Hi Jeff1956,
You can use the link I provided above to see instructions on how to change your wi-fi password. On that page you will be able to download the user manual for your HT2000W with instructions on how to change the password. In the interest of those who may want to save some data, I'll copy and paste a shortened text-version below:
1. Open a web browser such as Chrome, Firefox, or Internet Explorer.
2. Type www.systemcontrolcenter.com in the address bar and hit Enter
3. Click the Wi-Fi Settings link on the left side menu
4. You will see a login page. The default password is "admin" without quotations
5. Click Login
6. Once you have logged in, you will see the Wi-Fi Settings home screen
7. On the left panel, click Administration.
8. New options will appear in the left panel. Click Password Settings.
9. Type in your old password, followed by your new password, typed twice for verification.
10. Click Save Settings.
11. Once finished applying changes, you will be logged out, and your new password must be used to log in.
Thank you,
Amanda
