Gigabyte B550M S2H Ethernet adapter not working

[mar.ste]

If I plug the cable the system sees it:
[ 8690.861361] r8169 0000:04:00.0 enp4s0: Link is Down
[ 8702.078593] r8169 0000:04:00.0 enp4s0: Link is Up - 1Gbps/Full - flow control rx/tx

But no address is given by the router:

I tried many times to restart the system and even trying some changes on the router with no success. The wired RaspBerry 5 on the side is instead working properly.


For information, looking for solutions I've seen on internet a similar problem (with no answer anyway): https://askubuntu.com/questions/1530...ine-on-windows

How much is your time worth dealing with poor quality ethernet chips? The B550 usually has 2.5Gbps ethernet, so perhaps using the correct driver would be the first thing to try? I don't know about Gigabyte B550 motherboards. Gigabyte is Linux-hostile. Once I realized that, I stopped giving them money.

Or you could set a static IP .... or spend $25 for an Intel NIC and be done with it.

FWIW: While doing some research on AM4 systems, I discovered AsRock B550 has intel chips

The hardware report above says it has a Realtek 8111H GigE NIC.

There are multiple models of AsRock B550M motherboards. I know that the Asus B550 Gaming uses an Intel i211 NIC, but Asus is NOT the same as AsRock. https://pcpartpicker.com/products/co...LKLwrH,G6VG3C/ shows all of them use Realtek NICs. Some are 2.5Gbps and some are 1 Gbps.

I filtered based on AsRock and B550M. None use anything except Realtek wired NICs in that filter. Too bad pcpartpicker doesn't allow actually filtering on NIC vendor. Of course, pcpartpicker data can be flawed.
