Unidentified Network - Ethernet

So.... a few weeks ago my network suddenly didn't work. It was written Unidentified Network - No Internet connection. I've tried everything but it didn't work, so I bought a network pci card in order to fix the problem, and it did. BUT a few weeks later my ssd died and I bought a new one. Reinstalled Windows, and guess what, both the MB port and the network card don't work.

Sometimes the MB port is working for a few hours and then disconnecting again.

*Windows troubleshooter says: "Ethernet" doesn't have a valid IP configuration.

WHAT TO DO???

Are there other devices on the network and do they work fine?

Router:  Intel N100 (pfSense) WiFi6: Zyxel NWA210AX (1.7Gbit peak at 160Mhz)
WiFi5: Ubiquiti NanoHD OpenWRT (~500Mbit at 80Mhz) Switches: Netgear MS510TXUP, MS510TXPP, GS110EMX
ISPs: Zen Full Fibre 900 (~930Mbit down, 115Mbit up) + Three 5G (~800Mbit down, 115Mbit up)
Upgrading Laptop/Desktop CNVIo WiFi 5 cards to PCIe WiFi6e/7

Yeah. I have another device connected to the same router ( I have a few Ethernet ports around the house) and it works just fine.

you haven't  got a device with a conflicting IP address have you?

That can sometimes do bizarre things...

I have no idea... But in addition, the light indicator on the pci card is green (good).
