[Question] How to isolate my TV from the network? (lemmy.world)

Hi Guys,

Need your help. I have a router to which all th devices are connected. Mostly wireless but the TV is connected via LAN cable. I have installed few apps on the TV from not trusted sources and I dont want the TV on the same network. How do I isolate the TV from the network so that it can still access the internet but cannot see anything on the network. Hope it makes sense.

How it's implemented can vary, but you're gonna take one of three approaches

  • Microsegmentstion - On a home network this is the hardest but ensures there's no overlap
  • Separate VLAN - this is usually good if your router can support it and have multiple gateways for each VLAN. Your router can then restrict traffic. Unifi gear does this well and I use this set up to segment my guest and IoT traffic
  • Separate subnets - if your router doesn't support multiple VLANs this can work, but you still need a router that supports it

The latter two can actually work with an unmanaged switch as long as you tag your vlans correctly. The key is having a router than can handle it.
