They're only all blue if you have enabled 5GHZ mode. In the standard 2.4GHZ mode the lights are green. On my superhub 1 the top light goes blue and the other 2 are green. The blue light at the top denotes it's connected to VM and the other 2 lights denote signal ok and data transfer active. The light in the middle is solid and the bottom one flashes with the blue light at the top when a connected device is actively sending and receiving data wirelessly. The blue light stays solid when a wired device is using the connection through a ethernet port on the side. Normally if the light in the middle is not solid, this would suggest the router cannot lock onto a signal from the vm cable going into the back. Does it still work ok?
