FAQs
What is the difference between this adapter and a standard Gigabit Ethernet adapter?
The Simplecom NU405C delivers 2.5Gbps speeds versus 1Gbps from standard Gigabit adapters—2.5x faster. It complies with IEEE 802.3bz (2.5GBASE-T) standard and is ideal for modern networks and high-bandwidth applications like 4K file transfers.
Will this adapter work with older Ethernet networks?
Yes. The NU405C is backward compatible with 100Mbps and 1Gbps networks. It automatically negotiates the appropriate speed for your network, so it works seamlessly with existing infrastructure.
Do I need to install drivers?
The NU405C is plug-and-play on Windows 7+, macOS 10.10+, and ChromeOS. Most systems recognise it immediately; however, check the manufacturer's website for the latest drivers if needed.
Does this adapter require external power?
No. The NU405C is fully bus-powered through the USB port, so it draws power directly from your device without needing a separate power adapter.
Can I use both USB-C and USB-A connectors at the same time?
No. The NU405C features hybrid USB-C and USB-A connectors, meaning you use one or the other depending on your device's port type—not both simultaneously.
Is this suitable for gaming or streaming applications?
The 2.5Gbps speed is suitable for most applications including streaming and casual gaming. For competitive esports or high-frequency trading, dedicated network optimisation may be preferred.
What is the cable length?
The integrated cable is 10cm long, providing a compact form factor ideal for portable and desk-bound setups.
