@raq50 Thanks for the info. Looks like i have the same issue with sudden reboots. I will try disable MLO, as I currently not really use it

  Hi @Joseph-TP 

In my previous configuration, I was using a BE230 router with two BE3600 satellites in a wireless mesh setup without any issues. Since upgrading my fiber connection to 8Gbps, I decided to purchase a BE800 to serve as the main router.

My network handles over a dozen devices at peak times, including 6 PCs/Macs, 5 smartphones (Android/iOS), 3 tablets (Android/iOS), 3 watchOS, smart home devices (camera/aquarium) on an isolated network, Apple TV, Google TV, and a NAS.

All devices are running the latest firmware. The main unit is connected via wireless mesh to the other routers. I have performed tests by disabling various features, including the mesh itself. The problem clearly relates to the MLO (Multi-Link Operation) network. The router restarts approximately every 4 hours, suggesting a potential memory leak or buffer overflow issue.

Current Configuration:

• WAN: Currently connected via RJ45 (I have ordered a TP-LINK TL-SM5110-LR SFP+ module).

• WiFi Settings:

  • TWT: Enabled

  • OFDMA + MU-MIMO: Enabled

  • Smart Connect: Enabled

  • 2.4 GHz / 5 GHz / 6 GHz: All enabled, including a Guest Network with a Portal (I run a service center and have been in IT for 30 years).

  • IoT Network: 2.4 GHz / 5 GHz enabled.

• Networking & Security:

  • NAT: Enabled

  • DNS Privacy: DoH (Cloudflare)

  • Negotiation: Auto

  • RX/TX: Enabled for LAN/WAN

  • VLAN ID 35 + 802.1Q Tag for Internet

  • Dynamic DNS (no-IP) and VPN Client (NordVPN) enabled.

  • WMM and AirTime Fairness: Enabled

  • AP Isolation: Disabled

  • Port Forwarding: Active for NAS

  • Firewall: SPI enabled; Ping response disabled.

  • ALG: All options enabled.

  • Device Isolation: Active for 2 devices (IP Camera and Smart Aquarium).

  • IPv6: Disabled.

I believe I have listed the most critical parameters of my setup.
