Train, so I have setup the IP cameras (WIFI). When I installed one, it worked fine. I was able to monitor remotely through phone. However, as soon as I two more cameras, pictures freeze frame ever two seconds.

I read that each cameras take up 4 Mbps. I believe the router and ISP provide 54 Mbps. I read on another forum that I need to put these cameras on a switch to control the upload speed. Can you help me understand or make recommendation?

Thank You
