Correct Port Settings for a Sky Q box?

Hi! Wondered if anyone could help.

I have a small home network, with a sky router connected to the phone line giving me 35Mbps broadband speed (no fibre here!). The Wi-Fi on this router is switched off.

I then have two GS1915 switches and two NWA50AX WAPs providing Wi-Fi coverage around my house, and hardwired connections to PS4, CCTV etc.

In the Nebula Control Centre, it seems to correctly identify the port connected to the router as the uplink port, and when I wander round the house, everything works fine - speed tests on mobile devices generally showing around 30Mbps.

This is until I plug a SkyQ box in to a switch.

As soon as I do that, my internet connection speed dies. In the Nebula Control Centre, it now identifies the Sky Q box as the uplink port, and when I walk around the house and carry out speed tests, I'll only get around 150kbps and nothing works properly.

Are there any settings I can apply to the switch port that will stop this happening?

    Hi @KezzFlan,

    I would like to know which device is the uplink in the first scenario:

    In the Nebula Control Centre, it seems to correctly identify the port connected to the router as the uplink port, and when I wander round the house, everything works fine - speed tests on mobile devices generally showing around 30Mbps.

    And the second one is the SkyQ box, right?

    As soon as I do that, my internet connection speed dies. In the Nebula Control Centre, it now identifies the Sky Q box as the uplink port, and when I walk around the house and carry out speed tests, I'll only get around 150kbps and nothing works properly.

    Is the SkyQ box a mobile router or? What kind of mobile router is it? An indoor model or a outdoor model?

    The first device is the router supplied by Sky - an SR203. This is truly the uplink and is connected to the telephone line for the house.

    The second device is the SkyQ box - with the satellite dish connected to it.

    I have now worked around my issue. I recabled some of my devices so that now, all Sky devices are connected directly to the Sky router, and then the rest of the house on the Zyxel network takes another port on the router.

    Everything now works perfectly.

    It definitely seems like Sky devices do not play nicely with third-party equipment! Still curious to understand why/what's happening, just out of interest.

    Hi @KezzFlan,

    This is more likely a multicast storm-related network speed issue.

    To resolve this, you can enable multicast storm control on all ports (recommend 100 pps). P.S. If you're willing to change your connection/topology again.

    If it does not help, we might need to check the port status and utilization or capture packets.
