I must be old fashioned but my repeating setup is like this.

Router:
1. Latest firmware.
2. Enable SSID broadcast.
3. Enable WPA-PSK and choose a password.

Laptop/other:
1. Use the wizard.
2. Supply the password.

Never a problem. There are those that disable SSID or use MAC filtering so we have to wait for them to come around and try what works for us.
