BE9700 v1.0 Firmware Bug — Intermittent WAN Drops on Firmware 1.1.1 Build 20260113 rel.13713(5553)

#Firmware Update
Model:
Archer BE9700
Hardware Version: V1
Firmware Version: Firmware 1.1.1 Build 20260113 rel.13713(5553)
I am writing to report a persistent firmware bug on my Archer BE9700 v1.0 running firmware 1.1.1 Build 20260113 rel.13713(5553).
Setup:
- Router: TP-Link Archer BE9700 v1.0, Firmware 1.1.1 Build 20260113 rel.13713(5553)
- Modem: Arris S33v3 (DOCSIS 3.1, 2.5G ethernet port)
- ISP: RCN Astound
- Connection type: Dynamic IP via coaxial cable
Issue:
I am experiencing frequent, intermittent internet drops averaging every 30-60 minutes. The connection goes down for 1-2 minutes and restores on its own without any intervention. All devices (both wired and wireless) lose internet simultaneously during each drop.
I am experiencing frequent, intermittent internet drops averaging every 30-60 minutes. The connection goes down for 1-2 minutes and restores on its own without any intervention. All devices (both wired and wireless) lose internet simultaneously during each drop.
What has been ruled out:
- Two different modems (my personal Arris S33v3 and one provided by RCN) both experience the same drops, ruling out modem hardware
- RCN has re-provisioned the modem multiple times and inspected and repaired external line equipment — issue persists
- Router has been factory reset
- Tried both the 10G and 2.5G WAN ports — issue persists on both
- MLO is disabled
- DHCP is correctly configured
- Router is receiving a valid public IP from RCN
- The drops predate any changes on my end and began shortly after the firmware updated to 1.1.1
Key evidence from router system log:
The system log shows the router switching between WAN0 and WAN1 interfaces around the time of drops:
2026-05-12 13:49:08 Led Controller INFO [2108] Start to run WAN1_ON
2026-05-12 13:49:08 Led Controller INFO [2108] Start to run WAN0_OFF
2026-05-12 13:49:08 Led Controller INFO [2108] Start to run WAN1_ON
2026-05-12 13:49:08 Led Controller INFO [2108] Start to run WAN0_OFF
This WAN interface switching pattern has been reported as a widespread issue on other TP-Link routers and appears to correlate directly with the internet drops.
Additionally, users of the sibling BE900 V2 router have reported identical intermittent drop behavior after upgrading to firmware 1.1.1, suggesting this may be a firmware-wide issue across the BE router family.
I am requesting:
1. Confirmation of whether this is a known bug in firmware 1.1.1
2. A pre-release or beta firmware that addresses WAN stability and the WAN interface switching issue
3. Guidance on any settings changes that may stabilize the connection in the interim

I am happy to provide ping logs or any other diagnostic information your engineering team requires.
I'm desperate to find a fix to this. It's been maddening.

Hello @JasonL24 ,
You mentioned that 'removed the USB the connection has been 100% stable.' This matches the problem description of this solution:
BE600/BE9500/BE9700 V1 and BE550 Pro V2 May Randomly Auto-Reboot When SMB Is On After 1.1.1 Update
Judging from the beta firmware version, it should be possible to revert to the 1.1.1 Official firmware.
