UGREEN exact SKU 50922
Gigabit Ethernet through a USB-A 3.0 host port
A compact AX88179A-based adapter for wired networking, with an explicit distinction between its 5Gbps USB host link and 1Gbps Ethernet ceiling.
01 · Product introduction
Overview
UGREEN 50922 USB 3.0 to Gigabit Ethernet Adapter is a compact AX88179A-based adapter for wired networking, with an explicit distinction between its 5Gbps USB host link and 1Gbps Ethernet ceiling.
This exact-model guide separates link-rate ceilings from real throughput, explains what the entire cable or radio path must support, and states when operating-system or driver compatibility is conditional.
Research combines exact live UGREEN India product media with exact-model primary UGREEN material. Similar-looking adapters can use different chipsets, radios, speed ceilings and software.
Source reconciliation
Exact official product naming, gallery and controller evidence establish 10/100/1000Mbps Ethernet with AX88179A. An official Canada specification cell says '5Gbps data rate'; that is the USB 3.0 host signalling ceiling, not 5Gb Ethernet. Exact support lists native operation on Windows 11/10/8.1/8, macOS and ChromeOS, with a driver for Windows 7/XP/Vista and Linux. Nintendo Switch is supported; Wii, Wii U and Windows RT are excluded. No Wake-on-LAN, VLAN, PXE or jumbo-frame promise is included despite unrelated/regional references.

Link-rate ceilings and real throughput
The Ethernet link ceiling is 1Gbps. The 5Gbps number associated with USB 3.0 describes the host bus, not the RJ45 network rate.
Real Gigabit application throughput is lower than 1Gbps because of Ethernet, IP and transport overhead plus endpoint limitations.
A USB 2.0 port can operate the adapter in backward-compatible mode but can constrain real throughput below Gigabit.
The network link negotiates down to 100Mbps or 10Mbps if either endpoint or the cable route cannot establish Gigabit.
The adapter cannot exceed the broadband service, router/switch port, remote server or local storage speed.
05 · Complete path
What the host, cable or radio route must support
Use a USB-A 3.0 host port for sufficient upstream headroom; use USB 2.0 only with reduced expectations.
Use a four-pair Cat5e-or-better Ethernet cable and a Gigabit-capable network port.
Use a supported OS with native AX88179A operation or install the matching exact driver where required.
For Nintendo Switch, keep system software current and use a supported dock/USB connection mode.
Verify the negotiated Ethernet link independently from an internet speed test.
06 · Network behaviour
Standards, negotiation and operating roles
RJ45 link modes: 10Mbps, 100Mbps and 1Gbps auto-negotiation.
Exact controller: ASIX AX88179A.
USB 3.0 host signalling is up to 5Gbps theoretical; it is upstream headroom rather than a 5Gbps Ethernet claim.
The network interface normally receives IP, gateway and DNS details from the connected router or DHCP server.
The RJ45 socket provides data only: no IEEE PoE, passive power, modem or routing function.
Ceiling, not a promise
A port, radio or USB label is a signalling ceiling. Real performance depends on the complete path, protocol overhead, local conditions and the devices at both ends.

Setup and usability guidance
- Confirm SKU 50922 and check whether the target operating system needs the exact AX88179A driver.
- Connect the adapter directly to a USB-A 3.0 host port.
- Connect a Cat5e-or-better four-pair cable to a Gigabit-capable router, switch, modem or wall link.
- Wait for the Ethernet interface to appear and install the exact driver if required.
- Confirm the IP configuration and negotiated 1Gbps/100Mbps/10Mbps link in network settings.
- Use a local Gigabit endpoint to separate adapter performance from ISP and remote-server limits.
10 · Software
Driver and operating-system guidance
Exact sources list native operation on Windows 11/10/8.1/8, macOS and ChromeOS.
Windows 7, Windows XP, Windows Vista and Linux require a matching driver.
Linux success depends on kernel, distribution, CPU architecture and module-signing/Secure Boot policy.
Native-driver wording is not a promise that every future macOS, ChromeOS or managed-system release will remain unchanged.
Nintendo Switch compatibility depends on current system software and a supported USB connection.
Do not install software for a 2.5GbE or different-chipset adapter merely because the enclosure is similar.
Driver discipline
Match the exact SKU, chipset, operating-system version and CPU architecture. A driver for a similar enclosure can be incompatible with the hardware inside.
11 · Verified scope
What this product does
- Adds one auto-negotiating 10/100/1000Mbps RJ45 interface to a supported USB-A host.
- Uses a USB 3.0 host connection with enough theoretical headroom for Gigabit Ethernet.
- Uses the exact documented AX88179A controller and aluminium enclosure.
- Supports a current Nintendo Switch setup and listed computer operating systems within their driver rules.
12 · Clear boundaries
What this product does not do
- It does not provide 5Gb Ethernet; 5Gbps is the USB 3.0 host-bus label, while RJ45 stops at 1Gbps.
- It does not provide 2.5GbE, charging, USB pass-through or video output.
- It does not supply or receive PoE through RJ45.
- It does not support Wii, Wii U or Windows RT according to exact official material.
- It is not a modem, router, Wi-Fi adapter or Ethernet switch.

Product-specific FAQ
What exact model does this page cover?
This page covers UGREEN SKU 50922, the USB-A 3.0 Gigabit adapter using AX88179A.
What is the highest stated link speed?
RJ45 negotiates up to 1Gbps. The separate 5Gbps label is USB 3.0 host signalling, not 5Gb Ethernet.
Does it need a driver?
Modern Windows, macOS and ChromeOS are listed for native operation; legacy Windows and Linux require a matching driver.
Which hosts or network devices are compatible?
It supports listed USB computers and an updated Nintendo Switch setup; Wii, Wii U and Windows RT are excluded.
Will it make my internet faster?
No. It can provide a good wired client link but cannot exceed the service, network equipment or remote endpoint.
Does it support or supply PoE?
No. The RJ45 port neither provides nor receives PoE as an advertised function.
What do its USB or power connections actually do?
The USB-A plug carries host data and adapter power only; there is no charging, video or pass-through port.
What cable or radio path should I use?
Use a four-pair Cat5e-or-better Ethernet cable and USB 3.0 host port for Gigabit-class operation.
Is warmth normal?
Some warmth can be normal. Keep the body uncovered and stop if heat, odour or repeated resets are abnormal.
What should I check first if it does not work?
Check exact driver, USB 3.0 connection, cable pairs, Gigabit endpoints and the negotiated Ethernet rate.
What is included in the box?
The verified base package contains the UGREEN 50922 adapter and product documentation.
