Limit download amount

Level 2

Hi there,


Even though I have unlimited broadband, I would like to know if I can put a limit on the amount of gig someone can use. I noticed that in the last 30 days we have used 300 odd gig and there is one person in the house that downloads alot and our internet has started to cut in an out alot more now.


If I am able to, can I have the instructions please. I have a Archer VR1600v
