Dell Inspiron 9100 - No wireless

[Jonathan Thompson]

Hi,

I have got Hoary up and running on my Dell laptop (Inspiron 9100)
every thing appears to be working, even bluetooth but there is no
wireless at all and no indication that it even exists. The wired
connection works just fine. Wireless is the Broadcom 1450 801.11 b/g
card.

I am a newbie and have no idea even where to start. Please can someone
push me in the right direction.

Regards,

Paul
