My sensor was working but occasionally would disconnect. I needed a new router so I installed a ZenWifi AX3000 mesh network. It gives a very strong signal to the sensor on the 2.4GHZ band. I got the sensor connected but it doesn’t stay connected. It will do a couple of readings and then drop off. The router shows a Connection Quality of -54 dBM. I get maximum bars at the sensor. I also have other smart devices working fine on the 2.4 GHZ band. Security is set to WPA2. If I connect to the PurpleAir network I can see live readings and I can see my 2.4 GHZ signal with all bars. Now I get a Wifi connection failed after repeatedly typing in the password. I’m not sure what to do next. It looks like the sensor is working but the wifi from the sensor seems to be having an issue.
