I have a stubborn problem with an Acer 5040 laptop. It has stopped connecting to my wireless network when using Windows XP. Wireless works if I boot into Linux from a USB drive, so it is not a hardware failure.
Network shows up when I View Available Wireless Networks. Signal strength is OK but will not connect. Other computers connect without problem.
I have tried a number of things: ipconfig /release; ipconfig /renew; ipconfig /flushdns; Delete wireless connection from list and start over; Run wireless wizzard on other computer and use USB to apply settings; Disable ZoneAlarm firewall; Disable wireless security; Use USB wireless dongle in place of internal wireless; System restore.
None of the above have helped me to connect using Windows. I am looking for suggestions for other things to try?
