1. Check that you are connected to a Thunderbolt 3 port. This adapter will not work on a USB-C port that is not Thunderbolt 3.

2. Update the Thunderbolt software on your Thunderbolt 3 computer.

3. Update your motherboard BIOS or UEFI.

4. Update you OS to the current version.

5. If it is still not working, check whether your computer's Thunderbolt 3 port supports 15W devices or how many 15W devices are supported. The Sonnet Thunderbolt 3 to Dual DisplayPort Adapter requires 15W. Some computers provide 15W on only a limited number of Thunderbolt 3 ports.

For example, MacBook Pro (15-inch, 2016) and MacBook (13-inch, 2016, Four Thunderbolt 3 Ports) can power two devices that use up to 15 watts, and two more devices that use up to 7.5 watts. It doesn't matter which side of your MacBook Pro that they're connected to--power is delivered on a first-come, first-served basis. MacBook Pro (13-inch, 2016, Two Thunderbolt 3 Ports) can power one device that uses up to 15 watts and one device that uses up to 7.5 watts.
