Help - lag and screen tearing on ROG B550

Hello,

I need some opinions/help with my setup. I am using a ROG B550-E motherboard for my host, which has the 2.5gbps port. I am connected to my router which also has a 2.5gbps port. However, even though my LAN connection is solid on paper, I get 12-18% loss on network jitter.

I checked this with our friend chatgpt, and it told me that the ROG B550 was using a faulty network hardware, the intel I225-V.

Does anyone know about this version of network card or anything I can do to solve this problem? I'm currently debating if I should just get a new pcie card for my motherboard.

PS - I was actually using a MSI B550 on my host machine before and it was working flawlessly for streaming even though its a 1gbps port.
