LAN with VLAN IPTV setup

[Algimantas]

Hello everyone.
I have a question about a network setup that I want to adapt.
My ISP provides internet and IPTV which comes from tagged VLAN6.
VLAN6 is then switched from my router to a IPTV STB which then connects to tv via HDMI cable.
The problem with this is that with this setup my tv's are offline. In order to connect them I can use either ethernet cable or wifi, but wifi signal near both of my tv's are weak so that's not an option. If i decide to use ethernet cable to connect my tv's then there will be a lot of hassle with the cabling.
Is it possible to deliver both VLAN6 and access to LAN via one port to another router which then splits vlan6 and delivers it to IPTV STB while other ports deliver access to LAN for tv's?
The reason I want to connect tv's to the LAN is that I want to watch content that is stored in the NAS.

For a better understanding of the situation, here is the visualization of the network that I want to make

Can you use Ethernet over power setup, have one adapter connect near main router and get only vlan6 traffic and second on Gala IPTB.

I don't really want to play with Ethernet over power adapters. These things are quite rare and expensive here in Lithuania.
What would happen if I connect 2 cables from RT-Ac56U to another router? One with VLAN6 and other with LAN ?
Another router is VLAN capable so maybe that would work?

I assume your STB's are right next to you TV's? How are your STB's currently connected back to your router?

I currently have only 1 TV but i'm planning to get another one. The current IPTV STB is connected directly from RT-AC56U with vlan6 and i get internet to TV via wi-fi, however rt-ac56U 2.4ghz wifi is extremely bad so i want to connect current tv with cable aswell

Ok so the STB is connected to the router with an Ethernet cable I guess. So you really only need a managed switch to be able to do what you want to do. A second router like you show may or may not work depending on its capabilities. If you don't really need a second router then I would use a managed switch. That way you can connect one trunk port from the switch to the router and pass both VLANs.

Yeah I guess a managed switch is the best way to go. Now the question is - is it possible to configure rt-ac56u to pass taggeg vlan6 and untagged vlan via one port?

you can because some ISPs use tagged vlan. If this is not possible via GUI you can configure this in the underlaying linux files. any semi managed switch should be able to use vlans.

In the case you cant you can use a semi managed switch to pass it.
