Interesting. I had the hardest time getting wpa_supplicant working on a new Debian install last weekend, and eventually gave up and switched to iwd, which was new to me, but worked immediately

Checking now, I have wpa_supplicant 2.10, so I wonder how much of my problem was due to that.

iwd's been great so far - I'm no expert so maybe there are technical advantages, but I don't see any reason to go back to wpa_supplicant.
