> What is the range of possible values for this -D option, and why would you ever want to specify it in the netplan yaml instead of inferring it?
It would be best if wpa_supplicant selected the correct driver, but it seems it doesn't do a good job with this. It does support fallbacks, though, which seems like a reasonable default behavior for wpa_supplicant ("-Dnl80211,wext"), but sometimes different drivers have different behaviors/abilities, so explicitly choosing one is useful. I see two issues: - wpa_supplicant makes no attempt to automatically pick a working driver - netplan doesn't have a way to choose a driver if wpa_supplicant's default (nl80211) doesn't work -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814012 Title: netplan type wifis needs a device option To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1814012/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
