Wireless USB adapters
Radios that come up
on the first plug.

Drivers
Every adapter ships an open-source Linux driver — full source, build files and packaging, published on GitHub.
No binary-only kernel module to chase across kernel upgrades, and nothing to reverse-engineer to see what the adapter is doing on your machine.
