A very WiFi Christmas

The last time I brought my laptop to my mother’s house I was hoping I would be able to ‘borrow’ some Wifi. Sadly, there was no WiFi to be had, and during subsequent visits I left the computer at home. However, I knew that there was WiFi available this time because my mother’s computer (I gave her my old iMac) helpfully joined one of her neighbor’s networks.

Therefore, I find myself using my MacBook and suckling from the sweet, sweet teat of free WiFi (well, it is free to me). Futhermore, I was shocked to find not only one WiFi network but several (see the picture to the right). What’s up with that?
