Hi to all.
This is my scenario:
An RB2011UiAS-2HnD-IN configured as router (port 1 & 2 are for ISP, failover mode) and DHCP server
an unmanaged TP-Link switch and some TP-Link routers configured in bridged mode (as AP).
I have two smart TV that would use netflix/youtube (One over Wifi and another by LAN)

I don't know much about VLAN, but I'm pretty sure I can't use VLAN because the unmanaged switch, right?
So the TVs would have static IP.

I will limit bandwidth usage (I know how to do this on the routerboard) but also want to isolate those IP.
Any hint?
Thanks in advance
