ᐅ Flush-mounted SAT socket: Modem not working. Frequency filter?

Hello.
We have purchased a flush-mounted satellite socket[1]. The coaxial cable comes up from the basement to the next floor and then connects to this socket, where the cable modem is plugged in from the outside.
If we manually connect the cable from the basement directly to the modem cable, it works. However, it does not work when going through the socket. We tested two sockets, and neither worked.
Is it possible that there is a frequency filter inside that only allows TV frequencies to pass, but not the spectrum needed for the cable modem?
If so, what kind of socket would we need?
Thank you very much!

There are end outlets and distribution outlets, each available with different attenuation levels. The system is not as straightforward as a satellite distribution or the distribution of a terrestrial rooftop antenna, because, as mentioned before, neighboring houses are also connected in the chain. Additional or different outlets can be connected, but they must be the correct ones. For this reason, the cable network operator usually handles this themselves.
OK.
To avoid issues with filters/dampening, it is best not to use such a junction box, but simply an F-connector coupling [1] for the two cables. This then acts as just a cable extension.
Does anyone happen to know if something like this is also available as a (flush-mounted) outlet?
Thanks.

My question to the experts here is whether this can even work. Don't you need a special outlet for cable TV?

We bought a recessed satellite (SAT) outlet box[1]. The coaxial cable comes up one floor from the basement, then goes into this box, where the cable modem is plugged in from the outside. I can’t make sense of the item number without knowing the type of outlet. But if this box is truly a satellite outlet, it filters out return path signals from the F-connector and only passes satellite IF signals from 950 MHz upwards. That means it won’t work for your purpose.
By the way, the “ZZF” was a federal authority for broadcasting regulation that no longer exists. The federal eagle imprint is now just decorative and meant to impress non-experts.

If yes, what kind of outlet would we need? In any case, you need a cable TV (CATV) outlet that meets the specifications of your network operator (KNB):
- Future-proof with a wider CATV frequency range than the older usual 862 MHz limit
- If your provider is Unitymedia, possibly a four-port modem outlet with two F-connectors, so that a Horizon box can also be connected
Whether you require a directional coupler pass-through outlet with a termination resistor or a drop/single outlet depends on the design of the broadband distribution cabinet. This depends on signal levels and can’t be reliably answered remotely. This is a task for your KNB’s installation partner, who will select the outlet to ensure compliance with the standard signal level windows.
Since the term “end outlet” came up in a post: drop or single outlets are often mistakenly called this. True modem end outlets are pass-through outlets internally terminated with a resistor, such as the AXING BSD 963-11 or WISI DB 09 M 0650 models.
