BT mobile broadband dropping signal just as it connects
I've been using BT mobile broadband for about a year and a half and have, for some reason, just started having problems in the last couple of days.
As i try to connect (through the BT connection manager) there's a solid blue light (indicating 3G signal) right up until the 'connecting to network' stage. (I'm using the dongle in areas which I know from previous use have good signal and 3G coverage). At the exact point of connection the solid blue light disappears and is replaced by a flashing one - the connection manager says the connection is made but it's clearly not as no pages will load. As soon as I disconnect the solid blue light returns.
Is anybody else having similar issues? As far as I can tell nothing has changed in terms of service or computer set up. I really don't want to go through the rigmarole of a call to the customer support line so any help would be much appreciated.
