A sort of related question

When our house was built we wired every room for cable/internet. As a result, when we can, we are hardwired. We've had to buy a combined wireless router for the basement, as well as a signal booster we keep on our first floor. Where we need more than 1 internet connection, such as at the TV, we purchased a hub.

We're not having any speed issues at all.

BUT, the only item we have never replaced is the actual cable modem, which is now about 17 years old.

Should we, as a preventative, just ask the cable company to give us a newer model cable modem?
