What Is WiFi and Why It Matters

WiFi is a wireless networking technology that allows devices to connect to the internet and communicate with each other without physical cables. A computer with WiFi support contains a wireless network adapter, which communicates with a wireless router or access point using radio signals.

Knowing whether your computer has WiFi matters for several reasons. If you are setting up a new home office, you need to know if you can place your computer anywhere within range of the router or if you must run an Ethernet cable. If you are troubleshooting a connection issue, confirming that wireless hardware exists helps you avoid wasting time on software fixes for a machine that simply lacks the capability. Finally, if you plan to buy a wireless printer, smart home hub, or other network device, your computer must have WiFi to discover and manage those products easily.
