Solved How can I be connected to this ssid?

P

ifconfig shows I'm connected to ssid xfinitywifi

But that's somebody else's wifi. I don't have a password for it, and it's not in my wpa_supplicant.conf
 
It's Comcast hotspot. How do you connect to wireless network? Are you using a third-party program from the Ports Collection to manage your wireless connection (*),
or merely through basic wpa_supplicant.conf(5) configuration?

[EDIT]
(*) Some kind of check/uncheck/remember autoconnection setting in the GUI
 
A wifi access point can be configured to be "open", and not require a password to connect to it. Your wpa_supplicant.conf file probably has something in it that allows connecting to such a network automatically (no matter what the ssid is) if it can't connect to any other network.

No, it's a stock setup mostly. I use a window manager so there's no gui.

My wpa is pretty minimal:

Code: 
ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1

network={
ssid="my_ssid"
scan_ssid=0
psk="my_ssid_password"
priority=5
}
network={
        priority=0
        key_mgmt=NONE
}
 
It's that second "network" block that's causing what you are seeing - if it can't connect to network "my_ssid" for any reason (or gets disconnected temporarily), it will automatically try the second network block, which is a "any ssid that doesn't require a password" network.
 
Outstanding, this appears to be resolved. Deleting the second entry is the solution.

Thanks to both of you for your help.

I'm curious about this; on 16.0-CURRENT a few days ago I could have a wpa_supplicant with no mention of a key_mgmt=NONE entry, and still get auto-connected to a nearby open xfinitywifi AP.
Code: 
ee '/etc/wpa_supplicant.conf'
Code: 
network={
  ssid="Main (5GHz)"
  psk=x
  key_mgmt=WPA-PSK
  priority=4
}

network={
  ssid="Hotspot1"
  psk=x
  key_mgmt=WPA-PSK
  priority=3
}

network={
  ssid="Hotspot2"
  psk=x
  key_mgmt=WPA-PSK
  priority=2
}

# End
psk=x changed to encrypted keys from wpa_passphrase. wpa_supplicant on htop showed it using -c /etc/wpa_supplicant.conf (on the right file seemingly), but I don't know how it still can connect to xfinitywifi (it'd auto-connect to it if I broke the psk for Main) even with all priority lowered so Hotspot2 was 0 and Main 2.

I've had it happen 14.3-15.1 RELs and STABLEs too (both iwlwifi; back then I had AC9560, and 16.0 AX210)
