The orange light for the UniD is normal. NTD boxes either show orange or green light for the UniD. As long as it's lit it means that it was able to detect an equipment to the said port.
I can see that you have been assisted by our Technical Team already. From what I gathered, it appears that it was taking time for the router to configure automatically. Nonetheless, after adjustments made by our Technical Team, your router started working.
Should you have other questions or concerns, please let us know.
