MacBook Air ethernet stops working

I have a 2020 MacBook with Intel CPU and macOS Ventura (currently). I've recently bought a unitek D1026B hub. I plug the ethernet from xiaomi 4a router WAN port to the hub, and the hub to my laptop. When I use my work laptop with windows it works fine. When I switch to using macOS, the internet shuts down (especially when I start some games like League of Legends). In the options it indicates that the connection is fine (green dot) but I can't connect to any website. This issue has been occurringfor 2 weeks now and I haven't found anything that would help. Things I've tried: - change ethernet cable (2 different ones and works fine with windows) - downloading special drivers for hub - rebooting Mac or router (several times) -remove and add back the ethernet device in network settings -using sudo ifconfig en4 down/up (to restart network device I guess) -changing location in network settings -connecting directly from socket in walls (I live in dorm) and skipping router -downgrading from macOS Sonoma to Ventura -booting in safe mode (still lost connection) -renew DHCP lease (it won't even get correct ip address) From all of this I think it is some MacOS issue but I don't want to downgrade it even more and don't know how to solve it. Also I can't change Hardware settings in network settings I can only switch from automatic to manual but when I switch for example speed it won't save. After I downgraded to Ventura it was okay for about 2 days but after that time it started "crashing" again. My dorm officials require to use DHCP so I can't use static IP or DNS. Does anyone have any idea how to track the issue and how to solve it?
