I upgraded my T500 to Windows 7 Professional from Vista Business. Since upgrading, I have been unable to obtain satisfactory WiFi connectivity. Symptoms are that I cannot stream from either the internet or my local server without experiencing periodic interruptions and/or total drops. I've tried reinstalling the driver, replacing the WiFi card itself, and adjusting the parameters associated with the adapter card. Nothing seems to help. I also own a T61 laptop which I also upgraded from Vista Business to Windows 7 Professional, and I have had no problems with WiFi connectivity on that machine. It also has an Intel Wifi adapter but a different model. Both laptops connect to my LAN and the internet through the same D-Link wireless access router.
I'm beginning to suspect that the Windows 7 driver for this particular WiFi adapter is flawed. Has anyone in this forum had a similar experience?
Thanks in advance for your comments/assistance.

try to use your laptop without 'energy star'. setup full speed processor to maximum.
I thinks the problem turn around win7 and 'energy saving driver'
