Lennar home - slow wifi

New Contributor

Hi, I have been dealing with slow wifi for a while now. The system came with Lennar home. I tried to reset everything but that didn’t help. 

Any suggestions on what i should do? Thanks



Hi @DeanT 

Hope you are doing well ! 

If there was a power outage most possible that switch start running the wrong code for that reason there are many symptoms

Smart devices like Amazon's Alexa not working as intended.
Unleashed dashboard sometimes not showing as "Connected" on the Internet tab.
Websites not loading.
Several connectivity issues.



An identifier of this problem is that it comes out as Switch-Router in the unleashed dhabsoard.

There we are going to see 2 important things the

MAC address: Physical address of the device this never changes

The IP address : is a logical address assigned by your local router to the device (this can change and may not be the same as the one shown on the dashboard)

1- To fix this issue, we must identify the IP address of the switch 'currently'

-We can try the IP address that shows in the dashboard copy and paste it in the URL if that redirects you to the login page for the ICX-7150-C12P that is the correct one if not I will leave you a guide how to perform a IP scanner on your local network to identify the switch IP.

2-Once we identified the IP address of the switch proceed to access remote to the device 'command Line' 

How to remotely access to 'ICX 7150-12P' or 'access points' "Network devices"

3-Here is a quick guide to understand how to fix the 'routing code issue' but basically you need only need to run the following commands once you are on the command line 'CLI' 

Note: Hit Enter to accept each command


copy flash flash secondary 

boot system flash secondary yes 


ICX7150-24P Router>enable (hit enter to accept the command)
ICX7150-24P Router#copy flash flash secondary (hit enter to accept the command and wait  : until the flash finished )
ICX7150-24P Router#boot system flash secondary yes ( hit enter to accept the command  : the switch will reboot )

4-If the access via IP address is not possible here is a guide how to access using a console cable ( usb to usb type C ) 

How to console in the ICX-7150-C12P

Once you are log in the ICX-7150-C12P please follow up the same steps that are on point '3'

Hi, I ran the commands you specified but it's giving me an error. How should I proceed?

No password has been assigned yet...

Unable to find a UFI image copy from. Please reload master with appropriate UFI image to proceed with flash-flash copy

Hi @DeanT 

Thanks for the update ! 

could you please run the following commands :

Show version 

show flash 

Also most possible you need to perform an upgrade to the switch here are a couple of guides how to do it:
