So every so often my Nexus decides not to connect to the Internet - even when it clearly has some bars up. Chrome says "Unable to connect to the Internet" and gives me the error Error 106 (net::ERR_INTERNET_DISCONNECTED). I go to Settings and Wi-Fi and Mobile Data Enabled are both on, so that's not it. I run Lookout Mobile Security and JuiceDefender, and I wouldn't be surprised if one of them is causing it - but how do I tell WHICH one, and is there any way to fix it without getting rid of those programs?
