ICX-7150-C12P - Connectivity Issues after Power Outage

at25

Recently had a power outage few weeks ago and after the power returned, the internet has been unstable every 30-60 seconds. It is a Lennar home that has the ICX-7150-C12P switch with three R510 APs connected to an AT&T Fiber Modem (BGW320-505).

Ethernet and Wi-Fi connection is stable but it's the internet that times out every 30-60 seconds. Websites will not load sometimes, Ring doorbell will time out after 30-60 seconds when viewing live feed, and Teams/Zoom/Wi-Fi calls will disconnect randomly.

When logging into the unleashed network, it shows the internet is disconnected with a red "x" under DNS.

Steps I have taken so far to diagnose:

Reset the switch and updated the firmware to switch firmware for both primary and secondary boot.
Reset the APs and updated the firmware.
Multiple power resets and connecting one AP at a time.
Verified the switch boot is in switch mode.
Verified that when I connect directly to the AT&T network (ethernet or Wi-Fi), the connection is always solid with no internet timeouts.

My suspicion is the switch is faulty. I have pictures of the setup in case that can help.

Hi Imran,

The internet is fully functional now. Before I performed a factory reset, I disconnected all Ethernet ports from the switch except for 1 AP and the gateway. I then noticed the WiFi was working flawlessly. I plugged everything back in and noticed a ethernet cable labeled D.M. (I assume this stands for demarcation which I believe is a telephone line) which I kept unplugged. When I plugged it back in, I saw the same issues. So I have it disconnected now and the system is functional.

Also, AT&T tried to help and modified the IP passthrough to include the switch MAC address. Internet still works fine but any issues with that?

Thank you for your support.

Hi @at25

I hope this message finds you well.

Thank you for your response and for providing the update.

It's great to hear that the issue has been resolved.

However, I kindly request that you disable IP Passthrough. With Passthrough enabled, your devices are assigned public IP addresses by your Internet Service Provider’s router, which is not recommended. Devices should instead be assigned private IP addresses for security and optimal network performance.

Should you have any questions or need further clarification, please don't hesitate to reach out.

Thank you again for your patience.

Best regards,

Ports 1-3 are used by R510 APs.
Port 11 is connection to the AT&T router/modem.

Hi @at25

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 intermittent internet connectivity.

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

Please unplug the ethernet cable of port 11 of the Switch that comes from the ISP (Internet Service Provider’s) Router and plug it back into any other available 1-in-12 ports as highlighted in the below screenshot. Once done, please reboot (unplug and plug from the power outlet) your ISP Router once and once it comes up, check the internet connection stability via RUCKUS.

Please let me know how it goes.

Thank you again for your patience and understanding.

Best regards,

Hi Imran!

Thank you for the quick reply. I changed it to port #12 and I am still experience the same issue. Before the power outage, it used to be connected to C1 when it operated normally.

Hi @at25

Thank you for your recent correspondence and update.

We may need to check some configurations of your RUCKUS ICX-7150-C12P Switch to troubleshoot this issue.

To proceed with troubleshooting the issue, please follow the steps outlined below to access the Command Line Interface (CLI) and provide the necessary command outputs:

1. First, 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

2. Once you have identified the IP address of the switch, proceed to access the Command Line Interface (CLI) of the RUCKUS ICX-7150-C12P switch. Here is a guide on how to access the CLI:

/kb/articles/8-how-to-access-the-command-line-interface-cli-of-the-ruckus-icx-7150-c12p-switch

If you can access the Command line the prompt should look like the below:

ICX7150-C12 Router> OR

ICX7150-C12 Switch>

3. After successfully accessing the CLI, please execute the following commands and provide the outputs:

enable

show version

show flash

show inline power

show inline power detail

show interface brief

Please share the command outputs or screenshots if you encounter any issues or errors during these steps.

Feel free to reach out if you have any questions or require further assistance.

Thank you for your cooperation and patience.
