This is my first question on this forum. I looked through other threads on this forum and couldn't find anything similar. Here's my situation. I have an iPhone 4 and I live in an apartment building. One of my neighbors has an Airport or a Time Capsule. I have WiFi through my own router. Periodically, my phone asks me if I want to connect to my neighbors Airport. (I guess my first question should have been how do I get it to stop asking me this). Anyway, I normally just hit cancel, but one day I accidentally hit "join". Now my iPhone prefers to connect to the airport over my router. The result is that the airport (which I don't have any security access to) blocks my own WiFi. The result is that I cannot use any data on my phone in my apartment without manually going to settings every time I want to use data and selecting my network. I've tried for the past few days to find some way to disable this. I know how to "forget a network" on the iphone, but the airport connection is in a separate area and I can't seem to figure out how to block this. If anyone has any ideas, I'd appreciate it.
