Archer BE400 AP Mode acting as EasyMesh Controller and BE5000 "sync-server" Restart Loop
Hello, I am experiencing issues with my EasyMesh setup using Wi-Fi 7 routers in Japan.
Note: I selected Archer BE230 for the satellite unit in the model field because Archer BE5000(JP) was not listed, though its specs are similar to the BE230.
[My Environment]
-
Main Unit (Controller): Archer BE400(JP) (V1.0 / Firmware: 1.1.2 Build 20251021)
-
Satellite Unit: Archer BE5000(JP) (V1.0 / Firmware: 1.1.0 Build 20260108)
-
Upstream Router: NTT PR-500MI (Required for VoIP/Optical services; functions as DHCP server)
-
Topology: PR-500MI <--(Ethernet)--> BE400(JP) (AP Mode) <--(Wireless)--> BE5000(JP)
Issue 1: BE400(JP) acting as EasyMesh Controller in Access Point (AP) Mode
According to the TP-Link FAQ(https://www.tp-link.com/jp/support/faq/3529/), Archer BE400 should not typically function as an EasyMesh Controller in Access Point Mode. However, my BE400(JP) allows me to enable EasyMesh and connect the BE5000(JP) as a satellite while in AP Mode.
-
Initially, when DHCP was set to "Auto," the log showed frequent DHCP renewals every 35 seconds.
-
After switching to a Static IP and disabling the DHCP server manually on the BE400(JP), the logs stabilized.
-
Question: Is it officially supported for the BE400(JP) to act as an EasyMesh Controller in AP Mode? Or is this unintended behavior?
Issue 2: BE5000(JP) Satellite Log - "monit restart sync-server" Loop
Regardless of the controller's settings, the satellite BE5000(JP) keeps recording the following logs every minute: 2026-04-13 21:00:01 MONIT Notice [25984] monit restart sync-server 2026-04-13 20:59:01 MONIT Notice [20256] monit restart sync-server
Current Symptoms: Devices near the BE5000(JP) often stay connected to the BE400(JP) (weak signal) instead of roaming. I suspect the "sync-server" loop on the satellite is preventing proper mesh synchronization/steering.
Questions:
-
Is the BE400(JP)'s behavior in AP Mode considered "normal" for this specific Japanese model?
-
How can I resolve the "monit restart sync-server" loop on the BE5000(JP)?
I would appreciate any insights or firmware recommendations for these Japan-specific models. Thank you!
