I haven't even found somewhere they suggest reformat and re-install -- there isn't much out about this - but it is very strange. It just happened all of a sudden. The modem works ofr a terminal program I have, shows in devices and can be queried and shows to be working - HOWEVER when looked at as an internet connection it shows "X modem removed". I even uninstalled the modem and insrtalled an external I got and it came up the same way.
I would be interested in anyone who has seen this too.
