Moved into this lennar home a few years ago and the Ruckus+WAP situation has recently been having some issues.
All of the ethernet cables run from the ruckus throughout the house to 2 WAPs and to 2 ethernet wall ports.
Both the WAPs and the ethernet wall ports drop signal randomly. For example, the ethernet port upstairs is what I use for my PC. It will get 500mbps most of the time but drop to 0 about every 90 seconds or so. I've defaulted to using the wifi connection from my router to run the whole house but this is less than ideal.
