I can't help with this, except to confirm I'm seeing the same thing. I have a Gigabyte GA-EP45-UD3P that also has the RealTek LAN adapter.

Do you have any devices attached to your phone line? Perhaps a satellite TV box?.

I'm sorry that I don't have an answer for you either. I, also, have to say that I'm starting to see this problem.

Well, we can rule out thadhcpt the router is assigning static IP addresses. Routers will only assign static addresses if they are set as a static ip address not dhcp. It could be that there is some code or syntax in Win 7 and network configuration and execution software that is causing this. Look it'stwo differant routers and two differant computers. My router is a DLink DI-634M and my computer is a Toshoba Satellite 1.46Ghz, 2Gb RAMAPlusTech

Do you have any devices attached to your phone line? Perhaps a satellite TV box?. hiya all i have noticed this problem myself and wondering what it could be why do you ask if a Sat box is connected? as i have sky tv and also use sky broadband would this be the problem? i am running windows 7 ultimate 32 bit and 64bit on main pc my route is the SMC7904WBRA-N, and run a home network but have never noticed this in my logs before, is it anything to be concerned with? many thanks Darkman

I am also having this problem with Event Viewer. Router Advertisement settings have been changed on the network adapter 14. The current M - Managed Address Configuration flag is false and the O - Other Stateful Configuration flag is false. User Action: If you are seeing this event frequently, then it could be due to frequent change in M and O flag settings on the router in the network. Please contact your network administrator to have it resolved. I am running Windows 7, Home Premium SP1 64-bit operating system on my HP Computer. Am wondering if anyone ever found a solution? Thanks! Crystal Crystal Darnall
