With my previous HTC myTouch 4g phone I never experienced any form of wifi connection or data problem, but with my new Nexus 4, the apps often report "unable to connect to network," and when I download apps I frequently get "Invalid App Package" errors, I've had to retry downloads as many as five times to get a good download. Nothing (so far as I know) has changed with respect to my Wi-Fi setup. I'm operating the phone in the same room with the router.
