NT Broadband Router Login

NT Broadband is the fixed broadband service operated by National Telecom Pcl, a Thai state-owned telecommunications company formed from the merger of TOT Public Company Limited and CAT Telecom. The provider focuses on affordable internet plans targeting rural and semi-urban areas across Thailand, though it also serves customers in Bangkok and other major cities. Most routers supplied by the provider use 192.168.1.1 as the default gateway IP address, with Huawei and ZTE hardware deployed across the network.

How to Login to Your NT Broadband Router

To access the NT Broadband router admin panel, connect to your network through Wi-Fi or a LAN cable. Open a browser and type the IP address 192.168.1.1 in the address bar. The login page will appear after a few seconds.

Enter admin as the username and admin as the password. Some newer models have a unique password on the router label. Check the sticker on the bottom of your device if the default does not work.

The provider maintains a customer service line at 1888 for account and technical support. Full router configuration, including DHCP, port forwarding, and wireless settings, requires the web admin panel at 192.168.1.1.

If the login page does not load, verify you are connected to the NT network and not mobile data. Type http://192.168.1.1 with the prefix in the address bar.

NT Broadband Router Models and Default Settings

The service has deployed several router models. The unit you receive depends on your plan tier and installation date.

Router Model	Default IP	Username	Password	Notes
Huawei HG8145V5	192.168.1.1	admin	admin	Most common model
Huawei HG8245H	192.168.1.1	admin	admin	Older installations
ZTE F670L	192.168.1.1	admin	admin	WiFi 6 capable
ZTE F660	192.168.1.1	admin	admin	Legacy ADSL/VDSL areas
Huawei EG8145V5	192.168.1.1	admin	On label	Newer fibre plans

The Huawei HG8145V5 is the most widely deployed unit. It functions as a combined ONT and router with dual-band Wi-Fi. The ZTE F660 appears in older installations, particularly in areas that were previously on TOT’s ADSL network before the merger.

Changing Your NT Broadband Wi-Fi Password

Subscribers should change the default Wi-Fi password after installation. The default credentials are common across many ISPs in Thailand. Here is the process for the Huawei HG8145V5.

Log in at 192.168.1.1 with your admin credentials. Click on WLAN in the top menu. The 2.4 GHz and 5 GHz networks will appear under SSID Configuration.

Select the SSID to modify. Change the SSID Name to a name you prefer. In the WPA PreSharedKey field, type your new password. Use at least 12 characters with a mix of letters, numbers, and symbols.

Click Apply. All connected devices will disconnect and need to rejoin. Repeat for both frequency bands to keep your settings consistent.

Using Your Own Router with NT Broadband

The provider supports the use of third-party routers. The supplied ONT manages fibre authentication and provides Ethernet output.

Steps to connect your own router:

1. Log in to the ONT at 192.168.1.1 and disable the built-in Wi-Fi to reduce interference.
2. Connect your router’s WAN port to the ONT’s LAN port 1 using an Ethernet cable.
3. Set your router’s WAN connection type to DHCP or PPPoE depending on your plan. Contact 1888 if you are unsure which type your plan uses.
4. If your router also defaults to the 192.168.1.x subnet, change its LAN IP address to a different range (such as 192.168.0.x) to avoid conflicts.
5. Restart both devices and verify that the connection works.

NT Broadband plans inherited from the former TOT network sometimes use PPPoE. Plans on the former CAT Telecom infrastructure may differ. Confirm your connection type before setting up a third-party router.

Subscribers in Thailand who also use True Online report similar ONT compatibility with popular routers like the TP-Link Archer AX73 and Asus RT-AX86U.

Troubleshooting NT Broadband Router Issues

Here are the most common router problems and how to fix them.

1. Login page does not load. Confirm you are on the NT network and not on mobile data. Type http://192.168.1.1 with the prefix. Use a LAN cable instead of Wi-Fi. Reset the router if the page still does not appear.

2. Password rejected. Check the router label for a unique password. Technicians may set a custom password during installation. A factory reset (hold the reset button for 10 to 15 seconds) restores defaults.

3. Connected but no internet. Power cycle the ONT by unplugging it for 30 seconds, then restart the router. If you use PPPoE, verify your credentials are correct. Contact 1888 if the issue continues.

4. Slow Wi-Fi speeds. Test with a wired connection first. The service delivers full speed over Ethernet. If Wi-Fi is the bottleneck, use the 5 GHz band for devices near the router. A third-party router or mesh system improves coverage in larger homes.

5. Red LOS light on the ONT. A red LOS light indicates fibre signal loss. Inspect the fibre cable from the wall outlet to the device for damage or sharp bends. Do not bend fibre cables. Contact 1888 if the cable appears undamaged.
