IP address conflict - pls help...

Hi
I get on my iMac (and also on the MacBook) sometimes the message: *Another device on the network is using your computer's IP address (10.0.0.8).* After a view seconds (and evidently a change of the IP address) Ethernet connectivity works again. When does this happen: e.g. after waking up the Laptop from sleep modus.
Here is my setup:
. ADSL router with 10.0.0.138 GW address
. all devices directly connected via a Gigabit switch
. most devices are set to DHCP except one
. one device needs to have a manual set IP address (set now to 10.0.0.180), because it does not support DHCP (is a special HW for the solar system)
. devices connected via Ethernet cable include:
          - iMac DHCP
          - Windows PC DHCP
          - Apple Time Capsule DHCP
          - PS3 DHCP
          - TV Samsung LED DHCP
          - SAT Receiver Sky+ DHCP
          - NAS DHCP
           - Fronius Data Logger static IP 10.0.0.180
. devices connected via WLAN (to Apple Time Capsule) all using DHCP
          - Apple TV
          - Wii
          - iPhone 4
          - 2 iPads
          - Samsung mobile phone
          - MacBook
All have DCHP activated.
I dont understand how a device can get the same IP address from the DHCP and so causing an IP address conflict. Unless, there are 2 active, which I did not yet figure out...
What did I change lately (before this change, I did not have this problem)?
. I had another router behind the ADSL router, set to 192.168.0.x internal address range for the home network. It got broke so I took it out of the setup as the new ADSL router anyway has a firewall. Since then I have these issues.
What does "got broke" mean - as I am not sure whether this helps in finding the root cause: what happened is that after our vacation when I switched on all clients again I could surf the Internet lets say for 1hour or so and then suddenly all clients lost connection and had an 169.254.0.x IP address. And this although DCHP IP address lifetime of the router was set to 24h and the actual lifetime of the clients IP addresses where in that range (as I reseted the router). Before our vacation all was fine. BTW, the ADSL router works fine (I use also IPTV service over it and it works perfectly all the time).
So before that change, I had a private network segment with 192.168.0.x extending from the router to all wireline devices. I am not sure, but it can be that the Time Capsule, i.e. the wireless network, was on 10.0.0.x (I dont know). Then things would be clear to me, as then evidently the Time Capsule runs a separte DHCP from which the wireless devices fetch their IP address and if they are now all in the same network segment (both wireless and wireline)...then "Houston we have a problem":)
So my questions are:
. is the Airport setting of the Time Capsule wrong? I used "create a wireless network". Is it now just extending the 10.0.0.x network to the wireless domain? Hence do the wireless clients fetch their IP addresses from the ADSL router or the Time Capsule?
. Is the wireless and wireline network fully transparent, can wireless devices connect without problems to a wireline device (e.g. the MacBook to the NAS)?
. Is there an app that helps to identify the clients? I can get from my router a list of IP addresses used by clients, but I cannot link them to the devices.

I am having a similar issue as described in another post. search "Time Capsule IP address Conflict".   This is a relatively large home network with a number of media devices, PCs and Macs on a network behind and ATT uverse 2wir router.
Everything worked fine until I added the Time Capsule to the network. Initially the TC got an IP address frou the 2wire router and all was fine.   But the next day I recieved and IP addres conflict from a Mac Book.
TC is Bridge mode - Wireless turned off - attached diretly to a lan port on the 2wire router.
It looked like the TC recieved an IP address from the 2wire router but the 2wire indicated that it was a static IP, rather than one being issued by DHCP. The 2wire handed out the same address to the Mac Book.
I shut down the TC and the Mac Book, rebooted the TC and Mac Book. Everything seemd to be fine. This time the TC got an address from the 2wire DHCP pool 192.168.1.113.   This gave me the opportunity to reserve the address hoping that the TC would get this address every time, and keep it from being handed out to another device.
Everything seemed fine for a day.
Next day we get another address conflict.
The airport utility on an Imac still says that the TC is 192.168.1.113 but the 2wire router does not show the .113 address. Instead it says that the TC has a static IP of .117 .
The Mac Book shows an address of .117.
Shut down the TC
Shut Down the Mac Book
Reboot the Mac Book and Manually assign .120
Change the Macbook to get DHCP address.   It now Gets .120    I reserve .120 for the mac Book
Reboot the TC
It gets .113 and shows up on the 2wire router as .113 issued from DHCP.
Reserver .113 for the TC again.
Waiting to see what happens.
Does the TC go to sleep?
If so does it lose its IP assignment and get a new one when it wakes up?
While it's asleep does DHCP try to give its address to another device?
I would be tempted to blame the DHCP service in the 2wire router accept everything works fine when the TC is not on the network.

IP Address Conflict error - help please

Hello. I have read many related threads but to no avail for fixing my problem.
I have a home wireless network. It worked flawlessly until a few days ago, and now I'm having problems. When I noticed I was having problems, I opened airport utility, and it prompted me to upgrade my routers to 7.6.1, which I did, but the problems still exist (and I believe they did before the upgrade).
I'm having two problems, maybe related or not
* my wife's iPhone cannot connect to the network anymore
* my MacBook Air cannot connect anymore, and occasional shows an error: "another device on the network is using your computer's IP address".
Other computers -- my iMac, my iPhone, my iPad -- seem to still connect with no issues
Steps I have taken:
* reboot router
* reboot iPhone
* reboot MacBookAir
* Per community issues with 7.6.1, I did a hard factory reset on the airport extreme, then downloaded Airport Utility 5.6 and used it to roll back the firmware to 7.5.2
* Tried opening network prefs on the MBA, and renewing lease. No IP address is displayed before or after, as I think it doesn't have a lease to renew
* Confirmed that Configure IPv4 is set to "Using DHCP"
* Changed the name of the wireless network
* Tried unsecuring the wireless network
* Changed the channel of the wireless network
* Tried specifying a manual IP addrss in the same range for the MBA
None of these things has been effective in getting to the network -- something I had no issues with until a few days ago. Also, with the MBA, I can still connect to other wireless networks per usual.
Any ideas?
Thanks

IP address conflict help and setting up security code for access

Hi folks, I am about as non-technical as one can get. So I apologize in advance and thank you guys for your patience as everything you tell me will have to be spelled out for me.
Ques 1: I have one desk top computer with internet access through my cable TV provider. On it I have the Linksys WRT54G wireless router. We use two laptops.
Lately I've been getting an error message on my desktop saying there is an IP Address that is in conflict. My son often gets booted off line (on laptop) and so I'm guessing maybe it is his laptop that is in conflict. Please help me resolve this issue.
Quest 2: I would like to set up a security code for our wireless access so that other people will not be able to intrude upon our signal. Can someone walk me through this as well?
Thank you so much!

The most common reason to get two identical IP addresses, is if you are using fixed LAN IP addresses incorrectly on your system.
Do you already use any fixed LAN IP addresses? If so, please state what fixed LAN IP addresses you are using, and also state your DHCP server range.
Rules for using fixed LAN IP addresses on Linksys routers:
With Linksys routers, a fixed (static) LAN IP addresses must be assigned in the device that is using the address. So you need to enter the fixed address in the computer or printer, not in the router.
When using a Linksys router, any fixed LAN IP address must be outside the DHCP server range (typically 192.168.1.100 thru 192.168.1.149), and it cannot end in 0, 1, or 255.
Therefore any fixed LAN IP address would normally need to be in the range of
192.168.1.2 thru 192.168.1.99 or
192.168.1.150 thru 192.168.1.254
assuming you are still using the default DHCP server range.
Also, in the computer, when you set up a static LAN IP address, you would need to set the "Subnet mask" to 255.255.255.0 and the "Default Gateway" to 192.168.1.1 and "DNS server" to 192.168.1.1
It is also important that no two devices on your network be set to the same static LAN IP address.
Check all of your static LAN IP addresses. If you have violated any of the above rules for static LAN IP addresses, it could be the cause for your problem, and you should fix it before attempting any other router repairs or changes.
********* Wireless Security **********
Brfore proceeding with wireless security, you must get your IP address conflict problem solved. Please do the above first.
To set up wireless security, you must use a computer that is wired to the router.
Where to find the router settings: The router's login password is usually on one of the "Administration" pages. The other settings are all found in the "Wireless" or the "Security" section of the router's setup pages, located at 192.168.1.1
First, give your router a unique SSID. Don't use "linksys".
Make sure "SSID Broadcast" is set to "enabled".
Next, leave the router at its default wireless settings (except for the unique SSID), and then use your pc to connect wirelessly to the router. Test your wireless Internet connection and make sure it is working correctly. You must have a properly working wireless connection before setting up wireless security.
To implement wireless security, you need to do one step at a time, then verify that you can still connect your wireless computer to the router.
Next, encrypt your wireless system using the highest level of encryption that all of your wireless devices will support. Common encryption methods are:
WEP - poor (see note below)
WPA (sometimes called PSK, or WPA with TKIP) - good
WPA2 (sometimes called PSK2, or WPA with AES) - best
WPA and WPA2 sometimes come in versions of "personal" and "enterprise". Most home users should use "personal". Also, if you have a choice between AES and TKIP, and your wireless equipment is capable of both, choose AES. With any encryption method, you will need to supply a key (sometimes called a "password" ).
The wireless devices (computers, printers, etc.) that you have will need to be set up with the SSID, encryption method, and key that matches what you entered in the router.
Retest your system and verify that your wireless Internet connection is still working correctly.
And don't forget to give your router a new login password.
Picking Passwords (keys): You should never use a dictionary word as a password. If you use a dictionary word as a password, even WPA2 can be cracked in a few minutes. When you pick your login password and encryption key (or password or passphrase) you should use a random combination of capital letters, small letters, and numbers, but no spaces. A login password, should be 12 characters or more. WPA and WPA2 passwords should be at least 24 characters. Note: Your key, password, or passphrase must not have any spaces in it.
Most home users should have their routers set so that "remote management" of the router is disabled. If you must have this option enabled, then your login password must be increased to a minumum of 24 random characters.
One additional issue is that Windows XP requires a patch to run WPA2. The patch is located in SP3, so you will need SP3 to run WPA2 in Win XP. Vista already supports WPA2.
Note:
WEP is no longer recommended. The FBI has demonstrated that WEP can be cracked in just a few minutes using software tools that are readily available over the Internet. Even a long random character password will not protect you with WEP. You should be using WPA or preferably WPA2 encryption.

How can i detect if my PC is not on Network..... Urgent Pls Help Soon !!!!!

Hello Everyone,
We all know whenever we try to connect to a PC which is not on network, we get UnKnownHostException etc..... by which we can detect that the corresponding PC is not an network(intranet/internet)
But when i send a msg from my PC to my PC, it works fine even if the network is down. I hv provided my PC's IP address instead of using localhost or 127.0.0.1 which reduces the possibility that the msg will not be traversed thru the network.
Any IDEA how this works.
Is There any possible way by which i can detect that my PC is not on network or the PC to which i'm trying to connect is not on network .......
Pls help me out, its really urgent as to be implemented in my Project
Thanks In Advance

Hello Surtee
I have developed a Messeging Service for the eCRM Apllication my company is developing and we r in the final stage of debugging.
Now whenever a user sends a msg to a PC which is not on network, the messaging service automatically sends an Offline mssg to that PC. But know i want ot distinguish wheather the PC to which i'm sending the msg is not on network or am I not on network based on this i need to perform diff. actions, hence i wanted to know that how can i detect .......
Pls see if u canhelp me out ......

There is a problem with this windows installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Pls help, need assistance.

I tried uninstalling my itunes thinking it was perhaps a conflict with the previous version, now I don't have itunes on my pc at all!!
Reading a previous post for this problem, I attempted to uninstall the 6 individual programs from within control panel. Everything uninstalled fine except for the Apple Software Updater which failed to uninstall and gave me the same error message.
I only encountered this when trying to update to the current version of itunes64setup. When using itunes ver 9 on Windows 7, everything was still fine.
Pls help, any assistance would be appreciated.

I have also tried extracting the individual components to the temp file and attempting to install them individually despite being unable to remove the previous install of Apple Software Updater. The outcome, both Apple Software Updater and itunes encountered the same error message during the install process.

Windows 8.1 Hyper-V : IP address conflict on Guest OS

Hi ,
I have just installed Windows 8.1 and I want to move away from VMWare Player and use Hyper-V instead.
I have nevertheless issues with it on the networking side.
Before setting up my VM, I have:
- converted my vmdk to a vhd.
- created a virtual switch in Hyper-V Manager.
After that, i created the VM using the vhd and the virtual switch created beforehand.
Once I boot up the guest OS (Windows 7), I have no internet connectivity on the guest OS, and it says : windows has detected an IP address conflict
Also when I run ipconfig in a command prompt on the guest, I can see an ip address which is the same as my host OS (192.168.1.5) but then I guess that my host system takes the IP back as if i run ipconfig again the IP address is gone.
So I guess that my host and guest OS fight for the same IP. Also the message "windows has detected an IP address conflict" appears on the Guest OS.
Also at times, the guest OS receive a strange IP: 169.254.99.175 which I have no clue where it comes from.
Does anyone has an idea on how to solve the issue?
Also here is a screenshot of the configuration of the Virtual Switch :
Thanks for any help,
Francois

Hi Dan,
I guess that you use IP address reservation on your router (configuring your router so that DHCP always gives the same IP address for a particular MAC address).
As both your virtual machines and host machine will appear on the network as having the same MAC address, they will both get assigned the same IP by the router.
The solution is to turn off IP Address reservation. Another option is to assign a fixed IP instead of using DHCP.
I now here have 3 VMs on my Windows 8 machine, some use fixed IP and some use DHCP and they all work fine. The important part is to make sure your router does not have settings to assign a particular IP for a particular MAC address.
Good luck!
Francois
Thanks. Reservation is not configured in the router - I have the option of specifying a MAC address and assigning an IP, but the table is blank. I'm guessing it mayb defaults to it? It's a router from the local ISP.
In the advanced option of the virtual adapter in Hyper VM, I selected a static MAC. For whatever reason, the VM now has it's own IP address, X.X.X.7. Host is X.X.X.3
2 strange things though.
1. I can only access the router config page (X.X.X.1) via the VM. On the host, each time I try to login, it kicks me out. It's a Cox branded Netgear router (from ISP). Once I shutdown the VM, I can access the router config page on the host.
2. When looking at the list of connected clients in the router, it only shows the Machine name for the host - however, the corresponding IP address shown is that of the VM.
Weird ...
Anyway, not so concerned with having it work at home - it will be more so for at work.

IP Address Conflict with range expander

Hi,
I have a Linksys WRT610N router that I am trying to extend the range of using a Hawking HWREN1. The router configures fine and I'm able to access the Internet from an attached PC. When I hook up the Hawking extender, it configures correctly, it seems, but as soon as it saves the configuration, Windows XP on the PC tells me that there is an IP address conflict.
Hawking suggested a factory reset of the extender and redoing setup, which I did, with no success. As soon as I unplug power to the extender, the error goes away, so the issue is connected to the extender.
I've also tried using a completely different IP address range, setting the router to 192.168.2.2. The PC is set to 192.168.2.201, and the extender to 192.168.2.202, and still I get the IP address error message.
I'm unsure how to perform further diagnostics on this, since at least from the looks of things, there is no IP address conflict, even tho the error message says that there is. Is there something else that could cause an IP address conflict besides the IP address itself, for example? BTW, the extender was purchased on advice of a store clerk, who said that they'd had good luck with the Hawkings. Is there a more appropriate product to use from Linksys. Supposedly, the Hawking is better because it covers a larger variety of standards, even tho it is not dual band like the router. I haven't seen any dual band extenders around.
Any help would be appreciated.
Thanks.
Ron
Solved!
Go to Solution.

If you are getting these error mesasge on your Computer, these means your Both the computers are getting the same IP address from the Router. To avoide getting these error message, you can assigne a Static IP to your Hardwired Computer.
On your XP computer follow the settings bellow. Click on the Start button >>> Settings >>> Control Panel >>>Network Connections- Right click on the icon for Local area connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the following IP address'- Provide IP Address - 192.168.1.5, Subnet Mask - 255.255.255.0, Default Gateway - 192.168.1.1- Preferred DNS 192.168.1.1, Alternate DNS - 4.2.2.2 >>Click on Ok button to Save and Click on "Close" on main Properties window.
Now check if you are Online from your computer, and i think these should solve your Problem.

Hi,
I am unable to add my bank/card details in my apple account, every time i am getting a message that it has been declined. kindly help me in authorise my bank card in my apple account i need to purchase few apps, pls help me

What sort of card are you trying to use ? If it's a debit card then I don't think that they are still accepted as a valid payment method - they are not listed on this page and there have been a number of posts recently about them being declined
If it's a credit card then is it registered to exactly the same name and address (including format and spacing etc) that you have on your iTunes account, it was issued by a bank in your country and you are currently in that country ? If it is then you could check with the card issuer to see if it's them that are declining it, and if not then try contacting iTunes support and see if they know why it's being declined : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management

This never happened before, however the last couple of months it comes up every time I plug my USB from PC to iphone.

HyperNova Software,
Thank you so much. Because I am very computer illiterate, could you help me on how to get started? I don't have the slightest on where to get started, the steps to follow, etc.
Can't thank you enough for your help!
