Because it surely doesn't forget a home network that I don't want it to every connect to again. I have 2 networks running in my house. One is a standard Airport Extreme password protected network. The other is run by a Linksys wireless router that connects my Crestron touchpanels to the control system. There is no password on this network because 1) it slows down the touchpanels and 2) there is really nothing to protect. The linksys router broadcasts an SSIS of "Crestron" and on occasion, both my and my wife's iPhone 4's will try and connect to this wireless network. It has no internet capability so I don't want to be connecting to it. I have used the "Forget This Network" button for this network, but it doesn't seem to work. It seems that once it finds this network again, it will keep going back to it. Any suggestions? Thanks.
