Everyone,

I know this would be a long shot, but has anyone done a HARD reset (pressing the RESET button) after the firmware update and reconfigure the camera?
The reason for this process is firmwares sometimes have new drivers that must be apply on reboot... being that this model only have a Wireless interface, makes sense to keep the drivers updated, a hard reset forces a default reload of everything on the new firmware (a clean reload per se)

Let me know if anyone has tried it and please if you are NOT in the United States, stay in contact with your local D-Link Support Regional Office (by phone) since unfortunately they do NOT roam these forums.

Yes. I have tried, many times, doing a hard reset using the small pinhole at the back of the unit.

As concern the new camera I got today: It is not even possible to reach the web interface - that is quite obvious considering the very poor ping performance.

I will contact DLink and tell them what they sent is not working and claim another one.

Thanks for getting back to us... that's unfortunate  ,  this is the first 802.11AC camera D-Link puts on the market and so far my sample connected to my DIR-890L has shown no issues... my camera is connected about 40 ft. away from the router crossing two walls and I can get a HD quality picture using the mydlink Lite app and the mydlink portal, I have not yet updated to the 1.05 firmware, so I'll try today. 

I'm trusting that your regional D-Link office support guys can help with that... keep us posted.

If you can see the signal quality for the connected devices (fx the 935L) in your router/accespoint then try to keep an eye on that and at the same time pressing the "Site survey" in the web-interface of the 935L.

Hi!

Any progress?

I have the same disconnect problem with my DCS-935L after firmware upgrade to v1.05.01 through the mydlink Lite Android app. The camera never had this issue before the upgrade but now it disconnects very often. On the last disconnection I could see in the router's system log that it refreshed its IP (DHCP) between 07:21:47 and 09:33:51. After that only the other DCS-932L cameras refreshed their IP's.

The camera system log seems to be cleared on boot so I cannot see anything there.
I'm able to ping the camera, but not access it through the web admin interface. The mydlink Lite Android app lists it as offline.

I'm using:
Camera name: DCS-935L
Firmware Version: v1.05.01
Hardware version: A
Agent version: 2.0.19-b40
WiFi encryption: WPA2-PSK

Please, set to highest prio!

Is there a way to access it through SSH and fetch more debug logs (since it seems to respond to ping)?

Regards Mikael

I'm located in Sweden. Using a Dovado Pro router with the following WiFi settings:
- 802.11 b+g+n
- Auto channel
- Bandwith: 20Mhz
- 2nd Channel Data Rate: Auto
- SSID broadcasting
- Fragment Length: 2346

I also want to point out that I have used the same configuration for a very long time and had no issues before the firmware upgrade. My other three DCS-932L cameras does not have this issue. The cameras are close to the router.

Only other think you might try is to downgrade the FW on the 935L. Do a factory reset, load the v1.00WW FW manually using IE or FF thru the cameras web page, Let the FW apply, then do one more factory reset and set up from scratch. You need to have the camera LAN wired to the main host router and connect to the IP address the camera gets from the main host router. Use a LAN wired PC as well.
You can get v1.00WW and follow on version here:

Let us know if you see any improvements...

Just got my new USED camera from Dlink.

Same story: Very poor wireless performance:

There is something very very bad with this camera.

I have now spend so much time with this camera that I don’t know what to do.
To others: DO NOT BUY THIS CAMERA. I think DLink should remove the camera from the market.

I have downgraded to the latest (and old) firmware available at the D-Link support page, v1.03 b01, and the DCS-935L has been online since then (~ a day uptime).

Using a cable with DCS-935L? Are there such hardware versions with RJ45 connectors? My have only WiFi support.

Best regards Mikael

Let us know how v1.03 works for you.

I think I forgot that this model camera doesn't have RJ45 connector. Sorry.

Update:

I never managed to get the system (2 * 935l) working with my Dlink DIR605L. Fortunately, a new 1.05 firmware was released so I decided to try one last time with my Linksys-Cisco E3200 and luckily, everything works perfect now.

I have asked Dlink about what they have changed in 1.05 but they have not been able to answer that question.

Thanks for your help.

Sounds like this could be an issue with the DIR series router... I recommend talking to them about what your seeing and give them the information on the routers. IF one works and the other doesn't, possible the FW on the DIR series router needs to be reviewed...

I have the same problem with my new ipcam 935L, after firmware upgrade v1.05.01 the camera disconnect itself after some hours. I can ping the camera IP but can't access the cam  from the admin webpage or mydlink home app. My router is a Netgear DGN2200v4.

Any news or firmware upgrade?
 
If so I think I'll return it....

Hi! excuse me for non-presentation! I'm from Italy.
I have returned the cam...too bugs for me but I want to reply your questions:

What Mfr and model is the main host router?  Netgear DGN2200v4 (look at my post above...)
What wireless modes are you using? 2.4 Ghz
What is the distance between the Camera and the main host router? about 1,5 meters
Was a factory reset performed after the update then setup from scratch? yes

I can add that if I stop the Upnp service on the cam performing a manual forward of the ports on the router the cam announces again the standard ports 80 and 443.
I think there are some bugs in the firmware so I have returned the one I have bought.

Hi!

Firmware v1.03 has not the disconnect issue. I used it for a month and it did not disconnected. I recently saw that there was a new firmware release v1.06.02 so I updated the DCS-935L cam. But that version also has the disconnect issue. So it is definitely a firmware change after v1.03 that causes the DCS-935L to hang.

(I think I have noticed that the LED on the back of the camera is constantly on when it has frozen... When it's working it is blinking right?)

Is anyone at D-Link looking at this? Does it have a issue ID? Is there anyway for me to support you with the troubleshooting? I have worked with embedded network devices before so I can hopefully help you hunting this bug.

Best regards Mikael

Hi again!

Since the disconnect issue has not been seen in v1.03 but in the v1.05 and v1.06 (I have not tested v1.04) I started to watch the source code of the different releases. I saw that CONFIG_CPU_HAS_RADIAX was introduced in v1.04. Could the code related to that define affected the stability an maybe hang the system?

Can I get in touch with a firmware developer for this issue?

Best regards Mikael
