What a modem does
A modem connects the home to the internet provider’s network. Cable, fibre, and DSL services use different equipment, so a modem that works for one service may not work for another.

Modems and routers: plain-English basics
Urban no longer sells or rents modems. This page has been reframed as a general educational guide about modems, routers, Wi-Fi, and compatibility questions.
What a router does
A router shares the connection with your devices and usually creates the Wi-Fi network. Some devices combine modem and router functions in one box.
Why compatibility matters
Providers often require approved equipment, firmware versions, or provisioning records. Before buying used equipment, check with the current provider.
