Saturday
Model: Archer BE800  
Hardware Version: V1
Firmware Version: 1.4.1 Build 20260119 rel.30658

I am writing to report a serious stability issue with my Archer BE800 (V1, Firmware: 1.4.1 Build 20260119 rel.30658).

The router frequently freezes or reboots, specifically during the morning hours (between 6:00 AM and 8:00 AM). After analyzing the system logs, I have identified that the cause is an ICMPv6 Flood (Router Solicitation) originating from iOS devices (iPhone 14 and others) in my network.

Problem Details:

  • Behavior: Certain iOS devices enter a loop where they send hundreds of receive solicit(RS) requests per second.
  • Router Reaction: The Archer BE800 attempts to respond to every single request with a send advertisement(RA). This causes the CPU usage to spike to 100%, leading to a total system hang or an automated watchdog reboot.
  • Network Environment: My ISP is Deutsche Glasfaser (Germany), using DHCPv6-PD.
  • Troubleshooting done: Resetting network settings on the iPhones ("Forget this network") only solves the issue temporarily. The problem eventually migrates to other Apple devices in the household.

The Archer BE800 should have a built-in "Flood Protection" mechanism to drop these excessive packets instead of allowing them to crash the entire system. As this is a flagship Wi-Fi 7 product, I expect much better resource management and stability.

Attached to this email:

  1. System logs (syslog.log) showing the ICMPv6 flood just before the crash.
  2. Screenshots of the router's client list and IPv6 configuration.

I kindly request you to forward this to your engineering team. This appears to be a firmware-level bug in how the BE800 handles high-frequency ICMPv6 traffic. I would appreciate a beta firmware fix or information on an upcoming official update that addresses this vulnerability.

I look forward to your assistance.

 

Best regards,

Daniel

Re:Archer BE800 - Constant Reboots / IPv6 Solicitation Flood from iOS devices
8 hours ago - last edited 8 hours ago

Hello @DanielOK ,

Thanks for contacting our community.

 

May I know if your network topology diagram is as follows:

ISP modem—BE800)))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

 

Please install the latest firmware of Archer BE800-v1: Archer BE800_V1_1.4.1 Build 20260313 (Pre-Release Firmware) 

For more details, please refer to New Firmware for Archer BE800 V1 to Support VPN Merge,Guest/IoT Network Extend in EasyMesh, and More.

 

If you're not connecting an iOS device, how is the network connection on other devices? 

On the affected iPhone, try:

  • Settings > General > Transfer or Reset iPhone > Reset Network Settings.
  • After connecting to Wi-Fi, in the Wi-Fi settings, turn off the "Private Address" option for your home network.
  • Check whether any VPN, network monitoring, or "power saving" apps are running in the background on the iPhone. These apps can sometimes interfere with the network stack; try uninstalling them.
