Would need to know your configuration and set up.
How many cameras do you have connected?
How is the DNR connected?
What mfr and model# router are you using?
How many other devices are connected to the wifi and what are they?
This was tricky to figure out but I also tracked it down. What's getting me still is the constant network activity; the device is reading the cameras nonstop although the cameras are set to motion detect only. Is it possible to use the camera's push on motion detect ability to only transmit when there is motion?? Otherwise it is killing my wifi to have this nonstop traffic! I had to unplug one camera to make wifi usable again.
I have two cameras, both are 932L, One camera is wired and one is using WiFi but I'd prefer to relocate the wired one to somewhere it would have to use WiFi.
The DNR is hooked up by LAN cable straight to the router, which is an Asus RT-N56U
Other devices on the WiFi are a couple of laptops, an iPad, and a couple of phones. A couple more computers and a printer are on the wired LAN. Nothing except the cameras stream nonstop.
I can tell its the cameras using up the WiFi bandwidth thanks to the router's network monitor.
Thanks for any help.
