UGREEN Wifi Dongle, AX900 WiFi 6 Adapter Dual Band 5GHz/2.4GHz for PC

I paid £7.96 for this USB Wifi Dongle on sale and for the price this is top tier value. On Windows 11 initially it will show up as a tiny usb storage device with the driver included, a double click and it installs in just a few moments, and now gets correctly recognised as a WiFi device on that specific PC. Internet speeds average ~260 Mbps. which is close the boxs claimed 2.4ghz max transfer rate of 286 Mbps. However gaming is less about pure speed and more about network latency and im happy to report that ping is speedy and reliable. It's perfectly fine for casual online gaming in my time testing it. Linux A welcome surprise, despite this listing advertising no Linux compatibility, the product box itself says it supports "Linux kernel 3.10~6.8". Granted it doesnt work immediately and you will need to manually download and install a driver but I didnt find it too much of a hassle and its infinitely better then zero Linux support. I managed to get it working on linux distros like Debian 13 and Ubuntu 24.04.4, both on real hardware and inside a virtual machine. Ironically, I can't get the official linux drivers from UGREEN download centre to work, tried both the driver package and manually compiling, but thankfully there is a tenda driver for a different WiFi dongle also works with this one due to both sharing the same WiFi chipset. It works for debian based Linux distributions. There is also a community github driver you can try for non debian based Linux distributions but I havent tested it yet. I can't post the links here but it should be one of the first results when searching "reddit UGREEN AX900 driver" in r/linuxmint So yeah, the painless windows setup, fast and consistent speed and ping, plus linux compatibility makes for a versatile product that well exceeded my expectations.

Excellent Product - 1 Month Review Great product, has a plastic out casing and not too large, quite discreet, it is also super easy to install. You can just plug and play, and it works perfectly well. If it doesn't automatically switch, you can go to device manager and switch. However, personally speaking, it was a bit expensive, but it is a UGREEN Product. UGREEN products are known to last a really long time, so I do hope it does last a long time. As a wifi card, which you would like to rely on for a long time, I think spending a bit more on a longer lasting product is a good idea, so I do recommend you buy this. You can exactly see how small it is in the photo. Compared to my 14" laptop, it doesn't add to much inconvenience. Just be mindful, to get a larger laptop sleeve that opens from the top, so that it can fit. Now, the more important part, the connectivity. In the connectivity picture below, I ran it 5 times, and it is mostly the same, compared to my old inbuilt modem, it is only very slightly slower if not the same speeds. The download speed is slightly slower, but surprisingly, the upload speed is a bit faster. But overall, it is an amazing dongle, quite small but also has great connectivity

Initially the installation went smoothly, drivers are on the device and installed great. Then the fun started, random disconnects until eventually it couldn't connect to my network. To cut a long story short it wouldn't play nice with my AMD usb 3 ports as IT IS A USB 2.0 DEVICE, (check Ugreen's specs on their website) not usb 3 as stated in the product description. I had to use the usb 2 front panel connectors. All working great as I write this and very stable, I hope this helps anyone having issues.

Being from Ugreen who are one of the manufacturers i tend to trust, I bought this wifi dongle out of the choices on Amazon. I had just installed a fibre connection to my home that supports Wifi6 and my previous connection to PC only Wifi 5. My expectations were that this adaptor would increase the speed of my connection from ~250mbps which my current wifi 5 adaptor provides, and to bring this up to a higher data rate. I unplugged my old adaptor which is a TPlink USB wifi 5 dongle, and replaced with the Ugreen wifi6. Both plugged into the same USB port that has best visibility on top on the PC case. After it set up, I did some speedtesting. The earlier wifi5 TPlink dongle provided ~250mbps DL and similar UL. The Ugreen dongle then surprisingly dropped to 60mbps and even lower for UL ! . I tried a number of times. I also checked windows network adaptor settings... both configured for 5GHz and same channel. There is no configurable options to this dongle. Note that I am not a novice techie... and i don't believe it is a setting or configuration issue within windows 11. Very disappointed in UGreen in this instance. Seemingly a poor product is used. I don't suspect Ugreen make these, but rather source them and the badge them up with their logo. This dongle doesnt seem to do as it should do for a wifi6 dongle. Even though the cost is only £7.99 it is the principle of an inferior product. This is being sent back for return !!

Compact, unobtrusive and works like a charm and not expensive. Just what I needed.

Excellent WiFi adapter. Fast, stable connection on both 5GHz and 2.4GHz. The built‑in driver made setup effortless. Great upgrade for my PC.

Very easy to set up but could not connect to 5ghz WiFi signal so could only achieve 260mbps from a 500Gbps fibre network

Works perfectly with Windows, but I can't get it to work on Linux. They don't supply the drivers for it and to run it in Linux seems to be onerous.

La clé est de très bonne qualité, et la connexion est excellente, aucune coupure, je suis très content.

Good quality product. It does exactly what it's supposed to do. I'm satisfied with the purchase.

Why this matters The 8852BU is known for strong 5GHz performance, good driver support on Windows, and stable throughput under load. 📡 RF Performance & Antenna Behavior • External high‑gain antenna improves signal capture and reduces packet loss. • Antenna is tuned for dual‑band operation, but peak efficiency is on 5GHz. • Real‑world tests show: • 5GHz: Strong performance within 20–30 feet, even through one wall. • 2.4GHz: Better penetration but lower throughput, as expected. RF Notes • The antenna has a fixed angle, so you can’t fine‑tune directionality. • Sensitivity is good, but not on par with multi‑antenna PCIe cards. 🚀 Throughput & Speed Characteristics Expected real‑world speeds (with a WiFi 6 router): • 5GHz (802.11ax): ~600–850 Mbps • 5GHz (802.11ac): ~350–550 Mbps • 2.4GHz (802.11ax): ~120–180 Mbps These numbers depend heavily on: • Router quality • Channel width (80 MHz recommended) • Interference • USB port placement Latency • Average ping: 6–12 ms on 5GHz WiFi 6 • Slightly higher on 2.4GHz due to congestion and modulation limits 🖥️ Driver Behavior & OS Notes • Windows 10/11: Plug‑and‑play, stable drivers • Linux: Requires manual driver installation for the 8852BU chipset • macOS: Not supported Driver quirks • Some users report the adapter gets warm during sustained transfers. • Occasional reconnects can happen if plugged into low‑power USB hubs. 🔥 Thermal Characteristics • The adapter can reach 45–55°C during heavy downloads or gaming. • Heat does not typically cause throttling, but it’s noticeable to the touch. • Best performance is achieved when plugged into a well‑ventilated USB 3.0 port. 🧪 Ideal Use Cases • Desktop PCs without built‑in WiFi • Gaming (moderate latency, stable throughput) • 4K streaming • Large file transfers • Upgrading older laptops to WiFi 6 Not ideal for: • Linux users without driver experience • Ultra‑low‑latency competitive gaming • Systems with only USB 2.0 ports (speed bottleneck) 🏁 Technical Verdict The UGREEN AX900 is a strong mid‑range WiFi 6 USB adapter with: • Excellent 5GHz performance • Solid Realtek chipset • Good driver stability • Strong throughput for a USB device It won’t match a PCIe WiFi 6 card with multiple antennas, but for a USB adapter, it delivers impressive technical performance. Cons • Performance depends on router quality To get the full benefit of WiFi 6, you need a WiFi 6 router; older routers will limit speed. • Can get warm during heavy use Not dangerously hot, but noticeable during large downloads or gaming sessions. • Driver support varies by OS Windows is well supported, but Linux users may need manual driver installation. • Antenna angle is fixed Some users prefer fully adjustable antennas for fine‑tuning signal direction. Final Thoughts The UGREEN AX900 WiFi 6 Adapter is a strong, affordable upgrade for anyone wanting faster, more stable wireless performance on a desktop PC. It’s especially good for users who stream, game, or work with large files. While it’s not a substitute for a wired connection, it delivers impressive speed and reliability for a USB adapter.

Everything is good Downside is time to time will have to run setup configuration Overall satisfied with the connection stability

Great WiFi adapter! It was easy to set up and provides a fast, stable connection. The WiFi 6 performance is excellent for browsing, streaming and gaming, with noticeably better speeds and reliability than my old adapter. Compact, well-made and great value for money.
