IPTV on TL-WR841N V11

I am having trouble with setting up iptv on this router. In Network -> Switch I have no wan port, so I am trying to turn lan1 port to wan. I add a second vlan with port1 and 2 set to untagged, set to off in vlan 1 and cpu on both vlans set to tagged. In interfaces I change WAN to eth 0.2 in physical settings and also copied the mac address from my isp's router. After that, when I plug the isp cable in port 1 I have no internet.

What am I doing wrong? Should the cpu be tagged on both vlans? I managed to do this on a v9 wr-841n a while back, and it worked first try, but it looks like i've forgot how it's done.
