<human>: Could you distill the essence of the text into 1-3 sentences?

Hello everyone!

We have a 50 GB / month 10.0 speed ADSL2+ connection plan with the worst service provider possible (Telstra. Yes all the Australians just groaned). My problem is that I woke up, 12 days into the cycle and my internet speed was reduced to a cringing speed that couldn't even read e-mails. Add the fact I go to University and rely on an internet connection to access lecture notes and materials - and we have a serious problem.

The root of the problem is my sister. She is intellectually disabled and uses the internet as a source of entertainment, but has no concept of download limits or rationing. Hence she treats it like tap water - consume consume consume!

Now - my parents foot the bill of this internet service. They can be considered to be complete and utter dinosaurs and probably don't even know what the word 'bandwidth' means. In a normal scenario, I could just change internet plans and companies - but my parents are apathetic to the whole process and I won't succeed. I could monitor my sister's internet use and instigate 'time out' sessions for her, but as I travel to University everyday, this is unenforceable.

Please reddit. Help me. I am borrowing a friend's internet connection just to send this plea of help.

To finish off, I will add that my parents are not unreasonable. Living with a disabled sister is challenging, and finding ways to amuse her can be difficult and we are fortunate enough to have one readily able. I believe if I could get a speed limiter on my internet connection this could work, so long as my sister could still view YouTube videos at a decent speed, but as I'm no computer techie I would like to be walked through this (pretty please??)

Help me reddit, you're my only hope!
<bot>: Does anyone know anything about Internet Speed Limiters? Do they work and can you steer me through one? If not - read the article and tell me if there is anything I can do to limit internet download (caps etc)
