I am faced with a modern ethical conundrum. My flat is very long and thin and, frustratingly, my wireless network does not extend from the office at the back to the lounge at the front. My dreams of sofa-surfing have been thwarted. However, my laptop does pick up my neighbour’s Wi-Fi connection. It’s called “belkin54g” after the brand of router he is using. A quick Google revealed the default passwords for this router, and a few security screens later, I’ve hacked into my neighbour’s Wi-Fi. I can now surf on the sofa while watching TV and drinking red wine. Bliss.

Of course, he doesn’t know this, which leaves the conundrum: Should I tell him his network is unprotected and risk losing my convenient living room Wi-Fi? Or should I continue to hijack his connection, risking discovery and a possible neighbourly feud?
