AP fails every hour with Hearbeat failure message

mnk23227

The AP's are connected and functioning. They are updated via the unleashed browser. The AP go down every hour with the message:
AP[8c:fe:74:36:81:90] joins with uptime [90479] s and last disconnected reason [Heartbeat Loss]

The unleashed Web UI shows the switch is disconnected. The switch is on version
ICX7150-C12 Switch>show version

The switch is not able to ping my device (mac) nor can the Mac ping the switch. Therefore TFTP to transfer the image is not working. The Web UI to switch was working but now has stopped.

The switch connects to a TPLink router provided by ISP.

Hi @mnk23227 ,

Greetings!!!

Thank you for reaching out to the RUCKUS Lennar Home Community.

We appreciate your patience and understanding as we work to resolve the issues you are experiencing with your RUCKUS setup.

Based on the information provided, it appears that you are encountering Heartbeat loss errors.

We apologize for any inconvenience this may have caused and are committed to assisting you promptly.

To help address this issue, please try the steps below:

On your switch while it's plugged into the outlet, do you see any lights on? (Amber or green) Please let us know which lights are on. (Please refer to the below picture and share a picture of the same, showing the light status and the FULL Switch panel cable connections to the Switch ports)

Unplug the Access Point cables from the RUCKUS Switch ports.
Reconnect them to any other available ports (1–12) on the switch. (Refer to the screenshot below.)
Once done, please check if the heartbeat loss error persists.

We also suggest you upgrade your ALL RUCKUS R510 Access Points to version 200.15.6.12.304 which is recently released.

Could you please log in to your Unleashed system on a LAPTOP WEB BROWSER using the Master AP IP Address OR https://unleashed.ruckuswireless.com/ ?

If link doesn't work, identify the current IP address assigned to the switch ICX-7150-C12P by your local router. You can use an IP scanner tool to easily locate the switch's IP address on your network. Here is a guide on how to perform this using IP Scanner free applications:

/kb/articles/10-how-to-find-the-ip-address-of-the-ruckus-devices-switch-and-aps-using-ip-scanner-free-applications

You should see the below-Unleashed dashboard after finding the IP Address of the AP. Try to log in

Once you login to the AP through web browser, please upgrade the AP to the recommended version.

Please follow the below RUCKUS Lennar Knowledge base self-help article which will help you to upgrade the Ruckus AP to a recommended version 200.15.6.12.304

Please check and let me know if you have any queries in this regard.

Thank you again for your patience and understanding.

My AP are on 200.15.6.212.27 which was released on 2025-07-01
You're asking me downgrade to 200.15.6.12.304 which was released on 2024-01-15
Is that correct? The AP are accessible via the Unleashed Web UI.

The switch lights do not show any errors. All lights are green. The AP are between 1-12 ports. The router is connected to 13/14 port as you can see from the output of the switch.
The switch is hard coded to 192.168.X.3 and was accessible via web UI but randomly stopped responding to web requests. The Mac cannot ping the switch. It gets Host is Down or unreachable. The switch configuration is also posted.

Hello @mnk23227,

Thank you for the response.

Could you please share the picture of the Switch showing the connection of the ports?

Also, please try to remove the Access points from the Switch and reconnect to any one of the other 12 ports on the Switch.

Please let us know if you have any queries in this regard.

Thank you for your patience and understanding.

The problem was about DHCP lease renewals. I checked the detailed system logs, DHCP was renewing leases and changing the IP addresses. The AP had to request to delete the old IP and register new one and thus causing a blip.
After assigning static IP and increasing the DHCP lease duration, the problem is resolved.
The switch update is still an issue. How can I find older version of software?
The switch is running 08.0.70T211 and cannot be registered on unleased web ui which requires the switch to be on 08.09 and higher. I cannot upgrade directly from the current version to the latest version and I cannot find the older firmware packages.

Hi @mnk23227

Greetings!

Thank you for your response and the update.

Yes, assigning a static IP address and increasing the DHCP lease duration should help resolve the heartbeat issue.

Regarding the switch upgrade, your device is currently running an older non-UFI version (08.0.70). The recommended version for Lennar RUCKUS switches is 08.0.95g.

Please follow the upgrade path below to reach the recommended version on your Switch:
08.0.70T >> 08.0.80f >> 08.0.95g

For detailed step by step instructions, please refer to the RUCKUS Lennar Knowledge Base self-help article below:
/kb/articles/1-how-to-upgrade-ruckus-icx-7150-c12p-from-non-unified-forwarding-image-ufi-to-a-stable-ufi-version

Kindly proceed with the upgrade at your convenience, once done it can be added to the Unleashed system, and feel free to reach out if you need any assistance during the process, I’ll be happy to help.

Thank you again for your patience and understanding.
