Manage home connections, sharing and temporary access

Keep connection comparisons separate from sharing a connection with another device. Decide whether the network is trusted and record the original state before changing its profile or sharing settings.

Before choosing a task

  1. Check the connection and route; for comparisons, use the same task and similar conditions.
  2. Choose who may connect and what is shared before enabling a hotspot or file access.
  3. Check data use and reconnection afterward, ending temporary connections or unnecessary sharing.
