I still prefer to own my equipment. With my own router, I can do with it as I please such as installing a custom firmware and having the ability to fine tune the settings.In most cases equipment rental fees are a huge ripoff, but honestly with some of these 6e routers costing $400-$600 it's maybe not quite as bad of a deal. (3.5yrs to breakeven for $600).
The routers that service providers offer tend to be very basic and locked down.
How long do people keep their routers? I've owned my AC router ($250) for 5 years already and don't plan to replace it for at least another year since the manufacturer is still supporting it with firmware updates and the Asuswrt-Merlin project is still on-going. If I bought a 6E router, I'd keep it for just as long.
$14 x 60 months = $840
