Tp link deco m5 not in the same network as router
Let me start by saying I do not know a whole lot about networking. I will try to explain the setup and issue as good as possible.
The internet enters my house and goes directly to a modem router. From there I have a utp cable running to one deco m5 and from that deco runs another cable to a second deco m5. This ensures that I get WiFi access through the entire house. My pc is connected with a utp cable running from deco m5 nr2.
Now, my television downstairs is connected to the modem router downstairs with a utp cable. The problem is that I can't seem to access my Plex media server (running on the pc) from my tv. However, when I switch my tv to WiFi (from the deco's) it directly finds my Plex library.
This tells me that the WiFi from the decos is not directly connected to the wired outputs from my modem router. Is this expected functionality of the decos or might there be something wrong in the settings of my modem router or the decos?
The decos itself only have two utp ports so I don't have any options there (one is occupied for in and one for out).
Hoping someone is able to make anything out of it. Thanks in advance.
