I am trying to figure out how to use the internal modem of the Modem to connect to the internet. On the other hand I have also attempted to install a Huawei E220 modem, but I keep on getting a message it cannot install, it does not find some VBA software and the process stops - With another USB stick modem (K3565), but this process also stops halfway with message that the installation was interupted - I need some urgent assistance
