includes Acanac, Start, and Teksavvy. Docsis 2 cable modems are good for all speeds upto 18 megabits per second. Docsis 3 modems are strongly recommended for 28 megabit service and above.
The DCM425 is the standard Docsis 2 cable modem for all the small internet providers in Ontario. My units are used, repaired personally by me, and guaranteed for 1 year. Firmware is typically ST52.08.31 as required in Rogers areas, but other firmware is available.
The Motorola SB6120 is a Docsis 3 modem with a strong track record of reliability. These are used modems guaranteed for 1 year. All units are upgraded to the currently required 220.127.116.11 firmware, so they are ready to go for officially supported use.
The SMC SMCD3GN is a Docsis 3 cable modem with built in wireless N router. It is the standard modem issued by Rogers for the last few years and is officially supported by all providers in Rogers territory. My units are used, but guaranteed for 1 year.
