UGREEN exact SKU 75917
Tri-band Wi-Fi 6E for the exact Indian CM787 variant
A desktop AXE5400-class wireless adapter with two adjustable external antennas, a detachable USB data cable and explicit Windows-focused support.
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 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
UGREEN India live media and its exact page, plus UGREEN-applicant regulatory material, identify the Indian CM787/75917 as AXE5400 Wi-Fi 6E with 2.4/5/6GHz. A current UGREEN China support page reuses CM787/75917 for an AX3000 Wi-Fi 6 regional variant without 6GHz. The customer-facing copy therefore includes an explicit carton/label verification step. Exact India artwork states Windows 10/11 and says macOS/Linux are unsupported; 6GHz still requires Windows 11, a 6GHz router and local regulatory availability. No 6GHz Soft AP promise is made. The existing India text calls the detachable interface USB-C, while exact live gallery art calls the approximately 1m lead Micro USB; connector naming is therefore left neutral pending physical verification.

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.
05 · Complete path
What the host, cable or radio route must support
Before purchase, verify the exact 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 exact 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.
06 · Network behaviour
Standards, negotiation and operating roles
Indian exact-product class: Wi-Fi 6E / AXE5400 with 802.11ax operation across 2.4GHz, 5GHz and eligible 6GHz spectrum.
Backward network compatibility depends on the exact driver and access point; the higher Wi-Fi 6/6E features appear only when both ends support them.
Exact material lists WPA3-SAE security. Use WPA3 on 6GHz and prefer WPA3 or WPA2 on other bands according to router compatibility.
The exact 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.

Setup and usability guidance
- Check the carton and underside label for CM787 / 75917 and AXE5400 or Wi-Fi 6E before installing.
- Obtain the exact Indian driver/software package and follow its Windows installation instructions.
- Connect the supplied USB 3 host data cable directly between the computer and antenna base; do not substitute a charging-only lead.
- Place the base upright on an open surface, then adjust both antennas without forcing their hinges.
- In Windows Wi-Fi settings, select the intended SSID; use Windows 11 plus a compatible 6GHz network for Wi-Fi 6E.
- 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
Exact India media limits operating-system compatibility to Windows 10 and Windows 11.
The adapter requires its exact 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.
macOS and Linux are explicitly excluded by exact live artwork.
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 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 exact-variant tri-band Wi-Fi 6E networking to a supported Windows computer.
- Provides separate theoretical link ceilings up to 574Mbps, 2402Mbps and 2402Mbps across 2.4/5/6GHz.
- Uses a detachable USB 3 data cable and two positionable external antennas.
- Supports WPA3-SAE and Windows-dependent Soft AP functionality as listed for the exact Indian product.
12 · Clear boundaries
What this product does not do
- It does not deliver 5,400Mbps to one transfer or use all three band maxima simultaneously.
- It does not make Windows 10 a guaranteed 6GHz client platform.
- It does not have supported macOS or Linux operation in the exact Indian artwork.
- It is not an Ethernet adapter, stand-alone router, mesh extender or USB charging station.
- Its device-side USB data socket does not provide laptop charging, video or peripheral pass-through.

Product-specific FAQ
What exact model does this page cover?
This page covers the exact Indian CM787 / SKU 75917 AXE5400 Wi-Fi 6E variant; verify that wording on the carton because another region reuses the identifiers.
What is the highest stated link speed?
The separate ceilings are 574Mbps at 2.4GHz, 2402Mbps at 5GHz and 2402Mbps at 6GHz; one connection does not add them.
Does it need a driver?
Use the exact Windows software/driver. The page does not claim unconditional driver-free operation.
Which hosts or network devices are compatible?
Exact live art supports Windows 10/11; 6GHz requires Windows 11. macOS and Linux are listed as unsupported.
Will it make my internet faster?
No. It can improve the PC's radio link but cannot exceed the router, ISP plan, congestion or remote server.
Does it support or supply PoE?
No. It is a Wi-Fi adapter with no Ethernet or power-output role.
What do its USB or power connections actually do?
The base's detachable socket is for USB data and adapter power only; it does not charge a laptop, output video or host accessories.
What cable or radio path should I use?
Use the supplied USB 3 cable, place the antenna base in the open and use a Wi-Fi 6E router for 6GHz.
Is warmth normal?
Some warmth is possible during sustained traffic. Stop if heat, odour, resets or cable damage becomes abnormal.
What should I check first if it does not work?
Verify the physical AXE5400 label, correct Windows version, exact driver, USB 3 connection, band/security settings and router compatibility.
What is included in the box?
The verified configuration includes the antenna base, two attached antennas, an approximately 1m detachable USB host data cable and documentation; verify the device-side connector because exact India text and live art name it differently.
