That's not the main reason, but it certainly is one of the reasons. We are are now in an RV park in Morgan Hill, CA and the connection is simply to flaky to maintain a connection. We were just in a park in French Camp, CA and they said they had great WiFi, you just needed to come to the office to be able to use it (this is a very large park and would require you to drive to this location). The main reason is bad infrastructure and some of the many other issues are the hardware used, the software used and the people who set it up and those who are expected to support it.
