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."
