I have a dell Insperion 9400 laptop which uses the Intel PROSet/Wireless software for connecting to wireless networks. It has recently started giving me the error message "Problem applying profile" when I try to connect to a network. Sometimes when I reboot the computer the problem goes away until I change networks. I've tried deleting all the wireless profiles and re-adding them (home and work), but this doesn't seem to solve the problem. I've also tried upgrading to the latest version (22.214.171.124) that's available from the Dell support site.
