Network Multiple Routers - IP Conflict?
Mar 7, 2011
I have two Netgear routers (N150 and DG834) and want to set them up so that in my office (external to the house) I have wired internet connection and in the house wireless, the office is too far away to run the wireless for the house there. The router in the office is connected to the ADSL line with the router in the house connected to it via a network cable.?I have disabled wireless on the office router however when i try to run both routers together I get an IP Address Conflict, I know I need to change the IP address so that they don't conflict but when I have tried this it hasn't worked and I have had to reset the router to the able to access it.

I want the following configuration:
- 1 Master router with no PC's connected (only the slave routers will connect to it)
- 2 Slave routers each connected to master router Each slave router will have multiple PC's connected via ethernet and/or wireless
I have been able to set this up with all PC's having an internet connection. BUT I need all the PC's to see each other on a single network. I can see all the PC's on a single slave router but I can't see the PC's on slave 1 from slave 2 or vice versa. I have been using the WAN inputs on both slave routers. All 3 routers are Netgear WRN3500L.

I have a 2 wire HomePortal 1000SW modem in our home office. Its connected to a dlink DI-524 wireless router (also in the office), which is connected to a dlink DIR-601 in the opposite end of the house, both are connected using LAN ports, not WAN. All 3 of these devices are capable of wireless, and all have the same SSID and wep encryption key (they use different channels, 1, 6, 11). As of right now, i have the DI-524's wireless disabled, and the wireless is still on for the DIR-601 and the HomePortal, but only the HomePortal has DHCP turned on. The problem I'm having is that i can connect and get assigned an ip address when I'm in the office, but if i initially connect to the network near the DIR-601, i get limited connectivity and a self-assigned IP-address.

I recently got a new modem/router device from my ISP and its wifi is fairly weak (no external antennas) especially in my basement. Since wifi is no longer an option and I only have one ethernet connection to my basement I was thinking of using my old router to distribute the one ethernet connection to multiple devices. Connecting my one ethernet connection to the old router, and its port#1 to my PC in the basement works without any meddling, but the speed has taken a significant hit. Before the second router I was getting ~30-40Mbps from my ISP. With the second router it is reduced to ~10-20Mbps. Both routers I assume are capable of at least 100Mbps (probably even 1Gbps?). The older router is a Linksys WRT54G which can do 54Mbps wirelessly so I assume it can exceed 10-20 wired.I tried giving the second router a static IP with DHCP off, but it did not seem to make a difference. I don't know if I set it up correctly, however. The modem/router uses 192.168.0.xxx while the second uses 192. 168. 1.xxx so I do not think there is any conflicts in the DHCP.

They have a NETGEAR ProSafe VPN Firewall FVX538 on 192.168.1.1. They have 2 different wi-fi routers, one is static at 192.168.1.4, the other is not static.Someone donated a Linksys Wireless-B Broadband Router. They asked me to set that up. But i cannot get to the home page to change the IP address. 'multiple routers' it says to simply unplug one, so you can get to the config page at 192.168.1.1. I can not unplug the main router for the business, right? Do i need to change the IP of the Netgear temporarily? Will that bring down the network?

Can an IP conflict cause network issues for computers other than the devices that have the same IP? I have resolved an issue where someone was testing a device on our network and assigned a static IP that was already in use by one of our printers. Specifically, I am curious if the IP conflict could have caused issues with mapped network drives for other computers. I just seemed to have network gremlins for the 2 days of the IP conflict.

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 am dealing with three office networks, all three have the same conflict. The error messages I get all say there are two devices assigning ip addresses. As soon as I get the computers communicating with each other, two seem to crash overnight, I suspect due to the conflict. Here is the rundown on the networks. All are windows networks - the problem I am having is file sharing mostly and printing.
Network A: server OS is XP Pro - SP3, four workstations, XP Pro-SP3, Windstream DSL and Netgear Router. I have already bridged the router on this one, and it did not correct the conflict.
Network B: Server OS - Windows7 SP1, three workstations all XP Pro SP3, ISP is Clear (formerly clearwire). Router is the old wired Linksys befsr41 v4.
Network C: server OS - XP Pro SP2, ISP - Clear, three workstations - two are XP ProSP3 one is XP Pro SP2. I have had less trouble with this network, but I suspect the conflict exists here as well.
I have tried to get a static IP address from Windstream where I have had my worst problems, but cannot seem to get one. I suspect we have the least expensive service option possible, and are possibly using a service designed for home use as opposed to business, as someone told me recently that getting a static IP address can be expensive. Is this true? Currently all networks have DHCP enabled, and the routers are set up to use DHCP. My thoughts were to disable DHCP and assign ip addresses manually.

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 a Belkin N Wireless Router Model F5D8236, which has served my laptop with wireless and my wifes desktop computer through a ethernet cable for the last year.Recently we had to move her computer to another room so I got a Usb Wireless adapterNow when I try to connect her desktop to the network it says the settings do not match, or when prompeted for the PSK, it says its wrong, even though I'm dead sure I put it in right.I've tried transferring a copy of the settings with a flash drive, I tried resetting the router a dozen times, and all the wp2 settings.The USB adapter works, because when I turn the security feature off on the router, suddenly it can connect to the network.

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.

Is it possible to daisy chain 3 switches and not have ip conflict? I am running a public access network for a library. For certain library software I need for all workstations to see each other. I have 25 workstations in total and two separate management consoles. I have all workstations on two switches but one of the management consoles is on the third switch because when joined with the others it has an ip conflict. I need this console for the digital sender that is connected as well as to act as a server for go print software.

I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.

I have 2 internet connections in my office one via Verizon Fios and another one via the local cable company. On the fios connection I have an RV042 VPN router and on the Cable company connection I have an rvs4000 router, I would like to know if there is a way I can connect the 2 so I can share a printer I have on one of the 2 networks from the other network without using the VPN feature, like via an ethernet cable connected between the 2 and some kind of static route maybe?

In my office we have concrete walls and very limited wiring. The way it is set up is we have a Verizon DSL Modem that comes in then I have a router with it that splits the signal to 4 other routers that each split the signal 2 to 3 more times. I have to use routers so that it assigns IP addresses.I bought a new D-Line N300 Wireless router with USB imput. I want to attach my Home Media Network Hard Drive Cloud edition to the 1st router (attached to the modem) and then share the data off that hard drive with everyone connected to the sub routers.

I have a job with a budget-limited client who has three Cisco RV042 dual-WAN routers. They had hoped to establish rather seamless *inbound* service, which doesn't seem to be the real purpose for these units, they appear to be designed for bandwidth aggregation and/or rather seamless *outbound* service.Since they have three of these routers, and three broadband connections (two different 5 IP blocks at one ISP, one 5 IP block at a second ISP) I am toying with the idea of using one router per broadband, and configuring each router for One-to-One NAT, dispensing with the dual-WAN redundancy feature.Each router will come from a different public subnet, yet have a one-to-one NAT to the *same* internal server, for instance:
Router 1 - 74.92.X.X ---> NAT ---> 192.168.1.100
Router 2 - 67.78.X.X ---> NAT ---> 192.168.1.100
Router 3 - 97.76.X.X ---> NAT ---> 192.168.1.100
The routers will be configured on the same subnet internally. 192.168.1.1, 192.168.1.2, and 192.168.1.3 respectively. I'll use weighted multiple default gateways on the server's IP configuration, to establish their default and failover gateways.My question is, does configuring multiple routers for one-to-one NAT to the *same* server cause any conflict or failure? You know, of the "sorry bub that private interface is already sucked up by router 1 and I can't do this" nature?

wireless networking in their home. Their home is built of bricks (inside walls and outside), so basically going about 10 feet around a wall will drop a wireless signal.One problem is that the router outside in the office has a separate network than the router inside of the house by the kitchen. They're both configured to use different SSIDs/encryption keys, etc, but they both are connected via ethernet cable. Problem is, moving from one side of the house, she has to switch her tablet/iPhone to the network being broadcasted by the first router, and then vice versa when going around the second wireless network.
Can I just simply configure the router inside as a wireless bridge and use the exact same SSID/encryption etc and have only one network show up regardless of which one she's closest to?I basically want to set up her network to where she just needs one wireless network, and no matter where she go in her house, she's connected to the same network (regardless of which router it's connected to), and still have internet access.

I was actually looking forward to setup multiple routers at our college(I know its quite late) where we have quite a good network of ethernet cables. Also, almost every cluster/lab has its own switch and we use static IPs with proxy to one network address(192.168.130.2). The user should be able to travel across multiple ROUTER/AP zones without changing connections.
all I got was I have to do something with MAC cloning and SSIDs.

I have an upstairs office where my desktop pc is located. This pc is connected to the internet via a Linksys Router in my bedroom...
My XBox is downstairs and connected wirelessly to a Belkin Router downstairs. The Belkin Router is then connected to my Linksys Router to access the internet.
I can access XBox Live and the internet through both the XBox and my pc BUT the XBox doesn't see the computer on the network.. so I'm unable to stream files from my pc to the Xbox.
I'm attempting to stream movies from TVersity to my XBox but my XBox can't see my pc..

I am trying to access home security camera from outslide my house.I have an AT&T internet coming into the house. They have a router that comes into the house and that splits off to another router in my house which carriers CAT5 all over the house. One of the wires go to another router that I use for my wireless devices.One of those wireless devices is an security camera.Here is my question. I want to view the camera from the internet outside the house. I have followed the instructions given by the manufacture for port forwarding. I have port forwarded the wireless router since the camera is connected to it. Is that wrong since the DSL is coming in one router and then going to another and then to the wireless

setup multiple wireless routers to one Internet connection. We have one cable modem (with built in wireless router) for Internet connection. Over a wide area (500 feet over two floors) I would like to connect to the Internet throughout this area wirelessly. The computers sharing the connection do not need to share with each other and do not need to see each other. Security is not a major factor. The building material is cinder brick walls (which weakens the wireless signal quickly).I have several older (2008 or 2009) wireless routers. I was thinking of putting these routers at various locations in the building with a wired connection back to the WAN modem. Each wireless router could the service a smaller area in the building.My plan is to turn off the DHCP on each wireless router. Do I need to run a wired cable (lan port to Lan port) back to the cable modem or can I use the wireless routers to connect to the wireless cable modem?

I've recently bought another PC, but set it up in a different area than my existing computers. It's down in my basement, along with my PS3, Xbox 360, and Wii. Now the problem is connecting all of these "toys" to the internet. I only have one in-wall ethernet port, which my PC is currently plugged into. Leaving my PS3, Xbox, and Wii, only with an extremely weak wireless connection. Now, my original thought was just to buy a network "switch," BUT then I remembered I have an old D-Link router. So, logically I should be able to plug an ethernet into the wall, then into the WAD port on my router, then plug my Xbox, PS3, Wii, and PC into the 4 remaining LAN ports on my router. I want another WiFi access point using the same network, and a wired connection for all of my gadgets.

There are a few discussions on this topic but nothing I can find indicated definativley shows that this can be done with this model.I have an ADSL service that came with 1 IP address and then we later purchased an additional 4 IPs (2 usable) for the same service.On our network we have SBS2011 and also a dedicated web server. What I would like to do is forward HTTPS to the web server on our inital IP and then forward https for OWA to one of the IPs on the additional set.Our initial IP is xxx.yyy.104.112 which I would like to forward port 443 to 192.168.0.12 - web server
The additional IPs are :
aaa.bbb.30.24 (Gateway Address)
aaa.bbb.30.25
aaa.bbb.30.26 - I would like to forward this to 192.168.0.2 - SBS box
aaa.bbb.30.27
I have tried as suggested in other thread setting up a software DMZ that sends public IP aaa.bbb.30.26 to 192.168.0.12. The xxx.yyy.104.112 to 192.168.0.12 works with a port 443 forward fine.
When I do this I cant connect from outside. If I change the port forward on 443 to go to 192.168.0.2 I can get to the SBS box from outside using the aaa.bbb.30.26 address .I have also tried creating a subinterface for the aaa.bbb.30.24 addresses and this also doesnot seem to work. Just I am basically asking for confirmation that this can be done with this model, I have put in the latest firmware.

At my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address 24.244.208.101 would be assigned to LAN port 1, 24.244.208.102 would be assigned to LAN port 2, and 24.244.208.103 would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?

I manage the I.T. department for an ambulance service. We have 12 ambulances all equipped with Verizon 4G LTE Samsung hotspot cards. [code] There are laptops in each of the ambulances that connect to the wireless cards in the ambulance via DHCP. I get frequent problems when the vehicle get close to each other of them jumping from one card to another... which is not a huge problem, except when it happens the computer will have a "limited connectivity" to the internet. This sometimes will resolve after 3-5 minutes on its own, or if i disconnect from the wireless card and reconnect it will resolve, or sometimes by rebooting the wireless card it will resolve.We also need the ability to move the laptops from one ambulance to another as well so we need to have this flexibility.would I be better off establishing the same IP address to each of the wireless cards, still keeping different SSID's and different channel #'s and then hard code the IP address into the laptop instead of using DHCP to connect? My goal is to eliminate the limited connectivity issue.

I have an unusual deployment scenario which may require the use of a SRP-521W, the scenario is as follows:Temporary Setup:Cisco 857 As the ADSL router until Ethernet Hand-off is installedMultiple IP addresses delivered on the ADSL WAN serviceCisco 857 put into Bridge Mode and connected to SRP-521W WAN portCisco 521W handles the Authentication and RoutingCheck Point Firewall System connected to SRP-521W LAN-1Check Point Firewall has WAN IP 203.XXX.XXX.XXXCisco UC-540W Connected to SRP-521W LAN-2Cisco UC-540W has WAN IP 203.XX.XX.XX If you understand the above scenario, I am curious if this can be done and if so how? I need to keep the networks totaly separate and the only thing they would have in common is the Cisco SRP-521W.It should also be noted that the SRP-521W Is being used because the ADSL service is only temporary whilst the Fibre Build is completed and the carrier provides an Ethernet Hand-Off, then the Internet service will change to this type of presentation and the ADSL router will be relegated to the dark world of loneliness.I have gone through the router and have been playing around with the settings, the issue Is I have nothing in the LAB work up that can allow me to replicate this environment and test it before deployment... So, how to reduce the amount of trail and error I have to encounter to get it to work.
