Low latency for online gaming
I was skeptical about using a USB adapter for competitive gaming, but the latency is surprisingly low on the 5GHz band. Downloads are fast, and I haven't experienced any dropouts during long sessions. Highly recommend for gamers on a budget.

Perfect upgrade for my old desktop
My old desktop didn't have built-in WiFi, and running an Ethernet cable was a hassle. This Mercury UX3 card solved the problem instantly. Plug and play worked perfectly on Windows 11 without needing any discs or downloads. The 5G band gives me full speed for gaming.

Easy setup for the whole team
Bought five of these for our small office laptops. Setup was incredibly fast for non-tech staff; just plug it in and connect. The dual-band feature helps reduce congestion when everyone is online. Very reliable product.

Good speed, gets a little warm
Does exactly what it says. Streaming 4K content works smoothly without buffering. I noticed the device gets slightly warm after a few hours of heavy use, but it doesn't seem to affect performance. Good purchase for the price.

Saved my work-from-home setup
My internal WiFi card died, and this was a cheap, effective replacement. The external antennas provide much better reception than my laptop's internal card ever did. Driver-free installation was a huge plus since I couldn't download drivers easily.

Great signal strength, slightly bulky
The connection is very stable even through two walls from my router. Video calls are crystal clear now. The only downside is that the antennas make it a bit large, so it might block adjacent USB ports on a laptop. Otherwise, excellent value.
Q: Can this adapter create a hotspot?
A: Yes, provided your operating system supports the 'Mobile Hotspot' feature, you can use this adapter to share your wired or wireless internet connection with other devices.
Q: Does it support 5GHz WiFi networks?
A: Absolutely. The UX3 is a dual-band adapter that supports both 2.4GHz and 5GHz frequencies, allowing you to choose the less congested 5GHz band for higher speeds.
Q: Is this compatible with Mac computers?
A: Yes, the Mercury UX3 is compatible with macOS. It supports driver-free installation on most modern versions of macOS, allowing you to connect immediately after plugging it in.
Q: What is the maximum range of this adapter?
A: While range depends on your environment and router, the high-gain external antennas typically provide a stable connection up to 30-50 meters indoors in open spaces. Walls and interference may reduce this distance.
Q: Do I need to install drivers for Windows 10?
A: No, this is a driver-free model for Windows 10 and Windows 11. The necessary drivers are built into the operating system, so it will be recognized automatically upon insertion.
