I have two cameras DCS-930L and DCS-5020L.  The IP on both keeps changing several times per day causing disconnects from viewing and D-ViewCam.  When I go into network settings and change to static I lose connectivity to both.  This is on Windows 7 connecting to a wireless Motorola Surfboard cable modem and access point.

Camera: 192.168.0.177
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
Primary DNS Server: 192.168.0.1

Any help would be appreciated.

Added Google open DNS 8.8.8.8 and 8.8.4.4 and they connect now, but even when set to Static the IP's change causing a disconnect in D-ViewCam for both cameras.  Woke up with an IP conflict on my laptop.  

I've had this home network in place for a few years and never had problems with my other devices.  I use a ROKU, cell phone, PC, Laptop, and tablet on this network which allows up to 10 connections.

Rather than using Static IP addresses, I recommend reserving the IP addresses through your router. In fact, you should consider reserving the IP address (on your router) for all networked devices on your LAN to maintain consistency for applications that need to connect as well as mapped drives.

Thanks...  I'll try that tonight.  Next will be figuring out how to use the D-ViewCam software.  I have the .pdf manual, but still need help. Of course I'll save that for another thread.

Happy New Year!

You can consider this resolved.  Thanks again for your help.

##Edit##  IP on the 5020L changed again last night some time even when reserved on the router.  I've noticed that the 5020L is bay far more problematic than the 930L I have which stays connected and has never sent false motion alerts.  The 5020L also sends alerts when it changes from night to day.

I planned on buying more cameras, but so far out of two camera's I've called tech support 5 times and two weeks later I'm still having problems.  I think more documentation would be great since so much is left to the imagination or the hopes that the buyer is an IS wiz. 

I obviously have to get this IP issue resolved in order to use D-ViewCam software, or it's all a waste.

If an IP address is reserved on the router for the DCS-5020L, there are only a limited number of things that could cause the IP address not to stick:

• Make sure the DCS-5020L is set to DHCP in the web UI under SETUP > Network Setup > LAN Settings. Failing to do this can cause the IP address to change
  
• Make sure other devices do not have a static IP address set to the same value that's being reserved for the DCS-5020L. This can cause a conflict that can result in the camera dropping off the network
• Make sure the reserved IP address falls within the IP range established for your router. For example, if your router is using the IP range of 192.168.0.1 to 192.168.0.40, then a good IP address would be 192.168.0.10 (i.e. don't use 192.168.0.90)

It's always best practice to allow the router to perform the role of central IP management for all devices on your network to avoid potential conflicts.

DCS Network Cameras - Why Did My Camera IP Address Change?

I've checked those things and everything is correct.  I set my DCS-933L to 192.168.0.10 and the DCS-5020L to 192.168.0.20 last night.  The 5020L was 192.168.0.105 this morning.  I checked the router settings and .20 was no longer reserved, so I reserved .105 about 20 minutes ago. Only time will tell. 

The 5020L came on and recorded some fireworks last night, so at least I have the D-ViewCam configured correctly.  But it doesn't do any good if the camera disconnects due to IP change.  I recently returned a DCS-933L that sent false alerts all day long when it randomly changed from day to night even when there was no change in lighting and it was pointed at a blank wall. I tested it by facing it toward a lamp and turn it off and on.  It would send me an alert email each time.  I'm staring to wonder if this may be causing the IP to change somehow.  Losing confidence fast, but I would like to hang it out and get this working.

You can try a different IP address other than "20" to exclude the possibility of an unknown device or circumstance that's conflicting with the DCS-5020L. I own the DCS-5020L, DCS-931L, and DCS-932L and haven't had any IP address issues. Out of curiosity, what router make/model do you own?

All D-Link cameras with Night Mode will send an email alert during the transition between Day and Night Mode. That's a request that we've put in to have addressed. Many of the newer cameras and more recent firmware updates have added what the change logs call "[Bug Fix] Refine Day/Night mode switching judgment", which users have noted has reduced the frequency of false Day/Night transitions during subtle changes to lighting. The IP address flipping should not have any impact on email alert triggering or Day/Night mode transitioning, as these functions occur within the camera and are independent of network connectivity.

Lost you there for a while.  I tried cleaning up the routing table because one of my devices has an IP that is one letter and character off from another, or there was an incorrect entry.  One MAC ended in :B2 for the camera and another :B3.  Knowing me it was an entry error on my part.  So while trying to clean up I disabled some MACs, then I lost all Internet access.  Not the only thing working is the PC I have hardwired to the router.  I reset the router and added the MAC's back under Wireless access to Allow but still nothing is connecting.  

I have a Motorola Surfboard SBG6580.  I also reset wireless to defaults under the admin account, no go.

Should have added, I can connect to the wireless from other devices but not to the Internet.  I'm running the Motorola setup wizard now.

Wonderful way to spend the New Year.  Reinstalling fixed nothing.  The documentation has very little troubleshooting info, and Motorola support is closed today.  To make matters worse my wife can't watch her Korean drama which has me in hot Kimchee.

[drexellake]

OK I'm back up, but I had to add each wireless device manually by MAC to get them back.  No idea why.  I did find out I removed the WAN MAC, so that probably caused the disconnect.  Definitely a learning experience.  The only devices I'm going to make static are cameras.

I'm glad you solved the camera connectivity issues. I suggest you post your D-ViewCam questions on the appropriate board: D-ViewCam

Thanks again for helping.  I think I actually answered my own questions while working on the connectivity issues.  I'm still having issues connecting from Android devices, but I see another post with others having the same problems.  Happy New Year.

[drexellake]

Spoke too soon.  The 5020L disconnected again.  Taking it back to Best Buy tomorrow.  No way I should be spending this much time setting a camera up.

The 930L rarely disconnects, and when it does it's only for a couple seconds.  The 5020L disconnects and requires a wired connection to set up after it disconnects. Even had it reserved by MAC.  Never comes back on it's own.

Given what you describe, it sounds as though something may be wrong with the camera. If you have a physical store where you can swap-out your camera, then perhaps that would be the safest course of action. Post back and let us know how things work out!
