Zorin 17 Pro fresh install - barely working ethernet

Hi all. I've just installed Zorin 17 Pro and my ethernet connection keeps trying to connect and failing. Rarely it manages to do it but then drops off after a bit. My wifi is working better since I changed the automatic DNS to 8.8.8.8,8.8.4.4. Applied the same to the wired connection, but no improvement. The wifi connection works better when I have the wired one turned off.

I was having the same problem with Zorin 16 Pro and Ubuntu 24.04 before that. However my Windows 11 machine works fine with both wireless and wired connections. I should add that both machines ethernet cables are connected to this network splitter adapter (https://www.amazon.co.uk/dp/B0CHJD52LH?ref=ppx_yo2ov_dt_b_product_details&th=1), but since the Windows machine works ok with it, I assume it might be a problem with the Linux distros configuration. Any help at all would be appreciated.

sudo lshw -c network returns the following:
