Boost Wifi7 10G port flashing orange

I recently had 3G internet installed with a new NAH and Boost Wifi7 hub. The hub is connected to the NAH through the 10 Gbps port (or so the installer told me). 

When I connect by ethernet to the 2.5 Gbps port I am only seeing 1 Gbps speeds. The 10G port on the hub is flashing orange, whereas the 2.5 Gbps and 1 Gbps ports are green. 

What does the orange flashing mean? Am I not getting full 3G speed to my Wifi hub?
