Steps

Goal: Check Wi‑Fi is on, rule out adapter and driver issues, forget and reconnect, and isolate hardware vs software.

  • Confirm Wi‑Fi is on and airplane mode is off. Check for a hardware switch or Fn key.
  • Good: Wi‑Fi on. Proceed to Check if other devices connect.
  • Bad: Wi‑Fi off—turn it on and retry.

Check Wi‑Fi is on

Goal: Rule out Wi‑Fi being disabled.

  • Check the Wi‑Fi icon in the system tray. Turn on Wi‑Fi and turn off airplane mode. Some PCs have a physical switch or Fn+F2 (or similar).
  • Good: Wi‑Fi is on and networks appear in the list.
  • Bad: Wi‑Fi will not turn on—restart the PC; if still off, the adapter may have failed.

Check if other devices connect

Goal: Isolate PC vs router.

  • Use a phone or another laptop to connect to the same Wi‑Fi. If other devices connect, the issue is with this PC. If no device connects, the issue is the router.
  • Good: Other devices connect—focus on this PC. Proceed to Forget and reconnect.
  • Bad: No device connects—power-cycle the router; see fix-wifi-will-not-show-network.

Forget and reconnect

Goal: Clear cached settings and re-enter the password.

  • On the PC, go to Wi‑Fi settings and forget (remove) the network. Reconnect and enter the password. Check caps lock is off and the password matches the router.
  • Good: The PC connects. You are done.
  • Bad: Still fails—proceed to Update Wi‑Fi driver.

Update Wi‑Fi driver

Goal: Fix outdated or corrupted driver.

  • Device Manager, Network adapters, right-click the Wi‑Fi adapter, Update driver. Restart after updating.
  • Good: Driver updated and the PC connects. You are done.
  • Bad: Adapter missing or yellow warning—reinstall the driver or call support.

Power-cycle and reset

Goal: Clear stuck state on router and PC.

  • Unplug the router for 60 seconds and plug it back in. Restart the PC. If needed, reset network settings (Settings, Network & Internet, Network reset).
  • Good: The PC connects after power-cycle or reset.
  • Bad: Still fails—check if the Wi‑Fi adapter appears in Device Manager. If missing, call support.

When to get help

Call a technician if:

  • The Wi‑Fi adapter does not appear in Device Manager.
  • Other devices connect but this PC never does after driver update and network reset.
  • The adapter shows a yellow warning that persists after reinstall.

Verification

  • The PC connects to Wi‑Fi and stays connected.
  • Web pages load (test with fast.com or similar).
  • No “Can not connect” or authentication errors.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Wi‑Fi on Confirm Wi‑Fi is on; airplane mode off; check hardware switch.
  2. Forget and reconnect Remove network; reconnect with correct password.
  3. Driver Update or reinstall Wi‑Fi driver in Device Manager.
  4. Power-cycle and reset Power-cycle router and PC; reset network settings.
  5. Call support Adapter missing, yellow warning persists, or all steps failed.
