Broadband Service

Simple Troubleshooting Guidelines

There are many possible reasons why you might not be able to access the Internet. Please refer to the following guidelines for troubleshooting.

  1. Please check whether the network cables are loose. Reconnect the cables on all devices after closing all the connected devices, and then turn on the devices to test;
  2. If you are using any network sharing device (router), please try unplugging the device and connecting your computer directly to our modem or wall-mounted network cable, and then carry out the testing;
  3. If the problem persists, or if you are not using any web sharing device, please switch to a different browser (such as Edge/Firefox/Chrome/IE) and a different device (such as another computer/mobile phone/tablet) for testing.

A disconnection problem during surfing may be related to loose network cables, network conditions and your computer’s settings. Please refer to the following guidelines to handle the problem.

  1. Please check the network cables for any possibility of poor contact. Reconnect the cables on all devices after closing all the connected devices, making sure that the cables are connected securely, and then turn on the devices for testing;
  2. If you are using any network sharing device (router), please try unplugging the device and connecting your computer directly to our modem or wall-mounted network cable, and then carry out the testing.
  3. If the disconnection problem is time-related (such as getting disconnected at night only or more frequently during a certain time period), please record it for further processing when you contact us.
  4. If your network service is equipped with a modem, please check whether the modem's indicator light changes abnormally when the disconnection occurs. If so, please record it for further processing when you contact us.
  5. If you connect your computer directly to our modem and the disconnection problem persists, please check whether any unusual message appears on the computer screen when the disconnection occurs. If so, please record it for further processing when you contact us.

Internet speeds may be slow for many reasons. Please see the explanation below:

  1. The computer’s hard disk storage space and CPU speed are insufficient, which may cause overloading of the CPU and slow down Internet speed;
  2. Multiple programs are enabled simultaneously;
  3. Many users may be connected to the same server and downloading the same data at the same time. This will affect Internet speed if the URL cannot cope with the large number of download requests in time;
  4. If you connect to our broadband network through a USB port, the Internet speed will be reduced due to sharing of resources at the USB port (when the USB port connects to a printer simultaneously, for example); therefore, we recommend that you connect to the broadband network using an Ethernet card;
  5. If a wireless router or broadband sharing device is used and connected to multiple Internet devices simultaneously, the Internet speed will be affected.

No. Our system will automatically assign you the right information so that you can access the Internet normally.

We do not restrict the types or manufacturers of the devices purchased by our customers; therefore, your normal use of network services won’t be affected in general. However, the hardware specifications of the network sharing device may limit the network functions available to you. It is recommended that you inform the sales staff of the relevant information regarding your services before purchasing related devices, so that they can help you choose the most suitable devices.
