If you bring a personal Wi-Fi hotspot with you on your travels, then some hotels may have already tried to block your connection. Some hotels aren't happy with you paying only for its rooms, and want you to pay for Wi-Fi, too.
Unfortunately for hotels, many travelers have opted to bring Internet-connected Wi-Fi hotspots with them. The hotels' response? Jam the Wi-Fi hotspots.
If a hotel can't "beat 'em," it seems, some chains have opted to "jam 'em."
This move was so shady that even the Federal Communications Commission is getting involved.
The FCC warned Marriott that blocking its guests' Wi-Fi hotspots wasn't a very ethical thing to do in this statement:
The Enforcement Bureau has seen a disturbing trend in which 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 unlawful intentional interference.
Marriott claims that the hotspots were disabled for security reasons.
