They're probably trying to get away with fewer hotspots and a smaller pipe and thus lower cost. It's just like most gyms and pools you see in hotels. They're put there to add a checkmark to travelocity/similar for marketing purposes. Nobody asks if a hotel has good wireless, only if they have it. Make them move you to a different room, get it for free and if you still can't get connected and actually need it for work, push them to give you a reduced room rate. For a business traveller, internet is necessary.
