Yes it's quite slow but that could just as easily be because of intense use by people in the club. Each one of them has 2-3 devices and is sucking down files from the cloud in preparation for being on the plane. I don't believe blocking a few (relatively) outsiders is worth the hassle of having to manually authenticate. Oh by the way, if you like individual authentication, please encourage UA to use 802.1X _not_ little pieces of paper.
