A USB to Ethernet adapter turns a USB port into a wired RJ45 network connection. It creates a new network interface on your device so you can plug in an Ethernet cable and use a stable, wired connection.

• Setup: Plug the adapter into a USB-A or USB-C port, connect an Ethernet cable to your router or switch, then wait for your device to recognize it.
• Compatibility: Most modern laptops and desktops support plug‑and‑play; some older systems may prompt for a driver.
• Tips: Use a USB 3.x or USB‑C adapter for gigabit speeds, and optionally turn off Wi‑Fi to prioritize the wired link. Results can vary based on your device and network.

Wired connections can outperform Wi‑Fi when wireless signals are weak, congested, or obstructed by walls. A USB to Ethernet adapter may deliver more consistent speed and lower latency for streaming, calls, and gaming.

• Adapter and port: Gigabit (1000 Mbps) adapters paired with USB 3.x or USB‑C ports can handle high speeds.
• Plan and gear: Actual speed depends on your internet plan, router/switch ports, and cabling.
• 100 Mbps vs. gigabit: 100 Mbps adapters are fine for basic use; choose gigabit for faster plans or large file transfers.
• Expectations: Performance varies by environment. Even when top speeds match, wired often provides steadier performance than wireless.

Match the adapter to the port your device actually has, then consider speed and features.

• Port match: Use USB‑A adapters for standard rectangular USB ports; use USB‑C adapters for newer oval USB‑C ports.
• Speed: For gigabit Ethernet, pick USB 3.x or USB‑C. USB 2.0 models are typically limited to 10/100 Mbps.
• Extras: Hubs can add HDMI or additional USB ports; some offer pass‑through charging for compatible devices.
• Build and length: Look for a flexible cable or strain relief if you’ll move around.
• Compatibility: Check the product page for supported systems and any driver notes.

Many USB to Ethernet adapters work as plug‑and‑play on current operating systems, creating a network connection automatically. Some models or older systems may require a small driver.

• Quick start: Connect the adapter and Ethernet cable, then allow a minute for automatic setup.
• If prompted: Install the driver from the included guide or the manufacturer’s support page. Download ahead of time if you’ll be offline.
• Permissions: Managed work devices may need administrator approval to install drivers.
• Troubleshooting: Check your network settings and system updates if the adapter isn’t recognized. Product pages on Walmart.com list driver notes and compatible systems.

A few quick checks can help isolate the issue and get you online.

• Cables and lights: Reseat both ends of the Ethernet cable, try another cable, and look for link/activity LEDs on the adapter or router port.
• Ports and power: Try a different USB port. For best results, avoid unpowered hubs with gigabit adapters.
• Network settings: Ensure the wired adapter is enabled and set to automatic IP (DHCP). Temporarily turn off Wi‑Fi to prioritize wired.
• Drivers and updates: Install any required driver and reboot your device and router.
• Still stuck? Test on another device. If the issue persists, review the product’s Q&A and return policy on the Walmart product page.
