Here’s a write-up on (D-Link’s USB Wi‑Fi adapter) under Linux .

Linux support depends heavily on the revision because each chip requires a different driver.

However, the landscape has improved significantly with the advent of Revision C and the maturation of the Linux kernel. Modern Linux distributions running kernel versions 5.11 and newer often include drivers for the RTL8821CU chipset out of the box. This integration represents a significant victory for the open-source community, as the support has moved from unstable, out-of-tree drivers to stable, mainlined code. The experience of using the DWA-171 has thus shifted from a command-line troubleshooting exercise to a plug-and-play experience for most modern distributions. This transition highlights the success of hardware manufacturers increasingly cooperating with the open-source community and the dedication of kernel developers who reverse-engineer and refine these drivers.

Typical output:

Verify that the DWA-171 is connected to your network:
