There are several possible reasons why your laptop is not accepting your Wi-Fi password.
1. Check to make sure that you are entering the correct password. Wi-Fi passwords are case sensitive, so be sure that you are entering the password exactly as it is written.
2. If you are still having trouble, try resetting your router. This will reset your Wi-Fi password as well.
3. Another possibility is that your laptop's Wi-Fi is turned off. Check your laptop's settings to make sure that the Wi-Fi is turned on.
4. If you are still having trouble connecting to your Wi-Fi, you may need to contact your ISP for further assistance.
