Modem vs. Router
What is Modem vs. Router?
The modem brings the internet connection into your building from your service provider — it translates the signal from your cable, fiber, or DSL line. The router shares that connection around your business, creating a local network and giving each device its own internal address.
Why Modem vs. Router Matters
Combo units from ISPs do both — usually poorly. Separating them often improves coverage, performance, and troubleshooting. If your internet drops, knowing which device is at fault saves time and frustration.

An access point is a device that adds Wi-Fi coverage to an existing wired network. It connects to your network via Ethernet cable and broadcasts a wireless signal, extending your network's reach without replacing your router.
