it's a few day that i'm getting mad to add a new h320 to my h510 network.
For some reasons that i do not understand after getting the ip address it remains stuck on "Building the Unleashed Network. It may take a few minutes."
hard resetted several times and tring different configurations, it never joins the existing unleashed network, but rather creates a new one (if not connected with an ethernet cable).
I also had issues with a bad firmware update, but with ssh this has been fixed.
Thank you for all the tips.
