Manufacturer description

The Plugable 2.5G USB-C and USB to Ethernet Adapter solves a specific problem: your laptop has fast Wi-Fi but no wired port, and your router already supports 2.5Gbps. This dual-connector adapter converts between USB-C and USB-A without a dongle chain, so it moves between a Thunderbolt 5 MacBook, a USB 3.0 desktop, a Chromebook, and an iPhone 15 or 16 running iOS 17+ without you buying a second adapter. Plugable rates it at double the throughput of a standard Gigabit adapter when paired with 2.5Gbps-capable switches or routers, and it runs that speed over the Cat 5e cabling already in your…

Frequently Asked Questions

Will this actually give me 2.5Gbps speeds?

Only if the rest of your chain supports it. Plugable notes the adapter reaches 2.5Gbps when paired with a 2.5Gbps-capable switch or router and connected to a USB 3.0 or faster port. On Gigabit gear it falls back to Gigabit speeds.

Do I need to replace my Ethernet cables?

No. Plugable states 2.5 Gigabit signals are designed to run on Cat 5e cabling or better, so existing runs generally work without rewiring.

Does it work with both USB-C and USB-A ports?

Yes. It is a hybrid 2-in-1 design that converts between USB-C and USB-A, and Plugable lists compatibility with Thunderbolt 5 and 4, USB4, and USB 3.0 hosts. USB 3.0 or better is required for full performance.

Do I have to install drivers?

Plugable describes it as true plug-and-play across Windows, macOS, ChromeOS, and iOS. For a specific OS build, check the current listing or Plugable support before purchase.

Can I use this with my iPhone?

Plugable lists support for iPhone 15 and 16, including Pro and Pro Max, on iOS 17 or later. Older iPhone models are not listed as supported.
