IP Address Conflict Using Mobile Hotspot On Iphone 5

Hello,

I just got my new Iphone 5 and I love it, apart from one little problem. Now when I connect it to my laptop using the mobile hotspot (either via usb or wireless) I am constantly getting a network error popup stating that there is an ip address conflict.

Hardware info:

Iphone 5 16gb

Asus G74S Laptop with Windows 7 64bit

Error info:

The error popup is in the form of a small window titled Network Error. It states "Windows has detected an IP address conflict" "Another computer on this network has the same IP address as this computer... blah blah blah"

The windows system event viewer has the following log:

Source is Tcpip

The system detected an address conflict for IP address :: with the system having network hardware address 00-00-00-00-00-00. Network operations on this system may be disrupted as a result.

The event ID is 4199

Done so far:

Already did every single troubleshooting step in regards to ip address conflicts, ipconfig /release and /renew, flush dns etc. I even did an entire system restore on my laptop back to factory settings. Installed a fresh Itunes 10.7 64bit and reconnected my new Iphone 5 and am still getting this message. I never had this problem with my Iphone 4.

Called Apple tech support, they ran me through all the steps relating to the phone itself, reseting network settings, resetting factory settings, removing and re-inserting the sim card, you name it.

Disabled IPv6 in the registry and reboot, still the same popup occurs.

Tried to assign a static IP address to Ipv4, still the same popup

Any ideas?

iPhone 5, iOS 6

Still having the same issue....Is there another thread in which this is resolved? Iphone 5, IOS 6. It's just the phone tethered to a laptop (have tried with two laptops, both get the ip address conflict error, so the problem resides in the phone). No other devices are on the network. Was this ever addressed?

We use the iphone 5 as a mobile hotspot for our business, which is completely internet/skype based, and we need to be mobile. Mifi keeps kicking off the connection, so they are not an option. Thank you.

I'm having the exact same problem on my Verizon Wireless iPhone 5. It wasn't initially a problem and tethering worked fine, but something has changed and started causing it. Ugh, it's really annoying. The event log entry about 00-00-00-00-00-00 doesn't give me any useful information so it's hard to troubleshoot.

Actually, I believe I just fixed it by going to Network and Sharing Center -> Change adapter settings -> Whatever the iPhone device is -> Properties -> unchecking Internet Protocol Version 6 (TCP/IPv6). After unchecking it, I haven't had the message come back. Then, I turned it back on and the message popped up almost immediately. So I'm pretty sure it's an IPv6 thing, at least in my case.

Doug for the win. Disabling IPv6 corrected the duplicate IP address error for me as well.

SUCCESS - thanks Doug Big Brain Brown!

unchecking Internet Protocol Version 6 (TCP/IPv6) did not affect any use of my USB hotspot use on Iphone5 on my Verizon network....but did eliminate the MS Windows 7 popup error about IP address conflict.

Thanks Doug! I just got an iPhone 6 Plus on Verizon. I was previously using an iPhone 5 on ATT and didn't have an issue. Disabled IPv6 and corrected the problem. Thanks!

Thanks! Your solution worked for me too. I'm using my iPhone 5 with a Windows 7 laptop. Interesting detail is that it all worked fine for several days before I started getting the device ip conflict error. Not sure if it's related but a day or two prior to the ip address conflict message, I started noticing multiple connections to the iPhone Hotspot, 1st 2 then 3? So far, the 3 connections are persisting, even after disabling ipv6 on the adaptor.
