I'm trying to set up Wi-Fi on my BlackBerry 8120.
This is the forst time I've owned a BlackBerry device, so I'm new at this.

Anyway, I start off at 'MANAGE CONNECTIONS'
*Switch the wifi on
*Cick on 'SET UP WIFI NETWORK'
*I click on 'NEXT'.

I then scan for networks and it finds my network.
I then enter my PSK key.

After it tries to connect to the network, it tells me that it 'failed to authenticate against the network'??

It also says that many wifi hotspots require registration.

How can I do this?
Many thanks...
