I’m upstairs in Mr Donut on Showa-dori in Akihabara in Tokyo, using a free wireless LAN provided by CyberSPOT, a nearby shop. The first time you browse, you get an advert for the shop. After that, all data passes through perfectly. Excellent stuff, and exactly the way it should be. Unfortunately, there’s no signal downstairs, and upstairs is the smoking section, so I’m trading my lungs for internet access.
