MobiFone Router Login

MobiFone Corporation is a Vietnamese state-owned mobile telecommunications operator. The provider offers 4G and 5G home broadband through CPE (Customer Premises Equipment) devices. MobiFone Home targets areas where fibre is not yet available or where wireless broadband offers a faster installation option. The service deploys Huawei and ZTE CPE hardware to subscribers. Most devices use 192.168.8.1 as the default gateway IP address, and the MobiFone Home app provides basic connection management.

How to Login to Your MobiFone Home Router

To access the MobiFone Home router admin panel, connect to the CPE device through Wi-Fi or a LAN cable. Open a browser and type the IP address 192.168.8.1 in the address bar. The login page will load within a few seconds.

Enter admin as the username and admin as the password. Some CPE units have a unique password on the device label. Check the sticker on the bottom of the unit if the default does not work.

The MobiFone Home app provides connection monitoring and data usage tracking. Full device configuration including wireless settings and port forwarding requires the web admin panel at 192.168.8.1.

The service uses a SIM card inside the CPE for cellular connectivity. No fibre or telephone line runs to the device. Performance depends on the 4G or 5G signal strength at your location.

MobiFone Home Router Models and Default Settings

The provider has deployed several CPE models. The unit depends on your plan and the network coverage in your area.

Router Model	Default IP	Username	Password	Notes
Huawei B311-221	192.168.8.1	admin	admin	4G LTE, common model
Huawei B525s-65a	192.168.8.1	admin	admin	4G LTE Cat 6
Huawei B818-263	192.168.8.1	admin	admin	4G LTE-A Pro
ZTE MC801A	192.168.8.1	admin	admin	5G capable
Huawei 5G CPE Pro	192.168.8.1	admin	On label	5G plans

The Huawei B311-221 is the most common unit for standard 4G plans. The Huawei B818 and 5G CPE Pro appear on premium plans in areas with 5G coverage. All Huawei B Series devices share the 192.168.8.1 default gateway. Viettel uses similar CPE models for its wireless broadband offerings.

Changing Your MobiFone Home Wi-Fi Password

Subscribers should change the default Wi-Fi password to secure their network. Here is the process for Huawei B Series CPE devices, which are the most common.

Log in at 192.168.8.1 with your admin credentials. Click on Wi-Fi or WLAN in the menu. The current SSID name and security settings will appear.

Change the Wi-Fi Name (SSID) to something you recognize. In the Wi-Fi Key or Password field, type your new password. Use at least 12 characters.

Click Save or Apply. All connected devices will need to rejoin with the new credentials. On 5G CPE models with dual-band Wi-Fi, repeat for both the 2.4 GHz and 5 GHz bands.

Using Your Own Router with MobiFone Home

The service supports connecting a third-party router to the CPE for improved Wi-Fi performance and coverage.

Steps to connect your own router:

1. Log in to the CPE at 192.168.8.1 and disable the built-in Wi-Fi under WLAN settings.
2. Connect your router’s WAN port to the CPE’s LAN port using an Ethernet cable.
3. Set your router’s WAN connection type to DHCP.
4. Change your router’s LAN subnet to a different range (such as 192.168.0.x) if it also defaults to 192.168.8.x to avoid IP address conflicts.
5. Restart both devices.

This creates a double NAT setup, which works well for browsing, streaming, and most online activities. Gaming or hosting servers may require port forwarding on both devices.

The CPE handles the SIM-based cellular connection. Your personal router simply extends the network with better Wi-Fi range and features. A mesh system helps cover larger Vietnamese homes where the CPE alone cannot reach every room.

Troubleshooting MobiFone Home Router Issues

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

1. Login page does not load. Confirm you are connected to the CPE’s Wi-Fi or LAN port, not your phone’s mobile data. Type http://192.168.8.1 with the prefix. Use a LAN cable if Wi-Fi is unstable. Reset the device using the pinhole button if the page does not appear.

2. Password rejected. Check the device label for a unique password. A factory reset (hold the reset pinhole for 10 seconds) restores defaults. You may need to reconfigure APN settings after reset.

3. No internet connection. Verify the SIM card is properly seated. Check signal strength on the admin panel dashboard. Move the CPE near a window for better reception. If the SIM is active but shows no connection, verify APN settings or contact support.

4. Slow speeds. Cellular broadband performance depends on signal quality and tower congestion. Reposition the CPE near a window or on a higher floor. Check the admin panel for signal strength and connected band information. Evening peak hours typically produce slower speeds.

5. SIM not detected. Power off the CPE completely, remove the SIM card, re-insert it firmly, and power on. If the SIM is still not detected, test it in a phone to confirm it is active. Contact the provider for a replacement SIM if the card is faulty.
