My setup:
TP-Link Archer C3150 router
Netgear R7000 Router in AP mode
Home Assistant is running on my RPi 2 via WiFi.
I’ve completely wiped my RPi and put a fresh installation of Jessie on it before using the All In One HA installer. Did this twice.
Using NMAP tracker, the only error I’m getting is from HA trying to query the Netgear running in AP mode.

I set up another AP (actual AP) which is a Netgear WN3500RP; but didn’t get any issues with this one.
Is this an issue with using a router in AP mode?
I use CloudMQTT, so I go to the control panel and use the WebsocketsUI to check if things are communicating. Not sure how you diagnose in Mosquitto or the embedded broker.
