DO THIS FIRST.

Things to Note Before Getting Started

Please check the following conditions for a successful set-up:
You have selected a 2.4GHz Wi-Fi network. The hub does not
support the 5GHz option. Select the 5GHz band instead of the
most common mistake when setting up the hub for the first time.
Your Wi-Fi must not contains space or other special characters.
Place your hub as close as to your router when setting up.
A slow network speed will also affect the performance of your hub.
It is recommended that you have an upload speed of at least
2Mbps or faster.
Make sure that the AP isolation setting in your router is disabled.
If using 3G/4G SIM card, make sure the 2G network of your service
provider is still available in your country. You should purchase the
hub with 3G/4G cellular communicator if the 2G network is
unavailable.
