1. HG8145V5 Default Login and Credential Configurations
Use the following credential configurations to log into your Huawei HG8145V5 ONT. Keep in mind that different accounts provide different configuration permissions. See also our full Huawei default password directory for the complete list across all device families.
| Username | Password | Privilege Level | Available Configuration Options |
|---|---|---|---|
| telecomadmin | admintelecom | Root Administrator | Full access. Create WAN profiles, configure VLAN tags, bridge mode, port forwarding, and voice. |
| root | admin | Standard User | Limited access. View system diagnostics, configure basic Wi-Fi keys, and check optical power levels. |
| admin | admin | Standard User | Limited access. Standard fallback login configuration for older firmware revisions. |
2. How to Access the HG8145V5 Admin Page
If the default IP address does not load, follow this troubleshooting guide to restore access. For universal browser diagnostic steps that apply to all brands, see our router login not working guide.
Check Your Local IP Subnet
If the ONT is connected to a secondary router, your computer might be receiving an IP address from the secondary router's subnet (such as 192.168.1.X or 192.168.3.X). To load 192.168.100.1, disconnect your secondary router, plug your PC directly into the ONT, and reboot your computer to lease a fresh IP from the ONT's DHCP server. If this creates a Double NAT situation, configure Bridge Mode on the ONT.
Query Optical Signal Power
Log in as a standard user (root/admin) and navigate to Status > Optical Information. Verify that the Rx Optical Power is between -8 dBm and -27 dBm. If it is lower than -27 dBm (e.g. -30 dBm), the optical signal is too weak, causing packet loss and interface disconnects. Use our packet loss fix guide to understand signal degradation and troubleshooting steps.
3. Configuring the HG8145V5 in Bridge Mode
Running the HG8145V5 in Bridge Mode allows you to connect a dedicated router behind the ONT, giving you full control over NAT, DHCP, QoS, and Wi-Fi. This eliminates Double NAT and improves gaming performance. Here is the step-by-step process:
- 1Log into the ONT at http://192.168.100.1 using telecomadmin / admintelecom.
- 2Navigate to WAN → WAN Configuration and click the 'New' button.
- 3Set Mode to 'Bridge', enter your ISP's VLAN ID (check your ISP documentation), and select Connection Type as 'IPoE' or 'PPPoE' as required.
- 4Bind the WAN interface to LAN Port 1 in the interface binding section.
- 5Connect your personal router's WAN port to LAN Port 1 on the ONT with an Ethernet cable.
- 6Configure your personal router to dial PPPoE using your ISP username and password.
For more details on optimal router settings after Bridge Mode, explore our router settings optimization guide and the port forwarding setup guide.

Quick Fix Checklist
- 1Connect your computer to LAN Port 1 or LAN Port 2 of the HG8145V5 using an Ethernet cable.
- 2Open your web browser and navigate to the default ONT IP: http://192.168.100.1.
- 3Try entering the high-privilege credentials: telecomadmin / admintelecom.
- 4Use root / admin as a secondary fallback login if admintelecom is rejected.
- 5Do not factory reset the ONT unless you have documented your GPON LOID authorization key.
Common Root Causes
ISP Remote TR-069 Changes
Fiber internet providers push automatic firmware configurations that rewrite the default telecomadmin logins to secure custom credentials.
LOID Authentication Failures
Performing a hardware reset wipes ISP authorization credentials, preventing the ONT from syncing with the GPON fiber line.
Wrong LAN Port Hookups
Connecting your PC to LAN ports configured for IPTV or VoIP prevents your computer from leasing an IP and accessing the login page.
Step-by-Step Diagnostic Resolution Flow
- 1
Establish Wired Ethernet Link to the HG8145V5
Because the HG8145V5 is a GPON Optical Network Terminal (ONT), configuring settings over Wi-Fi can lead to dropped sessions during network commits. Connect an RJ45 Ethernet cable from your computer's network interface card to LAN Port 1 or LAN Port 2 on the side panel of the Huawei ONT. Ensure that your computer's network adapter settings are configured to automatically obtain an IP address via DHCP.
Expert Tip: Avoid using LAN Port 4 if your ISP utilizes it for IPTV bridging, as this port may not lease local IP addresses to standard computer clients. - 2
Navigate to 192.168.100.1 in Your Web Browser
Open a web browser on your connected computer. In the URL address bar, enter the default ONT IP address 'http://192.168.100.1' and press Enter. This will load the official Huawei administration portal. If a security warning appears stating that the connection is unencrypted, click 'Advanced' and then 'Proceed' to bypass the warning and load the panel.
Expert Tip: If the page does not load, verify that your computer has obtained a local IP in the 192.168.100.X range by typing 'ipconfig' in command prompt. If it shows 169.254.x.x, read our gateway diagnostic guides. - 3
Enter the High-Privilege 'telecomadmin' Account Credentials
To obtain full administrative access to configure fiber settings, enter Username 'telecomadmin' and Password 'admintelecom' in the login fields. If your ISP has pushed a custom remote profile, this default might fail. In that case, look at the physical sticker on the bottom of the ONT for custom ISP access keys, or try the standard user credentials: Username 'root' and Password 'admin'.
Expert Tip: Always prefer 'telecomadmin' over 'root' because the root profile blocks critical menus including WAN interface setups, VLAN mappings, and TR-069 ACS configuration. - 4
Perform a Hardware Reset if Custom Credentials Fail
If the administrator logins have been modified and you cannot access the system, you must perform a hardware reset. Locate the recessed 'Reset' button on the side panel. With the ONT powered on, press and hold the button using a paperclip or SIM ejector tool for exactly 10-15 seconds. Release the button. The ONT status lights will power off and cycle. Wait 2 minutes for the system to re-initialize defaults.
Expert Tip: Warning: Resetting your ONT will wipe your GPON LOID (Logical ONT Identifier) or SLID authorization keys. If your ISP requires LOID authentication, you will lose internet access and must contact support to re-provision the ONT.
When To Contact Your ISP
If you log in and the GPON status indicates 'O5 Operation' but the WAN IP is empty, your ISP has disabled the MAC address lease. If the LOS light is blinking red, the fiber optic cable is damaged. In both cases, contact your ISP support team to resolve the issue.
Expert Q&A & Troubleshooting Insights
What is the telecomadmin password for Huawei HG8145V5?
The factory default username is 'telecomadmin' and the default password is 'admintelecom'. This account gives full configuration control over the ONT, allowing you to configure WAN connections, VLANs, and bridge modes.
How do I set up Bridge Mode on the HG8145V5?
Log in as telecomadmin. Navigate to the WAN tab. Create or edit the WAN interface, change the WAN Mode from Route to 'Bridge', select the appropriate VLAN ID (if required by your ISP), and bind the interface to a physical LAN port (e.g. LAN 1) where you will connect your personal router.
What does a blinking LOS red light mean on HG8145V5?
A blinking red LOS (Loss of Signal) light means the ONT is not detecting optical light on the fiber interface. Check that the green fiber connector on the bottom is plugged in securely and there are no sharp bends in the cable. Contact your ISP if line levels drop below -27 dBm.
Why is the PON light flashing green?
A blinking green PON (Passive Optical Network) light indicates that the ONT is attempting to handshakes and authenticate with the ISP's central office OLT. If it blinks indefinitely, the ONT is not provisioned on the provider's network or the LOID key is incorrect.
How do I change the Wi-Fi SSID and password on the HG8145V5?
Log into the admin portal, navigate to the WLAN tab. Select WLAN Configuration. Modify the SSID Name, set Security Mode to WPA2-PSK or WPA2/WPA3-PSK, enter your secure wireless password in the Pre-shared Key field, and click Apply.
Can I connect a personal router to the HG8145V5?
Yes. If you configure the HG8145V5 in Bridge Mode (as telecomadmin), you can connect a personal router to LAN Port 1. Your personal router will then handle NAT, DHCP, Wi-Fi, and firewall independently — known as PPPoE pass-through. This eliminates Double NAT issues and gives you full control over your network.
