192.168.0.100 Default Login Credentials

Most devices using 192.168.0.100 come with these default username/password combinations:

If none work, check the sticker on the bottom of your ONT or contact your ISP for the admin credentials. Some ISPs lock the superadmin account. You can also try a factory reset to restore defaults.

How To Login to 192.168.0.100

1. Connect to your ONT — use an Ethernet cable connected directly to one of the ONT's LAN ports. If your ONT has WiFi enabled, you can also connect wirelessly.
2. Open a web browser — type http://192.168.0.100 in the address bar (not the search bar) and press Enter.
3. Enter your credentials — use the defaults from the table above. If the ONT was provisioned by your ISP, they may have set custom credentials.
4. Access the admin panel — after login, you'll see the ONT management interface for configuring network and fiber settings.

Huawei Fiber ONT Devices and 192.168.0.100

Huawei is the world's largest manufacturer of fiber optic ONT (Optical Network Terminal) equipment, and the HG8245 series is their most widely deployed consumer fiber device. ISPs across Asia, Africa, the Middle East, and Latin America provision millions of Huawei HG8245H, HG8245Q, and HG8546M units to their fiber-to-the-home (FTTH) customers. These devices typically use 192.168.0.100 or 192.168.100.1 as their default management IP address.

A key challenge with Huawei ONTs is the dual-account system. Most Huawei ONTs have two login accounts: a regular admin account with limited access, and a telecomadmin (or similar superadmin) account with full configuration rights. ISPs often change the telecomadmin password during provisioning to prevent customers from modifying critical fiber parameters like VLAN settings, SIP credentials for VoIP, or GPON serial numbers. If you need superadmin access, you may need to contact your ISP or search for your specific model's default telecomadmin password.

From the admin interface at 192.168.0.100, you can manage basic WiFi settings, view connected devices, check optical signal levels (important for diagnosing fiber issues), configure LAN ports, and set up port forwarding. The optical power reading (measured in dBm) is particularly useful — values between -8 dBm and -25 dBm are normal for most GPON connections. If the receive power drops below -27 dBm, you likely have a fiber quality issue that requires your ISP's attention.

What Is 192.168.0.100?

192.168.0.100 is a private IP address defined by RFC 1918. It falls within the Class C private range of 192.168.0.0 to 192.168.255.255. Within the 192.168.0.0/24 subnet, it is the 100th usable host address. Huawei and other ONT manufacturers chose this address to sit far from the common .1 gateway, reducing the risk of IP conflicts with routers connected behind the ONT.

In a typical FTTH (Fiber To The Home) setup, the ONT at 192.168.0.100 acts as the bridge between your ISP's fiber optic network and your home Ethernet/WiFi network. The ONT converts optical signals from the fiber cable into electrical signals that your router and devices can use. Some ONTs function purely as media converters (bridge mode), while others like the Huawei HG8245 include a built-in router with WiFi, DHCP, firewall, and NAT functionality.

Because 192.168.0.100 is a private address, it cannot be accessed from outside your local network. You must be physically connected to the ONT — either by Ethernet or WiFi — to access the management interface. If a separate router sits between your computer and the ONT, you may need to connect your computer directly to the ONT via Ethernet cable, temporarily bypassing your router, to reach 192.168.0.100.

Pro Tip: After your first login, immediately change the default admin password to prevent unauthorized access. Also consider updating the firmware for security patches.

Frequently Asked Questions

What is 192.168.0.100 used for?

192.168.0.100 is the default management IP for Huawei HG8245 fiber ONT devices and similar fiber optic modems. It provides access to the device admin panel for managing WiFi, viewing fiber signal levels, and configuring network settings.

Why can't I access 192.168.0.100?

You may be connected to a router behind the ONT rather than directly to the ONT itself. Connect via Ethernet directly to the ONT's LAN port. Also try 192.168.100.1 as an alternative. See our find your router IP guide.

What is the default username and password for 192.168.0.100?

Common defaults include admin/admin, telecomadmin/admintelecom, and root/admin. Your ISP may have changed these during provisioning. Check the label on your ONT or contact your ISP for credentials.

How do I reset my ONT password?

Hold the reset button on the ONT for 10-15 seconds to factory reset. Warning: this may erase ISP provisioning data, and you may need to contact your ISP to re-activate your fiber service.

Is 192.168.0.100 the same as 192.168.100.1?

No. These are different IP addresses on different subnets. 192.168.0.100 is on the 192.168.0.x subnet, while 192.168.100.1 is on the 192.168.100.x subnet. Different Huawei ONT models and ISP configurations use one or the other.

What is the telecomadmin account on Huawei ONTs?

The telecomadmin account is a superadmin account with full configuration access, including VLAN, VoIP, and GPON settings. ISPs often change this password to prevent customer modification of critical fiber parameters. The default is usually telecomadmin/admintelecom.

How do I change my WiFi password at 192.168.0.100?

Login to the admin panel, navigate to WLAN or WiFi settings, change the WPA Pre-Shared Key field, and click Apply. See our WiFi name change guide for step-by-step instructions.
