Connection fails when on master, ok on node

[HotWheels]

I have the 2 3100's in ai mesh. Master is upstairs hardwired to a node downstairs. When I'm upstairs on my iPad using the 5ghz the internet just goes out, but it still shows signal and connection. On the iPad itself I can cycle the WiFi off then back on and it works again. Have the same issue loosing connect with my Alexa when it’s on 5ghz, no issues with 2.4
Don't have this issues when downstairs using the 5 or 2.4? Ideas?

1. Disable 'Smart Connect'.
2. Use a same SSID for 2.4 and 5. Assign channels manually.
Reason: A firmware sucks. Go to hell ASUS.
