Xfinity wifi not in list of available networks

Hello,

My issue is related to another post titled “wifi not showing up” dated 6/11/20. As of 2-3 months ago, I was able to see Xfinity Wifi in my available networks on desktop, laptop, and phone. Now for some reason it’s only visible on my phone.

I saw a reply from jesslaura on 7/8/20 that advised to change the 2.4 GHz wifi connection settings from 802.11 g/n/ax to 802.11 g/n or vice versa. Problem is I can’t find these settings in my xfinity account. Xfinity tech support had no idea where to find it, which really surprised me.

A screenshot of my internet account settings is attached. Is it possible to advise how I make this update from the info provided? Any help would be greatly appreciated.
