go read these next besties, they're literally the whole friend group:

✨ BUGS ✨

okay so here's the tea, and it's a lil sad 😭 —

The rtwn_usb driver does not support any of the 802.11ac capabilities offered by the adapters. Additional work is required in ieee80211(9) before those features can be supported.

so like… yes bestie, you bought an AC adapter. no, you're not getting AC. the hardware's ready, the stack isn't. it's giving "dressed up with nowhere to go" 💀 don't @ me, @ ieee80211(9).

and that's the whole page, bestie 💖 this one came from Debian, dated November 10, 2024 — so if you're quoting her, cite her right. mwah 💋 ✨🎀
