A number of readers sent in stories about Net radio going dark for a day. Not all of it, but according to the Globe and Mail at least 45 stations representing thousands of channels. The stations are protesting a ruling establishing royalty rates that will put most of them out of business on July 15. "The ruling... is expected to cost large webcasters such as Yahoo and Real Networks millions of dollars, drive smaller websites like Pandora.com and Live365.com out of business and leave a large chunk of the 72 million Net radio listeners in the dark." SaveNetRadio has a page where US residents can locate their senators and representatives to call them today.

ElvaWSJ writes "Wi-Fi was supposed to reduce complications, not create new ones. But in many offices Wi-Fi has been a headache. Like all radio signals, Wi-Fi is subject to interference. Its low power — less than even a typical cellphone — means that walls and cabinets can significantly reduce signal strength. Wi-Fi also creates networks that are more open than wired ones, raising security issues. And Wi-Fi has caused problems for virtual private networks. Some VPNs require a lot of processing power. If a wireless access point — at home, at the office, or on the road — isn't robust enough, a user often gets bumped off the connection."
