Hello, friend!
You need to log in to the web page of the HG8245W5-6T to configure the HG8245W5-6T. The procedure is as follows:
1. Use a network cable to connect the LAN port of the ONT to a PC.
2. Ensure that the Internet Explorer (IE) of the PC does not use the proxy server. The following section considers IE 10.0 as an example to describe how to check whether the IE uses the proxy server. The ONT WEB page does not support browsers of Windows Internet Explorer 8 or earlier versions.
a) Start the IE, and choose ToolsInternet Options from the main menu of the IE window. Then, the Internet Options interface is displayed.
b) In the Internet Options interface, click the Connections tab, and then click LAN settings.
c) In the Proxy server area, ensure that the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections). check box is not selected (that is, without the "√" sign). If the check box is selected, deselect it, and then click OK.
3. Set the IP address and subnet mask of the PC. For details.
4. Log in to the Web configuration interface.
a) Enter http://192.168.100.1 in the address bar of IE (192.168.100.1 is the default IP address of the ONT), and then press Enter to display the login interface

NOTE: The web page login supports SSL3.0, TLS1.0, TLS1.1, and TLS1.2. It is recommended that you use high-security TLS1.1 or TLS1.2 if you log in to the ONT using https. The TCP port 80 is used for listening for HTTPS packets. You need to type "https://192.168.100.1:80" in the address bar of IE and press Enter to log in to the ONT.
b) In the login interface, enter the user name and password.
User name: root
Password: adminHW
After the password authentication is passed, the Web configuration interface is displayed.
Thanks!
