I am having troubles connecting to a wireless network when the SSID is not broadcasted. When I broadcast the SSID, the connection works perfectly but the setup needs to be without broadcasting.
The problem occurs on IBM Linovo R60 and R52 desktops. When I manually try to add the wireless network I can enter the correct SSID and network key, but when I finish the wizard I get the message "the wizard could not create a wireless network".
Adding the network without the wizard (in properties of the wireless card) does not work. Adding the network by copying the settings on USB stick from a laptop where it does work (mine: a HP nc6120) gives the same error message.
I have updated the drivers for the wireless NIC of the IBM's to the latest version.
Wireless network settings: Authentication: WPA-PSK, Encryption: Auto.
When using WEP encryption I get the same problem.
One strange thing: when i reboot one of the IBM's, import the wireless connection settings from the USB and restart the "Wireless Zero Configuration" service the wireless connection comes up ont time. After a disconnect or reboot it doesn't work anymore.
