I've noticed an issue with my i7 SP3 recently. When I turn on (wake up, whatever...) the unit after it sits closed and idle for a while, maybe a few hours or more, Metro apps cannot connect to the internet. I've noticed this especially with IE, the Store, and the weather app. They don't just hang, they actually show a big message that there is no connection. However, if I go into desktop apps, I can connect just fine. Last night, I toggled my wifi off and on, and all was well again. Is this common?
