I have a nice router even though it’s 9 years old. I get 1200mb/s DL speeds.
So when I get the RSSI @ 53. I still get great results. So I do t know what kind of router you have but you might need an upgrade. Also. Live View might be affected by their (Ring) servers as well. Just as long as your recording properly and can go back and view past events. You’re fine.
