Setting up your 4G Huawei B628 modem correctly ensures reliable home broadband and stable local network performance. This guide walks you through initial placement, physical connections, and software configuration so you can get online quickly.
Use the overview below to compare default settings and main features across firmware versions, helping you choose the right configuration path for your connectivity needs.
| Model | Network Mode | Typical Downlink Speed | Recommended Use |
|---|---|---|---|
| Huawei B628 | LTE-FDD + TD-LTE (4G) | Up to 1.6 Gbps aggregate | Home broadband, small office |
| Firmware Type | Standard (HiLink) / Full Versatile (VR) | Varies by region update | Plug-and-play vs advanced control |
| Ethernet Ports | 1x GE WAN / 1x GE LAN (switch) | Gigabit performance | Wired desktops, AP connections |
| Wi‑Fi | Dual‑band 2.4 GHz + 5 GHz | AC1200 class | Multi‑device home coverage |
Preparing Your Installation Environment
Place the modem near a window for better 4G signal and use a short coaxial or LTE cable to reduce losses. Keep it upright, avoid metal enclosures, and ensure ventilation to prevent overheating during sustained use.
Check the SIM card is active, properly inserted, and has sufficient data allowance. Verify that your carrier supports the B628 bands in your region, and note the APN details you will need during initial setup.
Physical Connection and First Boot
Connecting Power and Ethernet
Attach the power adapter to the modem, connect the cable to a stable power source, and wait for the status LEDs to initialize. Connect your computer to the LAN port using an Ethernet cable for the initial configuration step.
LED Status Indicators
Observe the power, signal, and network LEDs; a solid signal bar and LTE network light usually indicate the modem has registered to the 4G network and is ready for data transfer.
Accessing the Web Management Interface
Open a browser and enter the default LAN IP, typically 192.168.1.1, then log in using the credentials printed on the modem label. Once inside, update the firmware if prompted and configure the connection mode to your carrier requirements.
Set the network mode to LTE/4G, choose the correct band profile for your region, and enter the APN, username, and password supplied by your mobile operator to establish a data connection.
Wi‑Fi Setup and Secure Configuration
Creating SSIDs and Security Settings
Create separate SSIDs for 2.4 GHz and 5 GHz networks, enable WPA2‑AES or WPA3 where available, and set a strong passphrase. Disable WPS if you do not need it to reduce the attack surface.
Parental Controls and Traffic Management
Use built‑in parental controls to schedule internet access for devices and prioritize critical traffic via QoS rules. This helps maintain video calls and gaming performance during heavy household usage.
Troubleshooting Connectivity Issues
If the modem does not connect, reseat the SIM, reboot the device, and verify that the chosen network mode matches your carrier deployment. Check for firmware updates and ensure the firmware version aligns with your region and hardware revision.
For persistent issues, review system logs in the web interface, test with another known‑good SIM, and verify that the modem location has acceptable signal strength and minimal interference from other electronics.
Final Setup Recommendations
- Verify correct carrier bands and APN settings before powering on the modem
- Keep firmware up to date to improve stability and security
- Use wired Ethernet for stationary devices to maximize speed and reduce wireless contention
- Enable QoS and prioritize critical applications for a smooth user experience
- Place the modem in an open location with strong 4G signal for reliable performance
FAQ
Reader questions
Why does my B628 show no service after inserting the SIM?
Check that the SIM is correctly inserted, properly seated, and activated on the account. Confirm that your carrier supports the B628 and that the device is within coverage area, then reboot the modem and verify the LED status.
How do I update the firmware safely?
Download the official firmware from the Huawei support site for your region, then use the web interface’s firmware upgrade option. Avoid power interruptions during the update and verify the device boots and connects to the network afterward.
Can I use the B628 as a standalone router without a separate modem?
Yes, the B628 functions as an integrated 4G router with Wi‑Fi and LAN ports. Disable any additional upstream modem or set the B628 to bridge mode only if your ISP or upstream equipment requires it.
What should I do if the 5 GHz Wi‑Fi is very slow?
Ensure client devices support 5 GHz and are close to the modem, select a clean channel via the router settings, and check for interference from other devices. If needed, prioritize the 5 GHz band for high‑speed devices in the QoS settings.
