Hi!
I have also problems since upgrade to  v1.10.01... is more instable - the cam hangs at all and only a hard reset help to get it back working.
Since the ping was disabled by firmeware, I had to move on to http request to check if cam is still online. checking it whole day long, the cam is dieing, not every day, but often...

Anyone has also this problem? I think this must be a mem leak in webserver on the cam...
how can  I downgrade to old firmware version? where to download?

thanks, raimund

Link>Welcome!

  • 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 DHCP

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

Hi!

My DCS-935L keeps trying to connect to several outbound ip addresses for example 52.8.86.161, 54.193.41.31, 52.17.177.126, 54.169.242.162, 216.146.43.71. Is there a way to disable this?

What Mfr and model is the main host router?

Use www.domaintools.com whois look up tool to see where those IP addresses are going first:

Of of them points to Amazon:
NetRange:       52.0.0.0 - 52.31.255.255
CIDR:           52.0.0.0/11
NetName:        AT-88-Z
NetHandle:      NET-52-0-0-0-1
Parent:         NET52 (NET-52-0-0-0-0)
NetType:        Direct Allocation
OriginAS:       
Organization:   Amazon Technologies Inc. (AT-88-Z)

The first two are Amazon in California, the second two are Amazon in Ireland, and the last one is Dynamic Network Services Inc (DYN.com - DDNS service).

The Amazon IPs are most likely for the mydlink services.

The Netherlands

The first two are Amazon in California, the second two are Amazon in Ireland, and the last one is Dynamic Network Services Inc (DYN.com - DDNS service).

The Amazon IPs are most likely for the mydlink services.


DDNS was already disabled but still outbound connections to 216.146.43.71? That's weird. Any idea why this is happening? How can I disable the mydlink services?

Are you using or needing Mydlink services at all? If not then you can do a factory reset on the camera and just not set up mydlink features. This should stop all services from being accessed. I would remove the device from the mydlink service site as well.

Hi FurryNutz,

No.

Did that.

This should stop all services from being accessed.
No, still the same as you can see here:

I would remove the device from the mydlink service site as well.
Did that too.

Do you have any other ideas?

mydlink cameras will broadcast to mydlink servers regardless if you sign up for it or not.
