[Solved] 2.5G Intel Ethernet Controller I225-V not working

Salam, Peace, Bonjour... and Thanks

I have installed Openwrt on a x86 machine which has 2 NICs.

As you see the first one is supported. But the Intel 2.5 Gigabit is not.

kmod-e1000e does not seem to work with Intel 2.5 Gigabit Ethernet Controller I225-V.

Is there any driver that supports this NIC ?

Supported by the igc driver. install kmod-igc

Thank you very much for the swift and efficient response. Working like a charm. Live a very long and healthy life. :')
