USB Type-A to RJ-45 adapter VALUE 12.99.1119 — black, USB-A host, RJ-45 output, male-to-female, 22×59×16 mm

VALUE 12.99.1119 is a compact USB Type-A to RJ-45 adapter that adds a wired Ethernet interface to devices with a USB-A host port. The black, lightweight adapter (approximately 3 g) provides an RJ-45 network output and connects via a male USB-A plug. It supports USB 3.0 / USB 3.2 Gen 1 transfer modes and offers 10/100/1000 Mbit/s auto-sensing Ethernet performance for wired network access on systems without a built-in LAN port.

Advantages

This adapter delivers reliable wired connectivity in a small form factor, leveraging USB 3.0 bandwidth for improved network throughput compared with USB 2.0 solutions. It is bus-powered and requires no external power supply, making it convenient for travel and mobile use. The device is compatible with common desktop and laptop operating systems, enabling simple plug-and-play deployment when drivers are available.

Suitable for

• Adding wired Ethernet to laptops and desktops lacking a LAN port
• Establishing a stable network connection for streaming, downloads, or file transfers

How to use

Plug the USB-A male connector into an available USB-A host port on your computer or compatible device. Connect an Ethernet cable to the RJ-45 output. The adapter is bus-powered and will draw power from the host port. On supported operating systems (for example Windows 7, Windows 10 and Mac OS X 10.0 and later where drivers are available), the adapter will be detected and either install drivers automatically or prompt for driver installation. Once recognized, configure network settings via the operating system network control panel or use automatic DHCP if available.

Recommendations

For best network performance, use a USB 3.0-capable host port and a Gigabit-capable Ethernet cable and switch/router. Ensure drivers supplied by the operating system or the vendor are installed for full compatibility; for older systems check vendor driver support. Avoid excessive bending of the adapter and connected cable to preserve connector integrity.
