WiFi Speed Spray.

OMG! It really WORKED!

Do you live in a polluted environment such as Los Angeles? If so, you’ve probably experienced the heartbreak of data transfer slow-down. WiFi Speed Spray™ can overcome the effects of pollution, increase fidelity, and provide you with the fastest wireless data transfer possible. Approved by the FCC, and 802.11b compliant! Compatible with Windows and most versions of Linux.

It’s a scientific fact. Radio waves become sluggish under a variety of common environmental conditions. Besides air pollution, radio waves slow down in noisy environments, at night, and in "high emission" areas such as computer rooms, offices that use fluorescent lighting, and even in the kitchen (those pesky microwave ovens are to blame!).

WiFi Speed Spray™ is designed to eliminate these harsh conditions selectively. Only the radio wave path is affected. There are no side-effects*.
