I finally bought another Mac, after 6 years of PC usage. Left PC behind because of all the headaches it's software caused. It's the current base model 15" macbook pro. After 1 day of use, I'm having a little bit of connectivity issues. After the computer wakes up from having the lid closed, Safari tells me it can't connect to the internet. Up top, my wifi signal shows it's connected to my network. I start diagnostics, but before it even finishes it connects back, and restores to full functionality. I know the issue is not on my side, never had any issues with wifi, even on those 'terrible' PC's I have Yosemite 10.10.5 installed. Any help would be appreciated.
