Should I connect my PC directly to my modem or my router for Ethernet?

Thanks for the tips, everyone! Seems like I have a couple of options. I'll try both out and see which gives me better performance. Appreciate the help!

It's mostly about convenience! Whichever is closest and easiest to plug into is usually fine. I personally prefer connecting to the modem for a potentially smoother connection, but both options should work. Why not just plug it in and see which one performs better for you?

You can plug it into your router for possibly more stability, or you can try the modem if that seems better. Honestly, either option should work, so just see which one feels right.

You can connect your PC to either the modem or the router, but it really depends on how you have them set up. If your ISP device is configured to only allow your TP-Link to connect, then your PC plugged into the modem might not even access the internet. But generally, using your router gives you better security, so that's usually the better choice.

If your modem is purely a modem, then you'll need to connect your PC to the LAN side of your router instead. The modem usually only supports one device unless you have special setups like link aggregation, which isn't common. If both your modem and router are multi-functional, plugging into either could work, but I'd recommend configuring the second router to bridge mode for seamless access across the network.
