I have Hue Bridge that worked without any issues. Recently I bought set of TP-Link Deco x60s. Both bridge and decos are updated to the latest versions. The issue is that when the Bridge is connected to the main Deco, there is no internet and the hue is disconnected. When I use the same cable and power adapter and connect it to one of the repeaters ( Other Deco X60 ), the Hue Bridge have internet. I've tried both ports on the main Deco x60 and they're all working ( providing wired connection to my MBP, so physically the ports and the cable are working ).

The problem is that the second Deco ( that is working with the Hue Bridge ) is at very small place and there is single powerplug ( to small to add power splitter ), so basically I cannot use it. 

The weird thing is that If I put another router before the Deco and switch the Deco from "Wi-Fi router mode" to "Access point mode", the Hue Bridge is working from the main hub. 

I tried to switch positions ( ex. internet cable connected to port 2, Hue Bridge connected to port 1 ), tried different cable, nothing seems to work. 


EDIT:

It turns out it's my IPTV/VLAN settings. It is enabled in order to use Deco as main router and get rid of the ISPs provided router. The IPTV was enabled and set on port 2 of the main unit. I don't use my ISP provided IPTV ( still needed to set the VLAN settings ), so just changed the settings of the IPTV to different port on different unit. Leave the post here in case anybody freaked out as me with the same problem.
