What is a WiFi router?
A WiFi network (a.k.a wireless network) uses a radio frequency signal instead of wires to connect your devices - such as computers, tablets, and smartphones - to the Internet and each other. The WiFi signal can be carried up by any wireless-capable device such as a laptop or tablet within a certain distance in all directions.
A router is the central hub of your home network. It connects directly to your network cable or via a modem. All inbound and outbound traffic pass through the router.
It is used to provide access to the Internet or a private computer network. Depending on the manufacturer and model, it can function in a wired local area network, a wireless-only LAN, or a mixed wired and wireless network.

The WiFi Alliance also announced would like to see these numbers appear in software so you can tell which WiFi network is newer and faster while connecting on your smartphone, tablet, or laptop. So you may be seeing WiFi numbers on your phone, tablet, or laptop.
Older versions of WiFi aren’t widely in use and aren’t officially being branded. But, if they were, here’s what they’d be called:
Earlier WiFi Generations:
- WiFi 1 would have been 802.11b, released in 1999.
- WiFi 2 would have been 802.11a, also released in 1999.
- WiFi 3 would have been 802.11g, released in 2003.

What Kind of WiFi Router Do I Need?
Depending on your internet service provider (ISP), you may need to buy a router, a router, and separate modem, or a router modem. Nearly all ISPs use either DSL or fiber for their service, requiring a modem's signal conversion. Most modern routers have modems built-in, so you only need one device.
Since most of the modem router combo’s performance is not good enough, if you want a better WiFi experience, it’s better to purchase a separate router.
