Linksys Wireless Router :: IP Address Conflict Using Wrvs4400n?
Jan 24, 2013
I get a "IP address conflict" message on my wireless network. Using a WRVS4400n wireless router with the latest firmware that is set to PPoE. Motorola 336 dsl modem is set to bridge mode. My network has 2 computers attached: hardwire desktop and wireless connection to laptop. When I contacted ATT support, they said the problem is in the wireless modem. Are there some settings in the WRVS4400n that must be set to insure that each computer gets a different IP address?

I've been keeping an eye on my IPS report tab lately and have been watching a large number of ICMP_SMURF and DOS attacks originating from chinese ip address's. I know I can probably block the offending ip's through the ip based acl tab in the firewall settings, but I'm kind of a newbie how I can block certain ip's from touching my router?

I have a Netgear WNR612 wireless router, which worked fine for a few weeks. Then something happened and I can't keep the connection anymore. It happened right after I used iTunes to update my iPhone, perhaps a coincidence, but I'm mentioning that just in case. Internet still works fine with ethernet cable straight from the computer, only the wireless connection doesn't work. This happened about a month ago and I haven't been at home much to fix the problem. I have turned off and unplugged everything for several days at a time while gone. I get a Network Error message saying, Windows has detected an IP address conflict. I have tried restoring the router back to factory settings and reinstalling the wireless card. I have tried changing the IP address settings both in the Network and Sharing Center and the router admin page. What I think I should do is change the IP address in Command Prompt, but when I type "ipconfig /release", it says "No operation can be performed on Wireless Network Connection 2 while it has its media disconnected" and the same for Local Area Connection. I don't understand what this means, because there is a wireless key in my keyboard and there is a white light (not orange) like there should be. Also in the Network and Sharing Center, I can see that the connections are enabled.

My neighbour n myself are using a shared internet connection. The modem is situated in his house and I have connected to that modem using a LAN cable, which comes to my house. That LAN cable goes into my WiFi router (through which I use the internet connection). I use a Lap and my neighbour a Desktop, he's receiving a "IP address conflict error" in his system, due to which his internet connection is getting disrupted. If I don't use my Wifi router and connect directly through the LAN cable he does not face any problem. But I need my router back?

I have a Netgear DG834PN Router. Connected to it usually are 2-3 laptops (XP, Vista, 7) wirelessly, a Xbox 360 and Win 7 PC via cables, a wireless printer and often an iPod touch, however PS3s, mobile phones etc are connected occasionally.
It had been functionally normally.until we changed ISP after ours was taken over (we didn't change but the provider obviously now has). However, since then (1st Feb) we've been having connection issues, probably an IP address conflict where items can access the router but not the internet.
The iPod and Xbox sometimes don't connect, as do the laptops often after been powered up from a sleep. Yesterday, when powering up one of the laptops, I got an IP address conflict message. Restarting the router sometimes works, but mostly it allows one device on and not another.
The printer has a static IP address (192.168.0.4) that I had to set up to get it working, but this has been active for months now without issue. I've had a look in the router settings and it's set up for DHCP as default with IP addresses from 192.168.0.2 to 192.168.0.254 so I don't understand why it has this issue suddenly. I had a look at the connected devices list, and everything appeared to have its own IP address.

When I sign on the internet, I get a Windows System Error - "There is an IP address conflict with another system on the network." I went to command prompt and typed "ipconfig /renew" but the response was "No operation can be performed on Local Area Connection while it has media disconnected".

Nothing seems to be able to connect to my wireless network. It seems to have occurred after I installed a new copy of windows 7 onto my sister's desktop. A message appeared saying we have the same ip address. I've tried renewing our ip address on both desktop but it won't give us new ip address for some reason.

I have just got viasat internet from England to replace the local internet here in Spain. I believe that My router was programmed to the old internet and wont recognize my new modem. I have tried live chat and got guided thru a few things and established an IP conflict, but lost contact before we found a solution.

I've got a wireless network, consisting of two Windows 7 PCs, a wireless printer, an Android tablet and an iPhone. The PCs are always on the network; the other devices only connect occasionally. The router is a Dynamode R-ADSL-C4-W-G1. IP addresses are assigned by DHCP, and both PCs are set up to get an IP address automatically.Now and again, I get an error message on my PC, saying Windows has detected an IP address conflict on the network. I looked in the System Event Log, and found the following message: Quote:The system detected an address conflict for IP address 10.0.0.3 with the system having network hardware address [hex number here]. Network operations on this system may be disrupted as a result.
When I checked in the router settings, I found 10.0.0.3 had been assigned to the other PC, which also has the hardware address given in the error message - I'm not sure how that constitutes a conflict!When I get this error message, I never encounter any connectivity problems - i.e. both machines can still access the internet.

I've been getting a popup error message for about a week:"There is an ip address conflict with aother system on the network". This is only for 2 desktop PCs with wired ethernet connections. Wireless devices are fine with no error message. The wired LAN PCs basically lose all network capability. Reboot fixed it, but it returned every time it was rebooted.I have a Virgin Media Superhub with another router configured as an access point. To cut a long story short, after trying to reset everything, re-installing network adapters & swapping ports, I decided to set the Superhub to Modem Mode, and re-configure the access point router to act as a standard wireless router. In other words renewing the whole network's LAN IP addresses.I now don't lose network capability, but the error message is still appearing on both wired LAN PCs. I use the Fing app on my android phone which lists IP addresses for all devices on the network, wired and wifi, and no 2 addresses are the same, which suggests that DNS is doing its job.

I have been having router/wireless internet issues since my internet provider had to come out and fix the outside lines. Ever since then I get the Network Error: "Windows has detected and IP address conflict" whenever my laptop and my wife's try to use the wireless at the same time. I have tried release/renew of my IP address and also reseting my router to factory settings to no avail.

There are about 3 laptops, one desktop, and 2 gaming consoles that are using the router. Everything connects fine expect the one laptop. It is an ASUS laptop running Windows 7. Whenever the laptop is going to connect to the internet every other device using the internet is stalled for a few moments, then reconnects. The computers then give the IP Address Conflict message. This is extremely frustrating. Sometimes it happens when people are accessing the Web for college assignments, and sometimes gaming, which is annoying to get disconnected from. I have tried to release / renew the IP, but it tells me it can't complete the process.

I have a laptop running xp on a home network using cisco-linksys wrt310n router. A couple months ago I added another laptop running win7 to the network, and since then I have been getting ip address conflict errors once or twice a day. Both machines are set to obtain ip address automatically

here where I work we are having an issue with IP Address conflicts. We are not sure exactly why, though. We have only had it happen 2-3 times so far, but this has been over the past week or so, and we would like to get it resolved. Here is what is happening: Last week we were getting an "IP Address conflict" message on one of our computers. It had received 192.168.3.112 from our DCHP server, so we switched it to a static IP address up beyond our DHCP range. We then tried pinging the address with the conflict, but got nothing. We figured it was some device that had a static address, so on the DHCP server we reserved it to a non-existent mac address so it wouldn't hand that one out again. This wasn't a problem, since it was an isolated incident.
Since then we have tried periodically pinging 192.168.3.112 to see if there is actually a device using that address, but have gotten no replies. Since then we have had another one or two times where this has happened, but with different IP addresses. We went around and checked a couple of different wireless routers that we had deployed, but the DHCP had been disabled on all of them (but then again, the issue came up just recently, while the routers have been out there for months).

I have recently started getting random 'Windows System Error- There is an IP conflict' blah blah blah messages on my PC, this only seems to happen when I also have the wireless switched on on my HTC Desire phone.I have done the usual checks and everything in the house, that is connecting to the wireless (2 phones and a laptop) is on a different IP address so as far as I can see there is no actual conflict.I have a Netgear WPN824v2 Router with the main PC connected to it. Sometimes it goes for ages without doing it or I can get one after the other, sometimes the PC drops it's internet connection altogether.

This has been happening for a few months and I have had to reset the router every time and it usually works. I have 3 laptops, normally 2 are used and a roku streaming player connected to the tv. Both laptops are on windows 7 and sometimes the wifi suddenly stops working [sometimes only stops for some devices] even though i am still connected to the my router. Some times, a popup comes up that says that windows has detected an ip address conflict, so I think that that is the problem, but when I try to do ip/release, renew, it says that the media is disconnected to wireless network connection 2 even while i can access the internet.

I have a conflict with my satellite Internet connection between the modem and router IP addresses. I also somehow entered a password for the router which I now cannot duplicate. received a request for additional information which I responded to in September. I attempted to follow-up in October again, but I have not received any reply since the first one on August 11, 2011.

I have switch 2960 and router that connect with one interface to that switch. the link is trunk and Router function is inter vlan routing between 4 vlan. This netwrok has only one ip address space that is 10.10.2.0/24 and work without problem. We connect cisco switch 2960 with optic link to another switch that in stack 3750 which configured as trunk link and allowed only 3 vlan between them. In the other side netwrok which consist the switch 3750 we have different subnet ip address that switch working in layer 3 too. the problem is that when I permit vlan 210 in the switch 2960 only layer 2 between this switch and the 3750 in network that consist th ip address 10.10.2.0/24 devices, if I disconnect and then connect pc to network he says that he has ip conflict and in the log he show mac address of router that has vlan 210 subinterface configured with 10.10.2./24 subnet. But how I gibe back vlan 210 from permited vlan in trunk devices start normaly working. If I again put vlan 210 to permit vlan in that trunk devices again said that there are conflict ip address and show mac address vlan 210 router subinterface.

I recently changed my home configuration. I have AT&T DSL and I replaced my 2WIRE gateway with an AT&T provided Motorola Modem and a Linksys E2500 router on Sunday. For the last few days, all has been good. Last night and this morning, one of the computers in the house began getting IP conflict messages. The computer is provided by my company and uses the Cisco VPN client. I am not sure if it is conflicting because of the VPN (only seems to happen when it's connected) or with one of the other devices on the network (i have four other computers, a game system, and a few phones on the network).
Is there a way to prevent a conflict from happening again? My work requires me to have a constant connection for days at a time and these IP conflicts are causing constant headaches. Would creating a static IP address on the work computer outside of the DHCP range clear this up?

My WRVS4400N, V2.0.2.1CPU:STAR 9202.Doesn't allocate IP address on DHCP for anything but the Open SSID. All others, WEP, WPA, WPA2, nothing.I tried different clients, Intel Centrino wifi, Cisco, AG-CB21 same results.The config is std, I tried one VLAN for ALL SSID, I tried different VLANS, same.

I would like to connect to the built in accounts on the wrvs4400n from a mac VPN client. I am new VPN and have not found much information on how to establish this connection. Since Linksys seems determined to rely on Quickvpn, and provides no information on what it is actually doing under the hood I can not figure out how to configure any of the VPN clients available, or the built in VPN tools, for OS X (10.4.8). The only information I have been able to find seems to relate to setting up VPN Tunnels, or running a server behind the wrvs4400n and using one of the VPN passthrough options. I would like to connect directly to the built in accounts, how to set this up on a mac?

I recently purchased and installed seven WAP300N access points in a school, but they are now having intermittent problems with network access, as of right now their network is completely unusable. Specifically there appears to be a conflict between these access points and the gateway/router which provides their network clients with addresses via DHCP; BUT in the three years I have been assisting them the DHCP server on their Cisco router has never before given any problems!
All WAP300N units are wired to the network acting as standard access points and setup to pickup their address automatically via DHCP. When the problem first arose I changed to offending unit to use a static IP address to avoid what I presumed was an address conflict; however the same problem now appears to be happening with the other units as well!
My understanding is that these WAP300N units do not have any in-built DHCP server capability, is this correct ?If not, how I can disable this feature.Otherwise, it would seem to me that the units must be incorrectly using the default gateway address which they are getting from the DHCP server as thier own IP address. Unfortunately assigning static IPs to each access point is not possible as these are controlled by another group and the existing allocation is now used up.

I would like to automatically check if the VPN is up or down, simple enough, and respond by bumping it, disconnecting and connecting, as needs be (not so simple I think).This through a C# program using HttpWebRequest and HttpWebResponse.It's simple enough to login to the VPN page using known credentials. Done deal. And also very easy to check a couple of known patterns in the VPN table.When I determine I need to bump the VPN, how do we simulate the form submission and/or call to the JavaScript programmatically? we're using a Linksys WRVS4400N router, firmware version V1.1.13.

I cant get the WRVS4400N to connect to my cable modem. The WAN link light isnt even lighting up. Im wondering if this unit is bad out of the box. Is there a setting im missing to get them to talk to one another. This is no mention in any of the manuals.
Connections: - The "Internet" port on the WRVS4400N to the "Network" port on my cable modem (No link light)
Here is what i have verified at this point: - My old router connects instantly to the modem when plugged in (Same cable) - When i plug my laptop into the WAN port on the WRVS4400N i get a link light. When i plug the modem into the WAN port...nothing.

I have a WRVS4400N setup as a main router for one of our bays. For wired connections it is working with no problems. When I first installed it it ran fine for wireless as well. I was trying to get WDS to work and at some point the wireless stopped working. My laptop can no longer connect to it and often cannot see it when doing a scan for networks. I have already checked that it isn't a problem with the laptop, that there are not other networks causing interferance, and even tried resetting to default configs.
