The UGREEN AC1300 USB WiFi Adapter (Model CM492 or 50340) is a dual-band wireless solution that provides speeds of up to 867 Mbps on the 5 GHz band and 400 Mbps on 2.4 GHz. To ensure peak performance and stability, keeping its driver updated is essential. Quick Download & Compatibility
The adapter uses either the RTL8812AU or RTL8812BU chipset depending on the specific hardware version.
Windows 11/10: Generally Plug & Play; drivers often install automatically upon connection.
Older Windows (7/8/8.1/XP): Driver installation is required.
macOS (10.11 - 10.15): Manual installation is required. Note that it typically does not support Apple M-series (M1/M2/M3) chips.
Official Downloads: You can find the latest official drivers on the UGREEN Support Page by searching for your product's model number (e.g., 50340). How to Update Your Driver Method 1: Automatic Update (Windows 10/11)
If you are experiencing connection drops, try updating through Windows: Open Device Manager (right-click the Start button). Expand Network adapters.
Right-click your UGREEN AC1300 or Realtek Wireless entry and select Update driver. Choose Search automatically for drivers. Method 2: Manual Installation If automatic updates fail or you are on an older OS:
It wasn’t the sort of notification Michael expected to change his week. Just a small gray bubble in the corner of his Linux desktop: “ugreen ac1300 usb wifi adapter driver updated.”
He clicked “remind me later” and went back to his coffee.
Michael lived on the edge of a town that had forgotten its own name—literally. The sign at the welcome center had been blank since the ‘90s. His internet came from a single, stubborn cell tower six miles away, filtered through a window-mounted antenna and then into his desktop. The UGREEN AC1300 was his lifeline: a small, shark-fin-shaped USB adapter that clung to the 5GHz band like a barnacle to a shipwreck. Without it, he might as well send messages via crow.
The driver had been a problem for two years. It worked, sort of, but it dropped packets whenever the wind blew from the north. Video calls stuttered into cubist paintings. Downloads failed at 99%. Michael had written a small script called pray.sh that restarted the network stack every 17 minutes. He’d grown used to it—the same way you grow used to a limp.
But that morning, something was different.
He finished his coffee, sighed, and ran the update. Terminal output scrolled past—compiling module… installing… cleaning up…—then silence. He rebooted out of habit, not hope.
When the desktop reappeared, the Wi-Fi icon showed three solid arcs.
“Huh,” he said.
He opened a terminal and pinged Cloudflare: 64 bytes from 1.1.1.1: time=12.4 ms. He blinked. Twelve milliseconds. The old driver had never dipped below 90. He tried a 4K video stream—a nature documentary about deep-sea jellyfish. It played instantly, frame after silken frame. No buffer. No pixelation. The jellyfish pulsed like captive stars.
Michael sat back. The pray.sh script sat on his desktop, suddenly useless. He deleted it. Then, on a whim, he joined a video call with a colleague in Melbourne. For the first time in two years, he didn't have to say, “Sorry, can you repeat that? My connection glitched.”
The silence on the line was just silence. Not lost packets.
That night, he didn't go to bed. Instead, he started pulling old files from a forgotten backup—a novel he’d abandoned because the cloud sync kept corrupting chapters. The UGREEN adapter hummed softly, its LED a steady blue. By 3 a.m., he’d recovered seven lost chapters and written a new one: about a man who built a radio telescope in his backyard and accidentally heard the quiet hum of a dead star.
The next day, a package arrived. He hadn’t ordered anything. Inside: a new UGREEN AC1300, identical to his own, with a note card that read only: “Thank you for not giving up on the driver. The jellyfish were beautiful.”
Michael turned the card over. On the back, a hand-drawn diagram of his network stack, annotated in a tight, engineering script. At the bottom: “The update was for you. All 847 lines of it. — A.”
He never found out who “A” was. But every time the adapter’s blue light blinked, he imagined someone, somewhere, compiling a fix at 2 a.m. because they knew he was out there, watching jellyfish, trying to write, hoping for a signal.
The driver never needed another update. And Michael’s novel, The Last Quiet Place, ended with a line he’d written that first perfect night:
“Sometimes a connection is just a connection. But sometimes, it’s a conversation you didn’t know you were having.”

UGREEN Wi-Fi Adapter Driver Installation Guide - Manuals.plus
Updating the driver for your UGREEN AC1300 USB WiFi Adapter (often model 50340 or 50341) ensures peak performance and stability on your network . While newer systems like Windows 10 and 11 are often plug-and-play, older versions or troubleshooting scenarios may require a manual update to the latest manufacturer software . Update Methods by Operating System Windows (11, 10, 8.1, 8, 7)
Here are a few options for the text draft, depending on where you intend to publish it (e.g., a blog post, a press release, or a support knowledge base article).
Speed & Throughput The AC1300 standard (up to 867 Mbps on 5GHz) is plenty for a home office setup. Post-update, the adapter handles 4K YouTube streaming without buffering. Transferring files from my NAS (Network Attached Storage) is now significantly snappier, averaging around 30-40 MB/s write speeds over WiFi, which is impressive for a USB 2.0 interface device.
Range & Signal Strength The adapter has two external antennas. With the new drivers, these actually seem to function correctly. I am one room away from the router, and I now have a full signal bar in the Windows network menu. Previously, with the old driver, it showed 3 bars. The signal management is much better now, intelligently locking onto the 5GHz band rather than constantly drifting to the slower 2.4GHz band.
Thermals One thing the driver update didn't fix is that this thing runs warm. It isn't dangerously hot, but it is noticeable to the touch after heavy use. This seems to be a hardware design choice, not a software issue.
If the automatic installer fails, use Device Manager:

The UGREEN AC1300 requires a proprietary driver. The updated driver is maintained by the community (Morrownr’s 88x2bu driver).
git clone https://github.com/morrownr/88x2bu-20210702.git
cd 88x2bu-20210702
sudo ./install-driver.sh
Before diving into the drivers, let’s appreciate the hardware. The UGREEN AC1300 is based on the Realtek chipset (often the RTL8812BU or RTL8821CU variant). It supports:
But to unlock these speeds on Windows 11, Windows 10, Linux, or macOS, you need the latest updated drivers.
As of early 2025, here are the stable, updated driver versions you should be running:
