DCS-935L Won't Connect to WiFi
« on: March 28, 2016, 03:48:22 PM »

Been loving my three D-Link cameras, unfortunately one of them has developed a problem.

Last week while out of town I could not connect to my DCS-935L, my two DCS-932L cameras were/are working just fine.

When I got home I power cycled the DCS-935L
The LED on back stays red
I reset the camera and deleted it from my MyDlink account

When the camera reboots I am able to connect to the camera locally via the QRC.
I see my home wifi and can enter my password
The DCS-935L LED blinks from green to red and never goes back to green.

I've reset the camera several times and know my wifi password is being typed in correctly.
I am fairly confident the camera's wifi is working as I can connect via my iPhone/QRC and see my home wifi.

Any suggestions?...

Link>Welcome!

  • What Hardware version is your DCS? Look at the sticker behind or under the camera.
  • Link>What Firmware version is currently loaded? Found on the DCSs web page under status.
  • What region are you located?

What Mfr and model is the main host router?
What wireless modes are you using?
What is the distance between the Camera and the main host router?
How many other wireless devices do you have connected to the main host router?
  • Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
  • Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner to find out. How many?

I recommend setting a static IP address ON the cameras outside of the main host routers default DHCP IP address pool as a troubleshooting step: 192.168.#.93 or .35  DHCP

Test cameras with uPnP and uPnP Port Forwarding both enabled on ALL cameras: DCS Cloud (L) Series Camera Configuration and Mydlink.com

I have two of these. What works best is assigning a fixed static  address under camera  network and then reboot the router. You won't have any more issues. You are seeing ip adrdess conflicts likely  that turn on and off  like phones and laptops .  It's a timing assignment issue with dhcp server and reserved addresses with other devices on network . Camera is remembering it's assignment but router not reassigning since it already gave that number to another device. Make sure you use channel 6 on router. Every other channel seems to interfere with camera signals as well

Is uPnP Port Forwarding enabled on your cameras?
What Mfr and model# is your main host router?
Channels 1, 6 or 11 or 13 if your out side of the NA region are valid channels to use, however it depends on there use by your near by neighbors whom might have wifi using those channels. Scan first to see what channels being used first.
