Hello, Before we go further, I would like to confirm the following questions: 1. Would you please let me know the installed update name or number? Is it a NIC driver update? 2. How does the computer connect to Internet, via DSL or router? At this stage, you might go to Device Manager, right click your hardware device in the list and select Update Driver Software; then click Search automatically for updated driver software. Note: Drivers on the Windows Update site are directly provided by hardware manufacturers. Microsoft tests drivers in various environments before they are published; however, we cannot guarantee all drivers will work on all hardware platforms as there are too many different models, although their hardware ID are the same as the standard version. In some cases, due to hardware modifications by different manufacturers, the driver updates may cause some error. If it still does not work on your issue, I'd suggest you installing the Vista driver in Compatibility mode. Remove and rescan that hardware device in Device Manager, right-click on the driver executable/installer file -> Properties and select the Compatibility tab; click the checkbox before Run this program in Compatibility mode for option and select Windows Vista in the list-down box; then try installing the device driver via Run as administrator. In addition, you can use the Windows XP driver for testing. Meanwhile, please also temporarily turn off firewall on the computer and router (If it has) to check the status. Thanks, Novak
