Ok, this solved the issue. Well, it made the issue go away, nothing is solved. Can happen tomorrow again.
One enhancement request, can you please, in the next firmware, set a default IP address that is not the most used IP address for default gateways in the world? The moment you do a factory reset the whole network goes down because of an IP conflict with the more important device on the network, the default gateway.
Make it DHCP, please.
Case closed. You can close the ticket.
