Broken Internet

Phone was playing up so we unplugged the internet. Phone worked but internet didn't. Tried internet in another phone plug then no phone or internet. Left with a 1980s trill phone that works in one socket and no internet.
Lovely  young man (I must be getting very old because he looked far too young) who found that all of the filter things you plug in had blown. He's never known all of them to go at the same time.
All new filters and everything back up and running but we were without internet for 2 days.
Took this photo so when I unplugged the modem I would have a chance of putting it back together right.
