The relevant text of the FCC enforcement advisory you just linked to is:<p>&quot;No hotel, convention center, or other commercial establishment or the network operator providing services at such establishments may intentionally block or disrupt 
personal Wi-Fi hot spots on such premises, including as part of an effort to force consumers to purchase access to the property owner&#x27;s Wi-Fi network.  Such action is illegal and violations could lead to the assessment of substantial monetary penalties.&quot;
