Warning that another computer is using my ip address

What do I do if I receive a warning that another device is using my ip address on the macbook air?

     Simple solution would be to renew your IP address and you might get issued a new (different) one.
     However, in some scenarios this will not work as the conflicting machine could have that address statically assigned and the dhcp server could have no idea of this.
     Does this happen at your home? school? work? If its at home, check all the other devices on your network and check to see if any of them have a static. If at school or work contact the network admin and let them know - personally I'd be a little upset if someone was using an unauthorized static on a network I was responsible for.

  • I got a notice saying that another computer is using my ip address

    I'm not sure what this means, or what consequences it could have.  Also recently our internet usage also spiked- and we've not changed our internet habits, could this have something to do with it? I have no idea about any of this kind of thing, should I be worried?

    Where did this notice come from? 

  • HT2433 what does the error message that says " You are logged out because another computer is using this IP address." mean?

    what does the error message that says " You are logged out because another computer is using this IP address." mean?

    Some other piece of network ghardware on your home LAN (Local Area Network) is using the IP address your Mac is trying to use.
    Reboot both your modem and router, or the Modem/Router combo box you have, and all pieces of networking equipment, computers and printers, you have connected to your LAN.
    If you continue to get that error then it is a bug in OS X or you have your Mac set to a Static IP address that is being handed out by the routers DHCP server to some other device.

  • My new laptop says another computer is using my ip address. How do I stop this?  I was trying to get all of my stuff off my parents desktop IMAC and think I screwed something up with the wifi because now my laptop won't connect to wifi

    I bought my own laptop (Macbook Pro) and set it up and am using wifi that my parents use on their computer.  Everything was working great until I wanted to put my itunes from the desktop to my laptop.  I used my Mom's sign on of her apple id and since then when I log on to my laptop it says another computer is using my ip address...what do I do?  Thanks!

    Hey there Toni D.,
    I suggest the troubleshooting outlined in this article here:
    Wi-Fi: How to troubleshoot Wi-Fi connectivity
    http://support.apple.com/kb/HT4628?viewlocale=en_US
    Does the symptom occur with more than one Wi-Fi device?
    Wi-Fi issues may be related to the network in question or they may be related to the Wi-Fi computer joining that network. Usually, if other computers or devices (such as the Apple TV or iPhone) are able to get on the Internet without issues, then your Wi-Fi router is probably fine.
    If you only have one Wi-Fi device, proceed with this article.
    Make sure your software is up-to-date.
    Install all software updates available for your Mac.
    If you use a third-party Wi-Fi router, check with the manufacturer to confirm that it has the latest firmware installed. If an update is available, follow the manufacturer's instructions for updating the firmware.
    To determine if your Apple Wi-Fi base station firmware is up-to-date, see Updating your software.
    Check your connections.
    Some networking issues may be caused by loose or disconnected cables. Verify that all Ethernet and power cables connected between your modem and your Wi-Fi router are correct. Checking that devices such as your router and modem are on, disconnecting and carefully reconnecting Ethernet cables, and/or replacing damaged Ethernet cables may resolve the issue without any further troubleshooting.
    Verify that you are using the recommended settings for your device.See Recommended settings for Wi-Fi routers and access points.
    Restart your network devices.Powering your modem or router off for a few seconds and then on again may resolve network issues without any additional troubleshooting. If you have phone service through your ISP, power cycling your modem may interrupt that service. You may need to contact your ISP in order to restore your phone service if your modem is reset or powered off. Ensure that you have alternative means to contact your ISP (such as a cell phone) to avoid unnecessary delays in restoring your Internet or phone service
    And if this does not get the network connection going again I would use the troubleshooting from down the bottom in the section labeled Symptom: My Mac does not connect to the Internet.
    Take care,
    Sterling

  • Airport Extreme message states I don't have an IP address and also states that another device is using my IP address.  At

    I am getting two error messages as I attempt to login on my iMac.  One says I don't have an IP address and another says that another device is using my IP address and won't allow me to login.  Any advice?

    Is your AirPort Extreme Base Station (AEBS) the only router in your network configuration? That is, is it connected directly (by Ethernet) to an Internet Broadband modem OR to another router upstream of it? Regardless, what it the make & model of the device that it is connected to in order for it to gain Internet access?

  • When setting up my Time Capsule I get an error message that another device is using my computer's IP address.  What can I do about this?

    When I am setting up my new Time Capsule I get a pop up window that says another device is using my IP address and I have to change it.  My time capsule will not work or connect to the Internet.  I assume that is why.  Everything is plugged in as should be.  I also have a wireless DVD player and my DISH network plugged in to the Ethernet of the Time Capsule.

    You need to do the setup of the TC before you plug it into the network.. you obviously already have a router, so set the TC up as bridge device.. in airport utility/internet tab/connection sharing.. off bridge mode.. then you can plug it into the network and whatever is main router will do its job properly.
    If this is not the case, then you have a static IP setup somewhere.. or another dhcp server.. track down and remove it.

  • I just bought mine last night and when i turned it on today it said another device was using my ip address.  I have an iPhone is that what it meant?

    I just bought my MacPro laptop last night and when I started it up this morning it said another device was using my ip address?  I have an iphone is that what it meant

    It probably means you've manually set an ip address of another device on your network to the ip address that your dhcp server wants to assign to your computer. Or, it means that a neighbor has connected to your network with a fixed ip address that your dhcp server wants to assign to your computer. Or, it means that you are really connecting to a neighbor's network and you've set your computer's ip address manually to an address your neighbor is already using for one of his devices.
    Make sure that all your network devices are set to receive their ip Address automatically (dhcp). Restart your router and all connected devices to see if that clears up the problem.

  • My email address has changed and when I try to play purchased songs it asks me to authorize another computer under the old email address.  How do I play the music that I have purchased?  My account is current with the new email address.

    My email address has changed and when I try to play purchased songs it asks me to authorize another computer under the old email address.  How do I play the music that I have purchased?  My account is current with the new email address.

    You may have already done this, but try de-authorizing your computer (through the iTunes:Store menu) and then re-authorizing it.

  • Deauthorizing iTunes on a computer?  My laptop won't let me connect my iPhone because it says I'm authorized on too many computers, but when I try to de-authorize another computer I use it won't let me.  What's up?

    Deauthorizing iTunes on a computer?  My laptop won't let me connect my iPhone because it says I'm authorized on too many computers, but when I try to de-authorize another computer I use it won't let me.  What's up?

    What do you mean it won't let you?  What exactly does it say? (Sorry to sound so exasperated but this is like the 6th post in a row where people have made vague statements which do little to help us find solutions without a game of 20 questions.)  I'm going to guess and say you can only deauthorize a computer to which you have physical access or VPN login.  The alternative is to deauthorize all which you can only do once a year.

  • Can't connect to my itunes because the message states that another user is using my itunes when thi is not true.

    I can not connect to my itunes account because the message states that another user in using the account and this is not true.

    After a visit to the apple store, they were able to get through my pass code but unfortunately I found out that is was a problem with the logic board. Since Apple only wants to sell and not fix, I was able to locate an iphone repair near me that deals with logic boards and they are currently working on it right now. i should be getting it back soon. Im not sure if the problem you are experiencing is the same as i went through but it does sound like it may be also a hardware issue and would suggest searching online for an iphone repair place that can diagnose what exactly is wrong. Hope this helps.

  • Another device is using my IP address?

    This morning I started my computer up and a notice popped up on my screen. It said another device was using my IP address and to try again later. I'm not sure what I was supposed to try again later and does this mean my computer has been hacked or is being remotely accessed somewhere? Thanks for any help.

    If they are sharing a router, then they are on the same network. Next time you see that error, write down the IP that's conflicted. Then check your computers' and router's IP addresses. If one device say, your router, has that IP address, and one notebook is trying to acquire the same IP, then you've pinpointed your conflict.

  • Another device is using my IP address.  Should I be concerned?

    I received a message on my computer.  Another device is using my IP address.  Should I be concerned?  What should I do to prevent this?

    The error message reads:  "Another device on the network is using your computer's IP address.  Try connecting again later.  If you continue to have problems, change the IP address of this computer or the IP address of the other device.  Contact the network administrator if you need more information".
    I do not have an iPad and my iPod is turned off.  I DO have an Apple TV device.  Could that be it?
