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 o-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 o and then is lit, the
system restarts successfully.
NO TE
Exercise caution when restoring factory settings. This function may cause the loss of ONT
conguration information and further cause an Internet access failure. If this problem
occurs, contact your service provider for help.
How can I download Huawei ONT rmware or ONT 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
rmware or software.
