Nmap inconsistent after router change

I had been running nmap for months without issue.

I recently changed from an Asus Ac68 to an Asus Ac88 and attempted to keep as much the same as possible.

However, right now both cell phones I keep track of for person detection with nmap go online and offline every few minutes.

Was wondering if anyone has any ideas about any settings that could cause this. I’m running the latest Merlin firmware if that matters. Tried multiple reboots of HA and my router with no luck.

My tplink smart plus also will not connect since the router change. Error logs say host is not reachable, despite me being able to ping the device from HA.
