“Wi-Fi Authentication Error”
What This Means (In Plain English)
Your phone is trying to connect to a Wi-Fi network but the password you entered is not being accepted.
Common Causes
- •Incorrect Wi-Fi password (check capital letters and special characters)
- •The Wi-Fi password was recently changed
- •A glitch in the saved network settings
- •The router is set to a security type your phone does not support
How to Fix It — Step by Step
- 1
Make sure you are typing the Wi-Fi password exactly right — it is case-sensitive (capital and lowercase letters matter).
- 2
Go to Settings > Wi-Fi, long-press on the network name, and tap "Forget Network".
- 3
Tap the network name again and enter the password carefully.
- 4
If you are not sure of the password, check the sticker on the bottom or back of your router.
- 5
Restart your phone and your Wi-Fi router (unplug the router, wait 30 seconds, plug it back in).
- 6
If using a public Wi-Fi network (like at a cafe), ask staff for the correct password.
How to Prevent This in the Future
Write down your Wi-Fi password and keep it somewhere safe. When entering it, use the "show password" option to make sure you type it correctly.
