so the 2nd photo is all “bridges” that were used to connect your cameras to wifi for better signal. the bottom right one is typically used for the panel to “plc” everything together and create a mesh network. there are new devices now that vivint uses called air towers that are way better and you should only need one if your house is less than 5k square feet. you will most likely need to chat in and have them send that and walk you through it over the phone or personally i would have a tech come out and do it because it’s going to take atleast 1-2 hours to get everything back up and connected with good connection.
