Orange light is meaningless - its just the 1p LED failing/fading over time and is not indicative of any issues. Only worry if it goes bright red = overheating Hub.
The reset button needs pressing in firmly for 60 seconds - try again.
But you havent said... are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection/Hub related?
