It is on my home network. My administrator says I hog the internet. I cannot even update programs

"It is on my home network." If it's your home network, presumably you are the administrator?
No, as we are 5 computers on a home network
Well, just talk to whoever is the Administrator.
As I said, he is not to be reasoned with. I do not want to go into his bad behaviour. As I cannot reason with him, I would like to get a solution myself
Pay for your own Internet access. He who pays the piper calls the tune. I don't think that you will get advice here about how to circumvent restrictions put in place by employers, schools, or parents.
I understand and thank you. We all pay for the internet together. But as you say, it is not the right place to discuss my personal stuff.
