I just did a clean install of Windows 7 Professional (64 bit). Everything loaded fine, but my internet connection is running a lot slower than it did under Vista 32 bit Ultimate. I've tried re-loading the old Vista driver, loading the latest one from Windows Update, turning off auto-tuning, but nothing seems to help. Downloads that used to hit 200kbps are now topping out close to 24kbps. I've tried turning off all security to my access point and leaving it wide open, but that doesn't help either. The network adapter is a WUSB600N version 1 from Linksys.
