Powerline verses Mesh extender
I'm trying to decide between adding an additional EX6400 mesh extender or a Powerline adapter.
First my setup...
I have a router (with the WiFi turned off) connected by Cat5 cable going to a Ubiquity Unifi WiFi End Point. The Ubiquity broadcasts the Wifi signal in my home. Because the wifi signal is not strong in the back of my home, I added the EX6400 Mesh extender. It has helped in one part of the house but I still and not getting a strong signal to two of my outdoor security cameras at the other end of my home. If I move the mesh extender closer to those two cameras, then the extender isn't always getting a good connection signal from the Ubiquity.
I'm now considering putting the mesh extender closer to the Ubuiquity End Point so that it gets a good strong signal and can provide good coverage at one of the home and then add the Netgear Poweline 1000mbps Wifi gigabit Essentials Edition so that I can place the wifi powerline adapter closer to the outside cameras at the other end of my home and hopefully get a better signal to them. (By the way, if you have a better Power Line product that I should consider, that would be helpful.)
My thinking is that if I connect the Powerline adapter to my router and then place the Powerline wifi adapter closer to the two outside security cameras, that the wifi signal from the wifi Powerline adapter product would provide a stronger and more consistent wifi signal than relying on the wifi signal from the Ubiquity then to a mesh extender and then on to the security cameras.
My question is...Will adding the Powerline product give me a stronger and more stable wifi signal then a second mesh extender if I set it up as I described above?
