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

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.

Hi @bs-tp-ninja ,
Have you enabled the SMB sharing? If not, the reasons for the abnormality may be inconsistent.
