Buongiorno, vorrei una vostra opinione circa un piccolo problema che riscontro oramai da tempo sul mio iMac (come da oggetto).
a casa ho una rete lan da circa 16-17 punti rete (rj45), fatta da me quando la stavo costruendo. Veniamo al dunque, quando vado a collegare un cavo ethernet sul Mac, su preferenze rete, la connessione va e viene, ovvero, vedo la connessione ethernet che si alterna in verde-connesso-disconnesso. Fino ad ora non ci avevo dato importanza, perché avendo anche un apple watch, preferivo la connessione wi-fi, in modo da sbloccare il mac con l'orologio, ma questa mattina, visto che non avevo nulla da fare, ho cercato di risolvere il problema. Escludo che sia una coppia di fili accoppiata male sul frutto di rete, perché lo stesso cavo se ci collego il macbook pro o lo stesso iMac, usando la porta thunderbolt, funziona correttamente. Quindi mi chiedo se possa essere un problema di natura HW o SW sulla porta di rete.
Qualcuno di voi ha lo stesso problema? o ne ha sentito parlare?
di sotto incollo il check di EtreCheck.
Grazie anticipatamente
