i need a driver but can't find it anywhere

"the only drivers i could find for him was downloaders that would download and install the driver but how if he has no internet omg"

You download on another computer, extract what you need, coyp it and install manually on the laptop that needs it.

Edit : in the meantime you can try to burn a live dvd of some linux like ubuntu, not sure if it will give him temporary access to the net for his mails or whatever, but you can always try. You can also just contact huawei and ask them. At the very worse it is possible to write your own driver, but its a pain, did it once, won't do it again, there are instructions for that on the net, but i doubt it will come to that.

Why hire a driver when you can hire an ACE pilot?

It works for me, without redirections or popups. Here's the direct link to the driver (still check it for malware, of course!):

And stay away from driver downloaders/managers/boosters!
