Personal wifi networks, or “hot spots,” are an important way that consumers connect to the Internet. Willful or malicious interference with Wi-Fi hot spots is illegal. Wi-Fi blocking violates Section 333 of the Communications Act, as amended.1 The Enforcement Bureau has seen a disturbing trend inwhich hotels and other commercial establishments block wireless consumers from using their own personal Wi-Fi hot spots on the commercial establishment’s premises. As a result, the Bureau is protecting consumers by aggressively investigating and acting against such unlawfulintentional interference.
