Uninstall, then reinstall the software for the wireless adapter.
Then run the WinsockXPFix tool from the link below to repair any connection software that may be damaged:
And have you checked for malware? Try downloading, installing, updating, then running the free SuperAntispyware program from the links below.. On a separate, clean computer, download the installer file and manual updater from the links below.. Copy them to a CD or flash drive, then transfer them to the problem machine. Run the installer file to install the program, then bring it current by running the manual updater.. Once that's done, run a full system scan.

Hope this helps.
In my home I have wireless adsl for laptops, and I got a dlink wireless dongle for my desktop, (P4 3Ghz, 2Gb ram, windows XP)
It worked fine until automatic update installed service pack 3.
unfortunately at the same time I installed VMwareworkstation. I assumed vmWare was the problem so I removed it, but the problem remains.
The wireless connection manager says it is connected (usually at first there is the bubble saying "limited or no connectivity" but then it says connected. But no internet browsers or other programs are able to access the internet.
I've tried everything I can think of...is it on option to simply uninstall SP3? or would that kill my system?
