INSTALLATION:  always use https://www.raspberrypi.com/software/
“Install Raspberry Pi OS using Raspberry Pi Imager”  – never just “click-drag” and image, that does NOT work
===========================
default ip 192.168.123.20 username/password: ubnt/ubnt
1) set new IP number under “Network”

6) rename radio
raspberry pi computer:
user:  pi
pass:  raspberry   ??me??57!
@reboot ( sleep 15 ; bash -vx /home/pi/iptablesSetup.bsh ) > /home/pi/iptablesSetup.bsh.log 2>&1
- since the current modem does not allow for remote access, just grab pages for display (cheap shot)
