1) I am using the latest Airport Extreme with a MBair Haswell (supports 5GHz) and i get daily the following issue.....many times after sleep mode the wifi speed is slow as hell... the trick to close open the wifi doesnt change anything... changing also connection from 5Ghz to 2.4Ghz doesnt do the trick. Only solution to get back full speed on my Wifi is to reboot the Macbook or to change wifi channels on wireless option of Airport Utility. BT is always turned off. 2) Another issue is that sometimes the search bar on safari stops working...? Freezes and stops. It happens only on Mac.... no issues with iphone 6's wifi all these months... maybe the signal drops sometimes but no speed issues there. Whats going on?... how many updates do they need to fix those issues? Apple tells us that we should wait more months until El Capitan... i am totally disappointed on them. ps1 - also airdrop functionality is another joke.... takes ages to find my iphone and most of the times needs mac reboot to get it working. ps2 - dont suggest me to do a clean install. I have done it twice since yosemite.
