BT VOYAGER 2110 - WIRELESS SETUP

[#1]

Please can somebody help me.  Back in January upgraded to this but have since not been able to wirelessly connect laptops.  However, both laptops are able to connect to other wireless systems.
Does anyone know what the problem could be?
Also SSID - need to sort this out too.
Need to up from WEP to WPA2 - how do I do this?
Sorry to appear such an idiot
