Hi, I am trying to setup a Vigor 2920 router for in a holiday cottage, My broadband has a download limit of 20mb per month, and wish to limit the usage on a weekly basis, so that Week 1 users do not use all 20mb leaving none for other users later in the month. As I understand, this is slightly different to bandwidth limits - I do not wish to limit how fast users can download, but how much they can download.
