This error comes up because WINXP's wireless manager is running at the same time as the Intel/PRO version:
Another wireless network utility is communicating with the Intel PRO/Wireless adapter. To avoid conflicts, Intel's profile management features have been temporarily disabled.
There is no way to disable the WinXP manager - the checkbox doesn't work. And the XP manager is much worse than the Intel/PRO. How do I disable or uninstall the WINXP Manager?
