Understanding the Physical Topology
An unmanaged switch acts as a dumb bridge, forwarding data packets between connected devices based solely on MAC addresses. It does not perform routing, NAT, or IP address assignment. Therefore, the logical hierarchy of your network relies entirely on where the router is placed in this chain. The router serves as the gateway to the internet and the DHCP server that assigns IP addresses to your devices. If you connect the PCs directly to the switch without the router providing the upstream link, they will communicate with each other but have no access to external networks or online services like those required by the PlayStation TV. The specific instruction to use ports 3 and 4 for the Windows PCs is arbitrary from a technical standpoint, as all ports on an unmanaged switch are functionally identical. However, using distinct ports helps in cable management and troubleshooting. Port 1 is conventionally used for the uplink to the router because it separates the "upstream" traffic from the "downstream" device traffic. This separation makes it easier to identify which cables correspond to which devices if you need to replace a faulty cable later.Step-by-Step Connection Guide
Follow these steps to ensure your hardware is correctly linked before moving to software verification.- Connect the Router: Locate an Ethernet LAN port on your router (usually yellow or white, distinct from the blue WAN/Internet port). Connect one end of an Ethernet cable to this LAN port and the other end to port 1 on the unmanaged 24-port switch.
- Connect the First PC: Take a second Ethernet cable and connect one end to the Ethernet adapter of your first Windows 10 or 11 PC. Plug the other end into port 3 on the switch.
- Connect the Second PC: Use a third Ethernet cable to connect the second Windows PC to port 4 on the switch. Ensure the link lights on both the PC's network interface card (NIC) and the switch port illuminate, indicating a physical connection.
- Connect the PlayStation TV: Finally, connect the PlayStation TV to any remaining available port on the switch (e.g., port 5). Most modern consoles and streaming devices benefit from wired connections for stability, especially when accessing media libraries shared across the Windows PCs.
Verifying Network Configuration
After the hardware is connected, you must verify that the operating systems have obtained valid IP addresses. On Windows 10 and 11, open the Command Prompt by pressingWin + R, typing cmd, and hitting Enter. Type ipconfig and look for the IPv4 Address under your Ethernet adapter. It should typically be in the range of 192.168.1.x or 192.168.0.x, depending on your router's default settings. If you receive an APIPA address starting with 169.254.x.x, it means the PC failed to reach the router's DHCP server, indicating a broken cable or incorrect port usage.
If the IPs are correct, test connectivity by pinging the router's gateway address. For example, if your gateway is 192.168.1.1, type ping 192.168.1.1. A successful reply confirms that the path from the PC, through the switch, to the router is intact. You can also ping the PlayStation TV’s IP address to ensure inter-device communication works, which is crucial for features like Remote Play or media sharing.
For users looking to optimize their Windows experience beyond basic connectivity, understanding system permissions can be vital.

Troubleshooting Common Issues
If devices cannot see each other, check the Windows Firewall. Sometimes, the "Public" network profile blocks discovery. Go to Settings > Network & Internet > Ethernet and set the profile to "Private." This allows file and printer sharing to function correctly. Also, ensure that Media Streaming is enabled on the PlayStation TV via its settings menu, allowing it to recognize the Windows PCs as media sources.Frequently Asked Questions
Can I use a wireless adapter instead of Ethernet for the PCs?
Yes, but mixing wired and wireless connections on the same switch requires careful attention to IP subnets. Both the wired and wireless adapters must be on the same subnet assigned by the router to ensure seamless communication between the PCs and the PlayStation TV.
Does the number of ports on the switch matter for performance?
No, using only three ports out of twenty-four does not degrade performance. Unmanaged switches process traffic at line speed regardless of how many ports are active, provided the total bandwidth does not exceed the switch's backplane capacity, which is rarely an issue for standard home networking.
What happens if I swap port 1 with port 3?
The network will still function, but it breaks the logical convention of having the router as the primary uplink. While technically viable, this can cause confusion during troubleshooting, as you would need to remember that the internet source is plugged into a device port rather than the designated uplink port.
Will the PlayStation TV work if the Windows PCs are turned off?
Yes, the PlayStation TV connects directly to the router via the switch for internet access. However, features that rely on media servers running on the Windows PCs, such as DLNA streaming, will obviously fail if those PCs are powered down or disconnected from the network.
Is a managed switch necessary for this setup?
Not for basic connectivity. A managed switch offers VLANs and QoS, which are unnecessary for a simple home lab connecting two PCs and a console. An unmanaged switch is cost-effective and plug-and-play, making it ideal for this specific scenario.
