Which Plugable USB Network Adapter Is Right for My Computer?
The right Plugable adapter depends on your computer's USB port type (USB-A, USB-C, or Thunderbolt) and the network speed you need. Choose an adapter that fits your port and meets or exceeds your internet plan's speed or the speed of the other systems on your network.
How to Identify Your USB Port Type
Different Plugable adapters are designed for different USB connections. Here's how to tell which type of port your computer has:
- USB-A Port (Rectangular Shape) – Found on most older and some newer PCs and laptops. If your computer has standard USB ports, choose an adapter with a USB-A connector.
- USB-C Port (Small, Oval Shape) – Found on modern laptops, tablets, and some desktops. If your computer has a USB-C port, choose an adapter with a USB-C connector.
- Thunderbolt 3, 4, or 5 – Thunderbolt ports support USB-C accessories, so any Plugable USB-C Ethernet adapter will work.
Not sure which ports your computer has? Check the manufacturer's website or look for an icon next to the port. A lightning bolt indicates Thunderbolt (or charging), while a USB logo indicates the USB version.
How to Choose the Network Speed You Need
Your network speed depends on both your internet plan and the devices on your network. Choose an adapter based on the speed you want to achieve:
| Network Speed | Best Use Cases | Recommended Plugable Adapter |
|---|---|---|
| 100Mbps (Fast Ethernet) | Basic browsing, email, and light streaming | USB2-E100 (USB-A, 100Mbps) |
| 1Gbps (Gigabit Ethernet) | Streaming, gaming, and large file transfers |
USB3-E1000 (USB-A, 1Gbps) or USBC-E1000 (USB-C, 1Gbps) |
| 2.5Gbps and 5Gbps (Multi-Gig Ethernet) | High-speed networks, NAS, and 4K+ streaming |
USBC-E2500 (USB-C, 2.5Gbps) or USBC-E5000 (USB-C, 5Gbps) |
| Wi-Fi (802.11ax or Wi-Fi 6) | Adding Wi-Fi 6 to older notebook and desktop computers | USB-WIFINT (USB-A, Wi-Fi 6, 350Mbps) |
For the best results, match or exceed your internet provider's rated speed, or for local file transfers, the speed of the other systems on your network. For example, with a 2Gbps internet plan, a 2.5Gbps or 5Gbps adapter is a good fit. A 1Gbps adapter will still connect, but it will be limited to about half of the plan's rated speed.
Before choosing a multi-gig adapter, check your router's specifications to confirm it supports speeds of 2.5Gbps or higher.
How to Choose the Right Adapter for Your Computer
For USB-A Computers
- Need basic 100Mbps Ethernet? Choose the USB2-E100.
- Need Gigabit speeds? Choose the USB3-E1000.
- Need wireless connectivity? Choose the USB-WIFINT.
For USB-C or Thunderbolt 3/4 Computers
- Need Gigabit speeds? Choose the USBC-E1000.
- Need 2.5Gbps speeds? Choose the USBC-E2500.
- Need 5Gbps speeds? Choose the USBC-E5000.
Compatibility Considerations
- USB 3.0 adapters in USB 2.0 ports: These will work, but they will be limited to USB 2.0 speeds, which may reduce network performance.
- Operating system support: Most Plugable network adapters work with Windows, macOS, and Linux. The USB-WIFINT relies on proprietary drivers and is not recommended for macOS, Linux, or ChromeOS.
- Faster adapters and internet speed: A faster adapter only increases internet speed if your internet plan supports it. A 2.5Gbps adapter will not improve speeds on a 1Gbps internet connection.
- USB-C adapters on USB-A computers: Some USB-C to USB-A adapters may work, but many are limited to USB 2.0 data rates and can reduce network performance. For the most reliable performance, use a native USB-A Ethernet adapter.
