OS X Mavericks :: Another Device On Network Is Using IP Address
Sep 8, 2014
a macbook air and an iMac have both give the error "Another device on the network is using your IP address". They are both using the latest OSX and are both set to use DHCP assigned by my Virgin cable router.the address reported in the popup window is NOT the address that either computer was assigned at the time (the first time, I thought it was odd, and I had an iPad handy and used fing to search my network to see what device had just used that address and I didn't see anything). This time - I was on my iMac and happen to have a terminal open, so I did a quick if config - and my ip address was not the one indicated in the message (it was saying 192.168.0.8) and my address was 192.168.0.12. In fact I think that the other day it was complaining about the same .0.8 address.
I do have 2 devices that have a hard coded ip-address (but they are right at the beginning of the range, and in fact I have instructed the router to skip those addresses and just dish out ip's from .0.3 onwards). All other devices use DHCP.Â
I just secured the wireless router and network for my roommate the other day. When I got back in town today and tried connecting to the internet, it told me that another device on the network is using your computer's IP address. I have no idea what this means and what I have to do to fix it... any thoughts?
Every couple of days my computer (13 inch macbook pro) will disconnect from the Internet giving me a pop up saying 'another device on the network is using your computers IP address' it later says to change my IP address but I don't have one because I have an airport express router. What can I do about this?
Two days ago, I installed AppleTV at my house. Not sure if this is the culprit, but my issues started after it was installed. My MBP will works fine on my home network, then randomly loses the Internet connection. Today, I was able to catch an error message that stated another device was using my computers IP address. So, I checked the ATV, and it was not. Then, I checked my iPhone...and it was! I reset my modem, reconnected my MBP...everything was fine. I then turned on the screen to my iPhone. It happened again. I noticed the iPhone was using the same IP address as my MBP. This time, I reset the modem, and made sure my iPhone was using WiFi when I did this. Now I'm up and running. All devices are set using DHCP. Would it be better to assign Static IP addresses? I've never done this, and don't want to screw anything up.
At my house, I have a lot of wireless devices: 3 laptops 3 iPhones 1 AppleTV 1 iTouch 4G Plugged into the modem is my desktop computer and an AT&T Microcell. Would the addition of 1 more device (AppleTV) to my network start causing these problems?
I had my two macs turned on and using the internet on both but for some reason a got a message saying that both computers were using the same IP address. I didn't loose connection on either one, everything was working normal. The same IP address of your computer is used by some other device in the network...
I keep getting a pop up saying, anotherdevice or network is using my ip adress, so im unable to get to the web. I have reset my router and airport extreme but it still keeps giving me that pop up. Do I change my IP adress and how.
I've got a rather strange thing happening...Disable ALL network interfaces, including Bluetooth, have only my Ethernet enabled, going directly to DSL modem (not router).Yet, I am picking up a computer in my network browser. I can browse this computer's shared docs just fine, and in fact, he is not setup very securely so I could easily delete his entire music and photo library or send malicious files to him (or her).
But, I am wondering how I am even seeing this device. From what I know, on a DSL connection, you should never see any other computers on that ISP. I know sometimes this will happen with Cable, but I've never seen it on DSL.How do I find the IP or MAC address of this computer? I actually work at my internet provider, and I'd like to see if I can find which customer it is and why I am picking them up on my network browser, and hopefully alleviate the problem.
I'm new to mac and don't have any idea on how I got this one. I already tried to restart my machine but the "ibmt61l3cv479" keeps on displaying on the Shared list. I didn't connect to any PC Servers and afraid that someone is accessing my mac.
I have a credit card terminal I want to use at a farmers market and it has a phone jack and an ethernet jack. If I have my laptop connected to my iphone via the hotspot (wifi), how can I get the terminal to see the laptop as a network? I assume if I just plug it into the the lapto via ethernet cabel, it will not see any connection for use, though I have not tried this yet. Is there some sort of interface or connecter that goes between the two so I can share my connection with another piece of hardware?
How to automatically mount other Macs on the network, or if not, then post an explanation here on how to accomplish that objective?Â
For example, my Mac Pro tower has 4 disks and when I boot up all 4 disks are mounted. Then, when I turn on my Macbook Air and turn on my MacBook Pro, those laptops show up in Finder as shared. The Macbook Pro is partitioned, so it would be nice if I could specify which disk to mount in Finder.
I'm having some trouble adding network printers in Tiger. If I open the print&fax window and then click on the "+" sign to add printers, nothing comes up. I thought a new screen was supposed to pop up, but nothing happens. If I try to print something from Word or Excel and select "add printer" in the print menu, also nothing happens. I do find a list of "bonjour printers", but I'm not sure how this can help me. So in the end it seems I can't add any printers at all, and thus not print.
my daughters SLEEPING MBP has appeared on my MBP as a shared device. How is this possible if it's sleeping? Perhaps there's a good explanation for this, but I'm concerned about it. She connects via wireless to our home D-link wireless router. Wasn't sure where to ask question on boards..
Info: Macbook Pro 2.53 Intel i5, Mac OS X (10.6.7)
I currently have 1 PC (Windows7) and 1 MBP (Snow Leopard) in the house, the PC has 2 additional HDDs attached with movies and music on them and they are in NTFS format. I can view the contents on my PC via my wireless G network on my Macbook through sharing etc. Now my problem is that I'm getting rid of the PC (hopefully for an iMac in the future) but right now what sort of device would I need to build/buy to attach the 2 NTFS HDDs to the network so my MBP can still access the media on them?
I recently bought a Hp OfficeJet pro 8600 plus printer and have set it up fine on my desktop pc. When I went to install it on my MacBook it wont let me set it wirelessly because it states that The wireless network settings were successfully downloaded to your device. However, your Mac was unable to locate the device on the network.
Please make sure that: - Your Mac is connected to a wired or wireless network that has access to your device. - Your device is connected to the wireless network "home".
Click "Retry" to attempt to connect again using the current settings. Click "Go Back" to enter different settings. The weird part is that everything is set up fine as far as the printer it seems that the mac doesn't want to cooperate. I am running OS X Lion with the newest downloads and updated.
Info: MacBook Pro (17-inch Mid 2010), Mac OS X (10.7.4)
how created an unused network that is showing up on the list of networks in the building.  i need to delete it. I went to System Preferences, then Network, then Advanced but the next screen befuddled me as there was no "Wi-Fi".Â
I am trying to share a DVD drive over my LAN. We have three computers.Â
I have an iMac, with DVD drive sharing enabled, without the requirement of asking me for permission.Â
I also have a MBP, with the same DVD sharing enabled, and a Mac Pro, again with the same settings (it has no DVD drive).Â
The iMac can see a disk in the MBP's drive and the drive is listed in devices.Â
But the MBP cannot see the disk in the iMac's drive, and nothing is listed in devices. Nor can the MP see the iMacs DVD device, and it can't see a disk in the MBP's drive.Â
So out of three, only the iMac can see DVD drives as devices.Â
Note that if on the MBP I mount a disk, and then access the MBP computer I can mount that volume. But it still doesn't show as a device, which is how it should work.Â
I have done all the usual stuff. All other network access is fine. No firewall issues. All on the same LAN, working over ethernet.Â
I can not seem to sync my mac or enable "back to my mac" because I am being told that "I may have more than one device on my network providing Network Address Translation. Well, this is news to me. I have a Time capsule running my network and an Airport Express with Airtunes dvice and they have been hooked up for more than two years. I have been abloe to sync my network up until recently and I do not recall making any changes to any network configurations so I am clueless as to why things suddenly stopped working in this regard.
THe error message tells me to disable Network Address Translation on one of the devices but does not tell me how to do that. Nor can I find any information related to Network Address Translation on the help database.
When I try to connect to a wireless network. It says there is no IP address? I know nothing about computers. The mac shoppe told me I needed to erase everything and re-install my software. I did this, and it still doesn't work. I'm very frustrated because I lost everything when I did this! When I connect directly to the modem, it works fine.
I have two laptops on the same network. When one of them is on, the other cannot get on because of this IP conflict, and vice versa. How do I change one of the IP addresses so I can get both laptops on the network at the same time? I'm looking to transfer music between two laptops and because they both can't connect to the network at the same time (Mac and PC), I can't transfer the files.
I used to know a command that would show all of the ip address and the name of the devices on your network. I have not use the command in a while and I forgot it.
After initially installing win 7, and taking a few stabs at the correct driver for the wireless card in my mac pro (apple installed), i got wifi working with a public network.
HOWEVER, i installed windows updates, restarted, and now it's just not working again!
it says that there is not a valid ip address... my macs get on fine...
how to diagnose and fix? the win 7 dianostics do nothing.
I'm running snow leopard on Macbook Pro. My college has free internet access and every hostel has different IP addresses assigned. My hostel has this IP address 10.165.x.x. The students keep changing their IP address and somehow my macbook pro disables me from accessing the internet when a windows OS user in the network uses the same as mine. Somehow windows OS doesn't allow the second user to use if its already taken but my poor mac OS allows it even while m using and I'll be thrown out. I'll have to look out for a new ip address which is not taken already. How I can protect my own IP address?
I have a mac mini. I used boot camp Assistant to install windows 7, and to make the partition screen stayed black and I get the following poster:Â "no bootable device- insert boot disk and press any key".
Can any one tell me how to determine the IP address of a network printer. I have an OKIpage 12i which suddenly can't be seen via Appletalk, so I was going to try to connect to it using IP (which is how I connect to the Xerox Phaser we also have)
Where I work there is a "free, pubic" wireless network. I can access it with my PB G4, and it will show two or three bars of connection. But, I'm informed that my computer is not connected to the internet and when I check the Network control panel I'm it shows that my PB has a self assigned IP address. Meanwhile, someone with a Windows laptop sitting right next to me can connect without issue.
Network Section in Finder shows "nstest.tzo.com". I've never used any service at this address or installed any questionable programs. Has anyone ever seen this sort of thing appear in their networks or know could I get rid of it? Spotlight search shows nothing except the google searches I did once I saw the entry.
