"another device is using your IP address"

Occasionally, I get a prompt from the notebook telling me, "another device is using your IP address".  What does this mean?

Sometimes this message means that you have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
Sometimes it happens because a device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
A third-party wireless router that has incompatible settings or firmware may be the cause. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

  • New iPhone 5, getting the "Another device is using your IP address" message

    just got the iPhone on Sunday and turned on the WiFi. Everything was ok until today. Now when I walk into the door and wake up my Mac Mini (OS10.7.5), I get: Another Device on the network is using your computers IP address.
    I then have to reboot the AIrport and turn off WiFi on the iPhone. Things were better.
    According to this article:

    there's a chance my iPhone is commanding the space. I suspected as much because this has  happened before with other Apple products here. Any thoughts on this?

    Reset your router. Two devices are attempting to use the same IP address.

  • 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.

  • 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.

  • 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?

  • HT4199 how do I fix it when "another device is using computer IP address" and I can't get wireless to work anymore? It used to work fine.

    How do I fix it when "another device is using computer IP address"? Airport used to work fine. I've already tried turning everything on and off several times.

    I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
    Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
    Power-up your computer(s).
    If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
    Disconnect the AirPort base station from the Internet broadband modem.
    While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    After the base station resets, go ahead and power it back down.
    Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
    Continue with step 2 in the first set of steps.
    In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

  • 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?

  • We have a router at home supposed to support 10 devices but when i try to connect my mac book pro it says another device is using your computer's ip address

    we have a router at home that is supposed to support 10 devices but when i try to connect my mac book pro it says another device is using my computer's ip address

    Are the IP addresses statically assigned (wrong ), or does the router give them out using DHCP (right )?

  • Get the message - another device is using the same address

    I keep getting the message that another device is using the same ip address. I have to turn off my MacBook Pro from wifi and then back on again. Sometimes the wifi doesn't come back on for my MacBook Pro.
    Running Mountain Lion. Thought all this hassle would be solved.

    To follow up on what Thomas has said.
    You have a device on your network that is using a fixed IP address in the range of addresses that your router assigns addresses from. You'll need to figure out what device that is and change its settings so that it gets a dynamic IP address assigned by the wireless router.
    Or your MBP has a Fixed IP.
    Or if you need certain devices to have Fixed IPs, like a printers which should always be assigned a fixed IP, then you need to assign those IPs out side the DHCP Pool range the router uses to hand out Dynamic IP but yet still in the total range of the routers IP address.

  • Notification that stated another device was using my IP address

    Opened my MBP and a notification appeared that another device on the network was using my laptop's IP address. My iPhone was also turned on. What does this notification mean? Could it have been my iPhone? HELP!

    It means that you have a router that issues IP address in sequence rather than basing the IP address on a hash of the requesters MAC address.
    You turned on your computer and it got the first IP address.
    You turned off your computer and waited until the lease for that IP address expired.
    You enabled WiFi on your phone and it was issued the first IP address.
    You turned on the computer and it requested the last IP address that it had.
    Since that IP address is in use by the phone the requested IP address was rejected with the error message.
    The router should have then issued the next IP address in the sequence to the computer.
    The way around this problem is to configure the router with DHCP reservations or Static reservations so each device always gets the same IP address.

  • Another device is using my IP address...I don't have another mac?

    I am getting this message:
    Another device on the network is using your computer’s IP address (IP Address).er’s IP address (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.
    Is this bad?  Is this a security issue?

    Out of the blue today, I started having this problem.  All devices on my home network have assigned IPs.  First my wife's Mac said there was an IP conflict.  I was able to ping it when it was on, but when it was shut down, I was not able to ping that IP.  Now my desktop and my laptop are doing the same thing.  Cold reboots do not help.  The router assignes IPs between 200 and 225 whereas my assigned IPs are below 125..  So even when I switch my laptop to DHCP, and get an assigned IP, I get the message that there is an IP conflict.  Have rebooded the airport base that is the router and assigns IPs.  In th emorning, I will turn everything off and restart one machine at a time to see if I can find a cupprit.  Very odd.no network configurations were changed.

  • HT5293 what does it mean if this pops up when getting on a network. it read, unable to join due to another device is using this ip address.

    what does it mean when the message , "can not join network due to another device using this ip address?"

    Most likely, you're getting a network address from your router. The address assignment ("lease") expires, and has to be renewed, after a certain amount of time, which might be one hour or one day. The lease expired without being renewed because the device was offline at the time. Meanwhile, the address was leased to another device on the network. When the first device comes back online, it still has the address that's now also leased to the second device. Depending on what kind of router you have, the conflict may resolve itself automatically. If not, then from the menu bar, select
     ▹ System Preferences ▹ Network
    If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the TCP/IP tab. Now look at the menu labeled Configure IPv4. If the selection in that menu is Using DHCP, click the button labeled Renew DHCP Lease. Test.
    Less likely, you have a network address that you assigned yourself, and another device is assigning itself the same address. In that case, the selection in the Configure IPv4 menu will be either Manually or Using DHCP with manual address. This kind of conflict won't be resolved automatically. You have the following options to resolve it:
    Change the menu selection to Using DHCP.
    Change the manually-assigned address to one that isn't being used by another device.
    Change the address of the other device.  
    Which of these options you should choose depends on the details of why you're using a static IP address. Any change you make to the network settings must be applied before it takes effect. To do that, click OK and then Apply.

  • Another device is using your computer's IP address

    I recently started using TimeCapsule as a backup and as a router. Could there be a connection between this error message and TimeCapsule. Other computers and devices in the household are not having problems connecting to the Internet. Solutions?

    By any chance have you recently had to reboot your airport/time capsule affair.  Similar thing happened to me, had to reboot the AEBS and my wife's computer was in sleep mode at the time.  When I fired up my iMac it gave me a new IP address and all was well until she brought her computer out of sleep.  Turns out the IP address I had been assigned was her old one.  A reboot of her computer gave her a new IP address. 

  • Another device is using this IP address?

    My time capsule keeps flashing an amber light and I get this message. My wi-fi won't work at all either since its used through the time capsule.  I recently bought a new iphone if that may be The problem but I'm not sure what this means, and is there anyway to fix this?

    What you want to do is power cycle the Time Capsule. This will reset the DHCP leases and should fix the problem.
