Can you get WiFi with just a modem?
No, you cannot get WiFi with just a modem. A modem is responsible for connecting your home to the internet through your Internet Service Provider (ISP), but it does not provide wireless connectivity on its own. To create a WiFi network, you also need a wireless router. The modem handles the incoming signal from your ISP, while the router creates the wireless network that allows devices to connect without physical cables.
If you have a modem-only setup, your internet connection will be accessible only via wired connections through Ethernet cables. This means you would need to connect each device directly to the modem to access the internet, which can be impractical for multiple devices. For a wireless connection, adding a router to your network is essential.
What is the difference between a modem and a router?
A modem and a router serve two distinct but complementary purposes in a home network. The modem connects directly to your Internet Service Provider’s network and translates the data signals, allowing you to access the internet. It is essentially a bridge between your home network and the wider internet. On the other hand, a router takes the internet signal from the modem and distributes it to multiple devices, either through Ethernet cables or via WiFi.
