My current approach would be to use the Research skill and the Computer Operation skill level as a limit for that (limiting the maximum effective skill for the roll). Moreover I would also apply Familiarity (-2) if the character is not familiar with the "underground" part of the net.

On the other hand, as has been suggested, I would allow Streetwise as a complementary roll, too!

Regarding the typical "scene" connection stuff, it would fit very well IMO to give a good bonus (I'd use +2) if a character knows an underground starting point for the research. That bonus could be gained by informations from a contact for instance. (I'd give higher bonuses if the character knows many underground hot spots).


PS: In case the character wants to be stealthy in the net, too, trying to cover the tracks during the research, I would use Computer Hacking for that (or alternatively an extra Computer Operations roll at -5, if a campaign does not use the Hacking skill).
