I have been getting this message for the last few weeks, every minute or so.
Windows--System Error
There is an IP address conflict with another system on the network
I read online how to handle it--you reset the IP from the command prompt, but this has happened continually, not just one or two times.
Is there a setting with the router (DIR-655) that I can tweak to eliminate this? I have updated the latest firmware about a week ago and the problem still continues.
I am running a desktop and a laptop from the router, both Windows XP.

Have you tried reserving the IP's so that the computers always get the same IP from the router?
Setup > Network Setting > Add DHCP Reservation
-
Try reserving the IP addresses for your desktop and laptop on the Setup>Network page of the router. This will make the desktop gets its address everytime and the laptop get its own everytime. If you still get that error you will have to check on your Status Page what addresses the Router is giving out and the machine it is giving it to.
-
OK I can do that--that sounds good.
(1) Is there a given range for the IPs I select?
(2) And this will not interfere with any other wireless networking, will it, because I take the laptop to other places and connect to their networks as well.

Hi prr,
All computers that are hooked up to your Router, via Ethernet Cable or Wirelessly, should make sure that in the Properties for the Internet Protocol (TCP/IP) attached to the Adapter of your Local Area Connection or Wireless Network Connection, that it doesn't have any IP Addresses assigned to it.

In neither properties dialog (for my laptop nor for the desktop), is teh TCPIP setting provided with and IP. For both computers, the setting is set to have the IP assigned automatically.
Now I gotta ask--were you, in a way, saying that I SHOULDN'T have the D-Link router assign specific IPs to these two computers? Or was this TCP-IP setting simply one more thing to check and make sure?

Windows--System Error

What other devices are on the Network?
Are you monitoring your Network with Software like Network Magic?
You need this type of Software to find the problem.
-
If you do a reservation for your systems there will be a less likely chance of getting a conflict. If after doing the reservation you still see an IP conflict then more troubleshooting will be necessary.
-
OK, I can insert the IP address in the reservation section.
(1) Do I just copy the PC mac address?
(2) what IP do I use? What range of numbers can I pick from?

On the network (no software monitoring it at all), I have these two computers, the router, and a printer that is shared (which I can access wirelessly). FWIW, I also have the internet signal fed into another router, which is used to give me VOIP on the phone lines throughout the house.

The easiest way is to go to the Setup>Network Settings page. At the very bottom you will see the machines that are getting an IP address from the Router. Click the Reserve link next to your unit and it will fill the information out for you in the DHCP Reservation section. Make sure the Enbale button is checked and then hit the save button that is in the DHCP Reservation box. You will then see the information added to the Reservation List.

Hi prr,
Is the printer, a Wireless Printer, connected to the Router, wirelessly, or is the printer plugged into a Wireless Computer?
Did you create a Static IP Address on the Wireless Printer, when you first set up the Printer?
Did you have to create a Static IP Address for the VOIP Device, when you first installed it?
THe problem is that maybe you did and don't remember it, so when the Router assigns its Dynamic IP Addresses, you have a conflict, when it matches the Static IP Address on that device.

OK just did that. I'll see how that goes and report back. Thanks.

The printer is wired, but shared, and connected to the desktop. Through the laptop, I connect to it via my wireless router (the DIR-655). I don't recall what I did to set up the VOIP (an old Linksys router).
I want to see if the reservation idea will take care of the problem first, though.

Do I need to do the same for the desktop--or just my laptop? I just did it for my laptop.

Hi prr,
If you are going Static IP Addresses for all, you don't do it from a Wireless Connection, but from a Wired Connection. From a Wired Connection, you can see all devices connected to the Router.

You don't clone any Mac Addresses.
Under Add DHCP Reservation, click on the Down Arrow for all Devices that the Router sees.
-
OK I've done this for my laptop (wireless) and my desktop (wired). I do have one more question.
You said that I should do this for all devices taht the router sees. There are 5 more IP addresses listed. I have a printer (wired) that is probably seen here, and perhaps that old Linksys router that is also hooked up to the DIR-655. But I honestly have no idea what the other three are. I typed in the IP address and just got a timeout.
(1) do I need to reserve for these others?
(2) I just read that you said I can't clone MAC addresses. Does that mean, for those addiitional devices (not the two computers), I do NOT select the "copy computer's MAC address" option?
Sorry for asking so many questions but networking is reallly not my thing.

Hi prr,
Don't use the Clone MAC Address.
However, since you don't know Networking, start over.
Do a Factory Reset. Hold the Factory Reset button in for 20~30 seconds and release.
The Wireless devices won't be able to reconnect, until you reenter the SSID Signal Name and Passphase for Security, using a Wired Computer.
By doing a Factory Reset, it won't remember the old devices, just the current devices that the Router currently sees.
It means more work, but the result should be worthwhile.
-
Well since I updated the IP addresses I haven't been able to get online. I went ahead and reset the router to factory conditions, reinstated my password, but still can't get online (wirelessly). I can get online over the wired desktop.
I re-uploaded the firmware (same version as last time--the latest 1.33NA or 34NA). I rebooted the device. I swapped those antenna, still no wireless internet.
Can someone help me out here? I paid a bit of cash for this router b/c I was told it was a high-quality one. I'm hoping that after a year or two this thing hasn't become a piece of junk.
-
Never mind. I had established the password to get in to the router itself, which was the same as my network key (the password I type in to get onto the wireless connection). After re-setting the router to factory settings, I forgot that it gave me a new 834-character-long password to use (until I changed it back). OK
well I'm going to see if just re-setting factory conditions is enough to keep that IP address conflict away. If not, then I'll go back to reserving the IP addresses. Thanks for the help.
BTW--I was wondering---anytime I get a problem with the router, is factory re-set a good idea? Kind of like re-installing windows when it gets slow? I have the router settings saved in that file that they create for you, although its not like I do a lot of tweaking anyways....

Hi prr,
Note: When you do a Factory Reset, it is starting completely from scratch. That includes resetting the Password to blank. So to gain access, you simply hit enter. Admin is already filled in.
Once you get the Router set up to your liking, save its Configuration File to your Desktop Briefcase, to find it easier later.
So the next time, you do the Factory Reset, all the tweaks and changes you made, can be restored by simply uploading the file to the Router.
Anytime you change the Password to get into the Router, it would be a good idea to save the new Configuration File.
By the way, until you set up again the Wireless Section, to what it had been, you won't be able to log in wirelessly. I believe I already said this.

Yes you did, but I didn't realize that a new key was generated for me that replaced the old one. I tried entering (from my laptop) the old key that I had used all along, and of course it never worked, as I had to use that newly-generated one first, and then I changed it.
Is re-setting to factory config a good way to troubleshoot? It sure has seemed to resolve the IP problem, as I have been online several times throughout the day and I haven't yet gotten a message about an IP conflict yet.

Hi prr,
Yes, resetting the Router, is not a good way to troubleshoot, but is a very good way to fix connection problems. Especially useful in fixing corrupted instructions in the Router caused by Power Failures.
-
OK, that's some food for thought. Connection problems-yes. I can handle that one.
Thanks to you and everyone else who chimed in here.
After I stopped using SharePort to hook up with my printer (I simply now share it from the desktop), I've had no problems with this router, and look forward to quite a bit more use out of it. Thanks again.
