Switch problems (potentially)

kaz — Mon, 30 Mar 2026 22:19:44 GMT

Since swapping our 7150 C12P with a replacement sent to us by Ruckus, things had been working. It worked out of the box without setup, and I didn't bother updating the firmware or changing the settings, partly because I didn't have the passwords and stuff to log into the system. In recent days, our phone calls have become very choppy or dropping (we use a Wifi booster because we get no Verizon signal here) and the internet speeds are dropping drastically. Speedtest will show 1 Mbps for several seconds before ramping up to a mere 80 Mbps (we get at least 200-400 Mbps depending on the place in the house). I'm thinking it might be because the settings on the 7150 switch are generic from the last user or factory and need to be optimized. Please advise.

The default username/password on a switch will be super/sp-admin

As long as the switch is running in switch mode and not router mode, the switch is not the problem. As shipped from the factory, switches forward packets as fast as the hardware allows and there are no options you need to modify to ‘optimise’ this.

You can test the speed of the switch by plugging a laptop in with an Ethernet cable and running a speedtest. This will show you the maximum speed to the internet that your router can support.

Hi @kaz

Thank you for your response through Private Message.

Based on the picture you shared light status of the RUCKUS Switch and Access Points seems normal. However, it appears that the white cable from your Internet Service Provider’s (ISP) router is connected to the incorrect port on the RUCKUS ICX-7150-C12P Switch. The cable should be connected to one of the 1-12 ports on the switch (please refer to the screenshots below). Kindly unplug the cable and reconnect it to the appropriate port. Afterward, please reboot the ISP router by unplugging and plugging it back into the power outlet. Once done, check your internet connection.

Please let me know how it goes.

Thank you again for your patience and understanding.

Oh no. My reply didn't seem to get registered here. Typing it again...

So I tried what you suggested and I get no internet anywhere (put ISP into one of 1-12 and rebooted, and waited). The lights on the switch are all green, though. I then put the ISP cable back into C1 and everything works again, except like before I'm getting slower throughput (100 Mbps down and 40 up) in my study, when I normally get at least 200.

I tried doing what you said (putting ISP into one of 1-12 and rebooting). I get no wifi now, even after waiting. If I plug the ISP into C1, it starts working again, but still slow. I'm only getting like 100 Mbps down and 40 up in my study when I usually get at least 200 each way.

It must be the switch's settings. I can't log into it, probably because the replacement switch is not at factory settings and was refurbished? Please advise.

Hi @kaz

Greetings!!!

Thank you for your recent correspondence and update.

To answer and check your queries 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:

https://community.ruckuswireless.com/t5/RUCKUS-Lennar-Support-Knowledge/How-to-find-the-IP-Address-of-the-RUCKUS-Devices-Switch-and-APs/ta-p/77863

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:

https://community.ruckuswireless.com/t5/RUCKUS-Lennar-Support-Knowledge/How-to-access-the-Command-Line-Interface-CLI-of-the-RUCKUS-ICX/ta-p/74450

If you can access the Command line the prompt should look like 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.

Hi Imran,

When I scan, I see 4 devices listed as Ruckus Wireless (probably for the 3 access points and switch).

I tried ssh super@<IP> and admin@<IP> for all 4 IPs and none work. It just comes back with "Unable to negotiate with 192.168.0.150 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1"

I also tried nc <IP> 23 for all 4 and nothing happens. Like I said months ago when I received the device, I can't get into the system.

Hi @kaz

Greetings!!!

Thank you for the response and the information you shared.

Could you please try to access the Switch IP Address in a web browser?

You should see the Switch Dashboard as shown in the below screenshot to confirm it’s a Switch IP Address. Try to login.

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

Thank you again for your patience and understanding

Yes, when I put in the IP address of one of them into a web browser, it shows what you displayed with the ICX 7160-C12

Re: Switch problems (potentially)

kaz — Thu, 09 Apr 2026 03:52:47 GMT

I tried all the typical login/password combos and none of them work.

Re: Switch problems (potentially)

Hi @kaz

Greetings!

Thank you for your response and the update.

Please consider performing a factory reset on the RUCKUS ICX-7150-C12P Switch. Detailed instructions can be found in our RUCKUS Lennar Knowledge Base article and accompanying video:

Once done please try again with mentioned default credentials:
Username: super
Password: sp-admin

Please let me know how it goes.

I tried holding down the reset button for even up to a minute. Nothing ever flashes. The SYST stays orange and PWR stays green. After a couple minutes, it's up and running again.

But after that, I try all the typical login/password combos and nothing works.

Re: Switch problems (potentially)

kaz — Fri, 10 Apr 2026 02:34:43 GMT

Also, why do you keep insisting that the ISP should go in ports 1-12? When I do that, it either doesn't work or I get really slow throughput. If I put it into the C1 port, it works and I get hundreds of Mbps down and a hundred up. The C1 port is supposed to be the uplink port.

Re: Switch problems (potentially)

kaz — Fri, 10 Apr 2026 02:35:39 GMT

Maybe you need to just send me a switch that's already reset properly. None of the videos or explanations seem to be relevant to the switch you sent me.

Hi @kaz

Thank you for sharing the requested information on Private Chat.

Based on the troubleshooting performed, your ICX-7150-C12P Switch is not responding properly with the performed troubleshooting steps. A hard reset was also attempted; however, the issue still persists.

As a result, this Switch unit appears to be defective and needs to be replaced through the RMA (Return Merchandise Authorization) process.

To initiate the replacement, Please use the private chat option to respond so we can proceed further. For your reference, I have included a screenshot below.

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

Thank you again for your patience and understanding.

Hi @kaz,

Thank you for your response and the update.

Apologies, but we are unable to proceed with an RMA at this time, as your device was recently replaced. Replacement switches are shipped with factory default settings.

Based on the current status, the switch and Access Point LED indicators appear normal. We recommend performing a factory reset of the Access Points and reconfiguring them.

Please refer to the mentioned RUCKUS Lennar Knowledge Base self-help article for the factory reset process.

You keep asking me do things that don't work or aren't addressing the issue. Before telling me to do something, could you give me a reason why I should do this? Why would factory resetting the access points help if I'm simply having trouble logging into the switch? When the access points are disconnected, they have NOTHING to do with the switch at that point.
