El capitan slow to connect the network
Hi,
Since I updated, I noticed applications start very fast.
Unfortunately it seem that El Capitan is very slow to connect the network.
Consequently, Mail disconnect all my account, Safari show an error also iTunes, BOINC Manager is unable to load the tasks and stay in a Pause mode, etc ...
Any idea what could be the reason or how I may determine what's wrong ?
Thanks
iMac (27-inch Mid 2011), OS X El Capitan (10.11)
