Swisscom problems

NilsL · 17. Jan

@Fliofreivo63 Could you tell us a bit more about your VLAN setup?

Could it be that your switch can’t handle multicast correctly or multicast and IGMP are not configured or not for the Swisscom VLAN, that would explain why Live TV doesn’t work but replay and recordings and the apps do

I’ve already tried this, and everything is correct. IGMP is activated and so is multicast

I have already tried this, or rather looked at it, everything is correct. IGMP is activated and so is multicast

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.

@Werwolf Thank you, I have now noticed other problems

Werner I tried before via WLAN, but it doesn’t work there either!

In other words, I left out the Dream Machine from Unifi. However, the fact that the lower TV works and is also connected to the same switch, or is also connected to this VLAN, speaks in favour of this.

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.

Fliofreivo63 · 17. Jan

Werner

e.g. the SNR is actually very low, or rather I only have 60Mbit/s in upload, whereas I would have a subscription for 300Mbit/s.

Werner · 17. Jan

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?

Fliofreivo63 · 17. Jan

Werner

Yes, everything is done like this, two lines from the IB3 and then one as a supply line and the other for the VLAN, accordingly created a VLAN in the Dream machine and then tagged these ports, which are needed for it.

Werner · 17. Jan

Fliofreivo63

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 · 17. Jan

Werner

Yes, of course, sorry, the greater the damping, the lower the speed….sorry, that should be obvious. (I’m an electrician)

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

What I also find strange is that we had a power failure, where we still had the IB2, which kept hanging up after the power failure. That’s why we now have the IB3, but unfortunately I still have these problems, but nobody from Swisscom could give any information, the router has been reseted umpteen times, but nothing works. What I am now noticing again is that the WLAN also has problems again and again, i.e. the connection drops out. I also find that very strange! I’ve read that solar systems cause problems even with small quantities. I also have such a system at home, with optimiser, battery and emergency power, plus 3 inverters. Could it be that certain frequencies also lead to problems?

Roger G · 17. Jan

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 · 17. Jan

Okei, thank you, I will look into it. What also happened four times before was that I got messages on the Unifi UI that I had a latency of 25ms, which suggests to me that the network is overloaded. But I don’t know why.

Werner · 17. Jan

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.

Werner

Salü, sorry for the late reply!

I was thinking of suggesting to my flatmates that they redo the entire internet as we also have no Tt83,

Which managed switches would you recommend, or which access points? Thank you

Werner · 22. Feb

Fliofreivo63

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

cybi · 22. Feb

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.
