IB4 other (higher requirements) on switch?

    • Until I switched to fiber optic, I was using an IB2.

    With the advent of fiber optics, Swisscom gave me an IB4 as a gift 😁.

    My network is not particularly complicated and consists of two switches in addition to the router.

    • Netgear GS116Ev2 (16-Port Gigabit Switch)
    • Netgear GS108Ev3 (8-Port Gigabit Switch)

    DNS, DHCP are taken care of by our own server. The IB4 is only used as a gateway.

    Since the IB4 I have noticed more often that the picture and sound of the Swisscom TV-Box 5 start to stall and are interrupted after a while. Usually all you need to do is click on pause and after 5 seconds on play again. But the whole thing is independent of live TV and replay. I sometimes have to repeat the procedure several times.

    But the problem doesn’t always occur and I never had any problems with the IB2.

    The network path was as follows:
    IB2 -> Switch -> Switch -> Swisscom TV Box 5
    IB4 -> Switch -> Swisscom TV Box 5

    The two switches are of course quite old and the technology has not stood still.

    Could it be that the switches no longer work properly with the IB4? (IGMP Snooping is of course enabled and Validate IGMPv3 Header disabled).

    Maybe someone has similar experiences or tips on configuring the switches?

      The IB4 does not have any higher requirements for switches, but the TV-Box 5 does.

      While IGMPv2 was sometimes sufficient for older TV boxes, a functioning IGMPv3 is now required for the TV-Box 5.

      In addition, the TV-Box 5 can currently generally react more sensitively to older switches and work is therefore continuing to further reduce possible switch incompatibilities.

      So first of all, improve the multicasting and if that isn’t enough, connect TV-Box directly to the router (or if your hardware can “patch through” a VLAN), or alternatively replace the existing switch with a new switch that is fully multicast-capable.

    Hello @heuby

    Activate IGMPv3 again.

    The switches must be able to multicast.

    Swisscom has a Netgear switch, there is a config there.

    What may also be possible is to configure a port ondly.

    Thank you for your information.

    I’ll try to implement them and then let you know.

    I’m just surprised that the problems only started with the IB4. But it doesn’t matter. I have now received some valuable tips.

    Another question, how far is the TV-Box/5 from the Internet box? If there is only a lightweight wall in between, you could also establish a connection with the existing WLAN from the TV-Box/5.

    The prerequisite is, of course, that the WLAN in the Internet box is switched on and is set up nearby.

    Some users who needed WiFi in a remote room had to use the WLAN-Box at the link below and you could also plug in the TV-Box there, like a switch.

    I’ve tried a few things in the meantime.

    • Swisscom does not provide configurations for the old Netgear switches. Configurations are only available for the new ones from TP-Link.
    • Adjusting the parameters didn’t help. Stability is still not present.
    • The TV-Box is only about 5m away from the router as the crow flies without any major obstacles, but that’s not really stable either.

    Finally I pulled an additional cable from the router to the box. That seems to be the solution. In any case, the connection seems stable since then.

    Thank you all for the valuable information.

    A distance of 5m from the Internet box shouldn’t be a problem for the TV-Box’s own WLAN, I myself have a second TV-Box which is 8m away and a plaster wall in between with the TV-Box’s own WLAN connected to the Internet Box/3 and no problems .

    You can see the WLAN connection quality under Settings (gears) at TV-Box, at System and there Overview.

    Everyone here in the forum has probably noticed by now that this works for YOU 😉. However, you should not conclude that this must be the case everywhere else. External interference, structural conditions, variances even between individual devices of the same series - a lot of things are simply unpredictable when it comes to WLAN. The original poster has now gotten to the point where he has pulled a cable, which is always the best solution, especially with TV.

    Have you tried turning it off and on again?
