Wi-fi: "Device not managed" in Network Manager

[ndp]

Hi all—my PBP has been offline for most of its life, but recently I've started seeing "Device not managed" in the Network Manager menu where my wifi connections should be. I understand this to mean that Network Manager thinks some other system is managing the wifi interface, but I haven't been able to find out what.

I've run through the steps in the wiki under https://wiki.pine64.org/index.php?title=...iFi_issues but come up short—nothing changes. Advice I've seen on other forums hasn't helped either.

Here's my /etc/network/interfaces:

Code:

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

(/etc/network/interfaces.d is empty.)

Here's /etc/NetworkManager/NetworkManager.conf:

Code:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[device]
wifi.scan-rand-mac-address=no

Do you know where I can start looking to troubleshoot this? I see some wifi-related messages in `dmesg` but I'm not enough of a Linux networking guru to make sense of them.

Sadly, I do not have `ifconfig` or `iwconfig` or any such tools available, since they don't come in the stock install and I can't get online to install them.


(Last, semi-related thing: could someone let me know so I can edit the wiki to clarify which state of the wifi privacy switch is which? It says "2 blinks = enabled, 3 blinks = disabled", but I don't know if "enabled" means "the privacy switch is enabled" or "the wifi adapter is enabled". I've had to trial and error it.)
