T-Mobile home internet Arcadyan gateway hidden WiFi settings edit v1

arcadyan-wifi-v1.py

# This script is tested to work with T-Mobile home internet Arcadyan KVD21 gateway.
# Tested on Mac OS 13 Ventura with python 3.9.6.

# Purpose:
# Display current wifi information.
# Choose to exit with no changes or enable/disable 2.4 GHz and 5.0 GHz wifi networks.

# This script needs your Arcadyan administrator password to run, type it into this file below.

# Usage:
# Run from the command line:
# python3 arcadyan-wifi.py

from os import popen
from os import remove
from os import path # to get current user's trash directory
from subprocess import run
from pathlib import Path
import sys

# -------------------------------------------------------------
# ----- ATTENTION, PASSWORD NEEDED BELOW FOR GATEWAY ACCESS ---
# -------------------------------------------------------------

# Administrator password goes between quotes on next line 
admin_pass = "admin-password-here"

# These two files may be created by this script
