I have a Dell Latitude 5420 laptop with LMDE, running kernel 6.1.0-12. This laptop has a builtin I219-LM ethernet controller that I can see via lspci. Some research indicates that this needs the e1000e kernel module, so I grabbed it from Intel, compiled it, and installed it. There were some complaints during the compilation, but nothing more than the average compilation process. Plus, it shows up in lsmod. Afterwards, lspci -vv
displays it with the e1000e driver:

However, when I do lshw
, it is listed as unclaimed:

...and of course, it's still not showing in ifconfig. So, where do I go from here? Did I miss anything obvious?
And just for the record, I know that the ethernet port is working. It worked fine in Win11 before wiped the PC completely.
Yup. Its landing speed is pretty much also its stall speed. Practically no margin for error.
