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.

Excellent Product - 1 Month ReviewGreat 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.

Seemed great to start with but then it started to constantly loose the connection (great signal strength) and also disconnect from the PC. The only way to get it working again was to unplug it and re-plug it.The driver install was easy - just as well since I must have uninstalled it and re-installed it twenty times! I even tried the driver from the UGreen website. All to no avail, it just constantly drops out and disconnects. And yes - I did turn of energy saving in device manager for both the device and USB. A shame because when it worked the speed was good for the money. Now using an old WiFi 5 dongle I found in a draw which works flawlessly.

UGREEN WiFi Dongle AX900 works perfectly. Gave new life to an old laptop that wouldn't connect to new WiFi router. A small amount of money well spent!

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

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.

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.

Für W11 ohne Probleme. Falls Treiber nötig waren, hat er sie im Hintergrund gezogen. Geschwindigkeit: bei 5 ist 600 MB, bei2 70. Entfernung 2 m. Reicht für Standard

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.
