Pros & Cons
Pros
- ✓ USB 3.0 interface avoids the USB 2.0 bottleneck that caps older AC dongles
- ✓ 867Mbps on 5GHz, 400Mbps on 2.4GHz, band selectable per situation
- ✓ Mini form factor does not overhang and block the adjacent USB port
- ✓ Native driver support spans Windows 11/10/8.1/8/7 and macOS
Cons
- ✗ Internal antenna trades range for size versus an external-antenna adapter
- ✗ WPA2 only, no WPA3 support listed
- ✗ 802.11ac, so no WiFi 6 or 6E gains on a newer router
- ✗ Single-band operation at a time, not simultaneous dual band
Manufacturer description
The Cudy WU1300S is a mini USB 3.0 WiFi adapter that gives an aging laptop or desktop modern 802.11ac dual-band wireless without opening the case. It delivers up to 867Mbps on the 5GHz band for streaming and large file transfers, and 400Mbps on 2.4GHz when you need range through walls, and you pick the band that suits the room. The USB 3.0 interface is the piece that matters here: it keeps the adapter from bottlenecking the way older USB 2.0 dongles do at AC speeds. Cudy keeps the footprint small enough that it will not block the USB port next to it, and the antenna is internal, so nothing…
SpecPicks Verdict
SpecPicks scored Cudy AC1300 Dual Band USB 3.0 Mini WiFi Adapter PC Mac Dongle WU1300S using a rating × review-volume × price-fit model applied to published specs and reviews across the retro networking cards category. Cudy's retro networking 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 retro networking 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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Will this work on Windows 11?
Yes. Cudy lists native support for Windows 11, 10, 8.1, 8, and 7, plus macOS. You install the bundled driver, then select your network.
Do I need a USB 3.0 port to use it?
The adapter uses a USB 3.0 interface to reach its full 867Mbps 5GHz rate. USB ports are backward compatible, but a USB 2.0 port will limit throughput.
Can it connect to 5GHz and 2.4GHz at the same time?
No. It is a selectable dual-band adapter: you choose either the 867Mbps 5GHz band or the 400Mbps 2.4GHz band for each connection.
Does it support WPA3 security?
The listed encryption is WPA2. If your router is set to WPA3-only, switch it to WPA2/WPA3 mixed mode or check the current listing for updated driver support.
