downloaded windows7 to my d600, but it does not recogize any network connectivity. Help.

This issue occurs if the network adapter driver does not work properly. I suggest that you uninstall the driver, download the latest driver and install it. Uninstall. 1. Launch Device Manager, expand the branch Network Adapters. 2. Double-click on the NIC, in the Drivers tab, select to delete the driver.3. Open Control Panel/Program and Features. 4. Uninstall programs related to the network adapter. Then download the latest driver from the following website.
