"I pay for that internet access and that router is my equipment. Your work is your responsibility, I don't have to provide you with an internet connection to get your work done, that isn't my responsibility - you aren't my responsibility. How you get your work done is your responsibility - go to an internet cafe. go to a friends (OM) or work from a real office instead of home and as far as legal action is concerned, there is nothing you can do which forces me to provide you with internet connectivity: I can turn it on when I want to use it and turn it off when I don't or I can contact the service provider and cancel it altogether, I don't owe you anything. If you want to pursue legal action over me disconnecting the internet at our home, I invite you to do so, be my guest - either way it makes NO difference to me."
