Lennar Home ICX 7150 slow internet until reboot

New Contributor III

I have a Lennar home with 3xR510 WAPs all connected to a ICX7150 switch running over Cat6e. We have Xfinity 1gb service. When i perform a Analiti speed test connected directly to the xfinity router with a device i get ~500mpbs. Once I connect a device through the existing Ruckus network the speed drops to ~40-70mbps. If I reboot the switch the speed goes up to ~500 which is expected. Not sure what I can do to resolve this and I have to reboot roughly once a week, any help would be appreciated, thanks


Hi @Mymnte 

Thanks for the update ! 

Please run the following commands to check the cables status 

clear cable-diagnostics tdr 1/1/2
phy cable-diagnostics tdr 1/1/2

Note : Wait about 3 minutes to run the following command

show cable-diagnostics tdr 1/1/2

clear cable-diagnostics tdr 1/1/3
phy cable-diagnostics tdr 1/1/3

Note : Wait about 3 minutes to run the following command

show cable-diagnostics tdr 1/1/3

clear cable-diagnostics tdr 1/1/4
phy cable-diagnostics tdr 1/1/4

Note : Wait about 3 minutes to run the following command

show cable-diagnostics tdr 1/1/4

Hi @Mymnte 

That cable needs to be replaced with a good one! This can affect performance causing the speed to be very slow through that access point.

It may be that one end of the cable is damaged or the cable is bent.

Hi @Mymnte 

Hope you are doing well! 

If there was a blackout or power outage and the switch reboot because of that, most possible your switch starts running the wrong code which we call ‘routing code’ this is a known issue.




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

There we are going to see 2 important things the

MAC address: Physical address of the device this never changes

An IP address is a unique address (logical) that identifies a device on the internet or a local network like your home (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 ‘currently’ IP address assigned by your local router to the switch

-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 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 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"

If you can access to the Command line should look like this:

ICX7150-C12 Router>

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 )

How to Fix Routing code issues on Lennar Home users via CLI

Or WEB access option

4-If the access via IP address is not possible here is a guide how to access to the Switch via console (cable access between your PC to the ICX 7150-C12P) in this case we need a USB type C to USB standard or Console cable Rj45 to USB. 

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'

I have actually done these steps about a year ago due to power outages but it was the primary that needed to be copied to the secondary. This fix resolved the issue of no network or very very slow after reboot. Everything has been working great for about a year, even after a couple power outages. Just recently though without any outage the networks speed will fall off on its own, a reboot brings it back to full speed.

Hi @Mymnte 

1-Can you check if this is happening on the ISP local (  router )  ? 

2- Is this happening on a specific Access Point ? 

3- Please make sure that wired is ok. 

4- Please connect a PC directly to the Ruckus Switch ICX-7150 to see if you are having the same connectivity issue
