The setup is an AT&T broadband connection with a modem-router that provides both phone and internet. Also, I presume, a LAN since there are four ethernet outputs from the device and WiFi is also available.

I know I can crawl around back and pull the ethernet cable but that isn't very convenient and might lead to malfunction of the cable plug or the ethernet port from over use. I want to be able to not be connected most of the time but (hopefully) have something as easy as closing a switch when I need to get online.

Needing to provide a password, as though using a dial-up modem, any time I want to connect is quite acceptable as long as my computer is truly not accessible to the network once I sign off. If this can be done purely with software, that might be ok if very reliable (very hard to hack).

Assuming you are talking about connection via ethernet cable, I know of something you can do that involves the clicking of a couple buttons.

 

1) Go to Device Manager

2) Open the Network Adapters Tab

3) Right click on the component you want to temporarily disable (most likely has ethernet in it)

4) Click Disable and Yes

 

This should work for temporarily turning off your Ethernet.

If you are asking for WiFi, on Windows 8 and 10 you can easily switch WiFi on and off, and also all wireless connections with Flight Mode.

 

It's possible for older versions of Windows too.

Personaly, if its just the WiFi you want to disconnect then i wrote a small batch file that will do it for you.

paste this in to notepad and save as WiFiConnector.bat

Then right click and run as admin to either Y for Yes=Disconnect or N for No to Renew IP.

@echo off
title WiFi Connector-Disconnector
choice /c yn /m "Would you like to disconnect the WiFi?: "
if %errorlevel% equ 1 ipconfig /release && goto end
if %errorlevel% equ 2 ipconfig /renew
:end
exit
