Gestisco un piccolo ufficio con 7 mac e 1 PC. Un iMac 2010 in aprticular ha problemi di connettività Internet in corso in cui dice che è connesso (tramite Network Diagnostics) ma si spegne di nuovo in modo intermittente (tutti gli altri computer mantengono la connettività di rete senza problemi). Il computer è collegato via ethernet a 10ft dal router. A volte ho il login in modalità wireless e il problema scompare quindi torna di nuovo
- Qual è il miglior flusso di lavoro da eseguire per isolare questo fastidioso problema? Non sono in questo posto tutto il giorno e si verifica quando non sono di solito lì. La mia preoccupazione è che potrebbe essere la scheda Ethernet che potrebbe essere difficile da isolare.
- Ci sono test particolari che posso eseguire per isolare dove lungo il computer al percorso di rete, il problema si sta verificando?
- Devo prima cambiare il cavo Ethernet? Credo di averlo già fatto questa macchina ...
- La diagnostica di rete è affidabile?
- Dovrei solo provare a eseguire il ping di Google dalla riga di comando?
- Dovrei guardare il Pannello Preferenze di sistema e cerca l'IP autogestito o cerca un Lease IP dal router?
Grazie
Aggiorna Ecco alcune voci di console.log. Il problema di connettività dell'app store si è verificato quando stavo cercando di scaricare Mountain Lion per aggiornare la macchina ed è la prova del problema ricorrente. La connettività internet scompare. Ero lì oggi quando è successo ma era così intermittente
