I've had my Nexus One since release (probably like most people here) and I've noticed that on occasion the 3g to wifi handoff in a wifi area sometimes doesn't happen.....for example, when I come home where I have an unsecured wifi connection, the phone won't automatically switch. When I go into the wifi settings, it detects the connection but says 'connection unsuccessful'. When I click to connect to my wifi, it does so immediately. And, when in this 'connection unsuccessful' mode, no matter where I go (work, home, airport), it will not automatically switch to the available wifi unless I go into the settings. I don't remember it happening the first couple of days with the phone, but maybe I just wasn't paying attention. Anyone else having this issue? Anyone have an answer? Overall, not that big a deal, I just would rather it be seemless ALL the time.
