Compact USB Wi-Fi adapter

The JacobsParts DONGLE-D adds 802.11ac dual-band wireless to any device with a USB port. It delivers up to 600 Mbps combined throughput with 433 Mbps on 5.8 GHz and 150 Mbps on 2.4 GHz. The tiny 3.15 x 0.79 x 1.18 inch dongle weighs only 0.07 ounces and uses a USB 2.0 interface. A RTL8811CU chipset provides 1T1R MIMO capability and Soft AP support.

Best for basic wireless upgrades

This adapter suits users who need simple Wi-Fi on older laptops, desktops or Linux machines without internal cards. It works with Windows 10, Windows 7, Windows XP and Linux using downloadable drivers. Buyers who want more bandwidth, newer Wi-Fi standards or Bluetooth functionality should look at something else. The USB 2.0 link also limits peak throughput compared to faster host interfaces.

Sustained connection behaviour

Under continuous load the USB 2.0 bus caps real-world speed well below the 600 Mbps link rate. The small form factor has minimal surface area for heat dissipation during long transfers. Driver stability on Linux depends on the community-maintained RTL8811CU driver from the supplier or GitHub. Performance stays consistent for typical browsing and streaming but drops during heavy sustained traffic.

Questions about this item

What USB port version does the DONGLE-D need for its 600Mbps link?

The adapter uses a USB 2.0 interface so it will operate on any USB 2.0 or 3.0 port, though throughput stays at the USB 2.0 ceiling.

Will the DONGLE-D connect to my older 802.11n router on the 2.4GHz band?

Yes, the dongle is backwards compatible with 802.11a/b/g/n and will fall back to 150Mbps on 2.4GHz when linked to an 802.11n access point.

How do I confirm the RTL8811CU chipset is active after installing the driver?

Open Device Manager on Windows or run lsusb on Linux; the hardware ID should list RTL8811CU and the connection speed will show 433Mbps on 5.8GHz or 150Mbps on 2.4GHz.
