Dear Friend! hope below steps can help u:
For Huawei ONTs with Wi-Fi functions, such as HG8045, HG8045A, HG8245, HG8245H, HG8245Q,
HG8245T, HG8247 and HG8247H, perform the following steps:
(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.
Cheers,
