It seems at this point that paying for Wi-Fi at hotels is about as outdated as a policy can get. In this day and age, internet is an essential component of our lives, and should be included in the room charge along with other amenities and services. Marriott, evidently, does not agree with this line of thinking.

Indeed, according to a report from Engadget, Marriott just paid $600,000 to resolve an FCC complaint about its Wi-Fi policies. The complaint arose at a Nashville Marriott location, where guests at a convention found that they were unable to set up wireless internet hotspots using their mobile devices. As it turns out, Marriott was deliberately blocking such third-party hotspots, allegedly in an attempt to force guests to pay for hotel Wi-Fi. The charge for the Wi-Fi service, Engadget reports, ran a ridiculous range from $250 to $1,000.

Unsurprisingly, the FCC got a complaint from one of the convention guests, who suspected that Marriott employees might be jamming customers’ mobile hotspots in an effort to increase their own profits. The FCC launched an investigation into this “unlawful use of Wi-Fi blocking technology,” and eventually fined Marriott $600,000 for the blockages.

Marriott says that it was not doing anything illegal, and that the Wi-Fi blocking system was in place to protect guests from so-called “rogue wireless hotspots.” Such hotspots could supposedly slow down the hotel’s exorbitantly expensive Wi-Fi network, or even make the network susceptible to attacks from hackers or cyber criminals. The FCC, though, has dismissed all of those claims, saying that “rogue” hotspots would never pose a real threat to customers.
