usin hotspot to connect laptop

Hi uthpala227,

To my experience, you've connected the hotspot to your laptop. Your laptop will remember that password and tries to join it with your old password. Try to click "Forget" on your device:

If you use a Mac:

1. Choose Apple menu  > System Preferences, then click Network.
2. Select Wi-Fi in the list on the left.
3. Click the Advanced button.
4. The Wi-Fi pane shows a Preferred Networks list. Select the Wi-Fi network that you want your Mac to forget.
5. Click the remove button (–) beneath the list. If you're asked to confirm, click Remove.
6. Click OK.
7. Click Apply.

If you're using a Windows device:

1. Open the Wi-Fi options bar
2. Right click your hotspot
3. Click "Forget"

After you're done, join the hotspot again and enter the password.
