At home I have an ADSL modem, connected to a Linksys BEFSR11. We have 4 XP-Pro XP2 computers linked to that router via a D-Link DGS-1008T gigabit unmanaged switch.
I use my PC for VPN to office, kids use theirs for anything but that ;-)
Recently I discovered that our connection was dropped to smallband, because the kids had downloaded/played online/whatever... beyond our 10Gb 30-day limit.
Is there some piece of software that I can install on their PC that monitors their (daily) internet usage, and cuts them off (or puts them on some sort of smallband) when reaching their limits?
Alternative would be changing the unmanaged switch with a managed one, but these are way to expensive now...
