No routers allowed?

Looks like the wifi threads are going to go the way of the 50 Amp electrical threads and contain a whole bunch of wrong information. The fact of the matter is there are only twelve frequencies that can be used for standard wifi. Within those twelve frequencies, only three are separated enough to be completely interference free from the others (i.e channel 4 and channel 5 do overlap). Everyone's private router will send out a signal that will overlap and interfere with other people's wifi systems. The greater the interference, the more likely the signal will actually bump off a connection. It appears the park is trying to solve an interference problem, and it is equally clear that people aren't going to like the solution. Therefore, it appears the park has a lose/lose situation. They get to choose between having wifi problems or upsetting people who think they are being mistreated because they don't understand the working of a wifi network. They should consider dropping the rule, because it is also obvious no one is going to follow it, so they will still have the problem and a thread like this to further damage their business. Sometimes it is just easier to let the monkeys run the zoo and live with the results.
