Is this the wittiest misuse of Wi-Fi yet conceived? A man in my locality town decided to use wireless access points to insult one of his neighbours with unpleasantly-named SSIDs.

SSIDs, or service set identifiers, are the publically broadcast names given to access points, which in the overwhelming majority of cases end up being something like ‘TalkTalk xyz' or ‘Netgear very fast router'. Some even hide them under the misconceived belief that this makes them more secure (it doesn't).

This particular gentleman's choice was, allegedly, more like ‘Mr X is a tosser' and ‘I never fancied his wife anyway', cycling through a variety of such names in successive nights. Being sued for that misdemeanour would surely make legal history, but would it be libel (i.e transcribed) or slander (spoken)?

On a more serious note, Wi-Fi security outfit AirTight, <a href="http://www.airtightnetworks.com/home/resources/knowledge-center/financial-districts-scanning-report.html"target="_blank"> has published a new survey on wireless security </a> or the lack of it. Incredibly, WEP encryption is still popular on among businesses in six financial districts in the US and one in the UK. A quarter of the APs looked at were open.

So WPA - or some Wi-Fi security box from AirTight - could save them from imminent disaster. But could it save the chap down the road from himself?
