Select the correct object in the app and measure the result before overriding automatic connection choices.
Supported Deco models can offer connection preferences for a satellite and for an individual client. These controls affect different links. Choosing the wrong one can leave the original problem unchanged.
Identify which link is unsuitable
If a satellite repeatedly connects through a distant node, investigate its upstream source. If a television connects to an inconvenient Deco while the satellites themselves are healthy, investigate the client’s serving-node preference.
Confirm feature availability
TP-Link documents the feature for selected models and firmware, in Router and Access Point modes. The label may appear as Connection Preference or Specified Connection. A guide showing the control does not prove it exists on every installed unit.
Record the automatic arrangement
Save the current network map and a short result for the affected task. Note the client or satellite you intend to change. This gives you a baseline and prevents an unexplained manual preference from becoming permanent.
Apply one justified preference
- For a satellite, choose an upstream source with a viable link.
- For a stationary client, choose the intended serving node and supported band where offered.
- Keep a mobile client’s movement requirements in mind.
- Leave unrelated devices on their current configuration.
Test beyond the nearest room
A preferred node that works well beside the television may be unsuitable after moving that device. For a satellite, check clients behind it and any downstream dependencies. Proximity alone does not prove a better radio path through walls.
If the preference does not produce a repeatable improvement, restore the previous automatic setting and investigate placement or backhaul. Avoid accumulating manual choices simply because the controls are available.
Document the reason for any preference you keep. A future node relocation can invalidate it, so include the setting in maintenance notes. The right outcome is a clearer, more stable connection path for a particular task, not a network map forced to look symmetrical.
