I just set up a TP-Link LS1005G switch. It’s one of the most affordable and straightforward options I discovered from a trustworthy seller—perfect for my needs. It features five gigabit Ethernet ports, each with an LED next to it. One port links to my always-on home router, while the others connect to my computer and a Raspberry Pi. Following the manual, a steady LED means a connection is active, and a flashing one suggests data transfer is happening. However, in the evening, often none of the devices are powered up—still, a connected port must light up. The odd occurrence is seeing the router’s LED blink on by itself when others are off. Why? It seems unlikely any data is moving unless the ports are active.

They tend to stay active all the time. When a connection exists, the two NICs exchange keep-alive messages to confirm they are functioning properly.

Transmissions or group/IGMP data from the router may reach the switch.
