Model: Deco BE68
Hardware Version: V1
Firmware Version: BE68(EU)_V1_1.1.2 Build 20251028

Hello,

after replacing the main unit in my Deco mesh from BE65 → BE68, I started experiencing cyclic wireless backhaul disconnects. Initially it affected only two BE25 nodes, but I have now confirmed that a BE65 node on wireless backhaul to the BE68 can also disconnect (less frequently). At this point I need a clear resolution: either a firmware fix (targeted beta/engineering build) or confirmation that this behavior indicates a faulty unit and should be handled as RMA/return.

Setup

• Total 11 units: 1× BE68 (main/router), 1× BE65, 9× BE25

• The issue affects mainly:

  • 2× BE25 in the garage (wireless backhaul directly to the BE68)

  • BE65 node (wireless backhaul to the BE68) can also disconnect, but less often than the BE25 nodes

• All other nodes (including BE25 Outdoor) remain stable

Symptom (hard evidence)

• Deco log shows repeating pattern: disconnected → reconnected after ~2 min 31 s

• Example events showing the same pattern:

  • 02:14:05 → 02:16:36 = 2:31

  • 06:24:34 → 06:27:05 = 2:31

• Disconnects occur throughout the night, causing brief camera stream drops and short connectivity loss for clients behind the affected nodes

Before the replacement

• With the same topology and BE65 as the main unit, the network was completely stable

• The issue started immediately after switching the main unit to BE68

Steps / tests (systematic elimination)

• Configuration migrated from BE65 to BE68; the main unit is in the same physical location

• Tested on BE68:

  • Stable FW: BE68(EU)_V1_1.1.2 Build 20251028 (no change)

  • Forum beta: 1.1.6_build_20251113_Beta (no change)

• Wi-Fi settings are fixed (no optimization):

  • MLO disabled

  • 2.4 GHz fixed to 20 MHz (note: after “Optimization” the BE68 only offers channels 1–11)

  • 5 GHz fixed to channel 36 / 80 MHz (EU region; manual channels up to 128)

  • Multiple restarts and firmware changes did not stop the cyclic disconnects

Key finding / workaround

• If I replace the problematic garage BE25 with a BE65 used as a satellite, the disconnects are significantly reduced (lower frequency) and the link is generally more stable.

• However, I later confirmed that the BE65 on wireless backhaul to the BE68 can also disconnect occasionally (just less frequently than the BE25 nodes).

• This indicates the problem is not limited to a single BE25 unit, but points to wireless backhaul instability on the BE68 as the main/root (firmware or hardware).

Request (please advise clearly)

1. Is this wireless backhaul instability on BE68(EU) V1 (with BE25/BE65 satellites) a known issue?

2. Is there a newer stable firmware than 1.1.2 Build 20251028, or a targeted beta/engineering build that specifically addresses wireless backhaul stability?

3. If no firmware fix is available, can you please confirm whether this behavior is consistent with a faulty BE68 unit and should be handled as RMA/return?

Thank you.
