Thanks for A2A.
I can answer most of your queries but not all.
First , there is no limit on usage, i.e. terabytes per month is fine for us 😉
Websites under the category of porn, games, P2P, advertisement (till now i have encountered with these only, will update in future) are blocked, but some great personality once said ” where there is will, there is a way” so same applies here 😉
And students are provided with high speed wifi routers in their wing, but no LAN cables separately in their rooms.
And for maximum download speed , I once left all my stuffs and tried to discover this, but once the download started, speed kept on increasing @ some MBPS per second , and before reaching any terminal speed my download completed ( I am not a heavy downloader ) and maximum it reached was around 38 MBPS.
