Windows Error: Windows has detected an IP Address conflict ...

IP address conflict error message. My internet provider is Verizon and it requires a Pantech UML290 USB modem. When connecting with this device at the time of the connection I get a pop up message "Windows has detected an IP address conflict ..." and then disconnects. I found that when connecting if I reconnect several times it will stay connected. After disconnecting, if I try to connect again I get the same error message. I have removed the built in Wireless adapter, but I still get the same results each time on connection. I have contacted Verizon and they said it was a problem with my computer not their hardware.

ASUS CM1831 (Windows 7 64bit)

Pantech UML290 (Verizon Wireless USB modem)

Here is where I checked ipconfig/all

The exact same problem started happening to me about two weeks ago.  I have the same modem from Verizon and use Windows 7.  Everything that I find through online searches says that the problem is in the network - but I have no network and no other computer running in the house.  This is a minor annoyance but still an annoyance.

I was able to fix my problem on my own. After talking to Verizon (they said nothing wrong with the modem but to take my computer to get it fixed by a repair professional) and ASUS (they said buy another modem to see if the same thing happens with a new one).

Anyway, I went into VZAccess Manager
Click on "Menu"
Click on "Options"
Click on "Preferences"
In the "Connect Menu" under "Device operating mode" mine was set to "Windows Mobile Broadband". I Changed that to "LAN Adapter" and under "Device connection preferences" make sure it is set to "LAN Adapter - Manually Connect".
Then Click "OK"

Again mine is working with no error pop ups.

Still, I think there is a bug that was introduced by either a Verizon or Windows update.  My previous settings had worked well for years.  Things like that don't just stop working.

I am, all of a sudden, having a similar issue.  It is a Microsoft thing, because my linux box is not having the same problem.  Is this happening to anyone else??  A network issue I would expect all device to have the same problem.  Most everything uses DHCP and the network scope is broken in half.  Lower range for statics - upper range for DHCP.

I have exactly the same problem.. but this one is really special - since it shows clearly that Microsoft are shipping out a faulty product that people should claim a refund on..
I switched off my pc at 2am after being on the internet and switched it back on again at 8am. At 8.06 am Windows 7 reported that I had an ip conflict and then showed 'unidentified network' both of which mean absolutely nothing to me. The router is ON permanently , has been for a long time. 
The only device on the network, as registered by my router, is the ONE PC that I turned on at 8am.
Now, tell me please Microsoft. What has changed between 2am and 8am on a PC that has been working fine for over 6 months since I re-installed everything on anew PC?
I switched on another old Visa PC on the network and that worked ok, it got its IP , NO CONFLICT REPORTED, and I am able to type this message as a result.
But as for the Windows 7 PC with 16GIG RAm etc etc etc, all totally overkill for a crippled product from Bill gates, it no longer serves a useful purpose..
Now, I will be contacting the UK office of Microsoft tomorrow and asking for a refund on my product and I will be making this a very public issue.
Microsoft software does not seem to be a reliable product and I would advise all disgruntled users to ask for their money back 
My internet provider is BT
