Can anyone help with the following

1. I can't upgrade E1550 firware- it keeps saying cannot find data card even though the modem is plugged in.

2. Uploading problem - I always cannot upload files, especially when I want to send attachments via Outlook Web Access.

2. Broadband booster - saw someone plugged this into the Digi USB modem. Is there a different type of usb modem and where to get this booster. I've asked some shops in LY but nobody selling. Can this booster improve my upload problem?

Yes, I dc from the net b4 i try to install
