I have connection problems. I can hear you intermittently.
'Connessione' = kon-nes-SYO-neh. Four syllables; stress the third. 'Tratti' = TRAT-ti.
Use this when your internet is unstable and audio/video is cutting in and out. It quickly explains the situation and sets expectations for the rest of the call.
'A tratti' (in patches/intermittently) is a very useful Italian adverbial phrase for describing something that works only sporadically. It applies to audio, video, signals and many other contexts.
La connessione è instabile. Spengo il video.
The connection is unstable. I am turning off my video.
Proactive solution that preserves audio quality when bandwidth is low
Il segnale è debole. Potete mandarmi le slide dopo?
The signal is weak. Can you send me the slides afterwards?
Requests compensating materials for what you might miss
Vi sento a scatti.
I can hear you in bursts.
'A scatti' is another Italian phrase for choppy or intermittent audio
Internet quality varies enormously across Italy. Urban centres like Milan and Rome have excellent fibre connectivity, but rural areas ('zone rurali') and small towns can still suffer from poor broadband. This geographical disparity is a recognised challenge for Italian remote workers.
