Connect up to five devices simultaneously: The adapter connects up to five Bluetooth devices at the same time — headphones, speakers, keyboards, mice, and game controllers — without devices interfering with each other. Note that two audio output devices of the same type, such as two headphones, cannot play audio simultaneously; only one will be active at a time.
Plug and play on Windows: No driver installation is required under Windows 11, 10, or 8.1. Plug the dongle into a free USB port and Windows recognises it immediately, showing a Bluetooth icon in the system tray.
20-metre wireless range: Keep your Bluetooth devices within 20 metres (66 feet) of the adapter in open space. Additionally, the nano-sized form factor sits flush against the chassis, leaving adjacent USB ports unobstructed.
Broad Bluetooth profile support: Supported profiles include A2DP, HSP, AVRCP, HID, PAN, GAVDP, DID, and IOPT, covering audio streaming, headset calls, media controls, and human interface devices in a single dongle.
867Mbps on 5GHz via USB 3.0: The AC1300 rating delivers 867Mbps on 5GHz and 400Mbps on 2.4GHz — a stable experience comparable to a wired network, provided the adapter connects to a USB 3.0 port. Connecting to a USB 2.0 port limits throughput, so users should confirm port colour (blue inside indicates USB 3.0) before plugging in.
WPS one-click secure connection: The built-in WPS button connects to any WPS-capable router with a single press, without requiring a password. This reduces setup time in environments where multiple users configure their own machines, and the WPS standard additionally adds a layer of session security during the pairing exchange.
Soft AP mode — use the PC as a wireless hotspot: Station Mode and Soft AP mode operate simultaneously. In Soft AP mode, the adapter converts a wired computer into a Wi-Fi hotspot for other devices to share the connection. This is a practical feature for offices or hotel rooms with only a wired Ethernet drop.
Broad OS compatibility including macOS: Unlike the CM496 AC650, the CM492 supports Windows 11, 10, 8.1, 8, 7, and macOS 10.11 and above — with plug-and-play driver-free operation on Windows 10 and 11 only. Note that Apple M1, M1 Pro, and M1 Max MacBooks are not compatible.
Mini form factor at 85 × 25 × 8 mm: The compact dongle size of 85 × 25 × 8 mm means it fits in an office bag or pocket, and remains inconspicuous when left plugged into a laptop port. Furthermore, the low-profile design does not block adjacent USB ports on most machines.
433Mbps on 5GHz and 200Mbps on 2.4GHz: 433Mbps on the 5GHz band suits lag-free online gaming and 4K Ultra HD video streaming, while 200Mbps on 2.4GHz handles everyday tasks such as web browsing and connectivity with legacy devices. The adapter switches between bands automatically, so users do not need to manage band selection manually.
Integrated PIFA antenna in a nano form factor: The CM448 uses an integrated PIFA antenna and measures 40 × 19 × 9 mm — small enough to sit completely flush with a laptop chassis without protruding into adjacent USB ports or snagging on a laptop bag. This distinguishes it from the CM496, which requires an external antenna for extended range.
Plug and play on Windows 10 and 11: Windows 10 and 11 support the CM448 driver-free. For Windows 7, 8, 8.1, Linux, and macOS 10.11–11.6, a driver installation is required. The adapter includes a mini-CD and the driver is additionally available from the UGREEN download centre using model number 20204.
Soft AP mode for shared wireless access: The CM448 supports Station Mode and Soft AP mode simultaneously. In Soft AP mode, it converts a wired computer into a Wi-Fi hotspot for other devices to connect through. This requires an active internet connection on the host machine and the driver to be installed before the Soft AP function becomes available.
Dust protection cap included: The adapter includes a dust protection cap, which prevents connector oxidation and physical damage when the dongle is carried loose in a bag or not in use. Additionally, the blue LED indicator provides instant feedback on driver installation status and connection state.
6dBi high-gain rotatable antenna: The external high-gain antenna supports 90-degree and 180-degree rotation, allowing users to physically orient it for the strongest available signal. This makes a practical difference in environments with thick walls, interference from adjacent networks, or a router positioned at an awkward angle relative to the PC.
Dual band 5GHz and 2.4GHz with auto-switching: 433Mbps on 5GHz suits lag-free online gaming and 4K Ultra HD video streaming, while 200Mbps on 2.4GHz handles everyday tasks such as web browsing and legacy device compatibility. The adapter switches bands automatically, so users do not need to manage this manually.
Soft AP mode — convert a wired PC into a Wi-Fi hotspot: The adapter supports Station Mode and Soft AP mode simultaneously. In Soft AP mode, a wired computer converts into a Wi-Fi hotspot for other devices to use. This is a practical feature for offices or households where one machine has a wired connection and nearby devices need wireless access.
Realtek RTL8811CU chipset with built-in driver: The RTL8811CU chip provides excellent compatibility and compact size, with strong performance at low power consumption. On Windows 11 and 10, the built-in driver means no CD or manual driver download is required — plug in and connect.
Blue LED status indicator: The blue indicator light does not illuminate when the driver is not installed; once installed and disconnected, it flashes slowly; when connected to Wi-Fi, it flashes quickly — providing clear, immediate feedback on the adapter's operational state without requiring software.
One-button auto-lock: The click-in mechanism secures the phone automatically on insertion, and a single press of the release button removes it — no side clips or manual tightening required.
360° ball-joint rotation: Adjust to portrait, landscape, or any angle in seconds; the joint holds position firmly without creeping under vibration.
Wide phone compatibility (4.7–6.8 inches): Works with most current smartphones in a standard protective case, up to 162.2 mm long and 12 mm thick.
Silicone-padded arms and clamp: Protects the phone from scratches at all contact points and prevents the mount rotating on the handlebar.
Tool-free clamp for 15–44 mm bars: Fits road bikes, MTB, motorcycles, scooters, and e-bikes; transfers between vehicles in under a minute.
Gigabit full-duplex throughput: The card supports maximum data transfer speeds of 1000 Mbps in each direction, totalling 2000 Mbps — up to ten times faster than standard 10/100 Ethernet. This eliminates the bottleneck that older integrated NICs create on high-speed broadband connections.
Realtek RTL8111H chipset with jumbo frame support: The Realtek RTL8111H chipset delivers low latency and high throughput, while jumbo frame support up to 9K and link-layer traffic offload reduce CPU utilisation during sustained data transfers — a practical benefit for NAS access, file servers, and virtualised workloads.
Universal PCIe slot compatibility: The card fits any PCI Express x1, x2, x4, x8, or x16 socket, making it compatible with virtually all modern desktop motherboards regardless of available slot configuration.
Dual bracket design for standard and compact cases: The package includes a 12 cm standard-height bracket and an 8 cm low-profile bracket. This allows installation in a wide range of computer and server cases, including compact HTPCs and small form factor builds where a standard-height card would not fit.
VLAN tagging and Wake-on-LAN support: The adapter handles VLAN tagging via 802.1Q for segmented network environments, and additionally supports Wake-on-LAN, allowing administrators to power on a machine remotely over the network — useful in home lab, small business, and managed office deployments.
