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
  SessionLength in object /fi/w1/wpa_supplicant1/Interfaces/0
wpa_supplicant[1555]: wlp10s0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD
wpa_supplicant[1555]: wlp10s0: SME: Trying to authenticate with
  a0:##:##:##:##:0a (SSID='WiFiNetwork' freq=2462 MHz)
wpa_supplicant[1555]: wlp10s0: Trying to associate with a0:##:##:##:##:0a
  (SSID='MyNetwork' freq=2462 MHz)
wpa_supplicant[1555]: wlp10s0: Associated with a0:##:##:##:##:0a
wpa_supplicant[1555]: wlp10s0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0
wpa_supplicant[1555]: wlp10s0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE
  type=COUNTRY alpha2=CA
wpa_supplicant[1555]: wlp10s0: WPA: Key negotiation completed with
  a0:##:##:##:##:0a [PTK=CCMP GTK=CCMP]
wpa_supplicant[1555]: wlp10s0: CTRL-EVENT-CONNECTED - Connection to
  a0:##:##:##:##:0a completed [id=0 id_str=]

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?
