You write: Looped through with VLAN.
Passed through what kind of devices exactly?

By the way, if you had a really functioning VLAN configuration, you would not need IGMP or other multicast settings on your “additional equipment”.
However, since you are still having problems with the live programme, this actually indicates that neither your VLAN nor your multicast settings are working correctly 🙂

It would be best if you could also describe your complete communication chain from the Swisscom Internet box to the Swisscom TV box with all the network devices connected in between, which would then greatly improve the possibilities for tips and specific advice.

Where do you see problems with your internet connection?

For a g.Fast connection with a medium-length residual copper line, your diagnostic values for the Internet connection are completely normal.

Since the Swisscom Internetbox itself does not support VLAN, two LAN cables are required between the Internetbox and a downstream VLAN-capable network device, one for the normal network and a second for a separate LAN input of the downstream device, so that this specific LAN input can then be defined and used as an input for the VLAN.

Have you wired the connection between the Internetbox and Dreambox correctly with two LAN cables?

The SNR is exactly where it should be for a g.Fast connection, because the mCAN, which serves your Internet box with g.Fast, uses it as a brake pedal in the event of faults.

Approx. 6 dB means = Full Speed, which is what the line provides.
However, if there is too much interference at full speed, the mCAN gradually increases the target noise ration, first to 9 dB, then to 12 dB, and so on, thus reducing the connection speed between the mCAN and the router more and more.

And as a follow-up question:
Are your two TV boxes of the same type, which one exactly, and have you ever swapped them for each other?
If you have already swapped them, does the error travel with them?

Fliofreivo63 Yes, optimisers are known to interfere with domestic installations. But these are very rare cases. You can test it now in the dark by de-energising the entire solar system. The battery will also be empty at this time. I have no optimisers (unnecessary for inverters with shadow management) and absolutely no problems. Also check in the home network that you don’t have any loops in there. Otherwise you can send me your details by PM, then I can take a closer look on Monday.

Fliofreivo63 I haven’t changed the TV yet, but everything is up to date and integrated into the network.

If the two TV boxes are connected to the same switch, simply swap their LAN ports on the switch.
If the live programme is then running on the other TV box, this would mean that your blue TV VLAN is not tagged on both LAN ports.

You once wrote about a UniFi Dreambox in one of your earlier posts, so the basic question will be what your goals are for your home network:

• Variant 1: Internet box as sole router, operation of a sole all-in-one network, everything as plug&play as possible
• Variant 2: Cascaded router behind the Internet box (in your case probably the UniFi Dreambox), operation of 2 separate networks, reduction of the Internet box to the functions of Internet access, telephony and possibly direct supply of TV boxes. Own hardware for all other services, i.e. router incl. switches and WLAN access points incl. complete self-administration of your own core network

If I have understood correctly, does the TV box have its own cable?

Then I would connect it DIRECTLY to the IB and leave out everything else.
