Realtek RTL8156 is a network adapter that supports 2.5 Gigabit Ethernet (2.5 GbE) speeds.
The Realtek RTL8156 is designed to provide faster network connectivity compared to traditional Gigabit Ethernet (1 GbE) adapters. With its 2.5 GbE capability, it offers higher data transfer rates, making it suitable for tasks that require increased network bandwidth, such as transferring large files, streaming high-definition media, and online gaming.
The adapter typically utilizes a USB 3.2 Gen 1 interface to deliver the higher network speeds. It is backward compatible with slower Ethernet standards, allowing it to work with existing 1 GbE and 100 Mbps networks.
