Remove SP3 for XP. Service Pack 2 is the highest you can run if you want stable wireless.

"General advice is to make sure you have the most up to date Wireless drivers from the WiFi card vendor. You should also try disabling power management features within the cards driver. If you are having this sort of problem it can mean that there is a problem with your WiFi card and the infrastucture you are connecting to negotiating power levels. The Intel Centrino WiFi (the Pro Wireless 2100b) in the T-42 had issues with PSP Mode (Power Save Polling) with early driver versions when connecting to quite a few vendors' Access Points, it was definitely an issue with older Cisco kit. The recommendation was to either enable CAM (Continually Aware Mode)\disable PSPM if those options are available or to simply set the WiFi power level to max. This should not be an issue with the most current drivers but it is always worth checking, just in case your AP has issues handling PSPM.

There is some additional information on the broader subject in this TechRepublic article."

Are you using the thinkvantage connection manager or the built in windows wireless settings app? I've had problems with some of the newer thinkvantage updates (i tend to keep the old version as a result) - try switching to letting windows handle it and see if that fixes it. If it does, see if you can revert to an older version - there's usually installers for them in the drivers folder at the installation root.
