Dear,

I do have 2 deco M5 units, in a daisy chain configuration. Both units are connected by a LAN cable, in order to ensure ethernet can be used as a backhaul. 

I do have a TV located close to my slave unit and I have the IPtv receiver (set-top-box) connected with a LAN cable to the second port on the slave unit.

In order to get my TV signal right, I did activate the IPtv bridge mode. According to the TP-link support article, when IPTV is configured, the IPTV service only takes effect on the other Ethernet port of the main Deco. Other wired network clients or switches won’t have internet access when connected to this Ethernet port on the main Deco.

I have 2 questions:

1. Is the ethernet connection still being used a backhaul once I do activate the IPtv bridge mode?

2. Is there a way to activate IPtv on the slave unit?

My goal is to get the IPtv working well, while ensuring the ethernet connection between both my M5 devices is still being used as backhaul.

Thanks for any suggestions!
