Is fiber internet better than Wi-Fi®?
While fiber and Wi-Fi are both popular technologies for residential internet users, it doesn’t make sense to compare them in this way. Each technology serves a different purpose.
Wi-Fi helps connect nearby devices together into what’s called a local area network (LAN). For example, Wi-Fi can connect your laptops, phones, and other devices to your Wi-Fi gateway or modem. A fiber optic network, on the other hand, is a way of connecting that entire local area network with the wider internet.
Can fiber internet have Wi-Fi?
It’s perfectly normal to use both Wi-Fi and fiber internet together. In that situation, when you send an email, your message will travel over your Wi-Fi network to your Wi-Fi gateway. From there, it will travel over your internet service provider’s fiber optic network and eventually connect with the wider internet.
It is also possible to use fiber internet without Wi-Fi. For example, you could connect directly to your modem with an ethernet cable.
