Okay. So I answered my own question. After racking my brain on this for days, buying a new RF extender, loading software, playing with the configurations, searching for interference (baby monitor off)and anything else I could think of trying...I figured it out. My neighbor has a new baby at home too. My monitor, no problems...Their monitor = major interference. I guess I should buy them a new monitor like mine. Hopefully this will help someone who stumbles onto this post like I did.
