Thank you for contacting Lennar Home Community.
Hope you are doing well!!!
As per the case description, I could understand that after installing a new Router you are getting Switch Disconnected status on the Unleashed dashboard.
Please follow the below steps and help us with the queries,
1. To check this issue, we must identify the ‘current’ IP address assigned by your local router to the switch ICX-7150-C12P
I will leave you a guide on how to perform an IP scanner on your local network to identify the switch IP address very easily.
How to find my Ruckus “Devices IP address” using free applications:
2. Once we identify the IP address of the switch proceed to access remotely to the device “Command Line”
How to remotely access to 'ICX 7150-C12P' or 'access points' "Network devices":
If you can access the Command line should look like this:
ICX7150-C12 Router> OR
Please enter the below commands once you log in to CLI and share the output.
Note: Hit Enter to accept each command
Please share the output of the above commands or share the screenshots if stuck at any step or error (if any) and let me know if you have any queries in this regard.
Thank you again for your patience.
