I am using W7 on my Dell Precision workstation with a 3rd. party Wifi PCI card. The connection to the WAP will not connect automatically, even with the check-box marked for this, and after connection drops the access within seconds. It does reconnect but then drops again frequently even if there is no internet activity. I have set up W7 as a complete new install on this PC, previously using XP pro on the same machine / card etc. without any of these problems. This problem currently stops any consistency in downloading updates etc.

This issue occurs if the installed driver is not compatible. I suggest that you download the latest network adapter driver from Dell website. However, since currently the latest driver can be for Windows Vista, if the issue persists after installing the driver, we may need to wait for new drivers from the manufacturer. In this case, I suggest that you try to disable auto-tuning to check if it would help. To disable auto-tuning, please launch cmd with high privilege, and enter the following command. netsh int tcp set global autotuninglevel=disableArthur Xie - MSFT
