Apple is asking developers to focus on Wi-Fi, Exchange accounts in Mail, and the Notification Center.

Just don't understand how working code in Mavericks never made it into Yosemite. Like Wifi worked in Mavericks, why isn't it working in Yosemite? Did they purposely break the code?

All these working sub systems, battery, graphics, etc...now having problems don't make any sense to me.

Someone like to explain?

It's not that simple. Yosemite has a lot of changes under the hood including iOS style wifi airdrop, iPhone hotspot configure, continuity, etc. who knows the exact path a wifi bug can take. It's a bug.
