Gmail IMAP problem

Hey,

Every time my retina 2,3 is coming back after a deep sleep my Mail program can't reconnect to my Gmail account. shutting the program down and open it again, does solve the problem for that time.

I'm pretty sure many use Gmail and Mail with ML and it works fine after deep sleep... no?

I've tried to reset my account. tried open the account on the different user. change the internet settings and what not, but the problem always comes back.
I even had over 3 hours in total of Apple Care phone calls that led to the conclusion that they have no idea what can cause the problem...

Any one else had the problem? or still have?
or even better, does anyone have an idea how to solve it?
