The gigabit ethernet on my asrock b450 gaming is not working. Wifi is fine. Network diagnostics says "ethernet doesn't have a valid ip configuration". Green led on, amber flashing somewhat slowly. I'm running windows 10 home 10.0.18363, bios: american megatrends p3.70, 11/18/2019, UEFI. Intel driver 12.15.184.0 8/4/2016. Same ethernet cable plugged into different computer works fine. Device Status: 0180200A [DN_DRIVER_LOADED|DN_STARTED|DN_DISABLEABLE|DN_NT_ENUMERATOR|DN_NT_DRIVER]

Other than that the system works great!
