I have 3 deco x50-poe, all connected by cable, to different switches, decos are in access mode, all cables are working and tested.

ER605  -> TL-SG1008MP
                            └──Deco - Living Room
             ->TL-SG1005LP
                       ├── Deco DB0C
                       └── Deco D964

two switches are connected to the router ER605, Living room deco connected to TL-SG1008MP, other 2 decos are connected to the TL-SG1005LP.

 

The problem is that mobile app shows that one of the deco DB0C or D964 communicates with main deco Living room through Wi-Fi and not Ethernet

 

 

How to force deco to communicate only through wired blackhaul? Is there something I can check in the log?

 

System logs contain the following messages:

• "backhaul_iface"
• "wifi backhaul is enable"
• "backhaul enabled 2g"
• "backhaul enabled 5g"

I cannot find any indication that Ethernet backhaul has been established.

Additionally, the logs repeatedly show:

• "Failed to read AP info"
• "No enough AP info exists"

which suggests the mesh topology database may not be built correctly.

 

 

 

 All Three Nodes — Post-Reset Analysis

  What's identical across all nodes (main, 2, 3)

  All three boot logs are structurally the same:
  - backhaul_option is 3 read from config → AWN daemon overrides to backhaul_option:1 (WiFi)
  - backhaul_ifnames value:ra0,rax0,ath22 — Ethernet still excluded from backhaul
  - 4 Segmentation faults at 12:29:07 on every node
  - sync-server/mesh_dev_list doesn't exist — mesh device registry never created
  - tmpsvr: Error: tmp_trans_relay — TMP relay still broken

  The factory reset did not clear backhaul_option=3. It survived the reset.

  What's new and positive

  At 13:23:00 the main node's imsnoop (multicast bridge manager) starts seeing satellite MACs for the first
  time:

  imsnoop: mcManagerMCProcess: vlan node 0 - F0:09:0D:1B:D9:64, add it to encap table
  imsnoop: mcManagerMCProcess: vlan node 0 - F0:09:0D:1B:DB:0C, add it to encap table

  This confirms both satellite nodes are physically reachable via Ethernet at L2 level — the cables, switches,
   and bridge are all working. The hardware is fine.

  At 13:23:06–10 on both satellites:
  awnd_config_set_eth_neigh_interface: Success to set repacd STA 1
  ntp check success!!!
  Ethernet neighbors detected on the satellite side too.

  Why it's still broken despite physical Ethernet working

  The L2 Ethernet is up, but the higher-level Deco mesh protocol (TMP) can't use it because:

  1. backhaul_option=3 (PLC mode) forces WiFi fallback — the firmware never tries to negotiate Ethernet
  backhaul
  2. tmpsvr tmp_trans_relay keeps failing — TMP packets can't be relayed between nodes (lines 759–760,
  813, 976)
  3. IMPROXY (multicast proxy) is crashing at every retry:
  IMPROXY: Disable IGMP, there is not igmp upstream interface
  3. In AP mode, br-wan has no IP, so the multicast proxy has no upstream — TMP relay depends on multicast and
   breaks with it
