I am running Win7 64 bit I have a marvell yukon nic and a netgear rangemax router, I upgraded to win7 64bit from 32bit, The connection worked before the upgrade, have tried re-installing software/drivers etc, but still no luck. I get Unidentified Network and no internet access.mikey

Hi Mikey Have you upgraded all of the hardware drivers to the 64bit versions? The 32bit drivers will no longer work on the system. Let us know. Thank You for using Windows 7 Ronnie Vernon MVP

Hi, I also would like to suggest you update the firmware of the router to check the issue. According to the router, you may try to assign a static IP address to test the issue. If the issue persists, you may also try the steps the following thread mentions to troubleshoot the issue. http://social.technet.microsoft.com/Forums/en/w7itpronetworking/thread/662e5ac6-b0c2-48e6-8a86-a00eaa9c4ba1 Regards,Arthur Li - MSFT

Thanks for all the great info guys. I finally just re-installed the OS and got a better Network card (10/100/1000). All my driver are up to date and I am no longer having problems.mikey
