What it does well.
Key features
02 · At a glance
10/100Mbps Ethernet. The Ethernet link ceiling is 100Mbps, not 1Gbps. Real TCP/IP throughput is lower because of protocol overhead.
3 × USB 2.0 data. Use a computer or console USB-A port that supports USB host data; a power-only socket cannot operate the hub.
AX88772. Network controller: ASIX AX88772 with IEEE 802.3 / 802.3u 10/100 Ethernet operation.
Optional 5V input. India material lists older Windows releases, macOS 10.11+ and historical Linux kernel families, reflecting the product's age.
Every interface and indicator explained
03 · Connector clarity
USB-A 2.0 host plug. Connects the combined hub/network adapter to a computer or compatible console USB host.
3 × USB-A 2.0 data ports. Share the host's 480Mbps theoretical USB bus and available current; intended for peripherals and moderate-speed storage, not modern high-speed SSD performance.
RJ45 10/100 socket. Auto-negotiates 10Mbps or 100Mbps Ethernet through the AX88772 controller; there is no Gigabit mode.
Optional DC 5V input. Can supplement accessory power when a correct external 5V supply is used. The power adapter is not included and the socket is not a charging output.
Link/activity indicators. Report Ethernet link and traffic state; they do not show throughput or internet availability.
Link-rate ceilings and real throughput
04 · Performance planning
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.
What the host, cable or radio route must support
05 · Complete path
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.
Standards, negotiation and operating roles
06 · Network behaviour
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.
Compatible devices and systems
07 · Device fit
Windows legacy systems. India material lists Windows 8/7/Vista/XP. These releases may require the included/downloaded driver and have significant security limitations.
macOS 10.11 and later in listed material. Use only where a matching AX88772 driver exists for the macOS release and CPU architecture.
Linux 2.6 / 3.x in listed material. Those are historical kernel references; current Linux support depends on the active kernel driver and architecture.
Nintendo Switch / Wii examples. Official regional material lists console use, but current system software, USB mode and the console's own network ceiling apply.
USB keyboards, mice, receivers and flash drives. Good low-power data-hub uses within the shared USB 2.0 bandwidth and current budget.
Use scenarios
08 · Practical value
Legacy laptop port expansion. Add 100Mbps Ethernet plus keyboard, mouse and a low-power USB accessory through one USB-A port.
Console wired networking. Use a supported console USB host with the correct system software and Ethernet connection.
Bench or service adapter. Connect modest-speed USB peripherals while adding a temporary Fast Ethernet interface.
Travel with low-power accessories. Combine wired network, receiver and flash-drive connectivity without claiming modern high-speed hub performance.
Setup and usability guidance
09 · Usability
- 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.
Driver and operating-system guidance
10 · Software
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 OS and architecture.
The included driver CD is useful only on a compatible optical drive and may contain older software; prefer a current trusted 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 this SKU, chipset, operating-system version and CPU architecture. A driver for a similar enclosure can be incompatible with the hardware inside.

Avoid. Do not advertise this 100Mbps adapter as Gigabit.
Avoid. Do not connect a random power adapter to the auxiliary input.
Avoid. Do not use the hub as a stand-alone phone charger.
Avoid. Do not attach several high-draw hard drives and assume bus power is sufficient.
Avoid. Do not remove a storage device while data is being written.
Warnings and limitations
15 · Read before use
Warning / limitation 1. Wrong auxiliary-supply voltage or polarity can damage the hub, host or peripherals; use only a compatible 5V supply.
Warning / limitation 2. The combined 5V/500mA bus-powered figure is a ceiling, not a guaranteed allocation to every port.
Warning / limitation 3. Legacy operating systems listed by historical material may no longer receive security updates.
Warning / limitation 4. Safely eject storage before disconnecting the hub to avoid filesystem corruption.
Warning / limitation 5. Stop use if the cable, DC socket or USB connector is damaged or if heat/odour becomes abnormal.
Troubleshooting by symptom
16 · Diagnostics
Network interface is missing. Install the AX88772 driver, reconnect directly to the host and test without USB peripherals.
USB devices disconnect. Reduce the combined peripheral load, avoid high-draw drives or use a compatible 5V auxiliary supply.
Ethernet stops near 100Mbps. That is the model's link ceiling; it is not a Gigabit adapter.
Hub works but internet does not. Check Ethernet link, DHCP, gateway, router uplink and ISP status separately.
Console does not recognise it. Update console software, verify its supported USB network mode and test the adapter on a listed computer.
