Answer below.I upgraded to the unstable DP just because I wanted to have my WiFi working again. Even Yosemite beta 10.10.4 wasn't working for me (which has brought back the old mDNSResponder) as it should. Nowhere near Mavericks' performance in terms of networking (which, btw, had the better name of all the three last major releases). With the DP, I have encountered no problems with networking so far.
Having my WiFi back is well worth the instability in other things.
Has anyone any odd experience with networking?
Wifi completely drops out randomly and won't come back until you toggle wifi off then on
I'll try and update to El Capitan when it launches, but seeing how none of Yosemite updates/versions fixed my connectivity issues (the ones described by Hackintosh) I'm not confident that they'll be fixed. And yes, downgrading back to Mavericks each time was a pain in the ass.
