Hi, I have been using a K3772 dongle for some time, but recently got a new laptop. The usual page appears when I put in the dongle, and it appears to connect, but all that comes up is a request from Vodafone to add more funds. I have done this and there is plenty of credit - but it still will not access the internet. Help please! I need this for travelling around the country where there is no wifi access. Tony
