Hello, I have installed 5 Cat7 network cables in the house. They all start at a patch panel and then go to the network outlets.
The problem now is that one of them doesn't work. I have already replaced the outlet once and connected it to a different port on the patch panel. Each time, the tester shows that channel 8 is not working.
How can I identify the cause here?

Maybe the non-working socket is wired according to the B standard, while the rest follow the A standard, or vice versa?That would affect the whole pair, so if it’s pin 8, then also pin 7.https://www.instagram.com/11antgmxde/

Are you sure that a router will fall back to 100 Mbit if one conductor is broken? Usually yes, unless a specific transmission mode has been fixed.

Although I was wondering what happens if only a CAT cable is initially connected to the device at such a socket... since the outlet itself can’t perform negotiation.K

That would affect the entire pair, so with 8 it also applies to 7.Wire pair 7/8 (brown/white + brown) is the same for TIA 568 A and TIA 568 B, so it doesn’t matter here. My advice: borrow a Fluke DSP or similar tester, measure, and locate faults with an accuracy of a few centimeters.
I could help out if you are nearby (NRW / Münsterland).
