BT4 on Netbook

Hi guys

I need some help with running BT4 on my Acer Aspire netbook, everything works fine except my wireless wouldn't start when I login into BT4 KDE. When I do iwconfig it shows me ath0 next to it some madwifi details. How do I turn on my wireless to work with BT4? :confused:

My wireless details are as follows "Atheros AR5006EG 802.11b/g".

Any suggestions?

Many thanks.

/etc/init.d/networking start

or try using the search button?
