UGREEN Wifi Dongle, AX900 WiFi 6 Adapter Dual Band 5GHz/2.4GHz for PC | Built-in Driver, OFDMA+MU-MIMO Technology, 900Mbps Speed, Low Latency Gaming, Supports Windows 10/11, Plug and Play

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.LinuxA 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/linuxmintSo yeah, the painless windows setup, fast and consistent speed and ping, plus linux compatibility makes for a versatile product that well exceeded my expectations.

Grabbed this to fix a spare netbook with a dead WiFi driver, and it just worked: plugged in, connected within seconds, no driver hunting or setup hassle. Having both WiFi and Bluetooth in one small dongle is the real win here since it doesn't stick out or get in the way. Got it on sale for £7.99 (down from £10.99).I only use it for casual browsing on the netbook, anything needing a stable connection goes through a wired PC, but for that it's had zero issues so far. Solid little fix for an old laptop.

I picked up this USB Wi‑Fi 6 dongle for my backup mini PC, mainly as a low cost solution to keep it online without running extra cables. For something this cheap, I wasn’t expecting much but it’s actually been a pleasant surprise.The connection holds steady at around 300 Mbps on my 1 Gb fibre line, which is more than enough for streaming, remote access, updates, and general day to day use. It’s stable, doesn’t randomly drop out, and the setup was completely painless. Plug it in, install the driver, and it just works.Of course, it won’t replace a proper internal Wi‑Fi card or wired connection, but for a budget USB adapter, the performance is genuinely impressive. If you need a simple, reliable way to get a spare PC online without spending much, this little dongle does the job far better than expected.

Device is unstable and will connect and disconnect at intervals of 5 mins, I have contacted UGREEN and I have been told to take it uo with Amazon, Guess I am not getting my money back on this?I usually have a great experience with UGREEN products, but this has to be the worst device I have used.The USB Wifi Dongle is poor with signal and poor with performance, I don't recommend this product.There are far better products and companies out there with better customer service that this.The speed of the connection is poor.The device needs to install via it's device folder.It's small, not micro in size but small enough to be hidden behind the computer.The item gets hot very quickly, overheating is it's downfall.I suggest you look elsewhere.,

So far so good. It will allow me to keep the spare W10 laptop used for streaming (while ironing etc) going for a while longer. Initially, I couldn't find the new router and thought it wouldn't work (laptop has wifi2only, it's that old). But I used to work in the sector in the 80s, so I persisted. This time I opened This PC, found the setup, and initialised it. Still had a problem. So I installed the network manually, giving it a second WPA. Bingo. Works like a charm now. Good Mbps in a poorish area. Streams like a dream. I will edit if I get issues. If this seems simplistic, sorry, I'm 80+ and proud of myself.

Didn't work on my ChromeOS Flex HP pavilion Computer...

It's really cheap, and can go above 5G, but that's about it, it's only good for laptops + you need to set it up due to having a file, for PC.....might as well get a bigger but only 5G dongle.

For the price, this is a very good product. The driver is built into the USB stick itself. At first, it may seem like the USB network device isn’t recognized, but there’s no need to worry. When you plug it in, a new drive appears on your Windows PC. Simply open that drive, double-click the setup file, and installation completes within seconds.In terms of speed, performance will vary depending on the USB port used. Connected to a USB 2.0 port, I achieved speeds of up to 240 Mbps. On USB 1.0, speeds were around 40 Mbps for both upload and download, which is still decent for most HD streaming. Not tested on USB 3.0 but likely to get 400+ speeds . if you have a device with 3.0 socket , not likely you will require this anyways as the PC would have onboard cards to support Dual Band (2G+5G) .I haven’t experienced any connection drops so far, suggesting it provides a stable and reliable connection.

c'est parfait

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

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.

Item arrived on time. Item is as described and works perfectly.

This UGREEN WiFi 6 adapter is a fantastic solution for adding high-speed wireless connectivity to a desktop or laptop without an internal card. The setup was plug-and-play on my Windows 11 system, and the signal strength is impressively strong and stable even through multiple walls. I've noticed a significant improvement in both download speeds and latency during online gaming compared to my old WiFi 5 dongle. The compact design doesn't block adjacent USB ports, and the build quality feels solid and reliable. It's a very cost-effective way to take advantage of WiFi 6 speeds; I highly recommend it for a hassle-free network upgrade.
