Bt home hub?
Answer:
Sounds for a while like the DSL routers some of us hold here in the US. Typically one of those numbers IS the WEP knob, but you have to form sure you are punching in the right one. Did you thieve a look here: http://www.shop.bt.com/content/ebiz/btsh...
My next suggestion would be to jump into the device via a web browser and check for something that say "security" or "wireless" and see if you can then find what you involve.
