Quick Verdict: Is the UGREEN AX900 Worth Your Money?
The UGREEN WiFi Dongle AX900 represents excellent value for anyone needing to upgrade an older device to WiFi 6 connectivity. During my testing, I consistently achieved download speeds of 480-520 Mbps on my 500 Mbps fibre connection, a massive improvement over the 120-150 Mbps I was getting with my laptop’s built-in WiFi 5 adapter.
What impressed me most wasn’t just the raw speed, but the stability. Video calls remained crystal clear even when other family members were streaming 4K content, and online gaming latency dropped noticeably. The external antenna makes a genuine difference, particularly if you’re connecting from a room distant from your router.

- Gamers seeking lower latency
- Anyone in a multi-device household
❌ Skip If:
- Your device already has WiFi 6 capability
- You need macOS or Linux support
- Your router only supports WiFi 5 or older
- You require enterprise-level features
- You’re on a very slow internet connection (under 50 Mbps)
What I Actually Tested
I put the UGREEN AX900 through rigorous real-world testing across three different scenarios to see how this high-speed wireless dongle performs under various conditions:
Test Setup 1: Desktop Gaming PC
Connected the adapter to my custom-built desktop (previously using ethernet) to test its capability as a wireless alternative. Router distance: approximately 8 metres through two walls. Internet connection: Virgin Media 500 Mbps fibre.
Test Setup 2: 2019 Dell Laptop
Replaced the built-in WiFi 5 adapter on a Dell XPS 13 from 2019. Router distance: 4 metres with one wall. Same internet connection.
Test Setup 3: Home Office Environment
Used in a converted garage office approximately 15 metres from the router through multiple walls and a brick exterior. This was the ultimate stress test for the 6dBi antenna’s range capabilities.
Over three weeks, I conducted speed tests at different times of day, ran multiple video calls simultaneously, streamed 4K content, played online games (Valorant and Warzone), and transferred large files across my network. I also tested the hotspot functionality by using my desktop to share its connection with my tablet.
Price Analysis: What You’re Actually Paying For
At £10.97, the UGREEN WiFi Dongle AX900 sits in an interesting position. It’s not the cheapest WiFi 6 adapter on the market, but it’s far from the most expensive. The 90-day average price of £14.47 suggests relatively stable pricing, though you’re currently paying slightly above that average.
To put this in perspective, the TP-Link Archer T9UH typically retails around £35-40, whilst the Netgear A7000 commands £45-55. The UGREEN offers similar WiFi 6 performance at roughly half the price of these premium competitors. Where you might notice the cost difference is in build quality (more plastic, less metal) and the single antenna design versus dual antennas on pricier models.
However, for most home and office users, these compromises are negligible. During my testing, I couldn’t justify spending double the money for perhaps 10-15% better performance in edge cases. The value proposition here is genuinely compelling, especially considering WiFi 6’s efficiency improvements over previous standards.
Installation and Setup: Genuinely Plug-and-Play
UGREEN claims the AX900 features built-in drivers for Windows 10 and 11, eliminating the need for CD installation or manual driver downloads. I was sceptical, having been burned by similar claims before, but I’m pleased to report this actually works as advertised.
On my Windows 11 desktop, I plugged the dongle into a USB 3.0 port (the blue ones for maximum speed), and within 45 seconds, Windows had automatically detected and installed the necessary drivers. A small notification appeared confirming the UGREEN WiFi adapter was ready to use. No restart required.
The Windows 10 laptop took slightly longer, around 90 seconds, but still required zero intervention on my part. I simply clicked the WiFi icon in the system tray, selected my network, entered the password, and was online immediately.
One important note: the adapter does protrude about 12cm from your USB port when the antenna is attached. If you’re using a laptop, this means it sticks out quite noticeably. It’s not really designed for mobile use; you’ll want to remove it before throwing your laptop in a bag. For desktop users, this is a non-issue.
The antenna itself is adjustable, rotating 180 degrees. I found positioning it vertically gave the best results in most scenarios, though horizontal positioning worked better when my router was on a different floor.
Performance Testing: Speed, Range, and Stability
Raw Speed Performance
Using Ookla’s Speedtest across multiple testing sessions, here’s what I consistently achieved:
5GHz Band (Close Range, 4 metres):
Download: 480-520 Mbps
Upload: 68-72 Mbps
Ping: 8-11 ms
5GHz Band (Medium Range, 8 metres through two walls):
Download: 380-420 Mbps
Upload: 62-68 Mbps
Ping: 10-14 ms
2.4GHz Band (Long Range, 15 metres through multiple walls):
Download: 145-180 Mbps
Upload: 38-45 Mbps
Ping: 15-22 ms
These results are impressive for a portable WiFi receiver at this price point. The AX900 nearly maxed out my 500 Mbps connection when close to the router, and maintained usable speeds even in my challenging garage office scenario.
Real-World Usage Scenarios
Video Conferencing: I conducted over 30 hours of Zoom, Teams, and Google Meet calls during testing. Video quality remained consistently high at 1080p, with no dropped frames or connection interruptions. Even when my partner was streaming Netflix in 4K simultaneously, my calls remained stable. The low latency of WiFi 6 technology genuinely makes a difference here.
Gaming Performance: I tested Valorant and Warzone extensively. Ping times averaged 12-18 ms on European servers, with zero packet loss over multiple gaming sessions. This is comparable to my wired ethernet connection, which typically gives me 8-12 ms. For competitive gaming, you’ll still want ethernet if possible, but this adapter is more than adequate for casual to intermediate players.
4K Streaming: No buffering whatsoever on YouTube, Netflix, or Amazon Prime Video. 4K content loaded within 2-3 seconds and played smoothly throughout. I even tested streaming 4K content on two devices simultaneously, and both maintained perfect playback.
Large File Transfers: Transferring a 25GB video file from my NAS to my desktop took approximately 8 minutes over the 5GHz band. That’s roughly 52 MB/s, which is respectable for wireless transfer, though obviously slower than gigabit ethernet (which would manage this in about 4 minutes).
The 6dBi Antenna Advantage
The external antenna is where the UGREEN AX900 differentiates itself from cheaper alternatives. I compared it directly against a friend’s TP-Link adapter with an internal antenna, and the difference was measurable.
In my garage office (the challenging 15-metre scenario), the UGREEN maintained a connection with download speeds of 145-180 Mbps. The TP-Link adapter struggled to maintain a stable connection at all, frequently dropping to 2.4GHz and achieving only 60-80 Mbps when it did connect.
The ability to adjust the antenna angle is more useful than I initially expected. Pointing it towards the router’s location (even through walls) consistently improved signal strength by 10-15% according to Windows’ WiFi analyser tool.
WiFi 6 Technology: What’s Actually Different?
WiFi 6 (802.11ax) isn’t just about raw speed increases. According to the Wi-Fi Alliance, the standard introduces several technologies that improve performance in congested environments, which is where I noticed the most significant benefits.
OFDMA (Orthogonal Frequency Division Multiple Access) allows the router to communicate with multiple devices simultaneously rather than sequentially. In practical terms, this meant my video calls didn’t suffer when other household members started streaming or downloading large files.
Target Wake Time (TWT) improves efficiency, though this is more relevant for battery-powered devices. MU-MIMO support means the adapter can handle multiple data streams, reducing latency when multiple applications are using the network simultaneously.
During my testing, the most noticeable benefit was consistency. With my old WiFi 5 adapter, speeds would fluctuate wildly depending on network congestion. The AX900 maintained much more stable performance throughout the day, even during peak evening hours when everyone in my household was online.
How It Compares to the Competition
| Feature | UGREEN AX900 | TP-Link Archer T9UH | Netgear A7000 | D-Link DWA-X1850 |
|---|---|---|---|---|
| WiFi Standard | WiFi 6 (802.11ax) | WiFi 5 (802.11ac) | WiFi 6 (802.11ax) | WiFi 6 (802.11ax) |
| Max Speed | 900 Mbps | 1900 Mbps | 1800 Mbps | 1800 Mbps |
| Antenna Design | External 6dBi (1x) | External (4x) | Internal | External (2x) |

| Dual-Band | Yes | Yes | Yes | Yes |
| Hotspot Mode | Yes | No | No | Yes |
| Typical Price | £16.99 | £38.99 | £49.99 | £32.99 |
The comparison reveals the UGREEN’s positioning clearly. It sacrifices maximum theoretical speed (900 Mbps versus 1800+ Mbps on competitors) but delivers WiFi 6 technology at a significantly lower price point. For most home internet connections in the UK (averaging 50-100 Mbps according to Ofcom data), the AX900’s 900 Mbps capability is more than sufficient.
The TP-Link Archer T9UH offers higher speeds but uses older WiFi 5 technology, meaning you miss out on the efficiency improvements and better congestion handling that WiFi 6 provides. The Netgear A7000 is genuinely excellent but costs three times as much. The D-Link DWA-X1850 is perhaps the closest competitor, offering similar WiFi 6 performance at roughly double the price.

This adapter isn’t suitable for:
Mac Users: UGREEN doesn’t provide macOS drivers, and the built-in driver functionality is Windows-specific. Mac users should look at alternatives like the TP-Link Archer series with official macOS support.
Linux Enthusiasts: Whilst some users report success getting the adapter working on Linux distributions, it’s not officially supported and requires manual driver compilation in most cases.
Maximum Performance Seekers: If you have gigabit internet (1000 Mbps+) and want to fully utilise it wirelessly, you’ll need an adapter with higher theoretical maximums. The AX900’s 900 Mbps combined speed will become a bottleneck.
Frequent Travellers: The protruding antenna and lack of protective case make this impractical for regular transport. You’d be better served by a compact USB adapter with an internal antenna, accepting the range trade-off.
Technical Specifications Worth Knowing
Beyond the marketing specifications, here are some technical details that matter:
Chipset: The adapter uses a Realtek RTL8832AU chipset, which is a proven WiFi 6 solution found in many mid-range adapters. It’s not the absolute latest generation, but it’s mature and stable.
Security: Supports WPA3 encryption, the latest WiFi security standard. This provides improved protection against brute-force attacks compared to WPA2. Your router must also support WPA3 to take advantage of this.
Power Consumption: The adapter draws approximately 2.5W during active use, which is standard for this class of device. It supports USB selective suspend for power saving when idle.
Operating Temperature: Rated for 0-40°C operation. During my testing in a 22°C room, the adapter reached approximately 45°C during sustained file transfers, which is warm but within safe operating parameters.
Dimensions: The main body measures 58mm x 28mm x 12mm, with the antenna adding approximately 120mm when attached. Total weight is 28 grams.
Tips for Optimal Performance
After three weeks of testing, here are my recommendations for getting the best results from the UGREEN AX900:
1. Use a USB 3.0 Port: The blue USB ports on your device support higher data transfer rates. Plugging into a USB 2.0 port (black) will bottleneck performance significantly.
2. Position the Antenna Thoughtfully: Point the antenna towards your router’s location for optimal signal. I found vertical positioning worked best when the router was on the same floor, whilst horizontal positioning improved results when connecting between floors.
3. Prioritise 5GHz When Possible: The 5GHz band offers significantly higher speeds. Only fall back to 2.4GHz when range becomes an issue. Windows should handle this automatically, but you can manually select the band in network settings if needed.
4. Keep Drivers Updated: Whilst the built-in drivers work well, checking UGREEN’s download centre periodically for driver updates can improve performance and stability.
5. Consider a USB Extension Cable: If your USB ports are located in an awkward position (like the back of a desktop PC against a wall), a short USB 3.0 extension cable allows you to position the adapter for better signal reception.
Final Verdict: Should You Buy the UGREEN WiFi Dongle AX900?
After extensive testing, I’m genuinely impressed by what UGREEN has achieved at this price point. The AX900 isn’t perfect (the Windows-only limitation and protruding design are legitimate drawbacks), but it excels at its primary purpose: providing fast, stable WiFi 6 connectivity to devices that lack it.
For desktop PC users, this is a no-brainer purchase. For laptop users with older WiFi cards, it’s an excellent upgrade provided you’re primarily using your device in a fixed location. The performance improvements I experienced were substantial and consistent across all testing scenarios.
The 1,510 customer reviews averaging 4.4 stars reflect genuine satisfaction from real-world users, and my testing experience aligns with this positive reception. This is a product that simply works as advertised, which is refreshingly uncommon in the budget tech accessory market.
If you’re running Windows 10 or 11, have a WiFi 6 router (or plan to upgrade to one), and need reliable wireless connectivity, the UGREEN WiFi Dongle AX900 deserves serious consideration. It won’t win awards for aesthetics or portability, but it will transform your network experience in meaningful, measurable ways.
