A Miami Beach reader noted my Florida links yesterday, and wondered why that city's $5m IBM network isn't live: The network contracted was awarded in 2006, completed 6 months ago, and the reader can get great signal strength. But no Internet feed. Anyone in Miami Beach know?
The brilliant xkcd comic takes it to the next step: Wireless zero config? Try overzealous wireless config.
Microwave oven may have disrupted reader's Wi-Fi: Rob Pegoraro over at the Washington Post notes that a friend of his discovered through the process of elimination that his microwave oven was acting as a big interferer with his Wi-Fi network. The oven in question eventually started smoking and burned itself out, and its removal resulted in the network working fine. All microwave ovens produce low-intensity 2.4 GHz radio waves when in use; they don't leak the high-intensity signals that are reflected to agitate water molecules and heat food. But Wi-Fi uses such low signal strength to encode data that microwave ovens can be enough of an interferer to slow networks down. They won't cook you though, unless you crawl inside and close the door.
