Hello! The issue is that I share an apartment with a common internet connection. The router isn’t reachable from my side, and there’s no physical cable inside the walls, so I’m using Wi-Fi alone. This affects streaming games through Steam from my bedroom PC to the TV. I also don’t want to expose my NAS setup on the network due to privacy concerns. My idea is creating a private internal network within the building—direct connections between my PC, TV, NAS and other devices without going through the Wi-Fi router. I have a Pi-4 with an Ethernet/USB adapter and a basic switch nearby. I’m thinking of using the Pi as a router and linking everything via the switch. Is that feasible? Also, could I connect the Pi-router to the downstairs Wi-Fi so my devices can reach the internet through it? Not sure if these suggestions make much sense. Appreciate your time!
This is such a massive security issue I can’t even attempt to explain it. Are you able to see other machines on the network..? Or are they set up as every client is not able to see other machines, which would imply it’s set up as a guest network? If it’s a guest network, that isn’t a security issue, but if it’s not a guest network, that’s horrible….
The task is straightforward with various routers, focusing on one that functions as a wireless client. I prefer Mikrotik because of its flexibility, though some setup skills are required. You'll need at least two routers or one equipped with dual Wi-Fi. The first router should be configured as a wireless client with a DHCP server on the wireless port, connecting to your landlord's access point. Then, you can establish a private network on the wired side. It’s crucial to set the wireless client to hide all outgoing traffic via masquerading, making it appear as a single device. Next, create a second router or AP for your own private network, allowing devices to connect securely while remaining hidden from others. This arrangement may cause issues with certain online games because of double NAT, but placing your gaming PC in a DMZ should resolve the problem. Let me know if you need further guidance. I've added a basic diagram for clarity.
You're welcome! It matches what you expected. The diagram is very useful. Regarding your second question, using a tp-link RE500X AX1500 range extender with Ethernet out as a replacement for the first router connected to your landlord's AP is possible, but you should verify compatibility and ensure it meets your network needs.
It seems the router doesn’t come with built-in settings. Most home models support OpenWRT, allowing you to install it and access all desired features.
