Are your students/pupils browsing all kinds of sites during the computer lab class? You do not need to switch off the network, there is a smarter way.
In a now previous life, when I had to deal with a university’s network (while also teaching there), one of the things I ruled were the web proxies. And Squid’s time ACLs are an excellent way to control what students can do in a computer lab.
