When I first installed HiFiBerryOS, I did not have a wired connection handy and so configured it as wifi. Now, with the device in it's final location, I can attache a wired lan and would like to eliminate potential issues with wifi.
Just connecting the wired device did not seem to have the desired results. The Network/Wired display shows it connected, but it did not run DHCP and so did not get an IP address. I then configured a manual/static IP address, but still the device cannot be accessed or even pinged on that IPaddress. I have tried various combinations of rebooting and disabling wifi, and still HiFiBerry OS will not use the wired lan nor does it seem to fully bring it up.
With a static IP address programmed, ifconfig shows:
eth0 Link encap:Ethernet HWaddr DC:A6:32:B3:8A:20
inet addr:192.168.1.22 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::dea6:32ff:feb3:8a20/64 Scope:Link

which seems to indicate traffic - albeit unsuccessful traffic at some layer.
