The short version
Plugable's USBC-E2500 adds 2.5 gigabit Ethernet to a laptop or desktop through USB-C, or USB-A via its attached adapter, using a Realtek RTL8156 chipset. It auto-negotiates 100 Mbps, 1 Gbps and 2.5 Gbps and supports 9K jumbo frames and VLAN tagging. It suits multi-gig home networks and NAS users. Full speed requires a USB 3.0 or faster port, and Plugable notes older operating systems may need a driver download.

Common questions
Will it reach 2.5 Gbps on a USB-A port?
Yes, if the port is USB 3.0 or faster. Plugable says USB 3.0 is required for full performance, and the attached adapter converts between USB-C and USB-A.
Does it need a driver?
Plugable says most modern operating systems work plug-and-play, though older systems or kernels may need a driver download.
