Maybe it is one of them bazillion fixes in the Unofficial patch?
Very much possible. Doesn't sound too wrong to fix this, but still, UFO4P does have a tendency to verschlimmbessern
* things.
IMO, the best (and hardest) way to "fix" this would be to add a raider quest for the teleporter. Something like: after you get the courser chip analyzed, a new quest starts, with the objective "Talk to your Raiders about the Signal Interceptor", where you then can build the teleporter with the raiders.
You can then talk to Jammer about it. He either says "Go talk to Ophelia, she's the tech guy" or something like "I can't build it, but I think I might be able to get in contact with someone". The quest then turns to "Wait for Jammer to find a technology specialist", which when completes and turns to "Talk to Ophelia" as soon as you have her.
It then leads to Institutionalized, as usual.
Ophelia would then give you the network scanner holotape. Though, not sure how easy or hard it would then be to make the BoS/RR quests work, which have parts like "Go talk to Sturges/Tinker Tom/Ingram to get the Holotape back", to include Ophelia.
