Hi meowchi_16,
Are you able to find another device that is listed in the withelist?

Hi Admins,

I tried to connect all my gadgets that was recently connected to my router and good news, there's one phone that remains connected to my router. I was able to undo all the changes that I've made. They're all working now.

Thank you so much for your help and assistance.
