hidden network on raspberry pi fix

thought i could just ssh into it.
thought maybe i just forgot what i called the pi.
nmapped but couldnt find it. thought maybe i suck at using nmap.
logged into the router. still didn't see the pi.
ugh I really didn't want to have to get up and grab that hdmi cable.
turns out the network wasn't showing up.
makes sense, since i set the new router to hidden.
used raspi-config to add it back.
tried rebooting still wasn't showing up.

THE FIX

• cd to /etc/wpa_supplicant/wpa_supplicant.conf
• add scan_ssid=1

network={
       ssid="your SSID"
       scan_ssid=1
       psk=your PSK 
}

then reboot
