In Windows 10 I received the message "An error occurred while reconnecting N: to\\NAS389CEE\Public Microsoft Windows Network: ..."

the message continued: The local device name is already in use. The connection has not been restored. This may be because the devices on the network have received a new IP address because they are on a new router. All devices accessed via Wi-Fi on the network are affected similarly. A computer accessing the network via an Ethernet connection are unaffected. I have tried rebooting the system without success. What do I need to do to get everything communicating again? The change was to introduce a mesh network as not all Wi-Fi devices could be reached via the original router.
