Well, this is curious. The Wi-Fi icon was white this morning. Three bars, but white. No data was doing what it should have been doing (i.e., apps couldn't connect, browser couldn't load a webpage). Here is the curious part: My Nexus 7, sitting the exact same location, and connected to the very same network, had a nice, strong, four blue bars wi-fi signal. I googled this (on the Nexus 7, obviously) and the problem appears to be not entirely uncommon -- but there also didn't appear to be a universally acknowledged solution. In my case, it resolved on its own, so it's a no-harm, no-foul sort of thing. But I am a bit worried. I've come to rely rather heavily on Wi-fi at home (as the 4G isn't always reliable) and I'm not at all happy about the RAZR's Wi-Fi going white (and useless) for no obvious reason. Anyone got any ideas on the cause or solution?
