Impossible to speak to a person about a very specific question

I have tried xfinity assistant and I have tried calling the main service number.  All I need to know is whether my wifi is 2.4 GHz or 5 GHz and if it's 5 GHz I need to know how to split it and create a 2.4 GHz band so I can connect smart home devices.  Obviously the bot has no idea what I'm talking about because there is no prebuilt support for this that the AI recognizes.

I've seen other posts saying to "Direct Message" the customer support team but when I click on the DM icon, it just keeps opening one tab after another asking me to "log in" to my Comcast email (never done that), and if I click "Log in" it just opens up a new tab with the same exact page without log-in fields.

I am 7 months pregnant and have a simple question and don't have the patience for this whatsoever.  Such unnecessary stress.  I will switch services if it continues like this.
