After some advice. We offer free unlimited wifi (adsl2+) No real system.. It was set up to be secure (where guests can't connect/see other guests connections etc... But apart from that no limitations. We now find that with netflix and other streaming apps etc that it only takes 2 people to be using it and it wipes out our connection. We are wanting to now impose some limits via a third party PNP system. Tonight for example some one is connected to vuze and downloading constantly and we can't even kick them off or block it. Basically we now need to limit usage and bandwidth, whether this is done using a voucher system or what not. Not keen on ongoing monthly fee's as prefer to pay for system outright and have control over it myself. the link in the post about freenet and terry no longer works. What do you use or are you happy to have people streaming?
