ICY BOX IB-AC501a — Gigabit Ethernet from a USB 3.0 port
USB 3.0 Type-A1x RJ45 GigabitJumbo framesBlack
The ICY BOX IB-AC501a by RaidSonic is a USB 3.0 to Gigabit Ethernet adapter that adds a 10/100/1000 Mbps RJ45 port to laptops and desktops through a USB Type-A port. It is meant for notebooks without a network socket, desktops with a defective onboard LAN, and users who want a more stable connection than Wi-Fi.
RaidSonic specifies IEEE 802.3, 802.3u and 802.3ab compliance, full and half duplex, jumbo frame support and reduced EMI radiation. A LAN activity LED shows when data is flowing, and the adapter connects through a short cable so it does not put leverage on the USB port. The black plastic housing weighs only 19 g.
The adapter is backward compatible with USB 2.0 and 1.x ports, though full Gigabit throughput needs USB 3.0. A CD with manual and driver is included.
Before you order: RaidSonic does not publish an operating system list for this adapter, and the driver is supplied on CD. If your computer has no optical drive or you run macOS or Linux, send us the details and we will confirm before you order.

Singular Expert Insight · Buyer's Guide
The IB-AC501a is a compact USB-A Gigabit adapter with jumbo frame support. Because no OS list is published, it suits Windows desktops best; for Mac or Linux, other
network adapters in our range list those systems explicitly.
✓ Buy it if you need a small USB-A Gigabit adapter for a Windows laptop or desktop.
✕ Skip it if you need a published macOS/Linux compatibility list, a USB-C plug, or 2.5G.
→ Also consider i-tec U3METALGLAN (Windows/macOS/Linux listed) or TRENDnet TU3-ETG.
Send us your laptop model and operating system and we will confirm compatibility before you order.
