Model: Deco BE16000  
Hardware Version: V1
Firmware Version: 1.0.6 Build 20240725 Rel. 33400

So I logged into my main DECO 1600 - and noticed the following errors being thrown. I found them through the logs. My questions can someone explain what is causing these errors, and what is the path forward for resolution. 

 

1. Sun Feb 2 10:36:12 2025 daemon.err /usr/bin/apsd: uci_get_value:1349: Error: element type is not option:3  -- this is on one of my DECO 1600s which is NOT connect directly but is on Wifi. 

 

2. My second DECO is throwing the following error: Sun Feb 2 10:37:24 2025 daemon.err nrd[17834]: wlanifConvertToSingleStreamMCSIndex: Invalid PHY mode from driver: 0

 

Need to understand whats going on and how can I resolve this. 

 

My current setup is the following: 

1. ISP - is connected directly to my firewall which is a Protectli and using pfsense as my firewall. 

2. From my Firewall I have one of the DECOs connected directly to it. 

3. The Deco is in Bridge MODE where my Pfsense - provides the IP addresses. 

4. The Pfsense is configured for its DNS server - which is my raspberry pi running Pihole. 

 

Need help understanding the issue above, and how can I resolve it. 

 

Thank you

I am also in a similar setup with TP-link be25s behind a pfsense router in bridge mode (AP). I see this error a ton in my logs. Hoping someone will answer you!
