Ciao a tutti,
prima ho riscontrato nuovamente un problema abbastanza fastidioso:
mentre navighiamo normalmente ad un certo punto la connessione si interrompe.
Il router continua a funzionare, ma la connessione internet è andata offline (e non si ripiglia fino a quando non sono io a staccare e riattaccare il cavo di rete che arriva dall'ONT).
Vado a veder nel registro del router e trovo questo:

Guardacaso l'IP di provenienza è cinese, un po' come tutte le altre volte che capita. Stavolta ci han provato con la VPN.
Solo che non capisco come mai ad un certo punto la connessione internet cade, può essere TIM che blocca qualcosa?
Perché il router continua ad operare normalmente, sembra solo che la sessione PPoE venga interrotta.
Secondo voi?
EDIT: aggiungo che la cosa oggi è successa quando pure su downdetector c'è stato il picco di segnalazioni per TIM (so che conta poco, però...)
