Grafana not loading wireless adapter (wlan0)

[kllngtme]

Grafana pulling from the wlan0 adapter is extremely useful. I can't get it to work after upgrading. I tried the older firmware again with the same results so I'm not sure what I really did. Kismet works as it should. I can use the scanner function using the onboard screen and Linux sees the wlan0 interface. I just don't see an option to use the wlan0 interface with grafana like I used to.

What does systemctl status wlanpi-grafana-scanner output?

If, likely, inactive, can you start it with sudo systemctl start wlanpi-grafana-scanner?

Then check the journal and share output journalctl -u wlanpi-grafana-scanner -b.

I guess I could try installing the os again...

wlanpi@wlanpi-864:~ $ systemctl status wlanpi-grafana-scanner
Unit wlanpi-grafana-scanner.service could not be found.

wlanpi@wlanpi-864:~ $ journalctl -u wlanpi-grafana-scanner -b

[sudo] password for wlanpi:

I know I tried installing the os again already. But it worked this time around. 3rd time's a charm.

That's really weird. Something worth noting so thanks for bringing it up.
