How to turn off Smart WiFI

I had to contact Optimum support. I contacted via chat. I asked if I could disable Smart WiFi. I was put on hold for about 40 minutes before I was transferred. After being transferred, I was told disabling Smart WiFi is not possible.Okay then... so I asked, "I have a device that can only connect to a 2.4 GHZ WiFi network. Do you have any tips for how to do this?"After a few minutes, the agent proposed that they could separate the 2.4 GHZ network from the 5 GHZ network. I said, "Great!" They did so after only a few minutes. This solved my exact problem! I now had two separate networks, one for 2.4GHZ and one for 5GHZ.And when I logged back into my router settings a few minutes later on my own, I noticed that there was a prompt to turn on Smart WiFi. I guess this means that it had been turned off inadvertently during the agent's process. It's kinda funny... they ARE able to turn off Smart WiFi, just not in those words. ask an agent to separate your 2.4 from your 5GHZ networks, because if you ask to disable Smart WiFi they'll tell you it's not possible except it is lol
