Hello,

I would need some help on how to arrange this so that everything works.

The situation is as follows:

• I have an fiber from ISP on the 1st floor, enabled on the modem. I have Wi-Fi enabled on the modem to cover the 1st floor

• The 1st floor and the basement are connected with a UTP cable

• The UTP cables then go from the basement to the 2nd floor

• In the basement and the 2nd floor I have 2 switch TP-link SG108E

• All devices connected to the switches (PCs, IPTV STB) works normally

• Since I do not have a good Wi-Fi signal in the basement and on 2nd floor, I purchased 2 Deco Mesh X50 units

I connected the Deco units to the existing setup, each on a separate switch (picture 1). In this case, Deco1 works normally, while Deco2 works in the Mesh only via Wi-Fi connection and not via ETH. Since there is one floor in between, of course Deco2 is almost useless.

But if I make a small change (picture 2), the connection from the modem goes first to Deco1 and then to the switch. In this case, Deco2 also works via ETH connection and WiFi works great. The problem is, with such a setup, the IPTV STB in the 2nd floor does not work.

I assume that it will be necessary to somehow configure the ports on the switches. Does anyone know how?
