I have had a Belkin Pre-N router and a Pre-N notebook card for several months now. Up until recently, my laptop has been running Windows 2000, and I was forced to use a free WPA-PSK client available from McAfee in order to support WPS-PSK security. In any event, I've had rather flawless connectivity and excellent data rates with the Pre-N using WPA-PSK.
The other day, I decided to upgrade the OS on the laptop to XP(SP2). After a fresh install of XP, I installed the Pre-N notebook card software and drivers. Since then, I've had absolutely lousy connectivity either by using the Belkin application, or by letting Windows manage the wireless connection. When I do achieve connectivity, it's at a few Kbps - even when in the same room with the router. Does anyone have any suggestions as to what may be wrong with my configuration, and what I might do to to correct it? Thanks.
