TalkTalk introduced a bunch of multicast stream internet channels to their YouView box for free recently, but I, like a whole bunch of others have had various issues with the IPC6023 error and apparently by the number of topics on forums the support teams have no idea why or how to fix it. I’ve discovered how, through the power of reading everything ever.
What the issue seems to be is IGMP settings – some routers have a setting for this, others use a proxy. I don’t know exactly what it is or does, but it has something to do with multicast streams (my router told me).
To fix it, what you need to do is either:
Change your IGMP settings to be type 1/2 for ADSL
Change your IGMP settings to be type 3 for FIBRE
Enable IGMP Proxying (usually this is a check box that says “Disable IGMP Proxying” you want this UNCHECKED.)
These will be options inside your router (192.168.1.1 or 192.168.0.1 are most common), depending on the make and model. Usually under WAN Settings. Google will be helpful here!
I’ve spent hours on phones and using their live chat to be told to reset routers, the YouView box itself and more all pointlessly. Hopefully this will help others.
