secondedA router is a good idea no matter how many machines you have if for no other reason than it offers an increased measure of security over just being connected straight to the modem.
With Rogers they specifically put a line on the bill for the modem rental and it is $0.00. The only discount you can get with Rogers is the VIP discount - $4.50. It's a nice discount.Through Shaw they don't mention that if you buy the Cable Modem your monthly payment is $5 cheaper!! So I guess you are renting it, they just don't tell ya
