IP Address Conflict

I haven't had problems connecting to my network until a few weeks ago. I get a message in my toolbar saying "There is an IP address conflict with another computer on the network. Click on this window to resolve the problem". If I click on the window it goes away only to come back a few minutes later. However, if I am not there, after the message comes up several times it boots me off and will not let me reconnect to the network. Does anyone know how I can repair this?

    I have a wireless network covering a campus area. i run the network on DHCP until i started noticing ip conflict on the network. I felt someone was trying to play games so i stopped dhcp and went static. that gave peace for a while and then the ip conflict is back again. i can't place exactly where the conflict is coming from now as all the users have static ip address and windows xp does not identify the person conflicting. what can i do?

I get the error message (Basic) Onhook IP Conflict on my Altigen IP705

IP address conflict occurs when two or more computers on the same LAN network end up with the same IP address. When this occurs, both computers end up not being able to connect to network.There are a few ways in which this problem can be fixed.If it is Static IP request your ISP for a change of IP.If it is a Dynamic IP you can try resetting your modem by switching ON and OFF the modem or open the command prompt and type "ipconfig /release," which dumps the automatic address it had, and then "ipconfig /renew," which gets a new address.To check for the change in IP you can visit which gives your public IP when you visit the site.

IP Conflicts in a work place

An IP address conflict occurs when two computers on a LAN or the Internet have been assigned the same IP. IP conflicts between two computers normally render either one or both of them unusable for network operations.

How IP Address Conflicts Happen

Two computers can acquire conflicting IP addresses in any of several ways:

· A system administrator assigns two computers on the LAN the same Static IP Address.

· A system administrator assigns a computer a static IP address within the local network's DHCP range (dynamic IP range), and the same address is automatically assigned by the LAN DHCP server.

· A malfunction in the network's DHCP server allows the same dynamic address to automatically be assigned to multiple computers.

· An ISP accidentally assigns two customers the same IP address (either statically or dynamically).

· A mobile computer is put into standby / hibernate mode and then awakened later.

Note that other forms of IP conflicts can also occur on a network. For example, one computer may experience an IP address conflict with itself if that computer is configured with multiple Network Adapters. System administrators may also create IP conflicts by accidentally connecting two ports of a network switch or router to each other.

Recognizing IP Address Conflicts

On most Microsoft Windows computers, if you attempt to set a fixed (static) IP address that is already active on the local network, you will receive the following pop-up error message:

The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.

On newer Microsoft Windows computers having dynamic IP conflicts, you should receive a balloon error message in the Taskbar as soon as the operating system detects the issue:

There is an IP address conflict with another system on the network.

Sometimes, especially on older Windows computers, a message similar to the following may instead appear in a pop-up window:

The system has detected a conflict for IP address...

On Mac or Linux computers, a similar message will normally appear on screen.

Resolving IP Address Conflicts

Try the following remedies for IP conflicts:

1. For networks where IP addresses are fixed (statically assigned), ensure each local host is configured with a unique IP address.

2. If your computer has a dynamically assigned address, releasing and renewing its IP address can workaround IP address conflicts.
3. If your home router is believed to have a faulty DHCP server causing IP conflicts on the home network, upgrading the router firmware may resolve this problem.

Identify the peripheral conflicting with the router and change the network address on one of the two. Their setup programs should give you the possibility to do so. The address should look like: 192.168.2.x
x ranging from 0 to 9

Im try to set up an wireless connection but it always seams to have a problem, one of them is that the sistem says that i have an ip comflict! what can i do?

If your getting that message on your computer that means the IP address that your computer acquied from your serverrouter has a duplicate in the network. The very first thing that you need to check is whethere your computer has a an IP address that is manually assigned to it, to check this just go to Network Connections under Control Panel(assuming your computer runs on Windows XP). Right click on the Wireless Connection icon and go to properties, under Local Area Network Properties you will find several check marks under This device uses the following; Client for Microsoft, File and Printer Sharing, QoS Packet Scheduler etc... Look for and highlight Internet Protocol(TCP/IP) and click Properties, under the TCP/IP Properties you have 2 option for both IP and DNS server. Make sure both is set to obtain. If your still getting the same message Right click on Wireless Connection and choose repair so tha your router/server will provide a new unique IP address, wel that will usually resolve the IP address conflict on your computer.

Loosing connection frequently

Your computer has an IP addy and your router has its own IP addy. Try uninstalling the router and its software, reboot, and reinstall everything, this may clear up the conflict. If not you will have to go into the router(via the internet) and reconfigure the router.
