this problem, which I had solved long time ago, reappeared: Using suspend and wake-up my system Ethernet is not working an the network manager shows:Linux Mint 19.3 Tricia
(but the cable and router are plugged in and working). I also tried another Ethernet cable, no change.cable removed
Searching for a solution, none of the tips worked. Some recommend to upgrade the Ethernet card driver, but I am not able to compile the drivers from Intel. My card is:
Intel doesn't provide a ready to install driver package, just the source for compilation.Intel Corporation 82567LM Gigabit Network Connection (rev 03).
I also looked up the tips for the power-management (ACPI), but found no solution.
I found that the logical name is "enp0s25", but neither "ifup" nor "ifdown" is working. Using "ifup eth0" I get the error: "Unknown interface eth0".
I'm really lost. Any ideas?
NB: WLAN works perfect, but I prefer Ethernet cable connection on this PC.
