i am using windows 8 64 bit, and using MTS Mblaze Ultra (zte ac2791), internet is connected through dial up (Using model named 'USB Modem FFFE'),
so its always get connected as wished, but sometimes even its connected and in network inspector softwares also show data up and coming, but still there is no internet, DNS Resloving not works and ping not works etc.
and when i uninstall model driver and restart pc and then internet work again, if uninstall some software it work again (not a particular software), i facing very strange problem,
can someone help me how to debug or solve this wired problem? i have checked windows events & logs there is not strange logs, and i am tring hard on it since many days.
and i can say that problem is exits withing windows 8 64 bit,
EDIT: is there any tool and can directly interact with modem and get internet from it and make virtual nic if possible,
