Switch and AP Help - Switch is disconnected and devices continue to drop connectivity

New Contributor

I need some very dummy-proof help because I know very little about home networking; I've learned some info, but I don't know a lot of the terminology. I can't find any step-by-step instructions or help with my issues.

I have been working off of the Unleashed user interface (UI) online and the Unleashed app. I am having latency and connection issues with many of the devices in my home, but all APs (R510) are connected and working. I've called Spectrum and they show that I have a good connection, fast speed, and the modem and router support the speed I am signed up for.

The switch (ICX7150-C12P) shows as Disconnected in the UI. I first noticed it last September after a power outage took everything out. I had a Lennar Unleashed rep help me and he mentioned it's ok that the switch says disconnected, but that doesn't make sense to me. Why have a switch to just sit there in disconnected status? The rep said that after the power outage, the switch flipped from something-or-other to a router. We did a factory reset and that fixed the problem, but will this happen every time we have a power outage? Is there a procedure I should do after every power outage?

How do I find out what firmware version the switch is on? I found a YouTube video on how to update the firmware, but when I try to do it online (as opposed to downloading it to a USB drive), it doesn't upload. All 3 of the APs have the most up-to-date firmware, so I'm not concerned about those.

I have looked at a lot of forums, but people use jargon I'm not familiar with, so it hasn't been a lot of help. If anyone has any helpful docs to send me, I would greatly appreciate it! Thanks in advance for all your help!!



Hi @ luckadoo11


Thank you for the details provided, unfortunately, there is a known software defect that causes the problems you have described (after a power failure the switch will boot from the wrong partition which is the secondary containing the routing code, causing all the connectivity problems), now there are two ways to fix the problem, one will be to get access to the Switch CLI (command line interface) via SSH, Telnet or console, then you can copy what is in the image on the primary partition called switching code into the secondary partitions, so if the switch is booted back from the secondary as both partitions are now running switching code you will no longer have the problem; however, it is recommended to upgrade to the code where the problems have been solved 08095g UFI, but both partitions using the switch code image, the file will look like this SPS08095gufi. bin


1:Find the IP address of the Switch:

2:Once you know the IP address, gain access to the Switch via Telnet, SSH, or console.

3:Now you have accessed to perform an upgrade, which can be done via TFTP or using a USB

Do I need to follow this process every time the power goes out? Is there a warranty on these devices? We built in 2020, so I don't understand why this continues to be a known issue and the company, either Ruckus or Lennar, are not doing anything about it.

Hi @luckadoo11

No, If you have fixed the issue through CLI, then the issue  is not going to happen again. Since it is related to the software issue and you have removed the routing code image the issue will not happen again.

I followed the instructions a few weeks ago, and the issue was resolved. However, the power went out again yesterday, and I'm having the same issues. So, no, this was not a solution.
