## Summary description

Wired USB-C to Gigabit Ethernet adapter StarTech US1GC30B2 provides a USB 3.0 host interface to connect devices to 10/100/1000 Mbps networks via an RJ45 port. The compact adapter includes a fixed 12in cable, offers up to 5000 Mbit/s maximum transfer rate as specified, and supports driverless installation for plug-and-play use. Ideal for laptops, tablets, and ultrabooks lacking an onboard Ethernet port and for stable wired network access in offices, home networks, and travel.

## Long description

The StarTech USB-C to Gigabit Ethernet Adapter US1GC30B2 provides a simple wired network connection for computers and mobile devices with a USB Type-C port. The compact dongle integrates a fixed 12 in (30 cm) cable and an RJ45 port that supports 10/100/1000 Mbps networks, enabling reliable wired access where Wi-Fi is unavailable or inconsistent. The adapter supports native, driverless installation across major desktop and mobile platforms for quick plug-and-play setup and includes features such as VLAN tagging, Auto-MDIX, 9K jumbo frames, wake-on-LAN and full-duplex Ethernet for improved network functionality.
Advantages
This USB-C to RJ45 adapter delivers Gigabit-class performance with compatibility for Cat5 and higher cabling while remaining lightweight and portable. Native driver support on Windows, macOS and Linux plus compatibility with ChromeOS, Android and iPadOS reduces setup time and eliminates the need to manually install drivers in most environments. The built-in 12 in cable provides additional reach and reduces strain on device ports, and USB bus power makes the adapter convenient for travel and temporary network use.
Suitable for
 Laptops and ultrabooks without a built-in Ethernet port
 Tablets and mobile devices with USB-C that require a wired connection
 Office workstations needing stable network access for file sharing or backups
 Home networks and streaming where Wi-Fi is unreliable
 Travel and temporary workstations in hotels or conference venues

How to use
Connect the adapter's USB-C plug to a computer or mobile device equipped with a compatible USB Type-C port. Attach an Ethernet cable from your network to the RJ45 port on the adapter. Most modern operating systems will recognize the adapter automatically and configure network settings for immediate use. If necessary, verify that the device's network preferences are set to use the wired connection and consult the system network settings to prioritize Ethernet over Wi‑Fi.
Usage recommendations
For stable Gigabit performance, use Cat5e or higher cabling and connect to Gigabit-capable network equipment. Avoid sharp bends in the fixed cable and allow slight slack to minimize strain on the device port. When moving between networks or devices, confirm network profiles and security settings; use the StarTech.com Connectivity Tools application if advanced link management, MAC pass-through or USB event monitoring is required.
