This is a creepy story. The FBI wanted access to a hotel guest's room without a warrant. So agents broke his Internet connection, and then posed as Internet technicians to gain access to his hotel room without a warrant.
From the motion to suppress:
The next time you call for assistance because the internet
service in your home is not working, the "technician" who comes
to your door may actually be an undercover government agent.
He will have secretly disconnected the service, knowing that
you will naturally call for help and -- when he shows up at
your door, impersonating a technician -- let him in. He will
walk through each room of your house, claiming to diagnose the
problem. Actually, he will be videotaping everything (and
everyone) inside. He will have no reason to suspect you have
broken the law, much less probable cause to obtain a search
warrant. But that makes no difference, because by letting him
in, you will have "consented" to an intrusive search of your
home.
Basically, the agents snooped around the hotel room, and gathered evidence that they submitted to a magistrate to get a warrant. Of course, they never told the judge that they had engineered the whole outage and planted the fake technicians. (more)
