The MAC address lists of PCs in the network are saved on the ONT. Configuring MAC filter rules

enables the PCs that conform to the rules to access the Internet service or disables the PCs that do

not conform to the rules to access the Internet service. A PC may have more than one IP addresses

but a unique MAC address.

Therefore, configuring MAC filter rules effectively controls the Internet service access rights of PCs

in a LAN. Parameters related to the MAC address filter:

far away from the signal source or an obstacle exists, and you are advised to get closer to the

ONT.

(2). Get far away from Wi-Fi signal interference sources such as microwave ovens and cordless

phones.

(3). Try Wi-Fi connection on another terminal. If this problem does not occur, there may be a

problem with the driver or hardware of your original terminal. Then you are advised to update the

driver of the Wi-Fi network adapter and check whether the hardware is damaged.

(4). Change the Wi-Fi name (SSID). Duplicate SSIDs may exist within your terminal reach.

(5). Some viruses may exist and cause the disconnection. You are advised to test viruses by

connecting only one computer and run antivirus software.

22. What Do I Do If Huawei ONT's Wi-Fi Is Slow?

Answer





(1). Power off and restart the ONT. Then try to connect to Wi-Fi again.

(2). Visit your service provider's official website using a network cable for a speed test. If the


network speed is still low, there is a problem with the network and you are advised to contact the

service provider.

(3). Check the Wi-Fi signal strength on your terminal. If the signal strength is weak, you may be

far away from the signal source or an obstacle exists, and you are advised to get closer to the

ONT.

(4). If multiple terminals are connected to the Wi-Fi network, bandwidths are shared and the

speed is low. Check whether you are running bandwidth- hungry services such as download and

game services. If yes, disable these services and then access the Internet.

(5). Get far away from Wi-Fi signal interference sources such as microwave ovens and cordless

phones.

(6). Change the Wi-Fi password (with reference to section 5 What do I do if I forget the Wi-Fi

password of Huawei ONT(HG8240, HG8240T, HG8240W, HG8245, HG8247, HG8247H)) to prevent

the network speed from being slowed down by rogue devices.

23. How Do I Prevent Rogue Devices from

Connecting to My Huawei ONT's Wi-Fi?

Answer





(1). Exercise caution when using software to access Wi-Fi without permission. Such software

uploads a user's Wi-Fi network information without notification. Another user can find this Wi-Fi

network name, obtain the Wi-Fi network key from the software server through a 3G or 4G network,

and access this Wi-Fi network without permission.

(2). Check whether encryption has been performed for the Wi-Fi network. Specifically, log in to

the ONT web page. On the main menu, choose WLAN > 2.4G/5G Basic Network Settings. In WPA

PreSharedKey, do not select Hide.


(3). Check whether the Wi-Fi password is too simple to be cracked. You are advised to set

Authentication Mode to WPA-PSK/WPA2-PSK. Configure and record a password with high security

level, for example, a password containing digits, uppercase letters, lowercase letters, and special

characters. This prevents password cracking.

The following figure shows the details.

Note:

For some ONTs, you can configure a Wi-Fi password after choosing Advanced Configuration >

WLAN > 2.4G/5G Basic Network Settings. on the ONT web page.

(4). By configuring MAC address filtering, you can allow only permitted devices (whitelist) to

access the network, and prevent rogue devices (blacklist) from accessing the network.

49. Can an STA Automatically Switch to an

Access Point with Stronger Signal Strength in

a Smart Wi-Fi Coverage Network?

Answer

● For an STA that has the capability of roaming aggressiveness, it automatically compares the

signal strength among detected access points and switches to an access point with stronger

signal strength.

● For an STA that does not have the capability of roaming aggressiveness, if the ONT finds that

the signal strength of the Wi-Fi device is poor, the ONT disconnects the Wi-Fi device from its current

access point and the Wi-Fi device has to look for an access point with stronger signal strength.

Note:

The action of Wi-Fi roaming and switching is mainly dependent to the user's Wi-Fi terminal. Some

Wi-Fi terminals will continuously attempt to connect to the access point from which they had been

disconnected rather than looking for an access point with stronger signal strength. For these Wi-Fi

terminals, contact the vendor to resolve the roaming and switching issues.

50. Will User Services Be Affected During Wi-

Fi Access Point Switching in a Smart Wi-Fi

Coverage Network?

Answer

● For buffered services (such as video play), no obvious service interruption is sensitive to users

during the switching.

● For services that are not buffered (such as web browsing), services will be interrupted


transiently (varying based on the user devices and Wi-Fi environments) during switching and will

be restored to normal after the switching is completed.

The following table lists the reference data of service interruption duration in various switching

scenarios.

51. How to Resolve Incompatibility Between

GPON and XG-PON ONTs When They Share

the Same ODN?

Answer


Compatibility between GPON and XG-PON ONTs:

This table describes the Tx and Rx wavelengths of GPON an XG-PON ONTs.

Type Downstream Direction Upstream Direction

GPON Center wavelength: Center wavelength: 1310

1490 nm nm

Wavelength range: Wavelength range:

1480-1500 nm 1290-1330 nm

XG-PON Center wavelength: Center wavelength: 1270

1577 nm nm

Wavelength range: Wavelength range:

1575-1580 nm 1260-1280 nm

From wavelengths of XG-PON (asymmetric system with upstream rate 2.5 Gbit/s and downstream

rate 10 Gbit/s) and GPON ONTs, if they share the same ODN, GPON ONTs (above table lists

compatibility) in the earlier stage require wavelength block filter (WBF) for downstream isolation

because they are in poor performance in downstream optical signal isolation from XG-PON

ONTs.

Otherwise, packet loss or even disconnection may occur caused by signal interference. Therefore,

the WBF needs to be added on the ONT or optical splitter.

Solution

The WBF is added on the optical splitter for GPON ONTs that are incompatible with XG-PON ONTs

sharing the same ODN. Specifically,

● Male and female connectors.

● Can be externally connected to the SC/UPC (Shown in the following figure) or AC/APC

connector.

- SC/UPC connector

- ONTs of different types are connected to the same optical splitter


- Only early-stage GPON ONTs are connected to the same optical splitter

Note:

● The time in Compatibility is calculated from the ONT replacement. Detailed markets and BOM

codes needed to be queried.

● For details, collect the ONT SN and provide it to the Huawei technical support engineer for

querying.

53. What Is a Rogue ONT and How to Prevent

Such an ONT?

Answer

If an ONT transmits optical signals to upstream at a timestamp that is not assigned to it, it is called

a continuous-mode ONT. Such an ONT is also call the rogue ONT, which transmits optical signals at

any time. When a rogue ONT exists,

● If the rogue ONT is online, one or all of the other ONTs connected to the same PON port on

the OLT go offline or go online and offline frequently.

● If the rogue ONT is not configured, the other ONTs that are not configured will fail to be

automatically discovered.

Enable rogue ONT detection on the OLT. A rogue ONT will be isolated after being detected.

54. What is Loop Detection?

Answer

If a network cable is connected to two LAN ports of an optical modem, a loop occurs on the port.

A port loop may cause a network storm and service faults. The ONT supports loop detection. If a

loop is detected on a LAN port, the LAN port is isolated to break the loop.


55. What Is the Number of Wi-Fi Accesses?

Answer

It is recommended that no more than 10 devices (including wired and Wi-Fi devices) be connected

to an ONT. If too many devices are connected, the user experience deteriorates.

56. What Are the Restrictions on The

Application of Multiple Management

Channels (including the WebUI) of the ONT?

Answer

If services are provisioned on the NMS (U2000/TR069) and WebUI for an ONT at the same time,

the configurations may conflict and cause service exceptions. It is recommended that you select

an NMS (TR069 or U2000) for service provisioning and subsequent O&M.
