Stuff I ordered is definitely working better than my old stuff. Stronger signal as well. I picked up a Skybell HD and that is working as it's supposed to as well.
I saw this article today and it pertains to discussion in this thread. Basically you can have this company custom 3D print you a shield for your WiFi antenna that can direct, or shield, signal to where you need it. Once you receive the shield, you wrap it in aluminum foil.
