Understanding the Ping test results

  • Request timed out or No ping replies: This indicates no connection at all to the Smart Hub. Check that you’re connected to the right Wi-Fi access point, with the correct password, and that you have adequate signal strength.
  • Packet loss or large latency (time=200ms or higher) in the ping replies can mean poor signal strength or interference is affecting your connection.

Check your location and surroundings

Wi-Fi signals can be weakened by certain building materials, such as concrete or steel, or disrupted by electronics, such as televisions or stereos.

To ensure that your Wi-Fi signal is not compromised, we recommend that the following objects not be located within 8-10 feet of your Smart Hub:

  • Televisions
  • Stereo or Computer Speakers
  • Cordless Telephones and Stations
  • Other Routers
  • Computer Monitors or Tower
  • Bluetooth Devices
  • Microwaves

We recommend that your Huawei Smart Hub be placed on an elevated surface such as a table or shelf in order to maximize the range of your Wi-Fi signal.
