In the quest Killing In the Name you have to hack into a series of routers. The first router was bugged for me, I couldn't hack into it and it wasn't interactive at all. Luckily I had an auto save from right before I began the quest and thankfully on the 2nd attempt it worked, Johnny Silverhand appears by the router and it was hackable this time.

So yes, the first part was hte part that bugged out on me, the router on the wall of the apartment building on the fire escape.
