The Economist:

THE wireless network at Mayhem Manor spreads from the router in the workroom to the living area of the one-storey hillside dwelling, but not as far as the bedrooms. And that’s important.
Your correspondent has often been tempted to upgrade his WiFi router with the latest 802.11n technology–as much for the increased range as for the four-fold boost in speed. Being eight time-zones behind many of his colleagues, he often checks e-mail in the middle of the night. His trusty little Hewlett-Packard palmtop computer, with its Cisco wireless card, would slip easily under the pillow.
But he’s resisted boosting Mayhem Manor’s wireless signal for several reasons. First, while it would quicken transfers between computers in the house, the internet connection would be no faster. Its speed is governed by the pathetic dribble of a broadband connection that’s 15,000 feet from the nearest telephone exchange in the village below.
The other reason for not upgrading is that he would prefer his tweenage daughter to do all her web surfing, e-mailing, online gaming and social networking not from the privacy of a bedroom, but from a common area of the house where an adult is invariably present.
