Hello! I purchased 3 node system to reach all the way to the back of my long apartment. Spent an hour on the phone setting everything up. Speeds are fast in the bedroom. However, my nest camera just will not show any live video. It does not say “offline” so it seems to be connected, but not able to do anything with the connection. I talked to Nest and they gave me 2 portnumbers to open. I have added these rules in both the Linksys app and my technicolor spectrum gateway. Still not working. Any ideas?
