5 FAQS

How do I log in to the Huawei ONT web page?

NOTE

You are advised to use the latest browser to log in to the web configuration page. Chrome 58/Edge 14/Firefox 54/Safari 10/Opera 55 or later is recommended. If the browser of an earlier version is used, compatibility issues may occur.

• Wireless login

1. Connect your mobile phone, pad, or PC to the Wi-Fi network of the Huawei ONT.
2. Enter the IP address in the address box of a browser and press Enter. On the displayed login page, enter the username and password. (For details about the IP address, login username, and password, see the product nameplate.)

• Wired login

1. Use a network cable to connect a PC to the Huawei ONT.
2. Set the IP address of the PC in the same subnet as the web address of the Huawei ONT. For example, if the web address of the Huawei ONT is 192.168.18.1 (for the web address of the Huawei ONT, see the product nameplate), set the IP address of the PC to 192.168.18.100.

NOTE

The preceding cable connection diagram and login pages are only for reference, and those of the actual product prevail.

How do I change the Wi-Fi password?

1. Log in to the Huawei ONT web page using your mobile phone, pad, or PC. For details, see "How do I log in to the Huawei ONT web page?"
2. Choose the Advanced > WLAN tab and choose 2.4G Basic Network Settings. (If you want to configure 5G Wi-Fi, choose 5G Basic Network Settings.).

What can I do if I forget the Wi-Fi password?

1. Log in to the Huawei ONT web page using your PC by wired login. For details, see "How do I log in to the Huawei ONT web page?"
2. Choose the Advanced > WLAN tab and choose 2.4G Basic Network Settings. (If you want to configure 5G Wi-Fi, choose 5G Basic Network Settings.).

What can I do if I cannot connect to the Wi-Fi network?

Check whether the Wi-Fi network name and password are changed.

• Yes: Connect to the Wi-Fi network using the modified name and password.
• No: Connect to the default Wi-Fi network. For details, see the default Wi-Fi network on the nameplate.

How to improve the Wi-Fi speed of a Huawei ONT?

1. Wi-Fi speed relies on the bandwidth provided by the ISP, so the simplest way is to upgrade to faster broadband.
2. Wi-Fi speed is affected by the Wi-Fi signal strength and quality.
3. Determine the deployment positions of ONT based on house structures, indoor obstacles, and electrical appliance-caused interferences. If possible, put ONT in the middle of a planned coverage area and ensure that no obstacles exist and they are placed at high positions for better coverage. In addition, ensure that the ONT is far away from interference sources such as TVs, refrigerators, cordless phones, and Bluetooth devices.
4. Note that load-bearing walls, floors, and metal coated glass may block Wi-Fi signals, avoid or reduce these obstacles between the ONT and Wi-Fi devices (such as pads, mobile phones, and laptops). For outdoor yards, large balconies, and compound rooms, etc., it is recommended to add repeaters to enhance the Wi-Fi coverage.
5. For common places where users access the Internet, such as a living room, study room, or master room, pre-evaluate whether their signal strength is strong enough. If the signal strength is insufficient(Generally, lower than -72dBm), it is recommended to adjust ONT positions or add new repeaters to enhance the Wi-Fi coverage.
6. Using the correct radio channel. Generally, the Huawei ONT automatically selects the optimal channel. If the network is slow or the quality turns poor from time to time, you can use a Wi-Fi scanner such as Wi-Fi Stumbler or Wi-Fi Analyzer to search for the optimal channel.
7. To prevent unauthorized network access, log in to the web interface of the router and select MAC address filtering based on your requirements.

What can I do if the network speed is slow?

1. Check whether network cables are properly connected. Remove and then insert the network cables. Then, check whether the network speed is normal.
2. Check whether downloading, network video watching, or other operations occupy a large amount of bandwidth. Due to bandwidth restrictions, if some network applications occupy a large amount of network bandwidth, the network speed is slow.
3. Use another PC, mobile phone, or pad to check whether the network speed is normal.

A phone does not ring upon an incoming call but communication is in normal state when the phone is in off-hook state.

The ONT supports a maximum of 60 V AC ringing current voltage. Check whether the ringing current voltage of the phone is higher than 60 V AC. If it is higher than 60 V AC, replace the phone.

How do I restore the Huawei ONT to factory setting?

Press Reset by using a needle-type object for longer than 10s to restore factory defaults and reset the Huawei ONT. If the indicator is off and then is lit, the system restarts successfully.

NOTE

Exercise caution when restoring factory settings. This function may cause the loss of ONT configuration information and further cause an Internet access failure. If this problem occurs, contact your service provider for help.

How can I download Huawei ONT firmware or software?

Huawei ONT is used with an OLT and NMS of a required version. If the versions are not the required ones, the ONT may not work.

If required, contact your internet service provider to obtain the correct ONT firmware or software.
