After Upgrade to 3006.102.5: "Can't Add Zero Mac!"

Router: BE86U
Firmware Version: 3006.102.5

I've upgraded the firmware from the previous version and now I keep getting the message below. There's no other information or errors. Why is this happening? How can I troubleshoot and find out what's causing it? Thanks.

This message comes from the Trend Micro bwdpi engine, which often has that kind of annoying debug logging. Try turning down their EULA under System, then re-enable the specific TrendMicro feature that you want to use (like AiProtection).

@RMerlin, thanks for your reply.
  • I went ahead and withdrew from their EULA under Administrator → Policy.
  • This disabled AiProtection.
You were right. Once AiProtection was off, the annoying message disappeared.

I re-enabled AiProtection and accepted the EULA again.

As soon as I turn on any single option (Malicious Sites Blocking, Two-Way IPS, Infected Device Prevention and Blocking), or any combination of them, the "Can't add zero mac!" message comes back.

From what I understand, this is a closed source application, so you have no direct control over it. Is this something we just have to live with until Trend Micro fixes it?

Thanks!

Yes, unless it's something else in particular that triggers it for your setup, but there's no way to tell.
