To tell if your PC has a wireless card, open Device Manager, expand Network adapters, and look for an adapter with "wireless," "Wi‑Fi," or "WLAN" in its name. If you see one, your PC has built-in Wi‑Fi hardware and can connect to a wireless network, handy for tasks like a wireless printer setup (wireless printer setup) without needing extra cables.
Checking Device Manager
- Open Start and type Device Manager.
- Select Device Manager from the search results.
- Expand Network adapters by clicking the arrow next to it.
If the adapter is listed with a warning icon, open Properties and check the Problem number. If the adapter shows a down-arrow icon, right-click it and choose Enable device to turn it back on. If it shows a warning icon (yellow exclamation mark), open its Properties and check the Problem number for details on the driver issue.
Checking Network Connections
On iPhone, Apple says to open Settings and tap Cellular to view cellular hardware and settings. Apple says Cellular Data can be turned on or off from Settings > Cellular. Apple says cellular settings can be used to turn cellular data on or off for individual apps.
What it means if no wireless adapter appears
If no wireless adapter is listed under Network adapters, Microsoft says Windows is not detecting the wireless hardware. This can mean the adapter is missing, disabled in the BIOS, has a missing or corrupted driver, or the Wi‑Fi hardware itself is physically faulty or disconnected. In any of these cases, you can still connect to Wi‑Fi by using a USB or PCIe Wi‑Fi adapter that you install yourself.
