Hi. I have a strange problem. I have a 5 port tp link network switch that works fine with the bt box but needed more ports so i got the same tp link 8 port switch and now the bt box cant receive my subsribrion channels and bt sport???
If i put the 5 port switch back on it works???
They both support IGMP snooping function, so they should work. What happens if you do not connect anything else to the switch, just a single input and output?
What else are you connecting to the switch, that may be upsetting the IGMP snooping?
Have you tried a power reset on the switch after its connected up, so it initialises correctly?
As @Keith_Beddoe says they should both work but in truth almost any switch should work but those that support IGMP Snooping prevent all the other devices on the network from being flooded with the multicast transmission.
WIth the 8-port in place do all the other connected devices see the internet and does the Youview box get the catchup players?
I'd also try a reboot of the Hub & the Youview box as that can sometimes set things straight with the BT TV Subscription channels.
You've started referring to "access point" , so just how is this all configured? Not using powerline adapters from the hub to where the Youview box is or something similar?
What if you connect the 5-port as normal and then try the 8-port plugged into the 5-port with the YV box then plugged into that. Just a test not permanent.
I can't see why there should be any difference in the behaviour of the 2 switches unless the 8-port has a fault.
