Where to establish Fortnite Device Uplink connections

Fortnite Device Uplinks feature in every stage of the Rebuilding quests, acting as the trigger to access the second phase of your mission in either Imagined Order or the Seven territory. These small blue discs project a hologram when you get close to them, providing the gateway to your progress through these Fortnite tasks. The first group of them appear around Condo Canyon, Coney Crossroads, and Command Cavern, but expand further across the island as you work your way through. If you're unclear how to start things off, we've got all of the Fortnite Device Uplink locations plus details of how to complete every Rebuilding quest.

How to use Fortnite Device Uplink for Rebuilding Quests

To use a Fortnite Device Uplink, you simply need to approach one of the blue discs embedded in the ground and walk through the hologram projected above it, with no specific interaction required. This will then trigger the second part of each Rebuilding quest in turn, which we'll expand on below.

You'll find a cloaked IO Build Jammer in lots of locations around the island, but to reveal it you'll need to look for a little white satellite dish icon on the map. When you approach it, the IO Build Jammer will appear as you get close, then you can smash it. They will still keep popping up on your map even after you beat this quest, so don't worry if you continue to see them.

If you're struggling to find any cloaked IO Build Jammers, the map below isn't exhaustive but reveals all the locations we've discovered so far:
