Fwd: How do I troubleshoot wireless network dropping?

Thank you for the suggestion. I checked when it started dropping and, not only
was there one instance of wpa_supplicant running, it was the same instance
(judging from its PID)

Another good suggestion. I've tried disabling it from ifconfig. The interfaces
use consistent device naming, so the names shouldn't be getting mixed up.
I've isolated, what I think are, the journal lines from when my connection
dropped today:
wpa_supplicant[1555]: wlp10s0: CTRL-EVENT-DISCONNECTED bssid=a0:##:##:##:##:0a
reason=4 locally_generated=1
wpa_supplicant[1555]: dbus: wpa_dbus_property_changed: no property

wpa_supplicant[1555]: wlp10s0: Associated with a0:##:##:##:##:0a

wpa_supplicant[1555]: wlp10s0: CTRL-EVENT-CONNECTED - Connection to

For the purposes of these log entries, "WiFiNetwork" is the SSID of my
network, but the log literally shows "MyNetwork" in the next line when
it's trying to associate. I have no idea what this network is and I
can't find it configured anywhere. So is it possible that someone's
trying to MAC-jack my laptop?
