Be aware that the Intel® PROSet/Wireless Connection software won’t provide PLC (Pre-Logon Connect and Persistent Connection) service under Windows* 7 32 or 64Bit.
If you would like that feature then you should use Windows* 7 own connectivity software to accomplish it.
Just wondering if there is a solution to this as we are having the exact same issue here. We are implementing 802.1x, and once we import the wireless profile created by the Proset Admin Utility, we have to click "Other User" before the login screen appears.
If we manually configure the 802.1x connection without using a proset profile, we have no problem. Since we need to configure about 5000 computers we need to use the profile.
