hope you can help and apologies that I am not very technical.
We just had a new BT hub installed running off fibre to home broadband. We have the hub then connected via a CAT6 cable to a switch (as hub doesn't have sufficient ports and is in wrong place). From the switch we have another CAT 6 cable running through our house to a socket in wall to which we have then connected Apple TV 4K via another CAT 6 lead.
When connected like this the Apple TV cannot connect to the internet. I've spoken to apple and BT and I understand the issue is that the BT hub isn't giving the right permission through the switch for the apple TV to work and I've been told by apple that i need to get the hub to 'recognise the switch' as part of the network. When I spoke to BT they said this was a 'port forwarding' problem. I've tried going onto the advanced settings of the HUB to set up a port forwarding rule to the IP address of the apple TV using port 80 and a TCP connection. Still doesn't work. - I'm not sure if I've got the wrong port number as I haven't been able to understand how to find this out or if it needs to be TCP or UDP - I don't understand the difference! I also don't know how to recognise the switch IP address (or whatever needed!) if I need to make a change to permission for that - or what port number or type it would need to be.
Please help - in non technical language - am really stuck!? with kids at home I really need the apple TV to work!
Note - if I remove the switch from the system and plug home CAT 6 network cable direct into Hub it all works but that won't work long term, I need the ethernet connections to run through the switch to apple TV. I can also get the apple TV to work via wifi but again is not a long term solution due to wifi signal issues.
Desperate self isolating mum! Sarah
What model of Ethernet switch are you using, because if Apple TV uses multicast, then not all Ethernet switches are suitable? The TP-Link SG105 has this ability.
I found this via Google.
Apple TV will be able to stream content from the Internet to a connected display without multicast enabled. ... AppleTV uses multicast INTERNALLY on your network and needs specific multicast support to work because it does streaming between devices... like to an iPhone.
It is a 8-port gigabit desktop switch made by tp-link. TL-SG108S
yes it has IGMP snooping
Mac address learning
auto negotiation ports
auto MDI/MDIX ports
Then I do not know why its not working.
Have you disabled Smart Setup on the home hub, as that can cause issues.
