Connectivity Issues

[Bobisfa]

Hello,

I apologize in advance on my choice of tech verbiage as I am not a CPU wiz. 
I have read and followed many posts about this connectivity issue but couldn’t find anything on what I’m running into. I currently have an ICX7150-C12 with 2 R510 connected to a AT&T modem. 
When I connect to the system, my internet stalls out frequently so I always connect directly to the AT&T router to avoid this issue. Many of you have posted about this and suggested that I use a Putty Application to connect to the Ruckus switch to change a certain setting. 
I have done this but here is where it’s different for me. After logging in using the putty application, IP address and entering my user name and passcode, I am prompted with a “RKSCLI” and waiting my command. It also tells me that I’m in an Unleashed-managed mode. All the other posts show different including the actual name of the switch. When I attempt to enter the commands that are suggested, it doesn’t recognize it. 

Any help to steer me in the right direction would be much appreciated. Thank you.
