1) Unplug the 2 VM Pods and return them.
2) Uninstall the VM Connect app from ALL devices in your home. ( don't ignore / skip this )
3) Using the VM Hub menu at http://192.168.0.1/ login with the Hub password
( not the Wi-Fi password, not your VM a/c password ) and visit the Wireless Settings.
4) DISABLE : Smart Wi-Fi / Windows Channel Optimization ( aka Wi-Fi Optimisation / One Wi-Fi etc )
This will re-enable the ability to have split SSID and to set Manual Wi-Fi channels for best stability.
Do not re-install the Connect app as it will endlessly try to re-enable "Wi-Fi Optimisation".
