I forgot to add some important information so I'll add it in this comment. The USB-Hub I'm looking at buying is a relatively cheap one I found on amazon which claims to have "fast" connects but I'm not too versed in what is considered good or not, you can look at it here. My internet connection with my ethernet adaptor is 876.3 Mbps download and 539.6 Mbps upload, you also look at the ethernet adaptor I'm using here.

TL;DR:

Read the bolded text. 🙂

Hello,

I'm using a Surface Book 2 Laptop and I need some additional ports for my keyboard, mouse, and ethernet adaptor so I'm going to be getting a USB-hub which has decent bandwidth and four USB ports. I have two open standard USB ports as well as a USB type-c port that is connected to a HDMI adaptor which connects to my monitor. My question is, should I connect my ethernet adaptor to my USB-hub? I'm aware that USB-hubs can have performance impacts and I want to have really good internet connection so when I join video meetings I don't have lag spikes which I get with wireless connections, and just for everything else internet related. As I mentioned, I have two 'standard' USB ports open so I could have both my USB-hub and my ethernet adaptor connected, although, that would mean I have to connect and disconnect three cords (USB-C to HDMI, USB-Hub, Ethernet Adaptor) as opposed to just two (USB-C to HDMI, USB-Hub) which might seem incredibly lazy of me but I use my laptop as a desktop and a portable laptop frequently so I just seems so much more convenient to have this option. Please let me know of how much of a performance impact this will have, I will gladly take performance over convenience.

Thanks Redditors!
