Designed as a mini AX600 WiFi 6 USB adapter with Bluetooth 5.4, the CF-731B brings WiFi reception, WiFi sharing, and Bluetooth connectivity together in one small device. It is built for daily users who want easier networking at home, in the office, in a dorm room, or while traveling.
Small Size, More Wireless Possibilities
The CF-731B uses a compact USB 2.0 design, making it easy to plug into a laptop or desktop computer without taking up much space. With its portable body and clean blue exterior, it is suitable for users who need a wireless upgrade that is simple, lightweight, and easy to carry.
For desktop PCs without built-in WiFi, the CF-731B helps remove the need for long Ethernet cables. For laptops, it can serve as a convenient wireless solution when the built-in network module needs an upgrade or replacement.
AX600 WiFi 6 for Smoother Daily Connections
The CF-731B supports the IEEE 802.11a/b/g/n/ac/ax wireless standards and adopts WiFi 6 technology for a faster and more efficient wireless experience. It supports both 2.4GHz and 5.8GHz bands, delivering a combined wireless rate of up to 572Mbps.
The 2.4GHz band helps provide broader wireless coverage, while the 5.8GHz band is better suited for faster browsing, smoother streaming, online meetings, and everyday downloads. This dual-band flexibility allows users to choose the right connection for different network environments.
With AX600 WiFi 6 performance, the CF-731B is designed for everyday tasks such as web browsing, video calls, online learning, streaming, file downloads, and wireless access for desktop PCs.
WiFi Reception and WiFi Sharing in One Adapter
The CF-731B is more than a basic wireless receiver. It supports both WiFi receiving and WiFi transmitting functions, giving users more flexibility in different situations.
When used as a WiFi receiver, it allows a desktop PC to connect to a wireless network without pulling a network cable across the room. When used with simulated AP mode, it can help share a network connection with other devices such as smartphones, tablets, and laptops, making it useful for temporary wireless sharing at home, in dormitories, or during travel.
Bluetooth 5.4 for Wireless Peripherals
In addition to WiFi, the CF-731B also supports Bluetooth 5.4, allowing users to connect Bluetooth headphones, speakers, mice, keyboards, and other wireless peripherals.
This makes the adapter especially useful for desktop computers that do not have built-in Bluetooth. Users can enjoy wireless audio, cleaner desk setups, and more convenient peripheral connections through one compact USB device.
Stable Chipset, Built-In Antenna, Secure Connection
The CF-731B is built with the AIC8800M40B chipset solution and an internal 2dBi antenna design for stable signal reception and transmission. Its low-power design also helps reduce unnecessary energy consumption during daily use.
For wireless security, the adapter supports multiple encryption methods, including WPA-WEP, WPA-PSK, WPA2-PSK, and WPA3. This helps users maintain a safer wireless connection whether they are working from home, studying online, or connecting in a shared network environment.
