Ethernet adapter Dell USB-C to RJ-45 0D59GG Gigabit Ethernet, USB-C to 1x RJ-45

The Dell USB-C to RJ-45 Gigabit Ethernet adapter provides a straightforward wired network connection for laptops and devices with a USB-C port but without a built‑in Ethernet jack. The compact adapter converts a single USB-C interface to a standard RJ-45 port, allowing access to wired networks for stable, low-latency connectivity suitable for business and home use.

Advantages

This adapter delivers Gigabit Ethernet performance over a USB‑C connection, offering lower latency and more consistent throughput than typical wireless links. Its plug-and-play design requires no external power and supports compact portability. The single RJ-45 port ensures compatibility with standard network cabling and managed switches, while the rugged connector and molded cable provide reliable daily use.

Suitable for

• Video conferencing and VoIP with stable wired connection
• Large file transfers and backups over Gigabit networks
• Corporate environments requiring reliable network access
• Home offices or remote work setups where Wi‑Fi is unstable
• Devices without integrated Ethernet ports such as ultrabooks and tablets

Key specifications

• Interface: USB-C host connector to one RJ-45 network port
• Network speed: Supports Gigabit Ethernet (up to 1000 Mbps)
• Compatibility: Works with devices that support USB-C data connections
• Power: Bus-powered via USB-C (no external power supply required)
• Physical: Compact form factor with short attached cable for portability

How to use

Connect the adapter's USB-C plug to a compatible USB-C port on the laptop or device. Plug a standard Ethernet cable into the RJ-45 port and connect the other end to a network outlet, switch, or router. Most operating systems will detect the adapter automatically and configure network settings via DHCP; if necessary, select the wired network in system network settings or install vendor-supplied drivers when prompted.

Recommendations

For optimal performance, use Category 5e or higher Ethernet cabling and connect to Gigabit-capable network equipment. Avoid excessive bending of the short cable and keep the connector area free from dust and moisture. When using in managed networks, verify VLAN or security settings with your network administrator if the device does not obtain an IP address automatically.
