01 · Product introduction

Overview

UGREEN 75917 AXE5400 Tri-Band Wi-Fi 6E USB Adapter (CM787) is a desktop AXE5400-class wireless adapter with two adjustable external antennas, a detachable USB data cable and explicit Windows-focused support.

This 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.

02 · At a glance

Key features

01

2.4 + 5 + 6GHz

AXE5400 is a rounded class label combining separate theoretical ceilings: up to 574Mbps at 2.4GHz, 2402Mbps at 5GHz and 2402Mbps at 6GHz. One client connection does not add all three bands together.

02

574 + 2402 + 2402Mbps

Before purchase, verify the Indian carton and product label show CM787 / 75917 and AXE5400 or Wi-Fi 6E, because another current regional product reuses the identifiers for AX3000.

03

Wi-Fi 6E

Indian product class: Wi-Fi 6E / AXE5400 with 802.11ax operation across 2.4GHz, 5GHz and eligible 6GHz spectrum.

04

WPA3-SAE

India media limits operating-system compatibility to Windows 10 and Windows 11.

03 · Connector clarity

Every interface and indicator explained

01

Detachable device-side USB data socket

02

Supplied USB host data cable

03

2 × adjustable external antennas

Angle the antennas for stable reception and keep them clear of metal obstructions; the design is high-gain but cannot overcome every wall or interference source.

04

Status indicator

Shows adapter/connection activity according to the installed software; it is not an signal or speed meter.

05

No RJ45 socket

This is a wireless adapter, not an Ethernet adapter or router.

The external antennas can be positioned for the room, but walls and local interference still determine real coverage.

04 · Performance planning

Link-rate ceilings and real throughput

AXE5400 is a rounded class label combining separate theoretical ceilings: up to 574Mbps at 2.4GHz, 2402Mbps at 5GHz and 2402Mbps at 6GHz. One client connection does not add all three bands together.

6GHz can provide cleaner spectrum and more wide-channel opportunities at short range, but it generally penetrates walls less effectively and requires a Wi-Fi 6E access point.

Real throughput is lower than the negotiated wireless rate because of protocol overhead, shared airtime, channel width, interference, distance, router capability and the remote service.

The supplied USB 3 path is necessary to avoid a USB 2.0 bottleneck at the higher wireless link classes.

The adapter can improve the computer's radio link; it cannot increase the broadband plan, router backhaul or remote server speed.

AXE5400 is the rounded class sum of three separate band ceilings; a client does not combine them into one transfer.

05 · Complete path

What the host, cable or radio route must support

Before purchase, verify the Indian carton and product label show CM787 / 75917 and AXE5400 or Wi-Fi 6E, because another current regional product reuses the identifiers for AX3000.

Use Windows 11, a Wi-Fi 6E router/access point and a country configuration that permits 6GHz to use the 6GHz band.

Windows 10 is listed for the adapter, but do not assume that means 6GHz operation; use the documented 2.4GHz/5GHz paths and current driver.

Install the software/driver package before expecting the adapter to appear, especially when the installer is presented through onboard or bundled storage.

Place the antenna base on an open desk using the supplied data cable rather than trapping it behind a metal PC enclosure.

6GHz and 160MHz operation require Windows 11, compatible access-point settings and locally permitted spectrum.

06 · Network behaviour

Standards, negotiation and operating roles

Indian product class: Wi-Fi 6E / AXE5400 with 802.11ax operation across 2.4GHz, 5GHz and eligible 6GHz spectrum.

Backward network compatibility depends on the driver and access point; the higher Wi-Fi 6/6E features appear only when both ends support them.

Material lists WPA3-SAE security. Use WPA3 on 6GHz and prefer WPA3 or WPA2 on other bands according to router compatibility.

The India product title lists Soft AP mode. Treat availability as driver/Windows dependent and do not promise a 6GHz hotspot.

The adapter is a client radio interface, not a wireless router, mesh node or stand-alone range extender.

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.

Congested office or apartment radio space

Use 5GHz or eligible 6GHz when a compatible router offers a cleaner channel than 2.4GHz.

04

Windows 10 dual-band upgrade

Use supported 2.4GHz/5GHz operation without representing Windows 10 as a guaranteed 6GHz platform.

09 · Usability

Setup and usability guidance

  1. Check the carton and underside label for CM787 / 75917 and AXE5400 or Wi-Fi 6E before installing.
  2. Obtain the Indian driver/software package and follow its Windows installation instructions.
  3. Connect the supplied USB 3 host data cable directly between the computer and antenna base; do not substitute a charging-only lead.
  4. Place the base upright on an open surface, then adjust both antennas without forcing their hinges.
  5. In Windows Wi-Fi settings, select the intended SSID; use Windows 11 plus a compatible 6GHz network for Wi-Fi 6E.
  6. Confirm WPA3/WPA2 settings, obtain an IP address and test near the router before evaluating the final desk position.

10 · Software

Driver and operating-system guidance

India media limits operating-system compatibility to Windows 10 and Windows 11.

The adapter requires its driver/software environment; do not advertise unconditional driver-free operation.

6GHz Wi-Fi 6E client operation requires Windows 11 support in addition to a compatible access point and permitted regional spectrum.

Windows 10 listing does not establish 6GHz support; describe it as supported adapter operation on compatible 2.4GHz/5GHz networks.

Do not use the current China CM787/75917 AX3000 package or driver description as proof that the Indian AXE5400 radio has identical regional firmware.

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.

15 · Read before use

Warnings and limitations

01

Warning / limitation 1

6GHz availability depends on national regulation, Windows 11, access-point support and the network configuration.

02

Warning / limitation 2

Wireless performance varies with distance, building materials, interference, channel width and router design.

03

Warning / limitation 3

A Soft AP shares the computer's network and can create a security exposure; use a strong password and follow workplace policy.

04

Warning / limitation 4

Stop use if the cable, connector or antenna hinge is damaged or the enclosure becomes abnormally hot.

05

Warning / limitation 5

Regional identifier reuse is a purchasing risk: verify the physical AXE5400/Wi-Fi 6E label before relying on tri-band claims.

16 · Diagnostics

Troubleshooting by symptom

01

6GHz SSID is missing

Verify Windows 11, Wi-Fi 6E router mode, permitted regional settings, current driver and adequate proximity to the access point.

02

Adapter is not detected

Reconnect the supplied USB 3 cable, try a direct USB-A port and install the Indian CM787 software.

03

Connection falls back to 5GHz or 2.4GHz

Check signal, router band steering, 6GHz security and OS support; band choice is negotiated, not forced by the AXE5400 label.

04

Speed is below the link class

Separate PHY rate from application throughput, then verify USB 3, channel width, router capability, distance and service limits.

05

Software identifies AX3000 instead of AXE5400

Stop and verify the physical carton, label, regional hardware and downloaded package before applying any firmware or driver.
