This device is the only device I log into this account with.
I have device sync off as well.
The only way I can change the settings for wireless networks that I don't want my device to connect to (that I haven't connected to yet) is this interface.
No matter how many time I un check that damn box, even with synchronize accounts off, it always stays checked. The only router that should have that option checked at ANY point is the one that I am currently connected to. All of those others are my neighbors routers.
