quello che mi fa rabbia e’ che dovrebbe essere linux friendly sto coso ma da quando ho il portatile (thinkpad T450) non ha mai funzionato… mah!

Ah aggiungo che molti mesi fa segnalai questo non-funzionamento con tanto di log al progetto ModemManager , ovviamente i fix latitano…

giocherellandoci un po ha funzionato ma , dopo un po di tempo e’ scomparso ancora e:

Sto riportando pari passo i vari problemi sul progetto ModemManager

Spero di venirne a capo ma inizio a sospettare che sia il firmware visto che il modem va in una sorta di crash e scompare.

P.S. di firmware nuovni non ne vedo :S

Ciao @JackDaniels premetto che non utilizzo tale scheda , hai dato un occhio qua se magari riesci a risolvere il problema : https://forums.linuxmint.com/viewtopic.php?t=262003` o qua https://cloudnull.io/2018/07/x1-carbon-wan-linux-heaven/ ? :slightly_smiling_face:

Ciao @edmondo :slight_smile:

Allora ho risolto , in pratica il problema era proprio il firmware. Ho dovuto seguire una guida per aggiornarlo all’ultima versione disponibile FIH7160_V1.2_WW_01.1644.00(era un binario MS , un inferno perche questo modem non e’ gestito da sierra ma da lenovo) e il problema si e’ risolto. Rimangono tutti quei warnings , spero che su freedesktop risolvano anche quelli (che non inficiano le prestazioni).

Che casino sono contento che hai risolto :slightly_smiling_face:
