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 (Windows) or menu bar (Mac). Turn on Wi‑Fi and turn off airplane mode. Some laptops 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 laptop; if still off, the adapter may have failed.

Check if other devices connect

Goal: Isolate laptop vs router.

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

Forget and reconnect

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

  • On the laptop, 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 laptop connects. You are done.
  • Bad: Still fails—proceed to Update Wi‑Fi driver.

Update Wi‑Fi driver

Goal: Fix outdated or corrupted driver.

  • In Windows: Device Manager → Network adapters → right-click the Wi‑Fi adapter → Update driver. On Mac: check for system updates. Restart after updating.
  • Good: Driver updated and the laptop 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 laptop.

  • Unplug the router for 60 seconds and plug it back in. Restart the laptop. If needed, reset network settings (Windows: Network reset; Mac: remove and re-add Wi‑Fi service).
  • Good: The laptop 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 the laptop manufacturer or a technician if:

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

Verification

  • The laptop 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 laptop; reset network settings.
  5. Call support Adapter missing, yellow warning persists, or all steps failed.

Is Wi‑Fi on and airplane mode off?

Hardware switch or Fn key may have turned Wi‑Fi off.

Check the Wi‑Fi icon. Turn on Wi‑Fi and turn off airplane mode. Look for a physical switch or Fn+F2. Good: Wi‑Fi on—check if other devices connect. Bad: Wi‑Fi off—turn it on and retry.

Yes No

Turn on Wi‑Fi

Enable Wi‑Fi in settings. Turn off airplane mode. Check for a hardware switch or Fn key. Restart the laptop if Wi‑Fi still does not appear.

Done

Can other devices connect to the same network?

If no device connects, the issue is the router.

Try a phone or another laptop. Good: other devices connect—focus on this laptop (forget network, update driver). Bad: no device connects—check router; see Fix a Wi‑Fi that will not show network.

Frequently asked questions

Why would a laptop not connect to Wi‑Fi?
Wi‑Fi adapter disabled (hardware switch or airplane mode), outdated or corrupted driver, wrong password, or router rejecting the device. Check Wi‑Fi is on and update the driver first.
Can I fix a laptop that will not connect to Wi‑Fi myself?
Yes. Turn on Wi‑Fi, forget and reconnect to the network, update the Wi‑Fi driver in Device Manager, and power-cycle the router. If the adapter is missing from Device Manager, a technician may be needed.
When should I call support for Wi‑Fi connection?
If the Wi‑Fi adapter does not appear in Device Manager, other devices connect but the laptop never does, or you have tried driver update and network reset with no change.
