Ho OSX 10.9.2. Un giorno la mia connessione internet ha iniziato a bloccarsi durante il caricamento.
Nessun aggiornamento di sistema rilevato prima.
Quando ho provato a inviare il ping a http://stackoverflow.com/
ho ottenuto:

Tuttavia il ping su 8.8.8.8
funziona bene (perdita dello 0,2%)
Cosa ho fatto finora:
- riavvia MAC
- restart Router
- altro PC Windows 7 funziona bene
- hotspot creato con iPhone e dati cellulari usati - hanno le stesse perdite
Sembra che OSX abbia problemi con DNS.
Im nubby in OSX, per favore da dove devo iniziare a indagare sul problema?
[EDIT]
Le mie impostazioni DNS di seguito:
Grazie,
