Hi all, I'm trying to set up IPTV to work on TP-Link TL-WR841N/ND v8 running OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-149-g0d8bbd2 Release.

First, I had a problem with a power failure and my original WAN port stopped working. I changed the WAN port to P1 and have set up 2 separate VLANs for networking. Vlan "LAN" is used for all home devices and vlan "LAB" is used for my server.
On Port 4 I want to set up my IPTV (needs to be on vlan ID 35) however if I tag port 1 (wan port) the TV works, but the rest of devices do not have Internet connection.

Bellow a short summary of my switches:

VLAN ID CPU Port1 Port2 Port3 Port4
1 tagged untagged off off off (wan)
2 tagged off untagged off off (LAN)
3 tagged off off untagged off (LAB)
35 off off off off untagged (IPTV)

My network config file is the following:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'

No one has any options for me to try? I'm really stuck here.

Many switch chips do not support simultaneous tagged and untagged operation on the same port. I think the Atheros chip in your router is one of them.

If your modem is really running tagged and untagged packets on the same cable, an inelegant workaround is to put an unmanaged switch between the modem and the router. Connect the TV box(es) to that switch, so they have direct access to VLAN 35 from the modem.
