Hi, welcome to the community.
Regarding the "network reset", do you mean factory resetting the Deco nodes and reconfiguring them, or rebooting the Deco nodes?
1) If you reset the Deco and reconfigure it, all the previous configurations on it will be removed.
2) Rebooting the Deco node won't remove the connection preference settings. If this happens on your Deco nodes, please send us screenshots of your connection preference settings before and after the Deco reboot.
Then, please follow the instructions below to send us the Deco app log. After that, attach your reference number (such as email TKIDXXX) to the thread or reply to us if you have sent the app log.

Best regards.
