I have been in my lennar home since 2019. I recently started having issues where items in our home would lose connection for a few seconds and reconnect. I decided to upgrade my modem/router from a netgear c7000v2 to a netgear cm3000 modem and Flint2 router. Now I can see my network but when I connect to it, it is extremely slow and most of the time the webpage won’t even load. My TVs won’t even stay connected. I’ve tried a bunch of reconfigs in the APs and the router but nothing has helped. I recently performed the firmware upgrade on my switch as well as I thought that might be the problem
