I have an AT&T Radiant Android phone. If I have Wi-Fi turned on, every time it detects, a Wi-Fi signal, it makes a sound. The same sound it makes if I get a text message. They both seem to use the same sound set by "Default notification" in the settings. I don't want to be notified if a Wi-Fi signal is available. I like to take walks, and I don't like hearing that sound every time I pass a building. But I do like to use Wi-Fi when I'm bars or restaurants or even my own home. It's a pain to keep turning Wi-Fi on and off. But I do want to get the notification when I receive a text message. Is there a way to separate the two?
