It might be annoying if your TP-Link Deco keeps going offline, particularly if you depend on dependable internet for smart devices, streaming, or work. Here's a thorough approach to troubleshooting it.

1. Verify the color of the LED:

  • Online status is shown by solid green.
  • Ready for setup is indicated by pulsing white.
  • No internet is shown by solid red.
  • Red pulses indicate a disconnect or system issue.

2. Typical Reasons:

  • Unstable ISP connection: Occasionally, your modem or ISP is the problem rather than the Deco. Connect a gadget straight to the modem to test.
  • Weak Backhaul Signal: Your Deco units could fall off the mesh if they are too far apart. Consider cabling them with Ethernet (Ethernet backhaul) or bringing them closer.
  • Firmware Problems: Random dropouts may be caused by outdated firmware. Navigate to "More > Update Deco" in the Deco app to see if there are any changes.

3. Reset & Power Cycle:

  • Turn off your modem and all of the decos.
  • Turn on the satellites after turning on the modem and the main Deco.
  • Reset the problematic Deco using the reset pinhole and re-add it using the app if the problems continue.

4. Prevent Interference: Mesh transmissions can be disrupted by cordless phones, microwaves, thick walls, and even other routers. Put your decos in prominent, open areas.

5. Utilize the Tools in the Deco App:

Select "Network Optimization" or "Test Internet Speed" to view the performance of each Deco node. Another important feature for repositioning is the ability to tap a device to discover which Deco it is linked to.

More Complex Fixes:

  • Turn on "Beamforming" or "Fast Roaming" to improve handoffs.
  • If DHCP is unreliable, think about utilizing static IPs.
