How Can I Set Up a Modem in My Room Using Ethernet Wall Ports?

It sounds like your house might already be wired for ethernet, which is awesome! Instead of connecting multiple modems, you might want to consider using a network switch. This way, you just need one main modem located where the internet line comes into your house, and then you can connect that to an 8 or 16 port switch. From there, run ethernet cables from the switch to each room, including yours. It'll keep everything simple and reliable without the hassle of multiple modems.

If you're unsure whether your wall ports are wired to the main network in your house, it might be wise to check. If they are, then your plan should work fine! Just keep in mind that it’s best to use network switches rather than multiple modems to avoid connection issues.

Using another modem in your room can lead to complications like double NAT, which can mess with your internet access. Instead, I’d suggest using a simple access point. Connect it to the existing modem using an ethernet cable going into your wall port, and that should boost your connection up to the second floor. Just make sure to set everything up correctly!
