I have a dual boot system with Vista 64 and windows 7 64bit, on an HP pravilon Elite D5000t with 8 gig ram, Quad core 9450 2.83, two 750g hard drives and according to HP a starling 802.11 a/b/g/n wireless PCI express card. Both vista and W7 recognize this wireless adapter as foxconn 802.11 a/b/g/n with Atheros drivers. The wireless adapter connects at 300mb on the windows 64 system and any where from 1mb to 48mb on windows 7. I located the vista 64 drivers for the card but windows 7 will not let me install the previous version. Windows 7 states drivers up to date. I uninstalled the card and attempted a reinstall and Windows 7 drivers automatically installed. I had the same issues as several other users with Internet connectivity dropping sites. Checking the wireless status I found the connection to network and internet statusconnected, but at 1mb. I know this is a driver issue, but can not solve this annoying problem.

Hey,Can you try uninstalling the driver, and install the Vista driver using the "Have Disk" option under "Update Driver" in Windows 7? If it doesn't work, make sure that the INF file (that is part of the Vista x64 driver) has the correct hardware ID of your wireless adapter.Let me know if you are lost, and I'll explain in detailed.Jabez Gan [MVP] - http://www.msblog.org

I attempted to uninstall drivers several times and each time I had the same issue windows 7 wanted to load its own. I finally took the big plung and removed all inf files in the windows directory, system 32 driver, and driverstore directory replaced each with the appropriate sys and inf file. rebooted and of course the wireless card did not respond. when to device manager and it gave the following message, device driver not digitally signed. updated driver with the vista driver thru update and now I am at 300mb. I appreciated your insight. I had totally forgotten all the inf files that are created. Thanks
