Thanks! I already did that once, but tried again, and after a bit of a wait, and a restart of my network card, it all finally seems to be working again 🙂 Not sure what made it all fall over, or why the first reset didn't help. Maybe Virgin needed a bit of time to think about it? My thought is that perhaps there is a dodgy connection in the hub, which was disturbed when I moved it to reset, and the second reset nudged it back? Maybe I should glue it to the table in case it dislodges again!
Thanks again.
