But if I need terminal to debug why 770 not going to net in first place..

So I downloaded deb package above with another device and put it in 770. Application manager says what packages missing, so I downloaded them too, but then Application manager says for them:
"Unable to install.
Incompatible package."
And not any hint why is incompatible.

EDIT: I checked my OS version 3.2006.49-2 from control panel, so it should be Maemo 2.2, Gregale (checked from wiki.maemo.org/Codenames). I also tested install packages from 2.0 and Mistral and even from Maemo 1.1 and 3.2 folder. All gives that "Incompatible package."

So my original question is not solved yet.
