300Mbps USB 2.0 Wi-Fi adapter

The sakose RTL8192FU N9100 is a USB 2.0 wireless adapter built around the Realtek 8192FU chipset. It targets desktop or laptop users who need to add or upgrade 2.4GHz Wi-Fi connectivity on systems running Windows XP through Windows 10 or Linux. The device includes two detachable 5dBi RP-SMA dipole antennas and an 80cm extension cable for flexible placement. It draws power directly from the USB port and requires no external supply.

Capacity and headroom

The adapter supports IEEE 802.11b/g/n with a maximum PHY rate of 300Mbps on the 2.4GHz band. Real-world throughput will be lower due to protocol overhead, interference and the USB 2.0 bus limit. The 5dBi antennas and adjustable transmit power up to 2000mW extend coverage compared to basic internal adapters, but dense walls or long distances will still reduce usable speed. It does not support the 5GHz band or 802.11ac/ax standards.

USB 2.0 interface limits

The USB 2.0 Hi-Speed interface caps sustained throughput well below the 300Mbps radio rate, so file transfers and streaming will typically peak at USB 2.0 bulk-endpoint limits. The adapter operates from 0°C to 40°C and stores from -40°C to 70°C. Security is limited to WEP, WPA/WPA2 and WPA-PSK/WPA2-PSK with TKIP or AES; WPA3 is not supported. Buyers needing 5GHz operation, higher throughput or modern security protocols should consider a different adapter class.

Questions about this item

Will the USB 2.0 interface on this adapter work with my older USB 1.1 ports?

Yes, the adapter is USB 2.0 compliant and backwards compatible with USB 1.1 ports.

How can I verify the adapter is transmitting at the full 300Mbps rate after installation?

Check the connection properties in your OS; a 300Mbps link speed confirms the 802.11n connection is active at the maximum rate.

Does the package include the two 5dBi antennas and the 80cm extension cable, or must I buy them separately?

The box contains the adapter, two 5dBi RP-SMA dipole antennas, an 80cm USB extension cable, a driver CD and a user manual.
