i have the same problem, it started yesterday - can not figure it out - anyone with any ideas?

Hi,

Success. I have a ZTE usb prepaid modem + a post paid WiFi plan. Today my ZTE (used with my Netbook) returned the dreaded 770994186 error code. Clearly a common problem as a quick google delivered two pages. After trying ALL the suggestions I found on the web without any success I did find that you can do without the Vodafone software completely.

Solution: just plug in the stick, go to devices and printers, right click on the modem and click dial vodafone. Works perfectly for me without using the supplied software. In fact I have even disabled the autostart to be sure. I have repeatedly dialled and disengaged and it has worked perfectly every time.

Unless there is something unusual with my W7 setup, this should be a common solution for all.
