UGREEN exact SKU 20264
Fast Ethernet and three USB 2.0 data ports from one USB-A host
A four-function USB 2.0 adapter built around the documented AX88772 network controller, with honest 100Mbps Ethernet and shared bus-power limits.
01 · Product introduction
Overview
UGREEN 20264 USB 2.0 Ethernet Adapter with 3-Port USB Hub is a four-function USB 2.0 adapter built around the documented AX88772 network controller, with honest 100Mbps Ethernet and shared bus-power limits.
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 sources establish USB 2.0, three USB-A data ports, 10/100Mbps RJ45, AX88772, optional 5V auxiliary input and a 5V/500mA combined bus-powered USB ceiling. The listed integrated lead length conflicts at roughly 20cm versus 28cm by region/batch, so no single exact length is promised. India lists Windows 8/7/Vista/XP, macOS 10.11+ and Linux 2.6/3.x, but present systems may require a matching driver. The power adapter is not included. This is not Gigabit, a charging hub, PoE or a stand-alone switch.

Link-rate ceilings and real throughput
The Ethernet link ceiling is 100Mbps, not 1Gbps. Real TCP/IP throughput is lower because of protocol overhead.
The three USB ports share one USB 2.0 host path with a theoretical 480Mbps signalling ceiling and cannot each deliver 480Mbps simultaneously.
When bus-powered, the documented combined USB output ceiling is 5V/500mA. High-draw hard drives, optical drives or several devices can exceed that budget.
The optional 5V input can improve peripheral power stability but does not change the Ethernet link above 100Mbps or turn the ports into a charger.
Internet speed remains limited by the 100Mbps Ethernet link, router, ISP and remote service.
05 · Complete path
What the host, cable or radio route must support
Use a computer or console USB-A port that supports USB host data; a power-only socket cannot operate the hub.
Use a Cat5e-or-better Ethernet cable for a reliable 100Mbps link and connect it to a router, switch, modem or wall network.
Install the matching AX88772 driver when the operating system does not provide one.
Keep the combined current of bus-powered USB peripherals within the host/hub limit or use the optional correct 5V auxiliary input.
Externally power demanding drives themselves when possible; the hub's auxiliary input is not evidence that every high-current device is supported.
06 · Network behaviour
Standards, negotiation and operating roles
Network controller: ASIX AX88772 with IEEE 802.3 / 802.3u 10/100 Ethernet operation.
RJ45 supports full- or half-duplex according to negotiation with the connected network device.
USB ports are USB 2.0 data ports with a shared theoretical 480Mbps bus.
The adapter creates a network interface and a three-port USB hub; the router still provides DHCP, gateway and internet service.
No Gigabit Ethernet, USB charging protocol, PoE, USB video or stand-alone switching function is claimed.
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 20264 and obtain the matching AX88772 driver before disconnecting an existing network when the OS may need it.
- Connect the USB-A host plug directly to a data-capable computer or supported console port.
- Connect Ethernet to the RJ45 socket and wait for the link indicator.
- Add low-power USB devices one at a time while watching for resets or disconnections.
- If the peripheral load exceeds stable bus power, use only a correctly rated 5V auxiliary supply or separately powered peripherals; no adapter is included.
- Verify the 10/100 negotiated Ethernet link and shared USB behaviour before relying on the setup.
10 · Software
Driver and operating-system guidance
Exact India material lists older Windows releases, macOS 10.11+ and historical Linux kernel families, reflecting the product's age.
Modern Windows, macOS and Linux releases may or may not include a suitable AX88772 driver; verify the exact OS and architecture.
The included driver CD is useful only on a compatible optical drive and may contain older software; prefer a current trusted exact driver when available.
Apple-silicon Mac compatibility is not established by an older macOS 10.11+ statement.
Console compatibility depends on current system software and supported USB networking mode.
The USB hub function and network function share one host connection; driver or power failure can affect both.
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 10/100Mbps RJ45 network interface and three USB 2.0 data ports to a compatible USB-A host.
- Uses the exact documented AX88772 network controller.
- Can accept optional 5V auxiliary input to support the hub's peripheral power budget.
- Supports useful low-power peripherals such as keyboard, mouse, receiver and flash drive within the shared limits.
12 · Clear boundaries
What this product does not do
- It does not provide Gigabit Ethernet; the RJ45 ceiling is 100Mbps.
- It does not give each USB port an independent 480Mbps path.
- It is not a charging hub and does not support USB-C PD or fast-charge protocols.
- It does not include the optional 5V power adapter.
- It does not provide PoE, video output, a router or a stand-alone Ethernet switch.

Product-specific FAQ
What exact model does this page cover?
This page covers UGREEN SKU 20264, the AX88772-based 10/100 Ethernet adapter with three USB 2.0 data ports.
What is the highest stated link speed?
Ethernet negotiates up to 100Mbps, not Gigabit. The three USB ports share one 480Mbps-theoretical USB 2.0 bus.
Does it need a driver?
Driver needs depend on the exact OS. Historical India material lists older Windows, macOS 10.11+ and Linux 2.6/3.x.
Which hosts or network devices are compatible?
It suits compatible USB-A computers and listed consoles, plus low-power USB peripherals within the shared current budget.
Will it make my internet faster?
No. The Ethernet port itself caps the wired link at 100Mbps and the router, ISP and server can impose lower limits.
Does it support or supply PoE?
No. It provides Ethernet data only and cannot power a PoE device.
What do its USB or power connections actually do?
The optional 5V socket supplements hub power; it does not charge a laptop or turn the USB ports into fast-charging outputs.
What cable or radio path should I use?
Use a sound Ethernet cable and remember the integrated host lead varies by regional batch at roughly 20–28cm.
Is warmth normal?
Some warmth is possible. Stop if heat, odour or resets are abnormal, especially when several peripherals are attached.
What should I check first if it does not work?
Remove USB peripherals, install the exact driver, verify Ethernet separately, then add low-power devices one at a time.
What is included in the box?
The exact India listing includes the adapter/hub, driver CD and documentation; the optional 5V power adapter is not included.
