Manufacturer description
The Cudy WE3000S brings Wi-Fi 6E and Bluetooth 5.3 to any desktop with a free PCIe x1 slot, and it does it on the Intel AX210 module rather than a no-name chipset. Tri-band AX5400 speeds break down as 2402 Mbps on 6GHz, 2402 Mbps on 5GHz, and 574 Mbps on 2.4GHz, so if your router already broadcasts a 6GHz SSID you get an uncrowded lane for low-latency gaming and interference-free 4K streaming. OFDMA, MU-MIMO, and 1024-QAM keep throughput efficient when a dozen other devices are fighting for airtime. The two detachable high-gain antennas mount on a magnetic base with a 1-meter cable, so you…
SpecPicks Verdict
SpecPicks scored Cudy Wi-Fi 6E Bluetooth 5.3 PCIe Adapter AX5400 with OFDMA using a rating × review-volume × price-fit model applied to published specs and reviews across the expansion cards category. Cudy's expansion cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for expansion cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Do I need a Wi-Fi 6E router to use this card?
No, but you need one to use the 6GHz band. Without a 6E router the card still connects at up to 2402 Mbps on 5GHz and 574 Mbps on 2.4GHz.
What chipset does the Cudy WE3000S use?
The Intel AX210 module, with a heatsink for thermal stability. It supports OFDMA, MU-MIMO, and 1024-QAM.
Will it fit my motherboard's PCIe slot?
It is a PCIe x1 card and works in x1, x4, x8, and x16 slots, so any open PCIe slot on a standard desktop board will take it.
How does the Bluetooth 5.3 connect?
Through an internal USB header cable that runs from the card to a USB header on your motherboard. The PCIe slot alone does not carry the Bluetooth signal.
Does it work on Linux?
Yes. Cudy lists support for Windows 10, Windows 11, and Linux. Check the product listing for current driver details for your distribution.
