Constantly dropping internet on El Capitan? I have a brand new 2015 mac, el capitan 10.11.4. The wifi constantly drops. I have re-installed a fresh el capitan, reset SMC, created new wifi profile/location with google dns, safeboot, updated router firmware, and update router channel. None of these things have fixed the constant dropping. The dropping mostly happens when I open multiple tabs or download multiple things at once. Any recommendations? How can I analyze the dropped connection report?
This fixed it for me:


System Preferences &rarr; Energy Saver &rarr; Battery Power: Uncheck “wake for network access”
System Preferences &rarr; Network &rarr; Advance &rarr; TCP/IP: Configure IPv6 – select “Link-Local only”


Found the above fix in the comments of this article: http://osxdaily.com/2015/10/16/fix-wi-fi-problems-mac-os-x-el-capitan/
