"""
    TP-Link devices typically only allow one login at a time to the admin console.
    This script will count towards your one allowed login. Depending on how
    aggressively you configure this, you may not be able to access the
    admin console of your TP-Link device without first stopping the script.
    
    This scripts scans for devices by logging into the router admin page and returning all devices connected to WiFi.
    
    Usage:   tp-link-archer-d2.py -i YOUR_ROUTER_IP -p YOUR_ADMIN_PASSWORD
    Example: tp-link-archer-d2.py -i 10.0.0.2 -p password
    
    Works with: [TP-Link Archer D2](http://www.tp-link.co.za/products/details/cat-15_Archer-D2.html) Router.
