Hello, i'm using NanoPi M4 + SATA Hat + 12V, 2A PSU. I'm pretty happy with it, but today i have tried to relocate this setup to another place using a 5 meters ( CAT 5e) long network cable. But network card won't start. I have tried 4 another cables -> the same thing. It works only, if the network cable length is less or equal than 3 meters.
On monday i want buy a CAT 6 network cable and try with it. But my question is, is there any limitations known for network cables on NanoPi M4?

Update:
I have bought new CAT 6 network cable. I can confirm it works ( 5, 10 m ). But all Cat 5e cables works now too.
Nothing has been changed since saturday on this setup. Very strange thing....

Update 2:
I figured it out. I have an Netgear GS108E-300PES Switch (Smart Managed). It has randomly blocked port. I dont know if switch was faulty or maybe it was related to RK3399 TCP/UDP-Offloading issue in combination with managed switch (
https://github.com/MichaIng/DietPi/issues/2028).
But i have replaced the switch and disabled TCP/UDP-Offloading on M4. It works now as expected.
