Fix: WiFi says wrong password

Wrong password errors can happen even with the correct password if the saved network profile is corrupted, the router security mode changed, or the device does not support the router's WiFi settings.

Quick answer

Forget the WiFi network, restart the device, then reconnect carefully. If older devices fail, check whether the router is using WPA3-only security.

Important warning

Some older devices cannot connect to WPA3-only networks. Use WPA2/WPA3 mixed mode if your router supports it.

Try this

  1. 1 Forget the WiFi network on your device.
  2. 2 Restart the device.
  3. 3 Re-enter the password carefully.
  4. 4 Check the password printed on the router label or in the router app.
  5. 5 Try connecting another device with the same password.
  6. 6 If you recently changed router settings, check WPA, WPA2, or WPA3 compatibility.
  7. 7 Restart the router if multiple devices suddenly say the password is wrong.

Common causes

Saved WiFi profile is corrupted.

Password was changed in the router app.

Device is trying to join the wrong network name.

Router security mode changed to WPA3-only.

Keyboard autocorrect, spaces, or capitalization caused a mistyped password.

What to check next

  • Check whether another device can connect with the same password.
  • Check whether there are two similar WiFi network names.
  • Check whether the password contains uppercase letters or symbols.
  • Check whether the router uses WPA3-only mode.
  • Check whether the device is old and only supports older WiFi security.

FAQ

Why does WiFi say wrong password when the password is correct?

The saved network profile may be corrupted, the router security mode may have changed, or the device may be trying to connect to a different network with a similar name.

Should I forget the WiFi network?

Yes. Forgetting the network and reconnecting clears the saved profile and often fixes false wrong-password errors.

Can WPA3 cause wrong password errors?

Yes. Some older devices cannot connect to WPA3-only networks and may show a misleading password error.

Related fixes

Fix: One device cannot connect to WiFi

When only one device cannot connect, the usual causes are a saved bad password, incompatible security mode, blocked device, parental controls, or broken network settings.

Fix: WiFi connected but no internet

This usually means your device is connected to the router, but the router cannot reach the internet, DNS is failing, or only this device has a bad network setting.

Fix: WiFi keeps dropping

WiFi usually drops because of weak signal, interference, router overload, overheating, outdated device software, or a buggy WiFi adapter driver.

Fix: WiFi network not showing up

A missing WiFi network usually means the router is off, hidden, too far away, using a band your device cannot see, or the device's WiFi is disabled or stuck.

Fix: WiFi not working on one device only

If every other device works, the router is probably fine. Focus on the one device's saved network, VPN, DNS, software update, or WiFi adapter.

Fix: WiFi is slow on one device only

Slow WiFi on one device is usually caused by weak signal, background downloads, VPN, old drivers, low-power mode, or that device choosing a crowded WiFi band.
