Hello, friend!
1. In most cases, the default user name for logging in to the web page is root, the password is admin and the IP address is 192.168.100.1. However, for security reasons, the default password or IP address may have been changed before delivery. The nameplate prevails. Enter the IP address in the address bar of your browser.
2. Enter the default login account and password on the nameplate on the rear of the ONT and click Login.
3. In the navigation tree on the left, choose WLAN > WLAN Basic Configuration. In the pane on the right, select the Enable WLAN option box. In the dialog box that is displayed, deselect Broadcast SSID.

4. Click Apply.
Thanks!
